Devices are listed in the table of contents alpha-numerically by device family (LH, LM, LX, etc_) and then by device number.
With most of National's proprietary linear circuits, a 1-2-3 numbering system is employed. The 1 denotes a Military temperature
range device (---SSoC to +12Soe), the 2 denotes an Industrial temperature range device (-2SoC to +8SoC), and the 3 denotes a
Commercial temperature range device (OOe to +70oel. i_e_ LM101/LM201/LM301.
Exceptions to this are the LM1800 series of consumer circuits which are specified for the commercial temperature range;
some hybrid circuits which employ a "C" suffix to denote the commercial temperature range; and second-source proclucts
which follow the original manufacturers numbering system, i.e. LM74l/LM741C or LM1414/LM1S14.
Parts are generally listed in the table of contents by military part number first, i.e. LM139/LM239/LM339. Where a separate
data sheet exists for a different temperature range, the device will be listed separately, i.e. LM119/LM2l9 and listed separately
LM3l9. Where only one temperature range exists, the part will be listed in its proper order, i.e. LM340.

LM100/LM200/LM300 voltage regulator
general description
The LM100, LM200 and LM300 are integrated
voltage regulators designed for a wide range of
applications from digital power supplies to precision regulators for analog circuitry. Built on a
single silicon chip, these devices are encapsulated
in either an 8·lead, low profile TO-5 header or a
1/4 x 1/4 metal flat package. Outstanding char·
acteristics are:
• Output voltage adjustable from 2V to 30V
(LM300 adjustable from 2V to 20V)
• Better than one percent load and line regulation
• One percent temperature stability
• Adjustable short·circuit limiting
• Output currents in excess of 5A possible by
adding external transistors
.......
r-
s:
• Can be used as either a linear or high-efficiency
switching regulator.
CrJ
o
o
Additional features are fast response to both load
and line transients, small standby power dissipa·
tion, freedom from oscillations with varying
resistive and reactive loads, and the ability to start
reliably on any load within rating.
The LM100 is specified for operation over the
_55°C to +125°C military temperature range. The
LM200 and LM300 are low cost, commercial·
industrial versions of the LM 100. They are identical
to the LM 100 except that they are specified for
operation from -25°C to 85°C and from O°C to
70°C respectively.

Note1: The maximum junction temperature of the LM100 is 150°C, while that of the LM200 is
lOOoe, and the LM300 is 85°C. For operating at elevated temperatures, deVices In the TO-5 package
must be derated based on a thermal resistance of 150 0 C/W junction to ambient or 45°C/W, junction to
case. For the flat package, the derating is based on a thermal resistance of 185°C/W when mounted on
a 1/16-inch-thick, epoxy-glass board with ten, O.03-inch-wide, 2-ounce copper conductors. Peak
dissipations to 1.0W are allowable providing the dissipation rating is not exceeded with the power
averaged over a five second interval for the LM100 and LM200, and a two second interval for the
LM300.
Note 2: These specifications apply for an operating temperature between _55°C to +125°C for the
LM100, between -25°C to 85°C for the LM200 and between OOC to 70°C for the LM300 devices for
input and output voltages within the ranges given, and for a divider impedance seen by the feedback
terminal of 2 k~l unless otherwise specified. The load and line regulation specifications are for
constant junction temperature. Temperature drift effects must be taken into account separately when
the unit is operating under conditions of high dissipation.
Note 3: The output currents given, as well as the load regulation, can be increased by the addition of
external transistors. The improvement factor will be roughly equal to the composite current gain of
the added transistors.

LM103 regulator diode **
general description
The LM103 is a two-terminal monolithic regulator
diode electrically equivalent to a breakdown diode.
The device makes use of the reverse punch-through
of double-diffused transistors, combined with active circuitry, to produce a breakdown characteristic which is ten times sharper than single-junction
zener diodes at low voltages. Breakdown voltages
from 1.BV to 5.6V are available; and, although the
design is optimized for operation between 100 IlA
and 1 mA, it is completely specified from 10 IlA to
10 mAo Noteworthy features of the device are:
•
Exceptionally sharp breakdown
•
Low dynamic impedance from 10 IlA to 10 mA
• Performance guaranteed over full military temperature range
• Planar, passivated junctions for stable operation
•
Low capacitance_
The LM 103, packaged in a hermetically sealed,
modified TO-46 header is useful in a wide range of
circuit applications from level shifting to simple
voltage regulation. It can also be employed with
operational amplifiers in producing breakpoints to
generate nonlinear transfer functions. Finally, its
unique characteristics recommend it as a reference
element in low voltage power supplies with input
voltages down to 4V.

LM104/LM204 negative regulator
general description
o
The LM104 and LM204 are precision voltage
regulators which can be programmed by a single
external resistor to supply any voltage from 40V
down to zero while operating from a single
unregulated supply. They can also provide
O.Ol-percent regulation in circuits using a separate,
floating bias supply, where the output voltage
is limited only by the breakdown of external
pass transistors. Although designed primarily as
linear, series regulators, the circuits can be used as
switching regulators, current regulators or in a
number of other control applications. Typical
performance characteristics are:
~
• 0.3% temperature stability over military temperature range
The LM 104 and LM204 are complements of the
LM100 and LM105 positive regulators, intended
for systems requiring regulated negative voltages
which have a common ground with the unregulated supply. By themselves, they can deliver.
output currents to 25 mA, but external transistors
can be added to get any desired current. The
output voltage is set by external resistors, and
either constant or foldback current limiting is
made available.
The LM 104 is specified for operation over the
-55°C to +125°C military temperature range. The
LM204 is specified for operation over the -25°C to
+85°C temperature range.
• 1 m V regu lation no load to full load
• 0.01 %IV line regulation
• 0.2 mV IV ripple rejection

LM304 negative regulator
general description
The LM304 is a precision voltage regulator which
can be programmed by a single external resistor to
supply any voltage from 30V down to zero while
operating from a single unregulated supply. It can
also provide O.Ol·percent regulation in circuits
using a separate, floating bias supply, where the
output voltage is limited only by the breakdown
of external pass transistors. Although designed
primarily as a linear, series regulator, the circuit
can be used as a switching regulator, a current
regulator or in a number of other control applica·
tions. Typical performance characteristics are:
• 0.2 mV/V ripple rejection
The LM·304 is a complement of the LM300 and
LM305 positive regulators, intended for systems
requiring regulated negative voltages which have a
common ground with the unregulated supply. By
itself, it can deliver output currents to 25 mA, but
external transistors can be added to get any desired current. The output voltage is set by external
resistors, and either constant or foldback current
limiting is made available. The LM304 is a
commercial/industrial version of the LM 104 and
LM204.
• 1 mV regulation no load to full load
• 0.01%/V line regulation

general description
r-
The LM lOS, LM20S and LM30S are positive volt·
age regulators similar to the LM100, except that
an extra gain stage has been added for improved
regulation. A redesign of the biasing circuitry
removes any minimum load current requirement
and at the same time reduces standby current
drain, permitting higher voltage operation. They
are direct, plug·in replacements for the LM 100 in
both linear and switching regulator circuits with
output voltages greater than 4.SV. Important
characteristics of the circuits are:
• Output voltage adjustable from 4.SV to 40V
• Output currents in excess of lOA possible by
adding external transistors
• Load regulation better than 0.1 %, full load with
current limiting
s:W
• DC line regulation guaranteed at 0.03%/V
o
• Ripple rejection of 0.01 %/V
(J1
Like the LM100, they also feature fast response to
both load and Iine transients, freedom from
oscillations with varying resistive and reactive
loads and the ability to start reliably on any load
within rating. The circuits are built on a single
silicon chip and are supplied in either an 8·lead,
TO·S header or a 1/4" x 1/4" metal flat package.
The LM20S is identical to the LM 1OS except that
it is specified for operation from - 2SoC to 8SoC.
The LM30S is specified for operation from DoC to
70° C and for output voltages to 30V.

Note 1: The maximum junction temperature of the LM105 is 150°C, while that for the LM205 is
100°C. and that for the LM305 is 85°C. For operating at elevated temperatures, devices in the TO-5
package must be derated based on e thermal resistance of 150"C/W, junction to ambient. or 45°C/W,
junction to case. For the flat package. the derating is based on a thermal resistance of 185° C/W when
mounted on a 1/16-inch-thick epoxy glass board with ten. O.03-inch-wide. 2-ounce copper conductors.
Peak diSSipations to 1Ware allowable providing the dissipation rating is not exceeded with the power
averaged over a five second interval for the LM105 a'nd LM205, and averaged over a two second
inlerval for the LM305.
Note 2: These specifications apply for input and output voltages within the ranges given, and for a
divider impedance seen by the feedback terminal of 2 kn, unless otherwise specified. The load and
line regulation specifications are for constant junction temperature. Temperature drift effects must be
taken into account separately when the unit is operating under conditions of high dissipation. Unless
otherwise specified. T A = 25°C.
Note 3: The output currents given, as Well as the load regulation, can be increased by the addition of
external transistors. The improvement factor will be roughly equal to the composite current gain of
the added transistors.

LM109/LM209 five-volt regulator
general description
The LM109 and LM209 are complete 5V
regulators fabricated on a single silicon chip. They
are designed for local regulation on digital logic
. cards, eliminating the distribution problems associ·
ated with single-point regulation. The devices are
available in two common transistor packages. In
the solid-kovar TO-5 header, it can deliver output
currents in excess of 200 mA, if adequate heat
sinking is provided. With the TO-3 power package,
the available output current is greater than 1A.
The regulators are essentially blow-out proof.
Current limiting is included to limit the peak
output current to a safe value. In addition, thermal
shutdown is provided to keep the IC from
overheating. If internal dissipation becomes too
great, the regulator wi II shut down to prevent
excessive heating.
response somewhat. Input bypassing is needed,
however, if the regulator is located very far from
the filter capacitor of the power supply. Stability
is also achieved by methods that provide very good
rejection of load or line transients as are usually
seen with TTL logic.
Although designed primarily as a fixed-voltage
regulator, the output of the LM109 and LM209
can be set to voltages above 5V, as shown below.
It is also possible to use the circuits as the control
element in precision regulators, taking advantage
of the good current-handling capability and the
thermal overload protection.
To summarize, outstanding features of the regulator are:
Considerable effort was expended to make these
devices easy to use and minimize the number of
external components. It is not necessary to bypass
the output, although th is does improve transient
• Specified to be complete, worst case, with TTL
and DTL
• Output current in excess of 1A
• Internal thermal overload protection
• No external components required

LM309 five-volt regulator
general description
The LM309 is a complete 5V regulator fabricated
on a single silicon chip. It is designed for local
regulation on digital logic cards, eliminating the
distribution problems associated with single·point
regulation. The device is available in two common
transistor packages. In the solid·kovar TO·5
header, it can deliver output currents in excess of
200 mA, if adequate heat sinking is provided. With
the TO·3 power package, the available output
current is greater than 1A.
The regulator is essentially blow·out proof.
Current limiting is included to limit the peak
output current to a safe value. In addition, thermal
shutdown is provided to keep the IC from
overheating. If internal dissipation becomes too
great, the regulator wi II shut down to prevent
excessive heating.
response somewhat. Input bypassing is needed,
however, if the regulator is located very far from
the filter capacitor of the power supply. Stability
is also achieved by methods that provide very good
rejection of load or line transients as are usually
seen with TTL logic.
Although designed primarily as a fixed·voltage
regulator, the output of the LM309 can be set to
voltages above 5V, as . shown below. It is also
possible to use the circuit as the control element in
precision regulators, taking advantage of the good
current·handling capability and the thermal over·
load protection.
To summarize, outstanding features of the regula·
tor are:
Considerable effort was expended to make the
LM309 easy to use and minimize the number of
external components. It is not necessary to bypass
the output, although this does improve transient
• Specified to be compatible, worst case, with
TTL and DTL
• Output current in excess of 1 A
• Internal thermal overload protection
• No external components required

LM113 reference diode
general description
The LM 113 is a temperature-compensated, lowvoltage reference diode_ It features extremely-tight
regulation over a wide range of operating currents
in addition to an unusually-low breakdown voltage
and good temperature stability_
The diode is synthesized using transistors and resistors in a monolithic integrated circuit_ As such, it
has the same low noise and long term stability as
modern IC op amps_ Further, output voltage of
the reference depends only on highly-predictable
properties of components in the IC; so it can be
manufactured and supplied to tight tolerances.
Outstanding features include:
•
Low breakdown voltage: 1.220V
• Dynamic impedance of 0_3n from 500llA to
20mA
• Temperature stability typically 1% over -55°C
to 125°C range
• Tight tolerance: ±5% standard, ±2% and ±1%
on special order.
The characteristics of this reference recommend it
for use in bias-regulation circuitry, in low-voltage
power supplies or in battery powered equipment.
The fact that the breakdown voltage is equal to a
physical property of sil icon-the energy-band-gap
voltage-makes it useful for many temperaturecompensation and temperature-measurement
functions.

Note 1: For operating at elevated temperatures, the device must be derated based on a 150°C
maximum junction and a thermal resistance of 80 0 C/W junction to case or 440 oC/W junction to
ambient.
Note 2: These specifications apply for T A = 25°C, unless stated otherwise. At high currents,
breakdown voltage should be measured with lead lengths less than 1/4 inch. Kelvin contact sockets are
also recommended. The diode should not be operated with shunt capacitances between 200 pF and
0.1 /-LF, unless isolated by at least a lOOn resistor, as it may oscillate at some currents.

LM120 series three-terminal negative regulators
general description
The LM120 Series are three·terminal negative regulators with a fixed output voltage of -SV, -S.2V,
-12V, and -1SV and up to 1.SA load current capability. These devices need only one external component - a compensation capacitor at the output,
making them easy to apply. Worst case guarantees
on output voltage deviation due to any combination of line, load or temperature variation assure
satisfactory system operation.
grammed for higher output voltages with a simple
resistive divider. The low quiescent drain current of
the devices allows this technique to be used with
good regulation.
Exceptional effort has been made to make the
LM 120 Series immune to overload conditions.
The regulators have current limiting which is independent of temperature, combined with thermal
overload protection. I nternal current limiting protects against momentary faults while thermal shutdown prevents junction temperatures from exceeding safe limits during prolonged overloads.

LM320T series three-terminal negative regulators
general description
The LM320T Series are three·terminal negative regulators
with a fixed output voltage of -5V, -5.2V, -6V, -8V,
-12V, -15V, -18V, -24V and up to 1.5A load current
capability. These devices need only one external com·
ponent-a compensation capacitor at the output, making
them easy to apply. Worst case guarantees an output
voltage deviation due to any combination of line, load
or temperature variation assure satisfactory system
operation.
Exceptional effort has been made to make the LM320T
Series immune to overload conditions. The regulators
have current limiting which is independent of tempera·
ture, combined with thermal overload protection. Internal
current limiting protects against momentary faults while
thermal shutdown prevents junction temperatures from
exceeding safe limits during prolonged overloads.
Although primarily intended for fixed output voltage
applications, the LM320T Series may be programmed
for higher output voltages with a simple resistive divider.
The low quiescent drain current of the devices allows
this technique to be used with good regulation.
The LM320T Series is packaged in the easy to use
Epoxy B TO·220 rated at 15 watts dissipation.

LM123/LM223/LM323 3 amp - 5 volt positive regulator
general description
....~
.......
The LM 123 is a three-terminal positive regulator
with a preset SV output and a load driving capability of 3 amps. New circuit design and processing
techniques are used to provide the high output
current without sacrificing the regulation characteristics of lower current devices.
CW)
N
.-
~
....
The 3 amp regulator is virtually blowout proof.
Current limiting, power limiting, and thermal
shutdown provide the same high level of reliability
obtained with these techniques in the LM 109
1 amp regulator.
No external components are required for operation
of the LM 123. If the device is more than 4 inches
from the filter capacitor, however, a lJ..LF solid
tantalum capacitor should be used on the input.
A O.IJ..LF or larger capacitor may be used on the
output to reduce load transient spikes created by
fast switching digital logic, or to swamp out stray
load capacitance.
An overall worst case specification for the combined
effects of input voltage, load currents, ambient
temperature, and power dissipation ensure that
the LM 123 will perform satisfactorily as a system
element.
Operation is guaranteed over the junction temperature range -SS~C to +IS0°C. An electrically
identical LM223 operates from -2SoC to +IS0°C
and the LM323 is specified from O°C to +125°C
junction temperature. A hermetic TO-3 package is
used for high reliab.ility and low thermal resistance.

Voltage Regulators
LM145/LM245ILM345 negative three amp regulator
general description
The LM 145 is a three·terminal negative regulator with a
fixed output voltage of -5V or -5.2V, and up to 3A load
current capability. This device needs only one external
component-a compensation capacitor at the output.
making it easy to apply. Worst case guarantees on output
voltage deviation due to any combination of line, load
or temperature variation assure satisfactory system
operation.
Exceptional effort has been made to make the LM145
immune to overload conditions. The regulator has cur·
rent limiting which is independent of temperature,
combined with thermal overload protection. Internal
current limiting protects against momentary faults while
thermal shutdown prevents junction temperatures from
exceeding safe limits during prolonged overloads.
Although primarily intended for fixed output voltage
applications, the LM145 may be programmed for higher
output voltages with a simple resistive divider. The low
quiescent drain current of the device allows this tech·
nique to be used with good regulation.
The LM 145 comes in a hermetic TO·3 package rated at
25W. Two reduced temperature range parts, LM245 and
LM345, are also available.
features
• Output voltage accurate to better than ±2%
• Current limit constant with temperature
• Internal thermal shutdown protection
• Operates with input·output voltage differential of 2.8V
at full rated load over full temperature range
• Regulation guaranteed with 25W power dissipation
• 3A output current guaranteed
• Only one external component needed

Note 1: Unless otherwise specified, these specifications apply: -55°C ::; Tj ::; +150°C for the LM145; -25°C::; Tj::; +150°C for the LM245 and
O°C::; Tj ::; +125°C for the LM345. VIN = -7.5V and lOUT = 5 mAo Although power dissipation is internally limited, electrical specifications apply
only for power levels up to 25W. For calculations of- junction temperature rise due to power dissipation, use a thermal resistance of 3So C/W for
the TO-3 with no heat sink. With a heat sink, use 2°C/W for junction to case thermal resistance.
Not8 2: Regulation is measured at constant junction temperature. Changes in output voltage due to heating effects must be taken into account
separately. To ensure constant junction temperature, pulse testing with a low duty cycle is used.

LM341 series three terminal positive regulators
general desc.ription
Considerable effort was expended to make the LM34l-XX
series of regulators easy to use and minimize the number
of external components. It is not necessary to bypass
the output, although this does improve transient response.
Input bypassing is needed only if the regulator is located
far from the filter capacitor of the power supply.
The LM341-XX series of three terminal regulators is
available with several fixed output voltages making them
useful in a wide range of applications. One of these is
local on card regulation, eliminating the distribution
problems associated with single point regulation. The
voltages available allow these regulators to be used in
logic systems, instrumentation, HiFi, and other solid
state electronic equipment . .Although designed primarily
as fixed voltage regulators these devices can be used
with external components to obtain adjustable voltages
and currents.

•
The LM341-XX series is available in the plastic TO-202
package. This package allows these regulators to deliver
over O.5A if adequate heat sinking is provided. Even
with over O.5A of output current available the regulators
are essentially blow-out proof. Current limiting is included
to limit the peak output current to a safe value. Safe
area protection for the output transistor is provided to
limit internal power dissipation. If internal power dissipation becomes too high for the heat sinking provided,
the thermal shutdown circuit takes over preventing the
IC from overheating.
Output current in excess of O.5A
Internal thermal overload protection
No 'external components required.

Voltage Regulators
LM342 series three terminal positive regulators
general description
The LM342-XX series of three terminal regulators is
available with several fixed output voltages making them
useful in a wide range of applications_ One of these is
local on card regulation, eliminating the distribution
problems associated with single point regulation_ The
voltages available allow these regulators to be used in
logic systems, instrumentation, HiFi, and other solid
state electronic equipment. Although designed primarily
as fixed voltage regulators these devices can be used
with external components to obtain adjustable voltages
and currents.
The LM342-XX series is available in the plastic TO-202
package. This package allows these regulators to deliver
over O.2A if adequate heat sinking is provided. Even
with over O.2A of output current available the regulators
are essentially blow-out proof. Current limiting is included
to limit the peak output current to a safe value. Safe
area protection for the output transistor is provided to
limit internal power dissipation. If internal power dissipation becomes too high for the heat sinking provided,
the thermal shutdown circuit takes over preventing the
IC from overheating.
Considerable effort was expended to make the LM342-XX
series of regulators easy to use and minimize the number
of external components. It is not necessary to bypass
the output, although this does improve transient response.
Input bypassing is needed only if the regulator is located
far from the filter capacitor of the power supply.

LM376 voltage regulator
general description
The LM376 is a positive voltage regulator designed
primarily for commercial product applications. The
device is especially useful because it is packaged in
an 8'pin mini·DIP which has the advantage of
reduced size and low cost. Used independently,
the device will supply 25 mA; but with the addi·
tion of external pass elements any desired load
current can be achieved. The circuit features ex·
tremely low standby current drain, and provision
is made for either linear or foldback current
limiting. Important characteristics of the LM376
are:
+5V to 37V

LM723/LM723C voltage regulator
(')
general description
The LM723/LM723C is a voltage regulator designed primarily for series regulator applications. By
itself, it will supply output currents up to 150 mA;
but external transistors can be added to' provide
any desired load current. The circuit features extremely low standby current drain, and provision
is made for either linear or foldback current limiting. Important characteristics are:
•
150 mA output current without external pass
transistor
•
Output currents in excess of lOA possible by
adding external transistors
•
Input voltage 40V max
•
Output voltage adjustable from 2V to 37V
•
Can be used as either a linear or a switching
regulator.
The LM723/LM723C is also useful in a wide range
of other applications such as a shunt regulator, a
current regulator or a temperature controller.
The LM723C is identical to the LM 723 except
that the LM723C has its performance guaranteed
over a O°C to 70°C temperature range, instead of
_55°C to +125°C.

LH0001*/LH0001C, low power operational amplifier
general description
The LHOOOl /LHOOOl C is a general purpose operational amplifier designed for extremely low
quiescent power. Typical NO-load dissipation at
25°C is 2 milliwatts at Vs = ±l5 volts, and 0.5
milliwatts at Vs = ±5 volts. Even with this low
power dissipation, the LHOOOl /LHOOOl C will
deliver ±lO volts into a 2K load with ±l5 volt
supplies, and typical short circuit currents of 20 to
30 milliamps. Additional features are:
•
Operation fro'm ±5V to ±20V
•
Very low offset voltage: typically 200 J.l.V
at 25°C, 600 J.l.V at -55°C to 125°C
•
g
n
Very low input offset current: typically 3 nA
at 25°C, 6 nA at _55°C
•
Low noise: typically 3 J.l.V rms
•
Frequency compensation with 2 small capacitors
•
Output may be clamped at any desired level
•
Output is continuously short circuit proof
The LHOOOl /LHOOOl C is ideally suited for space
borne applications or where battery operated equipment requires extremely low power dissipation.

at least 5 volts more negative than the positive supply
(Pin 9). Pin 7 may be connected to the negative supply,
howe\ler the standby current will be increased. A resistor
may be inserted in series with Pin 7 up to a maximum of
100 kG per volt between Pin 3 and Pin 9.

»
• Full operating range: -55°C to +125°C
The LH0005/LH0005A is a hybrid integrated circuit operational amplifier employing thick film
resistors and discrete silicon semiconductors in its
design_ The select matching of the input pairs of
transistors results in low input bias currents and a
very low input offset current, both of which exhibit excellent temperature tracking. In addition,
the device features:
• Good high frequency response: unity gain at
30MHz
With no external roll-off network, the amplifier is
stable with a feedback ratio of 10 or greater. By
adding a 200 pF capacitor between pins 9 and 10,
and a 200 ohm resistor in series with a 75 pF
capacitor from pin 4 to ground, the amplifier is
stable to unity gain. The unity gain loop phase
margin with the above compensation is typically
70 degrees. With a gain of 10 and no compensation
the loop phase margin is typically 50 degrees.
• Very high output current capability: ±50 mA
into a 100 ohm load
• Low standby power dissipation: typically
60 mW at ±12V
• High input resistance: typically 2M at 25°C

LH0005C* operational amplifier
general description
The LH0005C is 8 hybrid integrated circuit operational amplifier employing thick film resistors
and discrete silicon semiconductors in its design.
The select matching of the input pairs of transistors results in low input bias currents and a very
low input offset current both of which exhibit
excellent temperature tracking. In addition, the
dev ice featu res:
• Very high output current capability: ±40 mA
into a 100 ohm load
• Low standby power dissipation: typically
60 mWat±12V
• High input resistance: typically 2M at 25°C
• Operating range: 0° to 70° C
• Good high frequency response: unity gain at
30 MHz
With .no external roll·off network, the amplifier is
stable with a feedback ratio of 10 or greater. By
adding a 200 pF capacitor between pins 9 and 10,
and a 200 ohm resistor in series with a 75 pF
capacitor from pin 4 to ground, the amplifier is
stable to unity gain. The unity gain loop phase
margin with the above compensation is typically
70 degrees. With a gain of 10 and no compensation
the loop phase margin is typically 50 degrees.

general description

....I
The LH0023/LHOO23C and LH0043/LH0043C
are complete sample and hold circuits including
input buffer amplifier, FET output amplifier,
analog signal sampling gate, TTL compatible logic
circuitry and level shifting. They are designed to
operate from standard ±15V DC supplies, but
provision is made on the LH0023/LH0023C for
connection of a separate +5V logic supply in
minimum noise applications. The principal differ-'
ence between the LH0023/LH0023C and the
LH0043/LH0043C is a 10: 1 trade-off in performance on sample accuracy vs sample acquisition
time. Devices are pin compatible except that TTL
logic is inverted between the two types.

hold applications including data acquisition,
analog to digital conversion, synchronous demodulation, and automatic test setup. They offer
significant cost and size reduction over equivalent
module or disCrete designs. Each device is available
in a hermetic TO-8 package and are completely
specified over both full military and instrument
temperature ranges.
The LH0023 and LH0043 are specified for operation over the _55°C to +125°C military temperature range. The LH0023C and LH0043C are
specified for operation over the _25°C to +85°C
temperature range.
The LH0023/LHOO23C and LH0043/LH0043C
are ideally suited for a wide variety of sample and
features

1.0 Drift Error Minimization

...I
o
o
In order to minimize drift error. care in selection
of Cs and layout of the printed circuit board is
required. The capacitor should be of high quality
Teflon, polycarbonate, or polystyrene construc·
tion. Board cleanliness and layout are critical
particularly at elevated temperatures. See AN·63
for detailed recommendations. A guard conductor
connected to the output surrounding the storage
node (pin 1) will be helpful in meeting severe
environmental conditions which would otherwise
cause leakage across the printed circuit board.

total leakage current at pin 1 of the device, and
Cs is the value of the storage capacitor.
2.1 Capacitor Selection - LH0023
At room temperature leakage current for the
LH0023 is approximately 100 pA. A drift rate of
10 mV /sec would require a O.Ol/-1F capacitor.
For values of Cs up to 0.01 /-IF the acquisition
time is limited by the slew rate of the input buffer
amplifier, A 1, typically 0.5 V//-Is. Beyond this
point, current availability to charge Cs also enters
the picture. The acquisition time is given by:
will be stored on the capacitor, in much less time as
dictated by the slew rate and current capacity of
the input amplifier, but it will not be available at
the output). For larger values of storage capaci·
tance, the limitation is the current sinking capabil·
ity of the input ampl ifier, typically 10 mA. With
Cs =0.01 /-IF, the slew rate can be estimated by

dt = 0.01 '10-6 = 1 VI/-Is or a sleWing tIme for a
5 volt signal change of 5/-1s.
3.0 Offset Null
Provision is made to null both the LH0023 and
LH0043 by use of a 10k pot between pins 3 and 4.
Offset null should be accomplished in the sample
mode at one half the input voltage range for
minimum average error.
4.0 Switching Spike Minimization-LHOO43
A capacitive divider is formed by the storage
capacitor and the capacitance of the internal F ET
switch which causes a small error current to be
injected into the storage capacitor at the termina·
tion of the sample interval. This can be considered
a negative DC offset and nulled out as described in
(3.0), or the transient may be nulled by coupling
an equal but opposite signal to the storage
capacitor. This may be accomplished by connect·
ing a capacitor of about 30 pF (or a trimmer)
between the logic input (pin 6) and the storage
capacitor (pin 1). Note that this capacitor must be
chosen as care,fully as the storage capacitor itself
with respect to leakage. The LH0023 has switch
spike minimization circuitry built into the device.

2.2 Capacitor Selection-LH0043
At 25°C case temperature, the leakage current for
the LH0043G is approximately 10 pA, so a drift
rate of 5 mV/s would require a capacitor of
Cs = 10 • 10-12 /5 '10- 3 = 2000 pF or larger.
For values of Cs below about 5000 pF, the
acquisition time of the LH0043G will be limited
by the slew rate of the output amplifier (the
signal will be acquired, in the sense that the voltage

The 5V logic supply may be eliminated by
shorting pin 7 to pin 8 which connects a 10k
dropping resistor between the +15V and Vc.
Decoupling pin 8 to ground through 0.1 /-IF disc'
capacitor is recommended in order to minimize
transients in the output.
6.0 Heat Sinking
The LH0023 and LH0043G may be operated
without damage throughout the military tempera,
ture range of -55 to +125°C (-25 to +85°C for
the LH0023CG and LH0043CG) with no explicit
heat sink. however power dissipation will cause the
internal temperature to rise above ambient. A
simple clip·on heat sink such as Wakefield
#215-1.9 or equivalent will reduce the internal
temperature about 20°C thereby cutting the leak·
age current and drift rate by one fourth at max.
ambient. There is no internal electrical connection
to the case. so it may be mounted directly to a
grounded heat sink.
7.0 Theory of Operation-LH0023
The LH0023/LH0023C is comprised of input
buffer amplifier, A 1, analog switches, Sl and 52, a

applications information (con't)
TTL to M05 level translator, and output buffer
amplifier, A2. In the "sample" mode, the logic
input is raised to logic "1" (V6 ~ 2.0V) which
closes 51 and opens 52. 5torage capacitor, Cs , is
charged to the input voltage through 51 and the
output slews to the input voltage. In the "hold"
mode, the logic input is lowered to logic "a"
(V 6 ~ 0.8V) opening 51 and closing 52. Cs
retains the sample voltage which is applied to the
output via A2. 5ince 51 is open, the input signal
is overridden, and leakage across the M05 switch is
therefore minimized. With 51 open, drift is primarily determined by input bias current of A2,
typically 100 pA at 25° C.
7.1 Theory of Operation-LH0043
The LH0043/LH0043C is comprised of input
buffer amplifier A 1, FET switch 51 operated by a
TTL compatible level translator, and output buffer
amplifier A2. To enter the "sample" mode, the
logic input is taken to the TTL logic "0" state
(V 6 = 0.8V) which commands the switch 51

the "hold" mode (V 6 = 2.0V), 51 is opened
isolating the storage capacitor from the input and
leaving it charged to a voltage equal to the last
analog input voltage before entering the hold
mode. The storage capacitor voltage is brought to
the output by low leakage amplifier A2.

1. Layout Considerations
2·46
-1, C3 may requ ire adjustment in order to per·
fectly cancel the input capacitance of the device.
When operating the LH0024/LH0024C at a gain
of +1, the value of R 1 should be at least lK ohm.
The LH0024/LH0024C,like most high speed cir·
cuitry, is sensitive to layout and stray capacitance.
Power supplies should be by·passed as near the
device as is practicable with at least .01 /-IF disc
type capacitors. Compensating capacitors should
also be placed as close to device as possible.
The case of the LHOQ24 'is electrically isolated from
the circuit; hence, it may be advantageous to drive
the case in order to minimize stray capacitances.
2. Compensation Recommendations
3. Heat Sinking
Compensation schemes recommended in Table 1
work well under typical conditions.. However. poor
layout and long lead lengths can degrade the per·
formance of the LH0024 or cause the device to
oscillate. Slight adjustments in the values for
Cl, C2; and C3 may be necessary for a given
layout. In particular, when operating at a gain of
The LH0024/LH0024C is specified for operation
without the use of an explicit heat sink. However,
internal power dissipation does cause a significant
temperature rise. Improved offset voltage drift
can be obtained by limiting the temperature rise
with a clip·on heat sink such as the Thermalloy
22288 or equivalent.

input impedance differential operational amplifier
suitable for diverse application in fast signal handl·
ing. The high allowable differential input voltage,
ease of output clamping, and high output drive
capability particularly suit it for comparator appli·
cations. It may be used in applications normally
reserved for video amplifiers allowing the use of
operational gain setting and frequency response
shaping into the megahertz region.

applications information
Power Supply Decoupling
The LH0032/LH0032C like most high speed cir·
cuits is sensitive to layout and stray capacitance.
Power supplies should be by·passed as near to
Pins 10 and 12 as practicable with low inductance
capacitors such as O.01IlF disc ceramics. Compen·
sation components should also be located close to
the appropriate pins to minim ize stray reactances.
Input Capacitance
The input capacitance to the LH0032/LH0032C is
typically 5 pF and thus may form a significant
time constant with high value resistors. For opti·
mum performance, the input capacitance to the
inverting input should be compensated by a small
capacitor across the feedback resistor. The value
is strongly dependent on layout and closed loop
gain, but will typically be in the neighborhood of
several picofarads.
In the non·inverting configuration, it may be
advantageous to bootstrap the case and/or a guard
conductor to the inverting input. This serves both
to divert leakage currents away from the non·
inverting input and to reduce the effective input
capacitance. A unity gain follower so treated will
have an input capacitance under a picofarad.
Heat Sinking
While the LH0032/LH0032C is specified for opera·
tion without any explicit head sink, internal power
dissipation does cause a significant temperature
rise. Improved bias current performance can thus
be obtained by limiting this temperature rise with
a small head sink such as the Thermalloy No. 2241
or equivalent. The case of the device has no inter·
nal connection, so it may be electrically connected
to the sink if this is advantageous. Be aware, how·
ever, that this will affect the stray capacitances
to all pins and may thus require adjustment of
circuit compensation values.

Recommended Layout Precautions:
RF/video
printed circuit board layout rules should be followed when using the LH0033 and LH0063 since
they will provide power gain to frequencies over
100 MHz. Ground planes are recommended and
power supplies should be decoupled at each device
with low inductance O.lJ.!F disc capacitors. In
addition, ground plane shielding may be extended
to the metal case of the device since it is
electrically isolated from internal circuitry. Alternatively the case should be connected to the
output to minimize input capacitance.
Offset Voltage Adjustment Both the LHOO33's
and LH0063's offset voltages have been actively
trimmed by laser to meet guaranteed specifications
when the offset preset pin is shorted to the offset
adjust pin. This pre-calibration allows the devices
to be used in most DC or AC applications without
individually offset nulling each device. If offset
null is desirable, it is simply obtained by leaving
the offset preset pin open and connecting a trim
pot of lOOn for the LH0033 or 1 kn for the
LH0063 between the offset adjust pin and Vas illustrated in Figures 1 and 2.

Operation from Si ngle or Asymmetrical Power
Supplies: Both device types may be readily used
in applications where symmetrical supplies are
unavailable or not desirable. A typical application
might be an interface to a MOS shift register
where V+ : +5V and V- : -12V. In this case,
an apparent output offset occurs due to the de·
vice's voltage gain of less than unity. This additional
output offset error may be predicted by:
w
as illustrated in Figures 3 and 4. Resistor values

where:

V+ : Positive supply voltage
V : Negative supply voltage
For the above example, AVo would be -35 mY:
This may be adjusted to zero as described in
Section 2. For AC coupled applications, no addi·
tional offset occurs if the DC input is properly
biased as illustrated in the "typical applications"
section.
Short Circuit Protection: In order to optimize
transient response and output swing, output current limit has been omitted from the LH0033
and LH0063. Short circuit protection may be
added by inserting appropriate value resistors
between V+ and Vc + pins and V- aQd Vc - pins

The inclusion of limiting resistors in the collectors
of the output transistors reduces output voltage
swing. Decoupling Vc + and Vc - pins with ca·
pacitors to ground will retain full output swing
for transient pUlses. Alternate active current limit
techniques that retain full DC output swing are
shown in Figures 5, 6 and 7. In Figures 5 and 6,
the current sources are saturated during normal
operation thus apply full supply voltage to the
Vc pins. Under fault conditions, the voltage de·
creases as required by the overload. For Figure 5:

Capacitive Loading: Both the LH0033 and LH0063
are designed to drive capacitive loads such as coaxial cables in excess of several thousand picofarads
without susceptibility to oscillation_ However,
peak current resulting from (C X d v Id t ) should be
limited below absolute maximum peak current
ratings for the devices.
Thus for the LH0033:

and for the LH 0063:

Peak current limiting may be accomplished by
controlling input large signal rise time, inserting
20 to 100s/. resistors between V+ and Vc + pins
and V- and V c pins, using active current limit
as described in Section 4, Figures 5, 6 and 7, or
inserting a small value resistor in series with the
output.

Hardware: In order to utilize the full drive
capabilities of both devices, each should be
mounted with a heat sink particularly for extended temperature operation. The cases of both
are isolated from the ci rcuit and may be connected to system chassis. Heat sinks are commercially available at low cost; the following or
their equivalents are recommended:

resistor of 47Q should be used between the op
amp output and the input of LH0033. The wide
bandwidths and high slew rates of the LH0033

general description
G')
The LH0036G/LH0036CG is a true micro power
instrumentation amplifier designed for precision
differential signal processing. Extremely high accu·
racy can be obtained due to the 300 Mn input
impedance and excellent 100 dB common mode
rejection ratio. It is packaged in a hermetic TO·8
package. Gain is programmable with one external
resistor from 1 to 1000. Power supply operating
range is between ±lV and ±18V. Input bias current
and output bandwidth are both externally ad·
justable or can be set -by internally set values.
The LH0036G is specified for operation over the
-55°C to +125°C temperature range and the
LH0036CG is specified for operation over the
-25°C to +85°C temperature range.

FIGURE 1. Simplified LH0036
The LH0036 is a 2 stage amplifier with a high
input impedance gain stage comprised of A, and
A2 and a differential to single·ended unity gain
stage, A3 . Operational amplifier, A" receives
differential input signal, e" and amplifies it by a
factor equal to (R1 + RG)/R G.
A, also receives input e2 via A2 and R2. e2 is seen
as an inverting signal with a gain of R1/RG' A,
also receives the common mode signal eCM and
processes it with a gain of +1.

Use of Pin 9, CMRR Preset
Pin 9 should be grounded for nominal operation.
An internal factory trimmed resistor, R6, will
yield a CM R R in excess of 80 dB (for AvcL = 100).
Should a higher CMRR be desired, pin 9 should
be left open and the procedure, in this section
followed.

The closed loop gain may be set to any value from

re·arranged in more convenient form may be used

FIGURE 5. CMRR Adjustment Circuit
The circuits of Figure 4 and 5 may be combined
as shown in Figure 6 to accomplish both Vas
and CMRR null. However, the Vas and CMRR
adjustment are interactive and several iterations
are required. The procedure for null should start
'with the inputs grounded.

After adjusting R 1 for best dc CM R R as before,
R2 should be adjusted for minimum peak-to·peak
voltage at the output while applying an ac
common mode signal of the maximum amplitude
and frequency of interest.
.INPUT BIAS CURRENT CONTROL
Under nominal operating conditions (pin 3 grounded), the LH0036 requires input currents of 40 nA.
The input. current may be reduced by inserting a
resistor (R B) between 3 and ground or, alternatively, between 3 and V-. For RB returned to
ground, the input bias current may be predicted
by:

R2 is adjusted for Vas null. An input of +10V
is then applied and Rl is adjusted for CMRR null.
The procedure is then repeated until the optimum
is achieved.
A circuit which overcomes adjustment interaction
is shown in Figure 7. In this case, R2 is adjusted
first for output null of the LH0036. R 1 is then
adjusted for output null with +10V input. It is
always a good idea to check CMRR null with a
-10V input. The optimum null achievable will
yield the highest CM R R over the amplifiers com·
mon mode range.

Designed for use with various sensors, the LH0045/
LH0045C will interface with thermocouples, strain
gauges, or thermistors. The use of the power
supply leads as the signal output eliminates two
or three extra wires in remote signal applications.
Also, current output minimizes susceptibility to
voltage noise spikes and eliminates line drop
problems.
The LH0045/LH0045C is intended to fulfill a wide
variety of process control, instrumentation, and
data acquisition applications. The LH0045 is
guaranteed over the temperature range of-55°C to

CIRCUIT DESCRIPTION AND OPERATION
A simplified schematic of the LH0045/LH0045C
is shown in Figure 1. Differential amplifier, A2
converts very low level signals to an output current
via transistor 01. Reference voltage diode D 1 is
used to supply voltage for operation of A2 and
to bias an external bridge. Current source 11
minimizes fluctuation in the bridge reference
voltage due to changes in Vs.
In normal operation, the LH0045/LH0045C is
used in conjunction with an external bridge
comprised of RBI through R B4 . The bridge
resistors in conjunction with bridge return resistor,
R5, bias A2 in its linear region and sense the input
signal; e.g. RB4 might be a strain sensitive resistor
in a strain gauge bridge. RT is adjusted to purposely
unbalance the bridge for 4.0 rnA output (null)
for zero signal input. This is accomplished by
forcing 2.5j.LA more through RB3 than R B4 .
The 2.5j.LA imbalance causes a voltage rise of
(2.5j.LA) x (lOOn) or 250j.LV at the top of R B3 .
Terminal L2 may be viewed as the output of an
op amp whose closed loop gain is approximately
RF/RB3 = 1600.
The 250j.LV rise at the top of RB3 causes a
voltage drop of (1600) x (250j.LV) or -0.4V across
R9. An output current, Is, equal to O.4V IR9 or
4.0 rnA is thus established in 01. If RB4 is now
decreased by 1.0n (due to application of a strain
force), a -1.0 mV change in input voltage will
result. This causes L2 to drop to -2.0V. The
output current would then be 2.0V/l00nor 20 rnA
(Full Scale). If RB3 is a resistor of the same
material as RB4 but not subjected to the strain,
temperature drift effects will be equal in the two
legs and will cancel.
In actual practice the loading effects of RB2 on
the gain (span) and RF on output current must be
taken into account.

THERMAL CONSIDERATIONS
The power output transistor of the LH0045 is
thermally isolated from the signal amplifier, A 2 .
Nevertheless, a change in the power dissipation
will cause a change in the temperature of the
package and thus may cause amplifier drift. These
temperature excursions may be minimized by
careful heat sinking to hold the case temperature
equal to the ambient. With the TO·8 (G) package
this is best accomplished by a clip·on heat sink
such as the Thermalloy #2240A or the Wakefield
#215-CB. The 8 lead TO-3 is particularly convenient
for heat sinking, in that it may be bolted directly
to many commercial aluminum heat sink extrusions, or to the chassis. In both packages the case
is electrically isolated from the circuit.
In addition, the power change can be minimized
by operating the device from relatively high supply
voltages in series with a relatively high load resistance. When the signal forces the supply current
higher, the voltage across the device will be
reduced and the internal power dissipation kept
nearly equal to the low current, high voltage
condition.
For example, take the case of a 4.0 mA to 20 mA
transmitter with a 24V supply and a lOOn load
resistance. The power at 4.0 mA is (23.6V) x (4.0
mAl = 94.4 mW while at full scale the power is
(22V) x (20 mAl = 440 mW. The net change in
power is 345 mW. This change in power will cause
a change in temperature and thus a change in
offset voltage of A2 .
If the optimum load resistance of 800n (from
Figure 2) is used, the power at null is [24V (4.0 mAl x (800n)] (4.0 mAl = 83 mW. The
power at full scale is [24V - (20 mAl x (800n))
(20 mAl = 160 mW. The net change is 77 mW.
This change is significantly less than without the
resistor.
If the supply voltage is increased to 48V and the
load resistance chosen to be the optimum value
from Figure 2 (1.95k), then the power at null is
[48V - (4.0 mAl x (1.95k)] (4.0 mAl = 160.8
U'I
........
mW and the power at full scale is [48 - (20) x
(1.95k)] (20 mAl = 180 mW for a net change of
19.2 mW.
r:::t
o
o
Note that the optimized load resistance is actually
the sum of the line resistance, receiver resistances
and added external load resistance. However, in
many applications the line resistance and receiver
resistances are negligible compared to the added
external load resistance and thus may be omitted
in calculations.

AUXILIARY PINS
The LH0045 has several auxiliary pins designed to
provide the user with enhanced flexibility and
performance. The following is a discussion of possible uses for these pins.
Programmable VREF - Pins 5 and 6 (LH0045G
Only)
The LH0045G provides pins 5 and 6 to allow the
user to program the value of the reference voltage.
The factory trimmed 10V value is obtained by
leaving 5 and 6 open. A short between 5 and 6
will program the reference to a. nominal 5.1V
(equivalent to the fixed value used in the
LH0045K).
A resistor or pot may be placed between pin 5
and common (pin 3) to obtain reference voltages
between 10V and 30V or between pin 5 and pin 7
for reference voltages below 10V. Increased reference voltage might be useful to extend the
positive common mode range or to accommodate
transducers requiring higher supply voltage. A plot
of resistance between pin 5 and pin 3 versus
V REF is given in the typical electrical characteristics
section. V REF may be adjusted about its nominal
value by arranging a pot from V REF to common
and feeding a resistor from the wiper into pin 5
so that it may either inject or extract current.
Lastly, pin 5 may be used as a nominal 1.7V
reference point, if care is taken not to unduly
load it with either dc current or capacitance.
Obviously, higher supply voltages must be used
to obtain the higher reference values. The minimum
supply voltage to reference voltage differential is
about 4.0V.

An applications resistor is provided in the LH0045
with a nominal value of 1.0 kn. The primary
application for the resistor is to maintain the
minimum common mode input voltage (1.0V)
required by the signal amplifier, A 2 . A typical
input application might utilize a strain gauge or
thermistor bridge where the resistance of the
sensor is lOOn. Since only 1.0 mA may be drawn
from V REF, the 1.0 kn bridge return resistor is
used to bias A2 in its linear region as shown in
Figure 3.

DESIGN EXAMPLE
Over Compensation - Pin 8 (LH0045G),
Pin 6 (LH0045K)
Over compensation of the signal amplifier, A2 may
be desirable in dc applications where the noise·
bandwidth must be minimized. A capacitor should
be placed between pin 8 (pin 6 on the LH0045K)
and pin 3, common.
There are numerous circuit configurations that
may be utilized with the LH0045. The following
is intended as a general design example which
may be extended to specific cases.

Pins 9 and 12 have no internal connection what·
ever and thus need not be used. In some critical
low current applications there may be an advantage
to running a guard conductor between the inputs
and the adjacent pins to intercept stray leakage
currents. Pins 9 and 12 may be connected to this
guard to simplify the PC board layout and allow
the guard to continue under the device. (See AN·63
for further discussion of guarding techniques.)

NULL AND SPAN ADJUSTMENTS
Most applications of the LH0045 will require
potentiometers to trim the initial tolerances of the
sensor, the external resistors and the LH 0045 itself.
The preferred adjustment procedure is to stimulate
the sensor, alternating between two known values,
such as zero and full scale. The span and null are
adjusted by monitoring the output current on a
chart recorder, meter, or oscilloscope. A full scale
stimulus is applied to the sensor and the span
potentiometer adjusted for the desired full scale.
Then, to adjust the null, apply a zero percent
signal to the sensor and adjust the null potentio·
meter for the desired zero percent current
indication.
If it is impractical to cycle t"'e sensor during the
calibration procedure, the signal may be simulated
electrically with two cautions: 1) the calibration

Selection of RF
Input bias current to the LH0045C is guaranteed
less than 10 nA. Furthermore, the change in IB
over the temperature range of interest is typically
under 1.0 nA. If 12 SPAN is selected to be 1.01lA
(1000 A IB) errors due to AlB/A T will be less
than 0.1%. For SPAN ~ 16 mAo

Selection of RBl and RB2
The minimum input common mode voltage, V MIN
required at the pin 10 input of A2 is 1.0V.
Furthermore, the maximum open loop supply
current (IS0L) drawn by the LH0045 is 3.0 mAo
That leaves IMIN = 4.0 mA - 3.0 mA = 1.0 mA
left to bias the bridge at null. Hence:
1.0V
1.0kQ
This current must be provided by Ros from
V REF ; hence:
V REF - V MIN
Ros=----12 NULL
The nominal value for V REF is 5.1V, therefore
the nominal value for Ros is:
5.1V - 1.0V
1.0 mA
or
0.B75pA
And,
Ros = 4.6 MQ
1.0V
V REF -1.0V
RS2
1.0V
= 1.0k (5.1 -1.0)
Alternatively, an LM 113, 1.22V reference diode,
or an op amp such as the LM 1OB may be used to
bias the signal amplifier, A2 as shown in Figure 5.
These techniques have the advantage of lowering
the impedance seen at pin 10.
It should be noted however, that the variation of
V REF may be as high as 5.9V or as low as 4.3V.
Furthermore, the tolerances of R9 (100Q), R s1 .
Rs2 , and the input Vos of A2 would predict values
for Ros as low as 3.9BM and as high as 5.43M. The
implication is that in the specific case, Ros should
be implemented with a pot, of appropriate value,
in order to accommodate the tolerances of V REF,
R9, Vos, RS1 , RS2i etc.

External Resistor Values
1. Select IF ULL SCAL.E = IN ULL + ISPAN for the
desired application. (I NULL is frequently
4.0 mA and IFULL SCALE is frequently
20mA.)
There are several factors which could cause a
change in V REF. First, as the ambient temperature
changes, a V REF drift of ±0:2 mVfC might
be expected. Secondly, supply voltage variations
could cause a 0.5 mV!V change in V REF . Lastly,
self·heating due to power dissipation variations
can cause drift of the reference.
An overall expression for change in V REF is:

Several steps may be taken to minimize the
bracketed terms in the equation above. For
example, operating the LH0045G with a heat·sink
reduces the thermal resistance from JA = 83°C/W
to JC = 60°C/W. For the LH0045K (TO·3)
JA = 40°C/W may be reduced to JC = 25°C/W
by using a heat sink. The L).P DISS term may be
significantly reduced using the power minimiza·
tion technique described under "Thermal Con·
siderations." For the design example, L).P DISS is
reduced from 384 mW to 77 ,mW (R L = 800£2.)
Evaluating the LH0045G with a heat·sink and
RL = 800£2 yields.

error might be expected in output currents due to
Ll.V REF effects.
The temperature coefficient of R9 (TCR) will
produce errors in the output current. Changes in

by ambient temperature changes.

Error Due to Vos Drift
Change in ambient temperature
One of the primary causes of error in Is is caused
by Vos drift. Drift may be induced either by
self heating of the device or ambient temperature
changes. The input offset voltage drift, Ll. Vos / Ll.T,
is nominally 3.3/1V/oC per millivolt of initial offset.
An expression for the total temperature dependent
drift is:
Ll.R9
Ll.T
TCR of R9
Using the LH0045G design example, Ll.R9/Ll.T =
0.03%/oC, hence a 3.2% worst case error in output
current might be expected for operation without
a heat sink over the temperature range.
Heat sinking the device and using RL = BOOn,
reduces Ll.ls/lsPAN to 2.3%. Comparable error for
the LH0045K would also be about 2.3%.
Where:
8

The error analysis indicates that the internal
current set resistor, R9 is inadequate to satisfy
high accuracy design criterion. In these instances,
an external lOOn resistor should be substituted
for R9.
Change in ambient temperature
The bracketed term may be minimized by
heat sinking and using the power minimization technique described under "Thermal
Considerations." For the LH0045G design
example, Ll.Vos = 0.352 mV under ambient
conditions and 0.263 mV using a heat-sink
and RL = BOOn. Comparable Vos for the
LH0045K would be 0.254 mV.

Obviously, the TCR of the resistor should be low.
Metal film or wire-wound resistors are the best
choice offering TCR's less than 10 ppmtC versus
50 ppmtC typical drift for R9.
External Causes of Error
The components external to the LH0045 are also
critical in determining errors. Specifically, the
composition of resistors RS1 , Ros, R F , R, etc.
in the design example will influence both drift
and long term stability.
In particular, resistors and potentiometers of wire
wound construction are recommended. Also, metalfilm resistors with low TCR (::; 10 ppmtC) may
be used for fixed resistor applications.

Error Analysis Summary
SOCKETS AND HEAT SINKS
The overall errors attributable to the LH0045
may be minimized using heat sinking, and utilization of an external load resistor. Although RL
reduces the compliance of the circuit, its use is
generally advisable in precision applications. External components should be selected for low
TCR and long-term stability.

applications information
SOURCE IMPEDANCE COMPENSATION
The gain accuracy (linearity) of the LH00531
LH0053C is set by two internal precision-resistors.
Circuit applications in which the source impedance
is non·zero will result in a closed loop gain error,
e.g. if Rs ~ 10Q, a gain error of 0.1 % results.
Figure 1 and 2 show methods for accommodating
non·zero source impedance.
DRIFT ERROR MINIMIZATION
In order to minimize drift error, care in selection
C F and layout of the printed circuit board is
required. The capacitor should be of high quality
teflon, polycarbonate or polystyrene construction.
Board layout and clean lines are critical particularly
at elevated temperature.
A ground guard (shield) surrounding pin 5 will
minimize leakage currents to and from the summing
junction, arising from extraneous signals. See
AN·63 for detailed recommendations.
CAPACITOR SELECTION
The size of the capacitor is determined by the
required drift rate usually at the expense of
acquisition time.
2·84
The drift is dictated by leakage current at pin 5
and is given by:
IL
dv
dt
CF
Where I L is the leakage current at pin 5 and C F
is the value of the capacitance. The room tempera,
ture leakage of the LH0053 is typical 6.0 pA, and
a 1000 pF capacitor will yield a drift rate of
6.0 mV per second.
For values of C F below 1000 pF acquisition for

GATE INPUT CONSIDERATIONS
Unused Switch, 02
5.0V TTL Applications
In applications when switch Q2 is not used the
logic input (pin 7) should be returned to +5.0V
(or +15V for HTL applications) through a 10kn
resistor. Analog Input, preset (pin 8) should be
grounded.
The LH0053 Gate inputs Gate 1 (pin 6) and Gate
2 (pin 7) will interface directly with 5.0V TTL.
However, TTL gates typically pull up to 2.5V in
the logic "1" state. It is therefore advisable to
use a tOk pull·up resistor between the 5.0V, Vee,
and the output of the gate as shown in Figure 3.

CMOS Applications
The LH0053 gate inputs may be interfaced directly
with 74C, CMOS operating off of Vee's from
5.0V to 15V. However transient currents of
several milliamps can flow on the rising and
falling edges of the input signal. It is, therefore,
advisable to parallel the outputs of two 54C/74C
gates as shown in Figure 4.
It should be noted that leakage at pin 5 in the
hold mode will be increased by a factor of 2 to 3
when operating into 15V logic levels.
FIGURE 4. CMOS Logic Compatibility
HEAT SINKING
The LH0053 may be operated over the military
temperature range, -55°C to +125°C, without
incurring damage to the device. However, a clip
on heat sink such as the Wakefield 215 Series or
Thermolloy 2240 will reduce the internal. tempera,
ture rise by about 20°C. The result is a two-fold
improvement in drift rate at temperature.

applications information (con't)
Since the case of the device is electrically isolated
from the circuit, the LH0053 may be mounted
directly to a grounded heat sink.
capacitors in order to prevent oscillation. Should
this procedure prove inadequate, the disc capacitors
should be parallel with 4.71lF solid tantalum
electrolytic capacitors.
POWER SUPPLY DECOUPLING
DC OFFSET ADJUST
Amplifiers Aland A2 within the LH0053 are very
wide band devices and are sensitive to power supply
inductance. It is advisable to bypass V+ (pin 12)
and V- (pin 10) to ground with O.lIlF disc
Output offset error may be adjusted to zero using
the circuit shown in Figure 5. Offset null should
be accomplished in the sample mode (Vs ~ 0.5V)
and analog input (pin 4) equal to zero volts.

LH0062/LH0062C high speed FET op amp
::I:
general description
o
....I
The LH0062/LH0062C is a precision, high speed
FET input operational amplifier with more than
an order of magnitude improvement in slew rate
and bandwidth over conventional FET IC op
amps. I n addition it features very closely matched
input characteristics, very high input impedance,
and ultra low input currents with no compromise
in noise, common mode rejection ratio or open
loop gain. The device has internal unity gain frequency compensation, thus assuring stability in all
normal applications. This considerably simplifies
its application, since no external components are
necessary for operation. However, unlike most
internally compensated amplifiers, external frequency compensation may be added for optimum
performance. For inverting applications, feedforward compensation will boost the slew rate to
over 120 V /J.J.s and almost double the bandwidth.
(See LB-2, LB-14, and LB-17 for discussions of
the application of feed-forward techniques). Over·
compensation can be used with the amplifier for
greater stability when maximum bandwidth is not
needed. Further, a single capacitor can be added to
reduce the 0.1% settling time to under 1 J.J.S. In
addition it is free of latch-up and may be simply
offset nulled with negligible effect on offset drift
or CMRR.
The LH0062 is designed for applications requiring
wide bandwidth, high slew rate and fast settling
time while at the same time demanding the high
input impedance and low input currents characteristic of FET inputs. Thus it is particularly suited
for such applications as video amplifiers, sample/
hold circuits, high speed integrators, and buffers
for A/D conversion and multiplex system. The
LH0062 is specified for the full military temperature range of _55° to +125°C while the LH0062C
is specified to operate over a _25°C to +85°C
temperature range.

LH101 operational amplifier
general description
The LH101 is a ge;leral-purpose operational amplifier which is internally compensated for unity-gain
feedback. The device combines a LM101 operational amplifier and the 30 pF compensation capacitor
in a single package. As such, it is a direct, plug-in
replacement for both the LM101 and the LM709
in the majority of applications. Features of the amplifier include:
•
Operation guaranteed for supply voltages from
±5V to ±20V
•
Low current drain - even with the output saturated
•
No latch-up when common-mode range is exceeded
•
Continuous short-circuit protection
•
Input transistors protected from excessive input
voltage.
The LH101 is available in either an a-lead, lowprofile TO-5 header or a 1/4" x 1/4" metal flat
package.

Note 1: The maximum junction temperature of the LH2110 is 150°C. while that of the LH2210 is 100°C and the LH2310 is
S5°C. For operating at elevated temperatures, devices in the flat package, the derating is based on a thermal resistance of
185°C/W when mounted on a 1/16-inch-thick epoxy glass board with O.03-inch-wide, 2-ounce copper conductors. The
thermal resistance of the dual-in-Iine package is 100°C/W, junction to ambient.
Note 2: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
Note 3: Continuous short circuit is allowed for case temperatures to 12So C and ambient temperatures to 70o e. It is necessary
to insert a resistor greater than 2 kn in series with the input when the amplifier is driven from low impedance sources to prevent damage when the output is shorted.
Note 4: These specifications apply for ±5V ~ Vs ~ ±18V and -55°C $. TA ~ 125°C. unless otherwise specified. With the
LM210. however, all temperature specifications are limited to -25°C ~ TA ~ 85°C and for the LH2310. all temperature
specifications are limited to O°C ~ TA ~ 70°C.
Note 5: Increased output swing under load can be obtained by connecting an external resistor between the booster and Vterminals.

LM101 operational amplifier
general description
• No latch-up when common mode range is exceeded
The LM101 is a general-purpose operational amplifier built on a single silicon chip_ The resulting close
match and tight thermal coupling gives low offsets
and temperature drift as well as fast recovery from
thermal transients. In addition, the device features:
•
• Same pin configuration as the LM709.
The unity-gain compensation specified makes the
circuit stable for all feedback configurations, even
with capacitive loads. However, it is possible to
optimize compensation for best high frequency performallce at any gain. As a comparator, the output
can be clamped at any desired level to make it
compatible with logic circuits. Further, the low
power dissipation permits high-voltage operation
and simplifies packaging in full-temperature-range
systems.
Frequency compensation with a single 30 pF
capacitor
• Operation from ±5V to ±20V
•
Low current drain: 1.8 mA at ±20V
• Continuous short-circuit protection
• Operation as a comparator with differential inputs as high as ±30V

Note 1: For operating at elevated temperatures, the device must be derated based on a
e
1000 maximum junction temperature and a thermal resistance of 1 SOoC/W junction to
ambient or 4SoCIW junction to case for the metal-can package. For the flat package, the
derating is based on a thermal resistance of 18SoC/W when mounted on a 1/16·inch-thick,
epoxy-glass board with ten, O.03·inch·wide, 2-ounce copper conductors (see curve).
Note 2: For supply voltages less than ±15V, the absolute maximum input voltage is equal
to the supply voltage.
Note 3: Continuous short circuit is allowed for case temperatures to 70°C and ambient
temperatures to 55°C.
Note 4: These specifications apply for O°C ~ T A ~ 70°C, ±5V. ~ Vs ~ ±20V and Cl

LM101A/LM201A operational amplifier
general description
.
capacitor. It has advantages over internally compensated ampl ifiers in that the frequency compensation can be tailored to the particular application.
For example, in low frequency circuits it can be
overcompensated for increased stabi lity margin. Or
the compensation can be optimized to give more
than a factor of ten improvement in high frequency performance for most applications.
The LM101A and LM201A are general purpose
operational amplifiers which feature improved performance over industry standards like the LM10l
and the 709. Advanced processing techniques
make possible an order of magnitude reduction in
input currents, and a redesign of the biasing circuitry reduces the temperature drift of input current. Improved specifications include:
• Offset voltage 3 mV maximum over temperature
• Input current 100 nA maximum over temperature
• Offset current 20 nA maximum over temperature
• Guaranteed drift characteristics
The LM 101 A series offers the features of the
LM101, which makes its application nearly foolproof. In addition, the device provides better
accuracy and lower noise in high impedance circuitry. The low input currents also make it particularly well suited for long interval integrators or
timers, sample and hold circuits and low frequency
waveform generators. Further, replacing circuits
where matched transistor pairs buffer the inputs of
conventional Ie op amps, it can give lower offset
voltage and drift at a lower cost.
• Offsets guaranteed over entire common mode
and supply voltage ranges
• Slew rate of 10V/p.s as a summing amplifier
This amplifier offers many features which make its
application nearly foolproof: overload protection
on the input and output, no latch-up when the
common mode range is exceeded, freedom from
oscillations and compensation with a single 30 pF
The LM201A is identical to the LM101A, except
that the LM201A has its performance guaranteed
over a _25°C to 85°C temperature range, instead
of _55°C to 125°C.

Note1: The maximum junction temperature of the LM101A is 150°C, while that of the LM201A is lOOoe. For operating at
elevated temperatures, devices in the TO·5 package must be derated based on a thermal resistance of 150°C/W, junction to
ambient, or 45°C/W, junction to case. For the flat package, the derating is based on a thermal resistance of 185°C/W when
mounted on a 1/16-inch-thick epoxy glass board with ten, O.03-inch-wide, 2-ounce copper conductors. The thermal resistance
of the dual-in-line apckage is 100°C/W, junction to ambient.
Note 2: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
Note 3: Continuous short circuit is allowed for case temperatures to +125°C and ambient temperatures to +75°C.
Note 4: These specifications apply for ±5V:S VS:S ±20V and -55°C:S TA:S 125°C, unless otherwise specified. With the
LM201A, however, aU temperature specifications are limited to -25°C :S TA S 85°C.

Protecting Against Gross
Fault Conditions
Although the LM101A is designed for trouble free operation, experience has
indicated that it is wise to observe certain precautions given below to protect the
devices from abnormal operating conditions. It might be pOinted out that the
advice given here is applicable to practically any IC op amp, although the exact
reason why may differ with different devices.
When driving either input from a low-impedance source, a limiting resistor should
be placed in series with the input lead to limit the peak instantaneous output
current of the source to something less than 100 rnA. This is especially important
when the inputs go outside a piece of equipment where they could accidentally be
connected to high voltage sources. Large capacitors on the input (greater than
0.1 JJF) should be treated as a low source impedance and isolated with a resistor.
Low impedance sources do not cause a problem unless their output voltage exceeds the supply voltage. However, the supplies go to zero when they are turned
off, so the isolation is usually needed.
Compensating For Stray Input
Capacitances Or Largo Feedback
Resistor
The output Circuitry is protected against damage from shorts to ground. However.
when the amplifier output is connected to a test point, it should be isolated by
a limiting resistor, as test points'frequently get shorted to bad places. Further,
when the amplifier drives a load external to the equipment, it is also advisable
to use some sort of limiting resistance to preclude mishaps.
Precautions should be taken to insure that the power supplies for the integrated
circuit never become reversed~even under transient conditions. With reverse voltages greater than 1V. the IC will conduct excessive current, fuzing internal
aluminum interconnects. If there is a possibility of this happening, clamp diodes
with a high peak curren~ rating should be installed on the supply lines. Reversal of
the voltage between V and V- will always cause a problem, although reversals
with respect to ground may also give difficulties in many circuits.
Isolating Large Capacitive Loads
r--""'.....~_"n""
The minimum values given for the frequency compensation capacitor are stable
only for source resistances less than 10 kn. stray capacitances on the summing
junction less than 5 pF and capacitive loads small.r than 100 pF. If any of these
conditions are not met, it becomes necessarv to overcompensate the amplifier
with a larger crompensation capacitor. Alternately, lead capacitors can be used in
the feedback network to negate the effect of stray capacitance and large feedback
resistors or an RC network can be added to isolate capacitive loads.
Although the LM101A is relatively unaffected by supply bypassing, this cannot
be ignored altogether. Generally it is necessary to bypass the supplies to ground at
least once on every circuit card, and more bypass points may be required if more
than five amplifiers are used. When feed-forward compensation is employed, however, it is advisable to bypass the supply leads of each. amplifier with low
inductance capacitors because of the higher frequencies involved.

Operational Amplifiers
LM301A operational amplifier
general description
example, as a summing amplifier, slew rates of
10 V//ls and bandwidths of 10 MHz can be
realized. In addition, the circuit can be used as a
comparator with differential inputs up to ±30V;
and the output can be clamped at any desired level
to make it compatible with logic circuits.
The LM301A is a general-purpose operational
amplifier which features improved performance
over the 709C and other popular amplifiers.
Advanced processing techniques make possible an
order of magnitude reduction in input currents,
and a redesign of the biasing circuitry reduces the
temperature drift of input current.
The LM301 A provides better accuracy and lower
noise than its predecessors in high impedance
circuitry. The low input currents also make it
particularly well suited for long interval integrators
or timers, sample and hold circuits and low fre·
quency waveform generators. Further, replacing
circuits where matched transistor pairs buffer the
inputs of conventional IC op amps, it can give
lower offset voltage and drift at reduced cost.
This amplifier offers many features which make its
application nearly foolproof: overload protection
on the input and output, no latch-up when the
common mode range is exceeded, freedom from
oscillations and compensation with a single 30 pF
capacitor. It has advantages over internally com·
pensated amplifiers in that the compensation can
be tailored to the particular application. For

LM102 voltage follower
general description
The LM102 is a high·gain operational amplifier de·
signed specifically for unity·gain voltage follower
applications. Built on a single silicon chip, the device
incorporates advanced processing techniques to ob·
tain very low input current and high input imped·
ance. Further, the input transistors are operated at
zero collector·base voltage to virtually eliminate
high temperature leakage currents. It can therefore
be operated in a temperature stabilized component
oven to get extremely low input currents and low
offset voltage drift. Other outstanding characteris·
tics of the device include:
•
•
Fast slewing - 1tlv Ills
Low input current - 10 nA (max)
• High input resistance - 10,000 Mn
• No external frequency compensation required
• Simple offset balancing with optional 1 K poten·
tiometer
• Plug·in replacement for both the LM101 and
LM709 in voltage follower applications.
The LM 102, which is designed to operate with sup·
ply voltages between ±12V and ±15V, also features
low input capacitance as well as excellent small sig·
nal and large signal frequency response - all of
which minimize high frequency gain error. Because
of the low wiring capacitances inherent in mono·
lithic construction, this fast operation can be real·
ized without increasing power consumption.

Nota 1: For operating at elevated temperatures, the device must be derated based on a
150°C maximum junction temperature and a thermal resistance of 45°C/W junction to
case or 1500 CIW junction to ambient (see curve).
Note 2: For supply voltages less than ±15V. the absolute maximum input voltage is equal
to the supply voltage.
Nota 3: Continuous short circuit is allowed for case temperatures to 125°C and ambient
temperatures to 70o e. It is necessary to insert a resistor greater than 2 kH in series with
the input when the amplifier is driven from low impedance sources to prevent damage
when the output is shorted.
Note 4: These specifications apply for TA = 2SoC. Vs = ±1SV and CL :5. 100 pF unless
otherwise noted
Note 5: Increased output swing under load can be obtained by connecting an external
resistor between the booster and V- terminals.See curve.

LM302 voltage follower
general description
The LM302 is a high gain operational amplifier designed specifically for unity-gain voltage follower
applications. Built on a single silicon chip, the
device incorporates advanced processing techniques to obtain very low input current and
high input impedance. Further, the input transistors are operated at zero collector-base voltage
to virtually eliminate high temperature leakage
currents. It can therefore be operated in a
temperature stabilized component over to get
extremely low input currents and low offset
voltage drift. Other outstanding characteristics
of the device include:
• High input resistance - 1,000 Mn
• No external frequency compensation required
• Simple offset balancing with optional 1 K
potentiometer
• Specified for operation from O°C to 70°C
• Plug-in replacement for both the LM201 and
LM709C in voltage follower applications.
The LM302, wh ich is designed to operate with
supply voltages between ±12V and ±15V, also features low input capacitance as well as excellent
small signal and large signal frequency response all of which minimize high frequency gain error.
Because of the low wiring capacitances inherent in
monolithic construction, this fast operation can be
realized without increasing power consumption.
• Fast Slewing - 1OV Ills
• Low input current - 30 nA (max)

Note 1: For operating at elevated temperatures, the device must be derated based on a
85°C maximum junction temperature and a thermal resistance of 45°C/W junction to
case or 150o C/W junction to ambient (see curve).
Note 2: For supply voltages less than ±15V, the absolute maximum input voltage is equal
to the supply voltage.
Note 3: Continuous short circuit is allowed for case temperatures to 70°C and ambient
temperatures to 5SoC. It is necessary to insert a resistor greater than 2 K!1: in series with
me input when the amplifier is driven frC?m low impedance sources to prevent damage
......nen the output is shorted.
Note 4: These specifications apply for T A = 2SOC. Vs = ±15V and CL < 100 pF unless
otherwise noted.

LM107/LM207 operational amplifier
general description
The LM107 and LM207 are complete, general
purpose operational amplifiers, with the necessary
frequency compensation built into the chip. Advanced processing techniques make the input
currents a factor of ten lower than industry
standards like the 709. Yet, they are a direct,
plug-in replacement for the 709, LM10l, LM101A
and 741. Specifications which have been improved
include:
• Offset voltage 3 mV maximum over temperature
• Input current 100 nA maximum over temperature
• Offset current 20 nA maximum over temperature
• Guaranteed drift characteristics
• Offsets guaranteed over entire common mode
range
The LM 107 series offers the features of the
LM10l, which makes its application nearly foolproof. In addition, the device provides better
accuracy and lower noise in high impedance
circuitry. The low input currents also make it
particularly well suited for long interval integrators
or timers, sample and hold circuits and low
frequency waveform generators. Further, replacing
circuits where matched transistor pairs buffer the
inputs of conventional Ie op amps, it can give
lower offset voltage and drift at a lower cost.
The LM207 is identical to the LM 107, except that
the LM207 has its performance guaranteed over a
_25°e to 85°e temperature range, instead of
-55°e to 125°e.

Note 1: The maximum junction temperature of the LM107 is lS0·C, while that of the LM207 is IOO·C_ For operating at
elevated temperatures, devices in the TO-5 package must be derated based on a thermal resistance of 150°C/W, junction to
ambient, or 4SoC/W, junction to case. For the flat package, the derating is based on a thermal resistance of 18SoC/W when
mounted on a 1I16-inch-thick epoxy glass board with ten, O.03-inch-wide, 2-ounce copper conductors. The thermal resistance
of the dual-in-line package is 100°C/W, junction to ambient.
Note 2: For supply voltages less than ±1SV. the absolute maximum input voltage is equal to the supply voltage.
Note 3: These specifications apply for ±SV ::; Vs ::; ±20V and --5SoC ::; TA ::; 12SoC for the LMl07 or -2S·C ::; TA 8SoC

of ten lower than industry standards like the
709C. Yet, it is a direct, plug·in replacement for

In addition to reduced input current, the offset
voltage and offset current are guaranteed over the
entire common mode range and maximum drift
specifications are given. The amplifier also offers
many features which make its application nearly
foolproof: overload protection on the input and
output, no latch·up when the common mode range
is exceeded, as well as freedom from oscillations.
The LM307 provides better accuracy and lower
noise than its predecessors in high impedance
circuitry. The low input currents also make it

LM108/LM208 operational amplifier
general description
The LM10B and LM20B are precision operational
amplifiers ,having specifications a factor of ten
better than FET amplifiers over a -55°C to 125°C
temperature range, Selected units are available
with offset voltages less than 1,0 mV and drifts
less than 5 /lvtc, again over the military temperature range_ This makes it possible to eliminate
offset adjustments, in most cases, and obtain
performance approaching chopper stabilized
amplifiers.
• Maximum input bias current of 3.0 nA over
temperature
• Offset current less than 400 pA over temperature
• Supply current of only 300/lA, even in saturation
• Guaranteed drift characteristics
The low current error of the LM 1OB series makes
possible many designs that are not practical with
conventional amplifiers. In fact, it operates from
10 Mn source resistances, introducing less error
than devices like the 709 with 10 kn sources.
Integrators with drifts less than 500 /lV /sec and
analog time delays in excess of one hour can be
made using capacitors no larger than 1 /IF.
The devices operate with supply voltages trom
±2V to ±20V and have sufficient supply rejection
to use unregulated supplies. Although the circuit
is interchangeable with and uses the same compensation,as the LM101A, an alternate compensation
scheme can be used to make it particularly insensitive to power supply noise and to make supply
bypass capacitors unnecessary. Outstanding characteristics include:
The LM20B is identical to the LM108, except that
the LM208 has its performance guaranteed over a
_25°C to 85°C temperature range, instead of
_55°C to 125°C.

Not~ 1: The maximum junction temperature of the LM108 is 150°C. while that of the LM208 is
100 C. For operating at elevated temperatures, devices in the TO·5 package must be derated based on
a thermal resistance of 150o C/W. junction to ambient, or 4SoC/W. junction to case. For the flat
package, the derating is based on a thermal resistance of 185°C/W when mounted on a 1/16·inch·thick
epoxy glass board with tell. O.03-inch-wide, 2-ounce coppet conductors. The thermal resistance of the
dual-in-line package is 100 C/W, junction to ambient.
Note 2: The inputs are shunted with back-to-back diodes for· overvoltage protection. Therefore,
excessive current will flow if a differential input voltage in excess of 1V is applied between the inputs
unless some limiting resistance is used.
Note 3: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the
supply voltage.

lM308 operational amplifier
general description
The LM308 is a precision operational amplifier
featuring input currents nearly a thousand times
lower than industry standards like the LM709C. In
fact, its performance approaches that of high
quality FET amplifiers. The circuit is directly
interchangeable with the LM301 A in low frequency circuits and incorporates the same protective features which make its application nearly
foolproof.
The device operates with supply voltages from
±2V to ±15V and has sufficient supply rejection to
use unregulated supplies. Although the circuit is
designed to work with the standard compensation
for the LM301 A, an alternate compensation
scheme can be used to make it particularly insensitive to power supply noise and to make supply
bypass capacitors unnecessary. Power consumption is extremely low, so the amplifiers are ideally
suited for battery powered applications. Out-
standing characteristics include:
• Maximum input bias current of 7.0 nA
• Offset current less than 1.0 nA
• Supply current of only 300 J1.A, even in saturation
• Guaranteed drift characteristics
The low current error of the· LM308 makes possible many designs that are not practical with conventional amplifiers. In fact, it operates from
10 Mn source resistances, introducing less error
than devices like the 709C with 10 kn sources.
I ntegrators with worst case drifts less than
1 mV {sec and analog time delays in excess of one
hour can be made using capacitors no larger than
1 J1.F. The device is well suited for use with piezoelectric, electrostatic or other capacitive transducers, in addition to low frequency active filters
with small capacitor values.

Not8 1: The maximum junction temperature of the LM308 is 8SoC. For operating at elevatect temperatures, devices in the TO-5 package must be derated based on a thermal resistance of 150 CIW,
junction to ambient, or 4~oC/W .. junction to case. For the flat package. the derating is based on a
thermal resistance of 185 C/W when mounted on a 1/16-inch-thick epoxy glass board with ten,
O.03-inch-wide, 2-ounce copper conductors. The thermal resistance of the dual-in-line package is
100oC/W, junction to ambient.
Note 2: The inputs are shunted with back-ta-back diodes for overvoltage protection. Therefore,
excessive current will flow if a differential input voltage in excess of 1 V is applied between the inputs
unless some limiting resistance is used.
Note 3: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the
supply voltage.
Note 4: These specifications apply for ±5V ~ Vs ~±15V and OOC ~TA ~70oC, unless otherwise
specified.

The LM10BA, LM20BA and LM30BA are precision
operational amplifiers having specifications about
a factor of ten better than FET amplifiers over
their operating temperature range. In addition to
low input currents, these devices have extremely
low offset voltage, making it possible to eliminate
offset adjustments, in most cases, and obtain
performance a pproaching chopper stabilized
amplifiers.

~

The devices operate with supply voltages from
±2V to ±20V and have sufficient supply rejection
to use unregulated supplies. Although the circuit is
interchangeable with and uses the same compensa·
tion as the LM101A, an alternate compensation
scheme can be used to make it particularly insensi·
tive to power supply noise and to make supply
bypass capacitors unnecessary. Outstanding char·
acteristics include:
• Offset voltage guaranteed less than 0.5 mV
• Maximum input bias current of 3.0 nA over
temperature
• Offset current less than 400 pA over tempera·
ture
• Supply current of only 300J.lA, even in
saturation
• Guaranteed 5 J.lvre drift.
The low current error of the LM 1OBA series makes
possible many designs that are not practical with
conventional amplifiers. In fact, it operates from
10 Mn source resistances, introducing less error
than devices like the 709 with 10 kn sources. Inte·
grators with drifts less than 500 J.lV /sec and analog
time delays in excess of one hour can be made
using capacitors no larger than 1 J.lF.
The LM20BA is identical to the LM 10BA, except
that the LM20BA has its performance guaranteed
over a -25°C to B5°e temperature range, instead
of _55°C to 125°C. The LM30BA has slightlyrelaxed specifications and has its performance
guaranteed over a oOe to 70°C temperature range.

LM110/LM210 voltage follower
general description
The LM110 and LM210 are monolithic opera·
tional amplifiers internally connected as unity·
gain non· inverting amplifiers. They use super·
gain transistors in the input stage to get low
bias current without sacrificing speed. Directly
interchangeable with 101, 741 and 709 in voltage
follower applications, these devices have internal
frequency compensation and provision for offset
balancing. Outstanding characteristics include:
• Input current: 10 nA max. over temperature
The LM110 and LM210 are useful in fast sample
and hold circuits, active filters or as general·
purpose buffers. Further, the frequency response
is enough better than standard IC amplifiers
that the followers can be included in the feedback
loop without introducing instability. They are
plug·in replacements for the LM102 or LM202
voltage followers, offering lower offset voltage,
drift, bias current and noise in addition to higher
speed and wider operating voltage range.
• Small signal ba.ndwidth: 20 MHz
• Slew rate: 30V Ills
• Supply voltage range: ±5V to ±18V
The LM210 is identical to the LM110, except that
its performance is specified over a _25°C to 85°C
temperature range instead of _55°C to 125°C.

tance of the duaHn-line package is 10Qoe/W, junction to ambient.
Note 2: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the
supply voltage.
Note 3: Continuous short circuit is allowed for case temperatures to 125°C and ambient temperatures to 70°C. It is necessary to insert a resistor greater than 2kO in series with the input when the
amplifier is driven from low impedance sources to prevent damage when the output is shorted.
Note 4: These specifications apply for ±5V ::;;Vs ::;;±18V and -550C::;;T A::;; 125°C, unless otherwise
specified. With the LM210, however, all temperature specifications are limited to -2SoC::;T A ::;SSoC.

the booster and V- terminals. See curve.

general description
The LMl12 and LM212 are micropower operational amplifiers with very low offset-voltage and
input-current errors-at least a factor of ten better
than FET amplifiers over a -55°C to 125°C
temperature range. Similar to the LM 108 series,
that also use sUpergain transistors, * they differ in
that they include internal frequency compensation
and have provisions for offset adjustment with a
single potentiometer.
These amplifiers will operate on supply voltages of
±2V to ±20V, drawing a quiescent current of only
300/lA. Performance is not appreciably affected
over this range of voltages, so operation from
unregulated power sources is easily accomplished.
They can also be run from a single supply like the
5V used for digital circuits. Some noteworthy
features are:
• Maximum input bias current of 3.0 nA over
tem peratu re
• Offset current less than 400 pA over temperature
• Low noise
• Guaranteed drift specifications
The LMl12 series are the first IC amplifiers to
improve reliability by including overvoltage protection for the MOS compensation capacitor.
Without this feature, IC's have been known to
su ffer catastrophic failure caused by shortduration overvoltage spikes on the supplies. Unlike
other internally-compensated IC amplifiers, it is
possible to overcompensate with an external
capacitor to increase stability margin.
The LM212 is identical to the LMl12, except that
the LM212 has its performance guaranteed over a
-25°C to 85°C temperature range instead of
_55° C to 125° C.

Nots 1: The maximum junction temperature of the LM112 is 150°C, while that of the LM212 is
100 C. For operating at elevated temperatures, devIces in the TO-5 package must be derated based on
a thermal resistance of 150o C/W, junction to ambient, or 45°C/W, junction to case. For the flat
package, the derating is based on a thermal resistance of 18SoC/W when mounted on a 1/16-inch-thick
epoxy glass board with tep, O.03-inch-wide, 2-ounce copper conductors. The thermal resistance of the
dual·in-line package is 100 ~/W, junction to ambient.
Note 2: The inputs are shunted with shunt diodes for overvoltage protection. Therefore, excessive
current will flow if a differential input voltage in excess of 1 V is applied between the inputs unless
some limiting resistance is used.
Note 3: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the
supply voltage.
Note 4: These specifications apply for ±5V ~ Vs ~ ±20V and -55°C ~ T A ~ 125°C, unless otherwise
specified.

general description
The LM312 is a micropower operational amplifier
with very low offset voltage and i'nput-current
errors-approaching that of FET amplifiers over its
operating temperature range_ Similar to the LM308
series, that also uses supergain transistors t , it differs in that it includes internal frequency compensation and has provisions for offset adjustment

overvoltage spikes on the supplies. Unlike other
internally-compensated IC amplifiers, it is possible
to overcompensate with an external capacitor to
increase stability margin.
The low current error of the LM312 makes
possible many designs that are not practical with
conventional amplifiers. In fact, it operates from
10 Mn source resistances, introducing less error
than devices like the l09C with 10 kn sources_
Integrators with worst case drifts less than 1 mV I
sec and analog time delays in excess of one hour
can be made using capacitors no larger than l/lF.
The device is well suited for use with piezo-electric,
electrostatic or other capacitive tranducers, in
addition to low frequency active filters with small
capacitor values.

LM216/LM216A/LM316/LM316A operational amplifier
general description
These devices are precision, high input impedance
operational amplifiers designed for applications
requiring extremely low input-current errors. They
use supergain transistors in a Darlington input
stage to get input bias currents that are equal to
high-quality FET amplifiers-even in limited temperature range operation. The low input current is,
however, obtained with some sacrifice to offset
voltage, offset voltage drift and noise when compared to the non-Darlington LM 112 series. Noteworthy specifications include:
• Guaranteed bias currents as low as 50 pA
•
Maximum offset currents down to 15 pA
• Operates from supplies of ±3V to ±20V
• Supply current only 300 /J.A at ±20V
These operational amplifiers are internally frequency compensated and have provisions for offset
balancing with a single external potentiometer.
Further, unlike most other internally compensated
amplifiers, the MOS compensation capacitor is
protected to prevent catastrophic failure from
overvoltage spikes on the supplies.
The low current error of these amplifiers make
possible many designs that were previously impractical with monolithic amplifiers. They will
operate from 100 M.\1 source resistances, introducing less error than general purpose amplifiers
with 10 k.\1 sources. Integrators with worst case
drifts less than 10/J.V/sec and analog time delays in
excess of one day can also be made using capacitors no larger than 1 /J.F.
The LM216A and LM316A are high performance
versions of the LM216 and LM316. The LM216
and LM216A are specified for operation from
_25°C to 85°C, while the LM316 and LM316A
are specified from 0° C to 55° C.

LM118/LM218 operational amplifier
general description
The LM118 and LM218 are precision high speed
operational amplifiers designed for applications
requiring wide bandwidth and high slew rate. They
feature a factor of ten increase in speed over gen·
eral purpose devices without sacrificing DC performance.
compensated amplifiers, external frequency com
pensation may be added for optimum performance
For inverting applications, feedforward compen
sat ion will boost the slew rate to over 150V Ips
and almost double the bandwidth. Overcompensa·
tion can be used with the amplifier for greater
stability when maximum bandwidth is not needed.
Further, a single capacitor can be added to reduce
the 0.1% settling time to under 1 ps.
features

Pin compatible with general purpose op amps
The high speed and fast settl ing time of these op
amps make them useful in AID converters, oscillators, active filters, sample and hold circuits, or
general purpose amplifiers. These devices are easy
to apply and offer an order of magnitude better
AC performance than industry standards such as

The LM 118 has internal unity gain frequency com·
pensation. This considerably simplifies its application since no external components are necessary
for operation. However, unlike most internally
The LM218 is identical to the LMl18 except that
the LM218 has its performance specified over a
_25°C to 85°C temperature range, instead of
_55°C to 125°C.

Note 1: The maximum junction temperature of the LMl18 is 150°C. while that of the LM218 is
lOOoe. For operating at elevated temperatures, devices in the TO-S package must be derated based on
a thermal resistance of 150°C/W. junction to ambient, or 4S o C/W, junction to case. For the flat package, the derating is based on a thermal resistance of 18SoC/W when mounted on a 1/16-inch-thick
epoxy glass board with ten, O.03-inch-wide, 2'Qunce copper conductors. The thermal resistance of the
dual-in-line package is lOOoe/W. junction to ambient.
Note 2: The inputs are shunted with back-ta-back diodes for overvoltage protection. Therefore,
excessive current will flow if a differential input voltage in excess of lV is applied between the inputs
unless some limiting resistance is used.
Note 3: For supply voltages less than ±lSV, the absolute maximum input voltage is equal to the
supply VOltage:
Note 4: These specifications apply for ±5V ~ Vs ~ ±20V and _55°C 5. T A ~ 125°C, unless otherwise specified. With the LM218, however, all temperature specifications are limited to -2SoC.s. TA ~
85°C. Also, power supplies must be bypassed with 0.1 ~F disc capacitors.

LM1211LM2211LM321 precision preamplifier
general description
The LM121 series are precision preamplifiers
designed to operate with general purpose opera·
tional amplifiers to drastically decrease DC errors.
Drift, bias current, common mode and supply
rejection are more than a factor of 10 better than
standard op amps alone. Further, the added DC
gain of the LM121 decreases the closed loop gain
error.
The LM121 operates with supply voltages from
±3V to ±20V and has sufficient supply rejection
to operate from unregulated supplies. The operat·
ing current is programmable from 5J.1A to 200J.lA
so bias current, offset current, gain and noise can
be optimized for the particular application while
still realizing very low drift. Super·gain transistors
are used for the input stage so input error currents
are lower than conventional amplifiers at the same
operating current. Further, the initial offset voltage
is easily nulled to zero.
advantages
•
•
Permits optimization of general purpose op amps
Replaces many specialized op amps
features
• Guaranteed drift less than 1J.1V1°C when nulled
• Offset voltage less than 0.7 mV
•
Bias current less than 10 nA at 10J.lA operating
current
• CMRR 120dB minimum
•
114 dB supply rejection
•
Easily nulled offset voltage
The extremely low drift of the LM121 will improve
accuracy on al most any precision DC circuit. For
example, instrumentation amplifier, strain gauge
amplifiers and thermocouple amplifiers now using
chopper amplifiers can be made with the LM121.
The full differential input and high common mode
rejection are another advantage over choppers. For
applications where low bias current is more impor·
tant than drift, the operating current can be reo
duced to low values. High operating currents can
be used for low voltage noise with low source
resistance. The programmable operating current of
the LM121 allows tailoring the input character·
istics to match those of special ized op amps.
The LM121

is specified over a -55°C to 125°C

A lower drift version of the LM121 - the LM121A
series - is available for applications requiring
0.2J.1V 1°C offset voltage drift.

frequency compensation
Universal Frequency Compensation
Alternate Compensation
The additional gain of the LM121 preamplifier
when used with an operational amplifier usually
necessitates additional frequency compensation.
When the closed loop gain of the op amp with the
LM121 is less than the gain of the LM121 alone,
more compensation is needed. The worst case
situation is when there is 100% feedback - such
as a voltage follower or integrator - and the gain
of the LM121 is high. When high closed loop gains
are used - for example Av = 1000 - and only
an addition gain of 200 is inserted by the LM121,
the frequency compensation of the op amp will
usually suffice.
The two compensation capacitors can be made
equal for improved power supply rejection. In this
case the formula for the compensation capacitor
is
The frequency compensation shown here is designed·
to operate with any unity·gain stable op amp.
Figure 1 shows the basic configuration of frequency
stabilizing network. In operation the output of the
LM121 is rendered single ended by a O.OlMF
bypass capacitor to ground. Overall frequency
compensation then is achieved by an integrating
capacitor a~ound the op amp.
Table 1 shows typical values for the two compensating capacitors for various gains and operating
currents.

The LM121 A series are precision preamplifiers designed
to operate with general purpose operational amplifiers to
drastically decrease dc errors. Drift, bias current, common
mode and supply rejection are more than a factor of 50
better than standard op amps alone. Further, the added
dc gain of the LM 121 A decreases the closed loop gain
error.

Guaranteed drift less than 0.2p.V I"c when nulled
Offset voltage less than 0.4 mV
Bias current less than 10 nA at 10p.A operating current
CMRR 126 dB minimum
120 dB supply rejection
Easily nulled offset voltage
The extremely low drift of the LM121A will improve
accuracy on almost any precision dc circuit. For example,
instrumentation amplifier, strain gauge amplifiers and
thermocouple amplifiers now using chopper amplifiers
can be made with the LM 121 A. The full differential in·
put and high common·mode rejection are another
advantage over choppers. For applications where low bias
current is more important than drift, the operating cur·
rent can be reduced to low values. High operating cur·
rents can be used for low voltage noise with low source
resistance. The programmable operating current of the
LM121A allows tailoring the input characteristics to
match those of specialized op amps.
The LM 121 A operates with supply voltages from ±3V
to ±20V and has sufficient supply rejection to operate
from unregulated supplies. The operating current is pro·
grammable from 5p.A to 200p.A so bias current, offset
current, gain and noise can be optimized for the particu·
lar application while still realizing very low drift. Super·
gain transistors are used for the input stage so input error
currents are lower than conventional amplifiers at the
same operatirig current. Further, the initial offset voltage
is easily nulled to zero.
advantages
The LM121A is specified over a -55°C to +125°(;
temperature range, the LM221A over a -25°C to +85°C
range and the LM321A over a O°C to +70°C tempera'
ture range.

Note 1: The maximum junction temperature of the LM121A is 1S0°C, while that of the LM221A is 100°C. The maximum junction temperature
of the LM321A is 8SoC. For operating at elevated temperature, devices in the TO·S package must be derated based on a thermal resistance of
1S0°CIW, junction to ambient, or 4SoC/W, junction to case. For the flat package, the derating is based on a thermal resistance of 18SoC/W when
mounted on a 1/B·inch·thick epoxy glass board with ten, 0.03-inch wide, 2-ounce copper conductors. The thermal resistance of the dual-in-line
package if 100°C/W junction to ambient.
Note 2: The inputs are shunted with back-to-back diodes in series with a soon resistor for overvoltage protection. Therefore, excessive current
will flow if a differential input voltage in excess of 1V is applied between the inputs.
Note 3: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
Note 4: These specifications apply for ±5 ~ Vs < ±20V and -55°C ~ TA ~ 125°C, unless otherwise specified. With the LM221A, however, all
temperature specifications are limited to -2SoC ::5 TA ::5 8SoC, and for the LM321A the specifications apply over a O°C to 70°C temperature
range.
Note 5: External precision resistor-O.1%-can be placed from pins 1 and 8 to 7 to increase positive common-mode range.
frequency compensation
UNIVERSAL COMPENSATION
ALTERNATE COMPENSATION
The additional gain of the LM 121 A preamplifier when
used with an operational amplifier usually necessitates
additional frequency compensation. When the closed
loop gain of the op amp with the LM121 A is less than
the gain of the LM121 A alone, more compensation is
needed. The worst case situation is when there is 100%
feedback-such as a voltage follower or integrator-and
the gain of the LM121A is high. When high closed loop
gains are used-for example Av = 1000-and only an
addition gain of 200 is inserted by the LM121A, the frequency compensation of the op amp will usually suffice.
The two compensation capacitors can be made equal for
improved power supply rejection. In this case the formula for the compensation capacitor is:
B
Table I shows typical values for the two compensating
capacitors for various gains and operating currents.

GAIN
The frequency compensation shown here is designed to
operate with any unity·gain stable op amp. Figure 1
shows the basic configuration of frequency stabilizing
network. In operation the output of the LM121A is
rendered single ended by a O.OlJ.lF bypass capacitor to
ground. Overall frequency compensation then is achieved
by an integrating capacitor around the op amp.

Operational Amplifiers
LM124/LM224/LM324 quad op amps
general description
advantages
The LM124 series consists of four independent, high
gain, internally frequency compensated operational amplifiers which were designed specifically to operate from
a single power supply over a wide range of voltages.
Operation from split power supplies is also possible and
the low power supply current drain is independent of the
magnitude of the power supply voltage.
•
Eliminates need for dual
•
Four internally compensated op amps in a single
package
•
Allows directly sensing near GND and V OUT also
goes to GND
•
Compatible with all forms of logic
•
Power drain suitable for battery operation
Application areas include transducer amplifiers, dc gain
blocks and all the conventional op amp circuits which
now can be more easily implemented in single power
supply systems. For example, the LM 124 series can be
directly operated off of the standard +5 V DC power
supply voltage which is used in digital systems and will
easily provide the required interface electronics without
requiring the additional ±15 V DC power supplies.

Note 1: For operating at high temperatures, the LM324 must be derated based on a +12SoC maximum junction temperature and a thermal
resistance of 175°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM224 and LM124
can be derated based on a +150°C maximum junction temperature. The dissipation is the total of all four amplifiers-use external resistors, where
possible, to allow the amplifier to saturate or to reduce the power which is dissipated in the integrated circuit.
Note 2: Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately
40 rnA independent of the magnitude of V+. At values of supply voltage in excess of +15 VDC. continuous short-circuits can exceed the power
dissipation ratings and cause eventual destruction.
Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of
the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral
NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the op amps to go to the V+ voltage level (or
to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will
re-establish when the input voltage, which was negative, again returns to a value greater than -0.3 VDC.

Note 6: The direction of the input current is out of the Ie due to the PNP input stage. This current is essentially constant, independent of the
state of the output so no loading change exists on the input lines.
Note 7: The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of
the common-mode voltage range is V+ - 1.5V. but either or both inputs can go to +32 V DC without damage.
Note 8: Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This
typically can be detected as this type of capacitive coupling increases at higher frequencies.

application hints
The LM124 series are op amps which operate with only
a single power supply voltage, have true-differential
inputs, and remain in the linear mode with an input
common-mode voltage of 0 V DC- These amplifiers
operate over a wide range of power supply voltage with
little change in performance characteristics_ At 25°C
amplifier operation is possible down to a minimum
supply voltage of 2_3 VDC -
be used, from the output of the amplifier to grou nd to
increase the class A bias current and prevent crossover
distortion_ Where the load is directly coupled, as in dc
applications, there is no crossover distortion_
Capacitive loads which are applied directly to the output
of the amplifier reduce the loop stability margin_ Values
of 50 pF can be accommodated using the worst-case noninverting unity gain connection_ Large closed loop gains
or resistive isolation should be used if larger load
capacitance must be driven by the amplifier_
The pinquts of the package have been designed to
simplify PC board layouts_ Inverting inputs are adjacent
to outputs for all of the amplifiers and the outputs have
also been placed at the corners of the package (pins 1,
7, 8, and 14)_
The bias network of the LM 124 establishes a drain
current which is independent of the magnitude of the
power supply voltage over the range of from 3 V DC to
30 V DC-
Precautions should be taken to insure that the power
supply for the integrated circuit never becomes reversed
in polarity or that the unit is not inadvertently installed
backwards in a test socket as an unlimited current surge
through the resulting forward diode within the IC could
cause fusing of the internal conductors and result in a
destroyed unit_
Output short circuits either to ground or to the positive
power supply should be of short time duration_ Units
can be destroyed, not as a result of the short circuit
current causing metal fusing, but rather due to the large
increase in IC chip dissipation which will cause eventual
failure due to excessive junction temperatures_ Putting
direct short-circuits on more than one amplifier at a time
will increase the total IC power dissipation to destructive
levels, if not properly protected with external dissipation
limiting resistors in series with the output leads of the
amplifiers_ The larger value of output source current
which is available at 25°C provides a larger output current capability at elevated temperatures (see typical
performance characteristics) than a standard IC op amp_
Large differential input voltages can be easily accommodated and, as input differential voltage protection
diodes are not needed, no large input currents result
from large differential input voltages_ The differential
input voltage may be larger than V+ without damaging
the device_ Protection should be provided to prevent the
input voltages from going negative more than -0_3 V DC
(at 25° C)_ An input clamp diode with a resistor to the
IC input terminal can be used_
To reduce the power supply current drain, the amplifiers
have a class A output stage for small signal levels which
converts to class B in a large signal mode_ This allows the
amplifiers to both source and sink large output currents_
Therefore both NPN and PNP external current boost
transistors can be used to extend the power capability of
the basic amplifiers_ The output voltage needs to raise
approximately 1 diode drop above ground to bias the
on-chip vertical PNP transistor for output current sinking
applications_
The circuits presented in the section on typical applications emphasize operation on only a single power supply
voltage_ If complementary power supplies are available,
all of the standard op amp circuits can be used_ In
general. introducing a pseudo-ground (a bias voltage
reference of V+/2) will allow operation above and below
this value in single power supply systems_ Many application circuits are shown which take advantage of the wide
input common-mode voltage range which includes
ground_ In most cases, input biasing is not required and
input voltages which range to ground can easily be
accommodated_
For ac applications, where the load is capacitively
coupled to the output of the amplifier, a resistor should

Operational Amplifiers
LM143/LM343 high voltage operational amplifier
general description
features
The LM143 is a general purpose high voltage operational
amplifier featuring operation to ±40V, complete input
overvoltage protection up to ±40V and input currents
comparable to those of other super-{l op amps. Increased
slew rate, together with higher common·mode and supply rejection, insure improved performance at high sup·
ply voltages. Operating characteristics, in particular
supply current, slew rate and gain, are virtually independent of supply voltage and temperature. Furthermore,
gain is unaffected by output loading at high supply voltages due to thermal symmetry on the die. The LM 143
is pin compatible with general purpose op amps and has
offset null capability.
Application areas include those of general purpose op
amps, but can be extended to higher voltages and higher
output power when externally boosted. For example,
when used in audio power applications, the LM143 pro·
vides a power bandwidth that covers the entire audio
spectrum. In addition, the LM143 can be reliably
operated in environments with large overvoltage spikes
on the power supplies, where other internally-compensated op amps would suffer catastrophic failure.
The LM343 is similar to the LM143 for applications in
less severe supply voltage and temperature environments.

Note 1: The maximum junction temperature of the LM143 is 150°C, while that of the LM343 is 100°C. For operating at elevated temperatures,
devices in the TO-5 package must be derated based on a thermal resistance of 150°CIW, junction to ambient, or 45°C/W, junction to case. For the
flat package, the derating is based on a thermal resistance of 185°C/W when mounted on a 1/16·inch-thick epoxy glass board with ten, O.03-inchwide, 2-ounce copper conductors. The thermal resistance of the dual-in-line package is 100°C/W, junction to ambient.
Note 2: For supply voltage less than ±40V for the LM143 and less than ±34V for the LM343. the absolute maximum input voltage is equal to the
supply voltage.
Note 3: These specifications apply for Vs = ±28V unless otherwise specified.
For LM143. T A = max = 125°C and T A = min = -55°C.
For LM343. T A = max = 70°C and T A = min = O°C.
Not. 4: The maximum supply currents are guaranteed at Vs = ±40V for the LM143 and Vs = ±34V for the LM343.

application hints
The LM 143 is designed for trouble free operation at any
supply voltage up to and including the guaranteed maximum of ±40V_ Input overvoltage protection, both
common-mode and differential, is 100% tested and
guaranteed at the maximu~ supply voltage_ Furthermore, all possible high voltage destructive modes during
supply voltage turn-on have been eliminated by design_
As with most IC op amps, however, certain precautions
should be observed to insure that the LM 143 remains
virtually blow-out ·proof.
Although output short circuits to ground or either supply
can be sustained indefinitely at lower supply voltages,
these short circuits should be of short duration when
operating at higher supply voltages_ Units can be destroyed by the resulting high power dissipation which
causes failure due to excessive die temperature_ This is
also true when driving low impedance loads or loads that
can revert to low impedance; for example, the LM143
can drive most general purpose op amps outside of their
maximum input voltage range, causing heavy current to
flow and possibly destroying both devices_
Precautions should be taken to insure that the power
supplies never become reversed in polarity-even under
transient conditions. With reverse voltage, the IC will
conduct excessive current, fusing the internal aluminum
interconnects. Voltage reversal between the power supplies will almost always result in a destroyed unit.
,.I
In high voltage applications which are sensitive to very
low input currents, special precautions should be exercised_ For example, with high source resistances, care
should be taken to prevent the magnitude of the PC
board leakage currents, although quite small, from
approaching those of the op amp input currents. These
leakage currents become larger at 12SoC and are made
worse by high supply voltages. To prevent this, PC
boards should be properly cleaned and coated to prevent
contamination and to provide protection from condensed
water vapor when operating below O°C. A guard ring is
also recommended to significantly reduce leakage currents from the op amp input pins to the adjacent high
voltage pins in the standard op amp pin connection as
shown in Figure 1. Figures 2, 3 and 4 show how the
guard ring is connected for the three most common op
amp configurations.
Finally, caution should be exercised in high voltage
applications as electrical shock hazards are present. Since
the negative supply is connected to the case, users may
inadvertantly contact voltages equal to those across the
power supplies.
The LM143 can be used as a plug-in replacement in most
general purpose op amp applications. The circuits presented in the following section emphasize those applications which take advantage of the unique high voltage
capabilities of the LM143.

Operational Amplifiers
LM158/LM25.8/LM358 dual op amps
general description
The LM158 series consists of two independent, high
gain, internally frequency compensated operational amplifiers which were designed specifically to operate from
a single power supply over a wide range of voltages.
Operation from split power supplies is also possible and
the low power supply current drain is independent of the
magnitude of the power supply voltage.
Application areas include transducer amplifiers, dc gain
blocks and all the conventional op amp circuits which
now can be more easily implemented in single power
supply systems. For example, the LM 158 series can be
directly operated off of the standard +5 Vee power
supply voltage which is used in digital systems and will
easily provide the required interface electronics without
requiring the additional ±15 Vec power supplies.
unique characteristics
•
In the linear mode the input common-mode voltage
range includes ground and the output voltage can also
swing to ground, even though operated from only a
single power supply voltage.

LM709 operational amplifier
general description
The LM709 is a monolithic operational amplifier
intended for general-purpose applications_ Operation is completely specified over the range of voltages commonly used for these devices_ The design,
in addition to providing high gain, minimizes both
offset voltage and bias currents_ Further, the class-8
output stage gives a large output capabil ity with
minimum power drain_
External components are used to frequency compensate the amplifier_ Although the unity-gain com-
pensation network specified will make the amplifier
unconditionally stable in all feedback configurations, compensation can be tailored to optimize
high-frequency performance for any gain setting_
The fact that the amplifier is built on a single silicon chip provides low offset and temperature drift
at minimum cost. It also ensures negligible drift
due to temperature gradients in the vicinity of the
amplifier_

LM709A operational amplifier
general description
The LM709A is a monolithic operational amplifier
intended for general-purpose applications. Operation is completely specified over the range of voltages commonly used for these devices. The design,
in addition to providing high gain, minimizes both
offset voltage and bias currents_ Further, the class-B
output stage gives a large output capability with
minimum power drain.
External components are used to frequency compensate the amplifier. Although the unity-gain com-
pensation network specified will make the amplifier
unconditionally stable in all feedback configurations, compensation can be tailored to optimize
high-frequency performance for any gain setting_
The fact that the amplifier is built on a single silicon chip provides low offset and temperature drift
at minimum cost. It also ensures negligible drift
due to temperature gradients in the vicinity of the
amplifier.

lM741/lM741C operational amplifier
general description
The LM741 and LM741C are general purpose
operational amplifiers which feature improved per·
formance over industry standards like the LM709.
They are direct, plug·in replacements for the
709C, LM201, MC1439 and 748 in most
applications.
The offset. voltage and offset current are guaran·
teed over the entire common mode range. The
amplifiers also offer many features which make
their application nearly foolproof: overload pro·
·tection on the input and output, 110 latch·up when
the common mode range is exceeded, as well ~s
freedom from oscillations.
The LM741 C i's identical to the LM741 except
that the LM741 C has its performance guaranteed
over a DoC to 70°C temperature range, instead of
_55°C to 125°C.

a thermal resistance of 150°C/W, junction to ambient, or 4SoC/W. junction to case. For the flat
package, the derating is based on a thermal resistance of 18SoC/W when mounted on a 1/16-inchthick epoxy glass board with ten, O.03-inch-wide, 2-ounce copper conductors. The thermal resistance of the dual-in-Iine package is 100o e/W, junction to ambient.
Note 2: For supply voltages less than ±15V, the absolute maximum input voltage is equal to the
supply voltage.
Note 3: These specifications apply for Vs = ±15V and -5SoC ~ TA ~ 12SoC, unless otherwise
specified. With the LM747C, however, all specifications are limited to

LM748/LM748C operational amplifier
general description
The LM748/LM748C is a general purpose operational amplifier built on a single silicon chip. The
resulting close match and tight thermal coupling
gives low offsets and temperature drift as well as
fast recovery from thermal transients. In addition,
the device features:
• Frequency compensation with a single 30 pF
capacitor
• Operation from ±5V to ±20V
• Low current drain: 1.8 mA at ±20V
• Continuous short-circuit protection
• Operation as a comparator with differential inputs as high as ±30V
• No latch-up when common mode range is
exceeded.
• Same pin configuration as the LM101.
The unity-gain compensation specified makes the
circuit stable for all feedback configurations, even
with capacitive loads. However, it is possible to
optimize compensation for best high frequency
performance at any gain. As a comparator, the
output can be clamped at any desired level to make
it compatible with logic circuits.
The LM748 is specified for operation over the
-55°C to +125°C military temperature range. The
LM748C is specified for operation over the O°C
to +70°C temperature range.

LM2900 quad amplifier
general description
features
The LM2900 consists of four independent, dual
input, internally compensated amplifiers which
were designed specifically for automotive and
industrial applications. They operate off a single
power supply voltage and provide a large output
voltage swing. These amplifiers make use of a
current mirror to achieve the non·inverting input
function.
Applications include: AC amplifiers, RC active
filters; low frequency triangle, squarewave and
pulse waveform generation circuits; tachometers
and low speed, high voltage digital logic gates.
For additional information, see Application Note
72, "The LM3900 - A New Current-Differencing
Quad of ± Input Ampl ifiers."

Note 1: For operating at high temperatures, the device must be derated based on a 12SoC maximum junction temperature and
a thermal resistance of 17SoC/W which applies for the device soldered in a printed circuit board, operating in a still air ambient.
Note 2: When used as a "non-inverting amplifier" (see bottom of page 1) the gain-bandwidth product is not limited to 2.5 MHz.
The isolation provided by the "current mirror" allows a constant unity voltage gain feedback for the main inverting amplifier.
This means that large values of gain can be achieved at high frequencies and the dominate limit is due to the slew rate of the
amplifier. For example: a voltage gain of 100 is easily obtained at 1 MHz and an output voltage swing of 160 mVp-p can be
achieved prior to slew rate limiting. This operational mode is useful for signal frequencies in the 50 kHz to 1 MHz range as would
be encountered in I F or carrier frequency applications.
Note 3: The output current sink capability can be increased for large signal conditions by overdriving the inverting input. This
is shown in the section on Typical Characteristics.
Note 4: This spec indicates the current gain of the current mirror which is used as the non-inverting input.
Note 5: Input Vee match between the non-inverting and the inverting inputs occurs for a mirror current (non-inverting
input current) of approximately 10 $lA. This is therefore a typical design center for many of the application circuits.
Nots 6: Clamp transistors are included on the IC to prevent the input voltages from swinging below ground more than
approximately -0.3 VOC. The negative input currents which may result from large signal overdrive with capacitance input
coupling need to be externally limited to values of approximately 1 rnA. Negative input currents in excess of 4 mA will cause
the output voltage to drop to a low voltage. This maximum current applies to anyone of the input terminals. If more than one
of the input terminals are simultaneously driven negative smaller maximum currents are allowed. Common-mode current biasing can be used to prevent negative input voltages; for example. see the "Differentiator Circuit" in the applications section.

amplifiers which were designed specifically for
automotive and industrial control systems. They
operate from a single power supply over a wide
range of voltages. Operation from split power
supplies is also possible and the low power supply
current drain is independent of the magnitude of
the power supply voltage.
In the linear mode the input common-mode
voltage range includes ground and the output
voltage can also swing to ground, even though
operated from only a single power supply
voltage.
• The unity gain -cross frequency is temperature
compensated.
• The input bias current is also temperature
compensated.
Application areas include transducer amplifiers,
DC gain blocks and all the conventional op amp
circuits which now can be more easily implemented
in single power supply systems. For example,
the LM2902 can be directly operated off of the
standard +5V oc power supply voltage which is
used in digital systems and will easily provide the
required interface electronics without requiring
the additional ±15V oc power supplies.

Note 1: For operating at high temperatures, the LM2902 must be derated based on a +12SoC maximum junction temperature
and a thermal resistance of 17So CIW which applies for the device soldered in a printed circuit board operating in a still air
ambient.
Not8 2: Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output
current is approximately 40 rnA independent of the magnitude of V+. At values of supply voltage in excess of +15VOC,
continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction.
Note 3: The direction of the input current is out of the Ie due to the PNP input stage. This current is essentially constant,
independent of the state of the output so no loading change exists on the input lines.
Note 4: The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than
O.3V. The upper end of the common-mode voltage range is V+ - , .6V, but either or both inputs can go to +26VOC without
damage.

application hints
The LM2902 op amps operate with only a
single power supply voltage, have true-differential
inputs, and remain in the linear mode with an
input common-mode voltage of OVDC' These
amplifiers operate over a wide range of power
supply voltage with little change in performance
characteristics. At 25°C amplifier operation is
possible down to a minimum supply voltage of
2.3V DC _
The pinouts of. the package have been designed to
simplify PC board layouts. Inverting inputs are
adjacent to outputs for all of the amplifiers and
the outputs have also been placed at the corners
of the package (pins 1, 7, 8, and 14).
Precautions should be'taken to insure that the
power supply for the integrated circuit never
becomes reversed in polarity or that the unit is not
inadvertently installed backwards in a test socket
as an unlimited current surge through the resulting
forward diode within the IC could cause fUSing of
the internal conductors and result in a destroyed
unit.
Large differential input voltages can be' easily
accommodated and, as input differential voltage
protection diodes are not needed, no large input
currents result from large differential input voltages. The differential input voltage may be larger
than V+ without damaging the device. Protection
should be provided to prevent the input voltages
from going negative more than -0.3V DC (at 25°C).
An input clamp consisting of a diode-connected
NPN transistor (C-B short) can be .used.
To reduce the power supply current drain, the
amplifiers have a class A output stage for small
signal levels which converts to class B in a large
signal mode. This allows the amplifiers to both
source and sink large output currents. Therefore
both NPN and PNP external current boost transistors can be used to extend the power capability
of the basic amplifiers. The output voltage needs
to raise approximately 1 diode drop above ground
to bias the on-chip vertical PNP transistor for
output current sinking applications.
For AC applications, where the load is capacitively
coupled to the output of the amplifier, a resistor
typical single-supply applications
should be used, from the output of the amplifier
to ground to increase the class A bias current and
prevent crossover distortion. Where the load is
directly coupled, as in DC applications, there is no
crossover distortion.
Capacitive loads which are applied directly to the
output of the amplifier reduce the loop stability
margin. Values of 50 pF can be accommodated
using the worst-case non-inverting unity gain connection. Large closed loopgainsor resistive isolation
should be used if larger load capacitance must be
driven by the amplifier_
The bias network of the LM2902 establishes a
drain current which is independent of the magnitude of the power supply voltage over the range
of from 3V oc to 26V DC '
Output short circuits either to ground or to the
positive power supply should be of short time
duration. Units can be destroyed, not as a result
of the short circuit current causing metal fusing,
but rather due to the large increase in IC chip
dissipation which will cause eventual failure due to
excessive junction temperatures. Putting direct
short-circuits on more than one amplifier at a
time will increase the total IC power dissipation to
destructive levels, if not properly protected with
external dissipation limiting resistors in series with
the output leads of the amplifiers. The larger value
of output source current which is available at
25°C provides a larger output current capability
at elevated temperatures (see typical performance
characteristics) than a standard IC op amp.
The circuits presented in the section on typical
applications emphasize operation on only a single
power supply voltage. If complementary power
supplies are available, all of the standard op amp
circuits can be used. In general, introducing a
pseudo-ground (a bias voltage reference of V+12)
will allow operation above and below this value
in single power supply systems. Many application
circuits are shown which take advantage of the
wide input common-mode voltage range which
includes ground. In most cases, input biasing is
not required and input voltages which range to
ground can easily be accommodated.

Note 1: For operating at high temperatures, the device mllst be derated based on a 125°C maximum junction temperature and
a thermal resistance of 17SoCIW which applies for the device soldered in a printed circuit board, operating in a still air ambient.
Note 2: The output current sink capability can be increased for large signal conditions by overdriving the inverting input. Tt;lis
is shown in the section on Typical Characteristics.
Note 3: This spec indicates the current gain of the current mirror which is used as the non-inverting input.
Note 4: Input VBE match between the non~inverting and the inverting inputs occurs for a mirror current (non~inverting
input currend of approximately 10 IlA. This is therefore a typical design center for many of the application circuits.
Note 5: Clamp transistors are included on the Ie to prevent the input voltages from swinging below ground more than
approximately -0.3 VDC. The negative input currents which may result from large signal overdrive with capacitance input
coupling need to be externally limited to values of approximately 1 mAo Negative input currents in excess of 4 mA will cause
the output voltage to drop to a low voltage. This maximum current applies to anyone of the input terminals. If more than one
of the input terminals are simultaneously driven negative smaller maximum currents are allowed. Common~mode current bias~
ing can be used to prevent negative input voltages; see for example the "Differentiator Circuit" in the applications section.

application hints
When driving either input from a low-impedance
source, a limiting resistor should be placed in series
with the input lead to limit the peak input current_
Currents as large as 20 mA will not damage the
device, but the current mirror on the non-inverting
input will saturate and cause a loss of mirror gain
at mA current levels - especially at high operating
temperatures_
Precautions should be taken to insure that the
power supply for the integrated circuit never
becomes reversed in polarity or that the unit is
not inadvertently installed backwards in a test
socket as an unlimited current surge through the
resulting forward diode within the IC could cause
fuzing of the internal conductors and result in a
destroyed unit_
Output short circuits either to ground or to the
positive power supply should be of short time
duration_ Units can be destroyed, not as a result
of the short circu it current causing metal fuzing,
but rather due to the large increase in IC chip
dissipation which will cause eventual failure due
to excessive junction temperatures_ For example,
when operating from a well-regulated +15 VDC
power supply at T A = 25°C with a 100 kn shuntfeedback resistor (from the output to the inverting
input) a short directly to the power supply will not
cause catastrophic failure but the current magnitude will be approximately 50 mA and the junction
temperature will be above TJ max_ Larger feedback
resistors will reduce the current, 11 Mn provides
approximately 30 mA, an open circuit provides
1.3 mA, and a direct connection from the output
to the non-inverting input will result in catastrophic failure when the output is shorted to V+ as
this then places the base-emitter junction of the
input transistor directly across the power supply_
Short-circuits to ground will have magnitudes of
approximately 30 mA and will not cause catastrophic failure at T A '" 25°C_
Unintentional signal coupling from the output to
the non-inverting input can cause oscillations_
This is likely only in breadboard hook-ups with
long component leads and can be prevented by a
more careful lead dress or by locating the noninverting input biasing resistor close to the IC_
A quick check of this condition is to bypass the
non-inverting input to ground with a capacitor.
High impedance biasing resistors used in the noninverting input circuit make this input lead highly
susceptible to unintentional AC signal pickup_
Operation of this amplifier can be best understood
by noticing that input currents are differenced at
the inverting-input terminal and this difference
current then flows through the external feeoback
resistor to produce the output voltage_ Common
mode current biasing is generally useful to allow
operating with signal levels near ground or even
negative as this maintains the inputs biased at
+V BE - Internal clamp transistors (see note 5)
catch negative input voltages at approximately
-0_3 VDC but the magnitude of current flow has
to be limited by the external input network_ For
operation at high temperature, this limit should
be approximately 100 Il-A_
This new "Norton" current-differencing amplifier
can be used in most of the applications of a
standard IC op amp_ Performance as a DC amplifier using only a single supply is not as precise as
a standard IC op amp operating with split supplies
but is adequate in many less critical applications_
New functions are made possible with this amplifier which are useful in single power supply systems_ For example, biasing can be designed separately from the AC gain as was shown in the
"inverting amplifier", the "difference integrator"
allows controlling the charging and the discharging
of the integrating capacitor using only positive
voltages, and the "frequency doubling tachometer"
provides a simple circuit which reduces the ripple
voltage on a tachometer output DC voltage_

general description
The LF111, LF211 and LF311 are FET input voltage
comparators that virtually eliminate input current errors.
Designed to operate over a 5.0V to ±15V range the
LF111 can be used in the most critical applications.
Further, the LF111 can be used in place of the LM111
eliminating errors due to input currents.
advantages
The extremely low input currents of the LF111 allows
the use of a simple comparator in applications usually
requiring input current buffering. Leakage testing, long
time delay circuits, charge measurements, and high
source impedance voltage comparisons are easily done.
•
Eliminates input current errors
•
Interchangeable with LM 111

Not. 2: The maximum junction temperature of the LFlll is +150° C, the LF211 is +110° C and the LF311 is +85° C. For operating at elevated
temperatures, devices in the TO·5 package must be derated based on a thermal resistance of +150°C/W, junction to ambient, or +45°C/W, junction
to case, For the flat package, the derating is based on a thermal resistance of +185° C/W when mounted on a l/IS-inch·thick epoxy glass board with
ten, 0.03-inch·wide, 2·ounce copper conductors. The thermal resistance of the dual·in·line package is+l OO°CIW, junction to ambient.
Note 3: These specifications apply for Vs = ± 15V and -55°C < T A < +125°C for the LF111, unless otherwise stated. With the LF211, however,
all temperature specifications are limited to-25°C ~ TA ~ +85°C-and for the LF311 O°C ~ TA ~ +70°C. The offset voltage, offset current and bias
current specifications applv for any supply voltage from a single 5.0 mV supply up to ±15V supplies.
Note 4: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a
1.0 mA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 5: The response time specified (see definitionsl is for a 100 mV input step with 5.0 mV overdrive.
Note 6: For input voltages greater than 15V abov,e the negative supply the bias and offset currents will increase-see typical performance curves.

LM306 voltage comparator/buffer
general description
The LM306 is a high-speed voltage comparator
designed to accurately detect low-level analog signals and drive a digital load. It is equivalent to an
LM710C, combined with a two input NAND gate
and an output buffer. The circuit can drive RTL,
DTL or TTL integrated circuits directly. Furthermore, the output can switch voltages up to 24V at
currents as high as 100 mA. Other features
include:
• Improved accuracy: 5 mV (max) offset
• Fan-out of 10 with DTL or TTL
• Added logic or strobe capability
• Useful as a relay or lamp driver
• Plug-in replacement for the LM710C.
• 40 ns maximum response time
The device has short-circuit protection which
limits the inrush current when it is used to drive
incandescent lamps, in addition to preventing
damage from accidental shorts. The speed is
equivalent to that of an LM710C. However, it is
even faster where buffers and additional logic
circuitry can be eliminated by the increased flexibility of the LM306. It can also be operated from
any negative supply voltage between -3V and
-12V with little effect on performance. The LM306
is identical to the LM 106, except that it is specified
over a 0° C to 70° C temperature range.

LM111/LM211 voltage comparator
general description
., Differential input voltage range: ±30V
The LM 111 and LM211 are voltage comparators
that have input currents nearly a thousand times
lower than devices like the LM106 or LM710.
They are also designed to operate over a wider
range of supply voltages: from standard ±15V op
amp supplies down to the single 5V supply used
for IC logic. Their output is compatible with RTL,
DTL and TTL as well as MOS circuits. Further,
they can drive lamps or relays, switching voltages
up to 50V at currents as high as 50 mAo Out·
standing characteristics include:
• Power consumption: 135 mW at ±15V
Both the inputs and the outputs of the LM 111 or
the LM211 can be isolated from system ground,
and the output can drive loads referred to ground,
the positive supply or the negative supply. Offset
balancing and strobe capability are provided and
outputs can be wire OR'ed. Although slower than
the LM106 and LM710 (200 ns response time vs
40 ns) the devices are also much less prone to
spurious oscillations. The LM 111 tlas the same pin
configuration as the LM106 and LM710.
• Operates from single 5V supply
The LM211 is identical to the LM 111, except that
its performance is specified over a -25°C to 85°C
temperature range instead of _55°C to 125°C.

Note 1: This rating applies for ±15V supplies. The poSitive input voltage limit is 30V above the
negative supply. The negative input voltage limit is equal to the negative supply voltage or 30V below
the positive supply. whichever is less.
Note 2: The maximum junction temperature of the LM111 is 150°C, while that of the LM211 is
110°C. For operating at elevated temperatures, devices in the TO-5 package must be derated based on
a thermal resistance of 150o C/W, junction to ambient, or 4S oC/W. junction to case. For the flat
package, the derating is based on a thermal resistance of 18SoC/W when mounted on a 1/16-inch-thick
epoxy glass board with ten, O.03-inch-wide, 2-ounce copper conductors. The thermal resistance of the
dual-in-line package is 100oC/W, junction to ambient.
Note 3: These specifications apply for Vs = ±15V and -55°C ~TA ~ 125°C, unless otherwise stated.
With the' LM211, however, all temperature specifications are limited to -2SoC ~T A :::;85°C. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5V
supply up to ±15V supplies.
Note 4: The offset voltages and offset currents given are the maximum values required to drive the
output within a volt of either supply with a 1 mA load. Thus, these parameters define an error band
and take into account the worst case effects of voltage gain and input impedance.
Note 5: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.

The LM311 is a voltage comparator that has input
currents more than a hundred times lower than de·
vices like the LM306 or LM710C. It is also de·
signed to operate over a wider range of supply
voltages: from standard ±15V op amp supplies
down to the single 5V supply used for IC logic. Its
output is compatible with RTL, DTL and TTL as
well as MOS circuits. Further, it can drive lamps or
relays, switching voltages up to 40V at currents as
high as 50 mAo
• Maximum offset current: 50 nA
• Differential input voltage range: ±30V
• Power consumption: 135 mW at ± 15V
Both the input and the output of the LM311 can
be isolated from system ground, and the output
can drive loads referred to ground, the positive

and strobe capability are provided and outputs can
be wire OR'ed. Although slower than the LM306

LM119/LM219 high speed dual comparator
general description
The LM119{LM219 are precision high speed dual
comparators fabricated on a single monolithic
cn ip. They are designed to operate over a wide
range of supply voltages down to a single 5V logic
supply and ground. Further, they have higher
gain and lower input currents than devices like
the LM710. The uncommitted collector of the
output stage makes the LM 119 compatible with
RTL, DTL and TTL as well as capable of driving
lamps and relays at currents up to 25 mAo Outstanding features include:
features
•
•
•
•
Two independent comparators
Operates from a single 5V supply
Typically 80 ns response time at ±15V
Minimum fan-out of 2 each side
• Maximum input current of 1 /lA over temperature
• Inputs and outputs can be isolated from system
ground
• High common mode slew rate
Although designed primarily for applications requiring operation from digital logic supplies, the
LM119 is fully specified for power supplies up to
±15V. It features faster response than the LMlll
at the expense of higher power dissipation. However, the high speed, wide operating voltage range
and low package count make the LM 119 much
more versati Ie than older devices like the LM 711.
The LM219 is identical to the LM 119, except that
its performance is specified over a -25°C to 85°C
temperature range instead of -55°C to 125°C.

Note 1: For supply voltages less than ±15V the absolute maximum input voltage is equal to the supply voltage.
Note 2: The maximum junction temperature of the LM119 IS 150°C, while that of the LM219 IS 110°C. For operating at
elevated temperatures, devices in the TO·5 package must be derated based on a thermal resistance of 150°C/W, junction to
ambient, or 4SoCIW, junction to case. For the flat package, the derating IS based on a thermal resistance of 18SoCIW when
mounted on a 1/16-lnch-thick epoxy glass board with ten, 0.03-lnch·wide, 2·ounce copper conductors. The thermal reSistance
of the dual-in·line package IS 100D C/W, junction to ambient.
Note3: These speCificatiOns apply for Vs = ±15V and -5SoC ~ TA ~ 125°C, unless otherwise stated. With the LM219,
however, all temperature speCifications are limited to -2SoC ~ T A ~ 8S D C. The offset voltage, offset current and bias current
specifications apply for any supply voltage from a Single SV supply up to ±15V supplies.
Note 4: The offset voltages and offset currents given are the maximum values required to drive the output Within a volt of either supply With almA load. Thus, these par9meters define an error band and take into account the worst case effects of
voltage gain and input Impedance.
Note 5: The response time speCified IS for a 100 mV input step with 5 mV overdrive.

LM139/LM239/LM339 quad comparator
general description
The lM 139 series consists of four independent
voltage comparators which were designed specifi·
cally to operate from a single power supply over a
wide range of voltages. Operation from split power
supplies is also possible and the low power supply
current drain is independent of the magnitude of
the power supply voltage. These comparators also
have a unique characteristic in that the input
common·mode voltage range includes ground,
even though operated from a single power supply
voltage.
Application areas include limit comparators, simple
analog to digital converters; pulse, squarewave and
time delay generators; wide range VCO; MOS clock
timers; multivibrators and high voltage digital logic
gates. The lM 139 series was designed to directly
interface with TTL and CMOS. When operated
from both plus and minus power supplies, the
LM339 will directly interface with MOS logic where the low power drain of the lM339 is a
distinct advantage over standard comparators.

Note 1: For operating at high temperatures, the LM339 must be derated based on +125°e maximum junction temperature and a thermal
resistance of +17SoC/W whieh applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM239 and
LM139 must be derated based on a +150°C maximum junction temperature. The low bias dissipation and the ON-OFF characteristic of the
outputs keeps the chip dissipation very small (Pd < 100 mWI, provided the output transistors are allowed to saturate.
Note 2: Short circuits from the output to V+ ~an cause ~cessive heating and eventual destruction. The maximum output current is
approximately 20 rnA independent of the magnitude of V .
Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base
junction of the input PNP' transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action,
there is also I~eral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators
to go to the V voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive
and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3 Vec.
Note 4: These specifications apply for V+ = +5.0 Vec and -55°C $. TA :S +125°C, unless otherwise stated. With the LM239, all
temperature specifications are limited to -25D C $. TA $. +85°C and the LM339 temperature specifications are limited to oOe :S T A$. +70°C.
Note 5: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of
the state of the output so no loading change exists on the reference or input lines.
Note 6: The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper
end of the cammon-mode voltage range is v+ -1.5V, but either or both inputs can go to +30 Vec without damage.
Note 7: The response time specified is for a 100 mV input step with 5.0 mV overdrive. For larger overdrive signal5 300 ns can be obtained,
see typical performance characteristics section.
Note 8: The positive excursions of the input can exceed the power supply voltage level, and if the other input voltage remains within the
common-mode voltage range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3 VOC
(or 0.3 Vec below the magnitude of the negative power supply voltage, if used).

application hints
The LM139 is a high gain, wide bandwidth
device; which, like most comparators, can easily
oscillate if the output lead is inadvertently allowed
to capacitively couple to the inputs via stray
capacitance. This shows up only during the output
voltage transition intervals as the comparator changes states. Power supply bypassing is not required to solve this problem. Standard PC board
layout is helpful as it reduces stray input-output
coupling. Reducing the input resistors to <10 kn
reduces the feedback signal levels and finally,
adding even a small amount (1 to 10 mY) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are
not possible. Simply socketing the IIC and attaching resistors to the pins will cause input-output
oscillations during the small transition intervals
unless hysteresis is used. If the input signal is a
pulse waveform, with relatively fast rise and fall
times, hysteresis is not required.
All pins of any unused comparators should be
grounded.
The bias network of the LM 139 establ ishes a
drain current which is independent of the magnitude of the power supply voltage over the range of
from 2Voc to 30 Voc.
It is usually unnecessary to use a bypass capacitor
across the power supply line.
3-34
The differential input voltage may be larger than
V+ without damaging the device. Protection should
be provided to prevent the input voltages from
going negative more than -0.3 V DC (at 25°C). An
input clamp diode and input resistor can be used
as shown in the applications section.
The output of the LM139 is the uncommitted
collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output OR'ing function. An output "pullup" resistor can be connected to any available
power supply voltage within the permitted supply
voltage range and there is no restriction on this
voltage due to the magnitude of the voltage which
is applied to the V+ terminal of the LM139 package. The output can also be used as a simple SPST
switch to ground (when a "pull-up" resistor is not
used). The amount of current which the output
device can sink is limited by the drive available
(which is independent of V+) and the /3 of this
device. When the maximum current limit is
reached (approximately 16 mAl, the output transistor will come out of saturation and the output
voltage will rise very rapidly. The output saturation voltage is limited by the approximately 60n
rsat of the output transistor. The low offset voltage
of the output transistor (1 mV) allows the output
to clamp essentially to ground level for small load
currents.

The bias network of the LM139A establishes a

of from 2.0 Vec to 30 Vec.
It is usually unnecessary to use a bypass capacitor

The differential input voltage may be larger than
V+ without damaging the device (see Note 8).
Protection should be provided to prevent the input

output device can sink is limited by the drive
available (which is independent of V+) and the f3

is reached (approximately 16 mA), the output
transistor will come out of saturation and the
output voltage will rise very rapidly. The output
saturation voltage is limited by the approximately
60n rsa, of the output transistor. The low offset
voltage of the output transistor (1.0 mV) allows
the output to clamp essentially to ground level

LM710 voltage comparator
general description
saturating comparator applications. In fact, the low
stray and wiring capacitances that can be real ized
with monolithic construction make the device difficult to duplicate with discrete components operating at equivalent power levels.
The LM710 is useful as a pulse height discriminator, a voltage comparator in high-speed AID converters or a go, no-go detector in automatic test
equipment. It also has applications in digital systems as an adjustable-threshold line receiver or an
interface between logic types. In addition, the low
cost of the unit suggests it for applications replacing relatively simple discrete component circuitry.
The LM710 is a high-speed voltage comparator
intended for use as an accurate, low-level digital
level sensor or as a replacement for operational
amplifiers in comparator applications where speed
is of prime importance. The circuit has a differential input and a single-ended output, with saturated
output levels compatible with practically all types
of integrated logic.
The device is built on a single silicon chip which
insures low offset and thermal drift. The use of
a minimum number of stages along with minoritycarrier lifetime control (gold doping) makes the
circuit much faster than operational amplifiers in

LM711 dual comparator
general description
The LM711 contains two voltage comparators
with separate differential inputs, a common output and provision for strobing each side indepen·
dently. Similar to the LM710, the device features
low offset and thermal drift, a large input voltage
range, low power consumption, fast recovery from
large overloads and compatibility with mos) inte·
grated logic circuits.
With the addition of an external resistor network,
the LM711 can be used as a sense amplifier for
core memories. The input thresholding, combined
with the high gain of. the comparator, eliminates
many of the inaccuracies encountered with con·
ventional sense amplifier designs. Further, it has
the speed and accuracy needed for reliably detect·
ing the outputs of cores as small as 20 mils.
The LM711 is also useful in other applications
where a dual comparator with OR'ed outputs is
required, such as a double·ended limit detector. By
using common circuitry for both halves, the device
can provide high speed with lower power dissipa·
tion than two single comparators. The LM 711 is
available in either an 10·lead low profile TO·5
header or a 1/4" by 1/4" metal flat package.

Voltage Comparators/Buffers
LM2901 quad comparator
general description
The LM2901 consists of four independent voltage
compatators which were designed specifically for
automotive and industrial control systems. They
operate from a single power supply over a wide
range of voltages and the low power supply current
drain is independent ofthe magnitude of the power
supply voltage. These comparators also have a
unique characteristic in that the input commonmode voltage range includes ground, even though
operated from a single power supply voltage.
Application areas include limit comparators, simple
analog to digital converters; pulse, squarewave and
time delays generators; wide range VCO; MOS
clock timers; multivibrators and high voltage digital
logic gates. The LM2901 was designed to directly
interface with CMOS-where the low power drain
of the LM2901 is a large advantage over standard
comparator products.

Note 1: For operating at high temperatures, the LM2901 must be derat~d based on a +125° C maximum junction temperature
and a thermal resistance of 175°C/W which applies for the device soldered in a printed circuit board, operating in a still air am·
bient. The low bias dissipation and the ON·OFF characteristic of the outputs keeps the chip dissipation very small
"
(Pd < 100 mW), provided the output transistors are allowed to saturate.
Not; 2: Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output
current is approximately 20 mA independent of the magnitude of V+.
Note 3: The direction of the input current is out of the Ie due to the PNP input stage. This current is essentially constant,
independent of the state of the output so no loading change exists on the reference or input lines.
Note 4: The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than
0.3V. The upper end of the common-mode voltage range is V+ -1.SV, but either or both inputs can go to +30 VOC without
damage.
Note 5: The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be
obtained, see typical performance characteristics section.

application hints
The LM2901 is a high gain, wide bandwidth
device; which, like most comparators, can easily
oscillate if the output lead is inadvertently allowed
to capacitively couple to the inputs via stray
capacitance, This shows up only during the output voltage transition intervals as the comparator
changes states, Power supply bypassing is not required to solve this problem. Standard PC board
layout is helpful as it reduces stray input-output
coupling. Reducing the input resistors to <10 kn
reduces the feedback signal levels and finally,
adding even a small amount (1 to 10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback are
not pos~ible. Simply socketing the IC and attaching resistors to the pins will cause input-output
oscillations ·during the small transition intervals
unless hysteresis is used. If the input signal is a
pulse waveform, with relatively fast rise and fall
times, hysteresis is not required.
All pins of any unused comparators should be
grounded.
Thtt bias network of the LM2901 establishes a
drain current which is independent of the magnitude 'of the power supply voltage over the range of
from 2Voc to 30 Voc.
It is usually unnecessary to use a bypass capacitor
across the power supply line.
3-62
The differential input voltage may be larger than
V+ without damaging the device. Protection should
be provided to prevent the input voltages from
going negative more than -0.3 VDC (at 25°C). An
input clamp diode can be used as shown in the
applications section.
The output of the LM2901 is the uncommitted
collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output OR'ing function. An output pullup resistor can be connected to any available
power supply voltage within the permitted supply
voltage range and there is no restriction on this
voltage due to the magnitude of the voltage which
is applied to the V+ terminal of the LM2901 package. The output can also be used as a simple SPST
switch to ground (when a pull-up resistor is not
used). The amount of current which the output
device can sink is 'Iimited by the drive available
(which is independent of V+) and the (3 of this
device. When the maximum current limit is
reached (approximately 16 mA), the output transistor will come out of saturation and the output
voltage will rise very rapidly. The output saturation voltage is limited by the approximately 600
rsat of the output transistor. The low offset voltage
of the output transistor (1 m V) allows the output
to clamp essentially to ground level for small load
currents.

Note 1: FDr Dperating at high temperatures, the LM3302 must be derated based on +125' C maximum junction temperature and a thermal
resistance of 175'C/W which applies for the device sDldered in a printed circuit board, operating in a still air ambient.
Note 2: Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately
20 mA independent of the magnitude Df V+_
Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of
the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition tD this diode action, there is also lateral
NPN parasitic transistor action on the Ie chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level
(or to ground for a large Dverdrive) fDr the time duratiDn that an input is driven negative_ This is not destructive and nDrmal output states will
re-establish when the input vDltage, which was negative, again returns to a value greater than -0_3 VOC.
Note 4: These specifications apply for V+ = +5_0 VOC and -40·C:5 TA :5 +85'C_
Note 5: The directiDn of the input current is out of the IC due tD the PNP input stage_ This current is essentially cDnstant, independent of the state
of the output so no loading change exists on the reference or input lines.
Note 6: The input common-mode vDltage or either input signal voltage should not be allowad to go negative by more then 0_3V_ The upper end of

typical performance characteristics section.
Note 8: The pDsitive excursions Df the inputs can exceed the power supply voltage level and if the other input voltage remains within the commonmode vDltage range, the comparator will provide a proper output state_ The low input vDltage state must not be less than -0.3 VOC (or 0.3 VOC
below the magnitude of the negative power supply voltage, if used).

small amount (1 to 10 mV) of positive feedback
(hysteresis) causes such a rapid transition that oscillations due to stray feedback are not possible. Simply
socketing the IIC and attaching resistors to the pins will
cause input-output oscillations during the small transition intervals unless hysteresis is used. If the input
signal is a pulse waveform, with relatively fast rise and
fall times, hysteresis is not required,
All pins of any unused comparators should be grounded.
The bias netwo'rk of the LM3302 establishes a drain
current which is independent of the magnitude of the
power supply voltage over the range of from 2 Vee
to 28 Vee.
It is usually unnecessary to use a bypass capacitor across
the power supply line.
3·68
The differential input voltage may be larger than V+
without damaging the device. Protection should be provided to prevent the input voltages from going negative
more than -Q.3 Vee (at 25°C). An input clamp diode
and input resistor can be used as shown in the applications section.
The output of the LM3302 ,is the uncommitted collector
of a grounded·emitter NPN output ,transistor. Many
collectors can be tied together to provide an output
OR'ing function. An output "pull-up" resistor can be
connected to any available power supply voltage within
the permitted supply voltage range and there is no
restriction on this voltage due to the magnitude of the
voltage which is applied to the V+ terminal of the
LM3302 package. The output can also be used as a
simple SPST switch to ground (when a "pull-up" resistor
is not used). The amount of current which the output
device can sink is limited by the drive available (which
is indepeJident of V+) and the ~ of this device. When the
maximum current limit is reached (approximately 16
rnA), the output transistor will come out of saturation
and the output voltage will rise very rapidly. The output
saturation voltage ~s limited by the approximately 60n
rsat of the output transistor. The low offset voltage of
the output transistor (1 mV) allows the output to clamp
essentially to ground level for small load currents.

general description
The LM 122 is a precision timer that offers great
versatility with high accuracy. It operates off
unregulated supplies from 4.5V to 40V while
maintaining constant timing periods from microseconds to hours. Internal logic and regulator cir·
cuits complement the basic timing function enabling the LM122 to operate in many different
applications with a minimum of external com·
ponents.
The output of the timer is a floating transistor
with built in current limiting. It can drive either
ground referred or supply referred loads up to 40V
and 50 mAo The floating nature of this output
makes it ideal for interfacing, lamp or relay driving, and signal conditioning where an open colIp.ctor or emitter is required. A "logic reverse" cir·
cuit can be programmed by the user to make the
output transistor either "on" or "off" during the
timing period.
The trigger input to the LM 122 has a threshold of
1.6V independent of supply voltage, but it is fully
protected against inputs as high as ±40V - even
when using a 5V supply. The circuitry reacts only
to the rising edge of the trigger signal, and is
immune to any trigger voltage during the timing
periods.

with an external source through the VADJ pin.
Timing ratios of 50: 1 can be easily achieved.
W
N
N
The comparator used in the LM 122 utilizes high
gain PNP input transistors to achieve 300 pA typical input bias current over a common mode range
of OV to 3,<. A boost terminal, allows the user to
increase comparator operating current for timing
periods less than 1 ms. This lets the timer operate over a 3Jls to multi-hour timing range with
excellent repeatabil ity.
The LM122 operates over a temperature range of
-55°e to +125°e. An electrically identical LM222
is specified from -25°e to +85°e. The timer is
available in TO-5, flat package, and dual-in-line
packages.

• Operates from 4.5V to 40V supplies
An internal 3.15V regulator is included in the
timer to reject supply voltage changes and to pro·
vide the user with a convenient reference for applications other than a basic timer. External loads up
to 5 mA can be driven by the regulator. An internal 2V divider between the reference and ground
sets the timing period to 1 Re. The timing period
can be voltage controlled by driving this divider

general description
The LM555 is a highly stable device for generating
accurate time delays or oscillation. Additional terminals
are provided for triggering or resetting if desired. In the
time delay mode of operation, the time is precisely con·
trolled by one external resistor and capacitor. For astable
operation as an oscillator, the free running frequency and
duty cycle are accurately controlled with two external
resistors and one capacitor. The circuit may be triggered
and reset on falling waveforms, and the output circuit
can source or sink up to 200 mA or drive TTL circuits.

Note 1: For operating at elevated temperatures the device must be derated based on a +150°C maximum junction temperature and a thermal
resistance of +45°elW junction to case for TO·5 and +150o elW junction to ambient for both packages.
Note 2: Supply current when output high typie~IIY 1 mA less at Vee = 5V.
Note 3: Tested at Vee = 5V and Vee = 15V.
Note 4: .This will determine the maximum value of RA + RS for 15V operation. The maximum total (RA + RS) is 20 MO.
Note 5: No protection against excessive pin 7 current is necessary providing the package dissipation rating will not be exceeded.

In this mode of operation, the timer functions as a
one-shot (Figure 1). The external capacitor is initially
held discharged by a transistor inside the timer. Upon application of a negative trigger pulse of less than 1/3 Vcc
to pin 2, the flip·flop is set which both releases the short
circuit across the capacitor and drives the output high.

The voltage across the capacitor then increases exponentially for a period of t = 1.1 RAe, at the end of which
time the voltage equals 2/3 Vee. The comparator then
resets the flip·flop which in turn discharges the capacitor
and drives the output to its low state. Figure 2 shows
the waveforms generated in thi~ mode of operation.
Since the charge and the threshold level of the comparator are both directly proportional to supply voltage,
the timing internal is independent of supply.

During the timing cycle when the output is high, the
further application of a trigger pulse will not effect the
circuit. However the circuit can be reset during this time
by the application of a negative pulse to the reset
terminal (pin 4). The output will then remain in the low

FREQUENCY DIVIDER
This application uses the· timer connected for astable
operation, as in Figure 10, with a modulating signal
again applied to the control voltage terminal. The pulse
position varies with the modulating signal, since the
threshold voltage and hence the time delay is varied.
Figure 11 shows the waveforms generated for a triangle
wave modulation signal.
The monostable circuit of Figure 1 can be used as a
frequency divider by adjusting the length of the timing
cycle. Figure 7 shows the waveforms generated in a

ADDITIONAL INFORMATION
Adequate power supply bypassing is necessary to protect
associated circuitry. Minimum recommended is O.l~F in
parallel with l~F electrolytic.
Lower comparator storage time can be as long as 10~s
when pin 2 is driven fully to ground for triggering. This
limits the monostable pulse width to 10~s minimum.
Delay time reset to output is 0.47~s typical. Minimum
reset pu Ise width must be 0.3/ls, typical.
Pin 7 current switches within 30 ns of the output
(pin 3) voltage.

LM2905/LM3905 precision timer
general description
The LM3905 is a precision timer that offers great
versatility with high accuracy. It operates off
unregulated supplies from 4.5V to 40V while
maintaining constant timing periods from milliseconds to hours. Internal logic and regulator circuits complement the basic timing function enabling the LM3905 to operate in many different
applications with a minimum of external components.
The output of the timer is a floating transistor
with built in current limiting. It can drive either
ground referred or supply referred loads up to 40V
and 50 mAo The floating nature of this output
makes it ideal for interfacing, lamp or relay driving, and signal conditioning where an open col·
Ip.ctor or emitter is required. A "logic reverse" cir·
cuit can be programmed by the user to make the
output transistor either "on" or "off" during the
timing period.
The trigger input to the LM3905 has a threshold of
1.6V independent of supply voltage, but it is fully
protected against inputs as high as ±40V - even
when using a 5V supply. The circuitry reacts only
to the rising edge of the trigger signal, and is
immune to any trigger voltage during the timing
periods.
typical applications
CD
o
An internal 3.15V regulator is included in the
timer to reject supply voltage changes and to provide the user with a convenient reference for applications other than a basic timer. External loads up
to 5 mA can be driven by the regulator. An internal 2V divider between the reference and ground
sets the timing period to 1 RG.
U'I
The comparator used in the LM3905 utilizes high
gain PNP input transistors to achieve 300 pA typical input bias current over a common mode range
of OV to 3V.

Note 1: Continuous output shorts are not allowed. Short circuit duration at ambient temperatures of 40°C may be
calculated from t = 50/VeE seconds, where VeE is the collector to emitter voltage across the output transistor during the
short.
Not. 2: Specifications include the temperature range -40°C ~ TA ~ +8SoC for the LM290S and O"c ~ TA ~ +70°C for the
LM390S unless otherwise noted.
Not. 3: Output pulse width can be calculated from the following equation: t = (R t )(C r l[l - 2(0.632 - r) - VCIVREFl where
r is timing ratio 'and Vc is capacitor saturation voltage. This reduces to t = (Rt)(Ct) for all but the most critical applications.
Note 4: Sign reversal may occur at high temperatures (

operating notes
Voltage gain is continuously variable from a maximum value, dependent upon supply voltage, to a
minimum value, by application of a DC control
voltage at Pin 3 or 4. DC output voltage is substantially independent of gain· changes, provided
that differential DC input voltage is minimized, so
that direct-coupled or fast gain-control operation
is possible with minimum disturbance of succeeding ampl ifiers.
Input characteristics are similar to those of an
operational amplifier, with common-mode input
range extending from +4.5 volts up to and including the positive supply voltage. Lowest distortion
occurs at input levels of 20 mV POp or less. Outputs of several ampl ifiers, wh ich wi II have qu iescent DC levels approximately half of the positive
5-2
supply, may be directly connected together in
multi-channel summing systems, without damage.
Emitter-follower control. inputs, Pins 3 and 4, may
be used as positive peak detectors by connecting a
smoothing capacitor at Pin 2, in AGC applications.
A sensitive squelch detector, independent of the
amplifier's gain, provides fast-attack, slow release
control at Pin 6, with threshold set by an external
resistance from Pin 7 to ground. Injecting a portion of the control voltage at Pin 6 into this threshold results in a hys~eresis, reducing response to
erratic inputs. Since threshold is dependent on DC
levels, differential DC input voltage should be held
constant for squelch operation.

cascode configuration
The common-emitter, common-base, or cascade,
configuration is useful as a tuned R F or I F amplifier to 250 MHz. Two common-base stages are
formed by the differential pair, Ql and Q2, which
may be used as a gain control system by applying
a differential gain oontrol voltage between pins 1
and 7. With Ql cut off, maximum gain is obtained,
being reduced as Ql is progressively turned on and
Q2 turned off. The input common-emitter transistor presents a nearly constant input admittance as
AGC is applied.
Pin 3 may be used as the DC reference for the AGC
input, to assure adequate bias voltage for the collector of Q3. Where large AGC voltages are used, an
external resistive divider, from pin 3 to 1 to the
AGC voltage may be used to optimize the DC AGC
requirements. VAGC is defined as the voltage between pin 1 and 7.
At some frequencies, bypassing may be required at
pins 1, 3, 4 or the Vee connection.
DC input bias is obtained through the input inductor from the bias chain, pin,4.

emitter coupled configuration
The common-collector, common-base, or emittercoupled configuration is useful as a symmetrically non-saturated limiting R F or IF amplifier to
150 MHz. Basically a differential amplifier, this
configuration is especially suited to FM IF strips
using 'conventional interstage tuning_ While available gain is lower and noise figure higher than the
cascode, emitter coupled operation may be considered wherever fast recovery from large-signal overdrive or excellent AM rejection is required_
nal, and is equally divided when no signal is present,
assuring inherently symmetrical operation_ DC bias
for pin 7 is obtained from the divider chain, and
through the input inductor, the same bias is applied

For non-saturated operation, the output load must
be chosen so that the collector voltage of the output transistor is higher than the DC reference voltage, with all source current shunted into the output, for the particular bias levels used_
Q3 is used as a current source, obtaining its bias
from the diode chain_ Current available from 03 is
shunted through 01 or 02, depending on input sig-

APPLICATION HINTS
The LM273/LM373 and LM274/LM374 devices
have been designed for stability and minimum
usage of external components, while at the same
time offering wide versatility through access to
inputs and outputs of nearly every major functional block of the device. This makes possible the
detection of AM, FM,and SSB signals with a single
device with a minimum of circuitry switching.
Experience has shown that for optimum performance of the multiple mode IF strip, the following
suggestions should be noted.
First, as with any radio frequency gain device,
proper layout and minimum lead length should be
observed. The first gain block, Pin 2 to Pin g, shows
a typical gain of 32 dB and the second gain
block, Pin 4 to Pin 7, shows a typical gain of 37
dB so it is clear why any stray coupling or long
leads should be kept clear from any of the gain
input pins. Despite it's high gain, however, the
device does not require any shielding between
stages. Construction on a copperclad printed circuit type board is more than adequate. It should
also be observed that good power supply bypassing directly at Pin 10 and DC feedback bypassing
at Pin 3 is always necessary.
The devices can be wide-band coupled to provide
video gain response up to approximately 50 MHz.
For AM operation, however, it is much more desirable to limit the I F bandwidths. This will greatly
increase both input sensitivity and AGC figure of
merit by preventing the device from AGCing on
wide band detected noise. There are two ways of
accomplishing this. One is to insert filtering from
the first gain block to the second, Pin 9 to Pin 4,
but the most effective way is to AC couple an L-C
tank from the input of the active peak detector to
ground. A lossy filter from Pin g to Pin 4 should be
avoided as this will greatly reduce the audio output
and AGC figure merit. In addition the tank on Pin
7 should have high enough Q to limit noise yet
low enough to pass the full IF signal. It should
also have a high enough impedance (>5k) to avoid
affecting the gain of that stage. Proper audio output is attained by a small capacitor at Pin 8 to
peak detect the R F envelope, followed by a series
RC roll off to shape the audio response. Here
again excessive loading will reduce available output. There is a trade off available between audio
level out and AGC range so the feedback resistor
from Pin 8 to the AGC feedback, Pin 1, should be
adjusted to give the desired results. Pin 1 must
5-19
be filtered well with approximately 15 J.LF capaci'
tor or larger to prevent any AC variation from
causing erratic AGC action.
place symmetrically around the resonant frequency
of the tank. Since the audio output for FM is at
Pin 7, it should be RF bypassed along with audio
roll off and de·emphasis.
For proper FM operation, the input level needs to
be larger, on the order of 1 mV to give full limiting
which is necessary for good AM rejection. Here
again low loss coupling from Pin 9 to Pin 4 is
desired. The phase shift network on 'Pin 6 should
be shielded to prevent any extraneous RF pickup
or radiation. Also the Q of the network should be
adjusted to give the proper bandwidth for the
type of signal to be detected, whether wide band or
narrowband FM. Obviously, it should be tuned
to the same center. frequency as the I F input and
the Pin 9 to Pin 4 filtering so that detection takes
For SSB operation, the devices operate almost
the same as in the AM mode, with the excep·
tion that the product detector which was un·
balanced and used as a simple gain stage for
AM is now balanced and used for detection. The
local oscillator signal is fed into Pin 6 at an opti·
mum level around 60 mVrms. For better AGC, a
capacitor may be added to Pin 8 in addition to
the one already at Pin 1 to provide even more
filtering for AGC feedback voltage. The output
level and AGC figure of merit is still adjusted by
the feedback resistors from Pin 8 to Pin 1.

LM380 audio power amplifier
general description
The LM3BO is a power audio amplifier for con·
sumer application. In order to hold system cost to
a minimum, gain is internally fixed at 34 dB. A
unique input stage allows inputs to be grou nd
referenced. The output is automatically self ent·
ering to one half the supply voltage.
The output is short circuit proof with internal'
thermal limiting. The package outline is standard
dual·in·line. A copper lead frame is used with the
center three pins on either side comprising a heat
sink. This makes the device easy to use in standard
p·c layout. A mini dual·in·line package version
with reduced power capability also available.
Uses include simple phonograph amplifiers, inter·
coms, line drivers, teaching machine outputs,
alarms, ultrasonic drivers, TV sound systems, AM·
FM radio, small servo drivers, power converters,etc.

LM3811LM381A low noise dual preamplifier
general description
,additional external compensation for narrow band
applications.
The LM381/LM381A is a dual preamplifier for
the amplication of low level signals in applications
requiring optimum noise performance. Each of the
two amplifiers is completely independent, with
individual internal power supply decoupler·
regulator, providing 120 dB supply rejection and
60 dB channel separation. Other outstanding
features include high gain (112 dB), large output
voltage swing (Vee -2V) p.p, and wide power
bandwidth (75 kHz, 20Vp.p). The LM381/LM381A
operates from a single supply across the wide range
of 9 to 40V.

LM386 low voltage audio power amplifier
general description
The LM386 is a power amplifier designed for use in low
voltage consumer applications. The gain is internally
set to 20 to keep external part count low, but the
addition of an external resistor and capacitor between
pins 1 and 8 will increase the gain to any value up
to 200.
The inputs are ground referenced while the output is
automatically biased to one half the supply voltage. The
quiescent power drain is only 18 milliwatts when oper·
ating from a 6 volt supply, making the LM386 ideal
for battery operation.

Note 2: If oscillation exists under some load conditions, add 10n and O.05~F series network from pin 5 to ground.
application hints
GAIN CONTROL
INPUT BIASING
To make the LM386 a more versatile amplifier, two pins
(1 and 8) are provided for gain control. With pins 1 and
8 open the 1.35 k£1 resistor sets the gain at 20 (26 dB).
If a capacitor is put from pin 1 to 8, bypassing the
1.35 k£1 resistor, the gain will go up to 200 (46 dB). If
a resistor is placed in series with the capacitor, the gain
can be set to any value from 20 to 200. Gain control can
also be done by capacitively coupling a resistor (or FET)
from pin 1 to ground.
The schematic shows that both inputs "are biased to
ground with a 50 k£1 resistor. The base current of the
input transistors is about 250 nA, so the inputs are at
about 12.5 mV when left open. If the dc source resistance driving the LM386 is higher than 250 k£1 it will
contribute very little additional offset (about 2,5 mV at
the input, 50 mV at the output), If the dc source
resistance is less than 10 k£1, then shorting the unused
input to ground will keep the offset low (about 2.5 mV
at the input, 50 mV at the output). For dc source
resistances between these values we can eliminate excess
offset by putting a resistor from the unused input to
ground, equal in value to the dc source resistance, Of
course all offset problems are eliminated if the input is
capacitively coupled.
Additional external components can be placed in parallel
with the internal feedback resistors to tailor the gain and
frequency response for individual applications. For example, we can compensate poor speaker bass response
by frequency shaping the feedback path. This is done
with a series RC from pin 1 to 5 (paralleling the internal
15k£1 resistor). For 6 dB effectivebass boost: R ~ 15 k£1,
the lowest value for good stable operation is R = 10 k£1
if pin 8 is open. If pins 1 and 8 are bypassed then R as
low as 2 k£1 can be used. This restriction is because the
amplifier is only compensated for closed-loop gains
greater than 9.
When using the LM386 with higher gains (bypassing
the 1.35 k£1 resistor between pins 1 and 8) it is necessary
to bypass the unused input, preventing degradation of
gain and possible instabilities. This is done with a 0.1/lF
capacitor or a short to ground depending on the dc
source resistance on the driven input.

LM565/LM565C phase locked loop
The LM565 and LM565C are general pu rpose phase
locked loops containing a stable, highly linear voltage controlled oscillator for low distortion FM
demodulation, and a double balanced phase detector with good carrier su ppression_ The VCO frequency is set with an external resistor and capacitor, and a tuning range of 10: 1 can be obtained
with the same capacitor_ The characteristics of the
closed loop system-bandwidth, response speed,
capture and pull in range-may be adjusted over a
wide range with an external resistor and capacitor_
The loop may be broken between the VCO and
the phase detector for insertion of a digital frequency divider to obtain frequency multiplication_

For narrow band applications where a narrow noise
bandwidth is desired, such as applications involving
tracking a slowly varying carrier, a lead lag filter
should be used. In general, if 1/R 1 C1 < KoKd,
the damping factor for the loop becomes quite
small resulting in large overshoot and possible
instability in the transient response of the loop.
In this case, the natural frequency of the loop
may be found from

Loop gain may be reduced by connecting a resistor
between pins 6 and 7 ; this reduces the load imped·

general description
w
The LM1304, LM1305, LM1307 and LM1307E are
designed to derive the left and right channel audio
information from the detected composite stereo
signal. The LM1304 eliminates the need for an
external stereo-channel separation control. The
LM1305 is similar to the LM1304 but permits the
use of an external stereo-channel separation control
for maximum separation. The LM 1307 is also
similar to the LM 1304 but does riot have the audio
mute control, or the stereo/mono switch. The
LM1307E is similar to the LM1307 but has the
o
m
option of emitter-follower output drivers for buffers or high current applications.

LM1310 phase locked loop FM stereo demodulator
general description
features
The LM1310 is an integrated FM stereo demodu·
lator using phase locked loop techniques to regen·
erate the 38 kHz subcarrier. A second version
also available is the LM1800 (see separate data
sheet) which adds superb power supply rejection
and buffered (emitter follower) Otltputs to the
basic phase locked decoder circuit. The features
available in these integrated circuits make possible
a system delivering high fidelity sound within the
cost restraints of inexpensive stereo receivers.

SSB Product Detector
This figure shows the LM1596 used as a single sideband (SSB) suppressed carrier demodulator (product detector). The
carrier signal is applied to the carrier input port with sufficient amplitude for switching operation. A carrier input level
of 300 mVrm. is optimum. The compo.ite 5SB .igna' is applied to the .igna' input port with an amplitude of 5.0 to
500 mVrms. All output signal components except the desired demodulated audio are filtered out, so that an offset
adjustment is not required. This circuit may also be used as an AM detector by applying composite and carrier signals
in the same manner as described for product detector operation.

Broadband Frequency Doubler
The frequency doubler circuit shown will double low·level signals with low distortion. The value of C should be chosen
for low reactance at the operating frequency.
Signal level at the carrier input must be less than 25 mV peak 10 maintain operation in the linear region of the switching
differential amplifier. Levels to 50 mV peak may be used with some distortion of the output waveform. If a larger input
signal is available a resistive divider may be used at the carrier input, with full signal applied to the signal input.

LM1808 monolithic TV sound system
general description
features
The LM1808 2 watt sound IF circuit is designed for
television and related applications. The circuit is com·
prised of two independent functions: a sound I F and an
audio power amplifier. The sound I F portion of the
circuit utilizes circuitry similar to the LM3065. An
improved volume control circuit is included, however,
so that recovered audio is a linear function of the
resistance of the control potentiometer. Audio power
amplification is accomplished with circuitry similar to
the popular LM380 audio power amplifier, featuring
both short circuit and thermal protection.

LM1829 TV chroma processor
general description
The LM1829 is a monolithic integrated circuit which
provides complete color TV chroma signal processing
except for tint control and chroma demodulation. Subcarrier regeneration is performed by a phase locked loop
utilizing sample-and-hold techniques. A crystal controlled voltage controlled oscillator (VCO) provides
stable output with only an initial trimmer capacitor
adjustment.
The LM1829 may be used with the LM3067 chroma
demodulator for a complete color processing system.
The chroma section uses a synchronous chroma burst
level detector in an automatic chrominance control
(ACC) loop with color killer. The burst signal is gated
out of the chroma signal and the chroma output is then
determined by a manual dc saturation control. In addition, an overload detector corrects for variations in
burst-to-chrominance ratio.

LM3065 television sound system
general description
The LM3065 is a monolithic integrated circuit
television sound system that requires a minimum
of external components for operation_ It includes
three stages of IF limiting, an FM detector, an
electronic attenuator or volume control, an audio
amplifier-driver, and a temperature stable regulated power supply_ Volume control is accomplished by varying bias leveis of the electronic
attenuator with a potentiometer between pin 6
and ground_ Because no audio signal is present in
this control, hum and noise pickup are easily filtered_ Unshielded wire may be used for volume
control. Features include:
• Electronic attenuator: replaces conventional ac
volume control
• Volume reduction range: >60 dB
• Sensitivity: 3 dB limiting voltage-200 p.V typically
• High stability
• Low harmonic distortion
• Audio drive capability: 6 mA Pop
• Undistorted audio output voltage: 7V Pop
• Differential peak detector
• Simple detector alignment: one coil
• Internal zener diode regulator
• Excellent AM rejection-50 dB typ_

LM3067 chroma demodulator
general description
The LM3067 is a monolithic integrated circuit
designed primarily for color signal demodulation
in color television receivers. A DC tint control
is also included. The reference subcarrier and
chroma signals are applied and the three de·
modulated R-Y, G-Y, B-Y color difference
signals are delivered with close DC balance and
proper amplitude ratios. The tint control achieves
a 100°+ phase adjustment by means of a customer·
operated DC control. A limiting amplifier and phase
shift network provide constant amplitude carriers
phase shifted 76° which then feed demodulator
drive amplifiers. The demodulators consist of two
sets of balanced detectors which receive the
reference subcarrier and chroma signal. The chroma
signal is then demodulated, matrixed, and DC
shifted in voltage. The LM3067 and LM3066
Chroma Signal Processor constitute a complete
chroma system for color television receivers.

• Balanced chroma demodulators
• DC tint control
• Color difference matrix
• Low output impedance drivers for direct
coupling

LM3071 television chroma IF amplifier
general description
The LM3071 is a two stage chroma IF amplifier
on a single silicon chip encapsulated in a 14 lead
molded·Dual·ln·Line Package. The first stage is an
automatic gain controlled amplifier, and its output
from Pin 6 is used to drive the ACC detector of
the LM3070 or an equivalent circuit. The output
from the ACC detector is applied to Pins 1 and 14
to control the gain of the stage. The second ampli·
fier stage is driven from the output of the first at
Pin 7, and the gain is controlled by adjusting the
DC voltage at Pin 10. The output from Pin 9
supplies the chroma drive signal to the chroma
demodulator circuit. In addition, the second stage
may be gated "OFF" to provide "color killing"
action in the absence of color signal at the output
of the first stage. The killer trip point is adjusted
externally.
features
• Very effective gain control of both stages
• Good signal handling capability
• Excellent gain stability with temperature and
supply voltage variations
•
Low distortion

general description
These devices contain a pair of junction-isolated
NPN transistors fabricated on a single silicon substrate. This monolithic structure makes possible
extremely·tight parameter matching at low cost.
Further, advanced processing techniques yield exceptionally high current gains at low collector cur-
• High current gain-500 minimum at 10 IlA
• Tight beta match-1 0% maximum
• High breakdown voltage-to GOV
• Matching guaranteed over a OV to 45V collectorbase voltage range.
rents, virtual elimination of "popcorn noise," low
leakages and improved long·term stability. Some
of the major feature$ of these pairs are indicated
by the following specifications:
Although designed primarily for high breakdown
voltage and exceptional dc characteristics, these
transistors have surprisingly good high-frequency
performance. The gain-bandwidth product is
450 MHz with 1 rnA collector current and 5V
collector-base voltage and 22 MHz with 10 IlA collector current. Collector-base capacitance is only
1.3pFat5V.

LM195/LM295/LM395 power transistors
general description
The LM195/LM295/LM395 are fast, monolithic
power transistors with complete overload protection_ These devices, which act as high gain power
transistors, have included on the chip, current
limiting, power limiting, and thermal overload
protection making them virtually impossible to
destroy from any type of overload_ In the standard
TO-3 transistor power package, the LM 195 will
deliver load currents in excess of 1_0A and can
switch 40V in 500 ns_
The inclusion of thermal limiting, a feature not
easily available in discrete designs, provides virtually
absolute protection against overload_ Excessive
power dissipation or inadequate heat sinking
causes the thermal limiting circuitry to turn off
the device preventing excessive heating_

Greater than 1_0A output current

Base can be driven up to 40V without damage
Directly interfaces with CMOS or TTL
The LM 195 offers a significant increase in reliability a; well as simplifying power circuitry_ In some
applications, where protection is unusually difficult,
such as switching regulators, lamp or solenoid
drivers where normal power dissipation is low, the
LM195 is especially advantageous_
"
The LM195 is easy to use and only a few precautions need be observed. Excessive collector to
emitter voltage can destroy the LM 195 as with
any power transistor. When the device is used as
an emitter follower with low source impedance, it
is necessary to insert a 5.0k resistor in series with
the base lead to prevent possible emitter follower
oscillations. Although the device is usually stable
as an emitter follower, the resistor eliminates the
possibility of trouble without degrading performance. Finally, since it has good high frequency
response, supply by passing is recommended.
The LM195/LM295/LM395 are available in standard TO-3 power packages and solid Kovar TO-5.
The LM195 is rated for operation from -55°C to
+150°C, the LM295 from -25°C to +150°C and
the LM395 from OoC to +125°C.

general description
The LM3026 and LM3054 each consists of two
independent differential ampl ifiers with associated
constant-current transistors on a common monolithic substrate_ The six NPN transistors which
comprise the amplifiers are general purpose devices
which exhibit low llf noise and a value of fT in
excess of 300 MHz_ These features make the
LM3026 and LM3054 useful from DC to 120 MHz_
Bias and load resistors have been omitted to provide maximum application flexibility_
The monolithic construction of the LM3026 and
LM3054 provides close electrical and thermal
matching of the amplifiers_ This feature makes
these devices particularly useful in dual channel
applications where matched performance of the
two channels is required_

Configuration: (For Each Amplifier)
Note: The collector of each transistor of the LM3026 and LM3054 is isolated from the substrate by an integral diode. The
substrate must be connected to a voltage which is more negative than any collector voltage in order to maintain isolation
between transistors and provide for normal transistor action. The substrate should be maintained at signal (AC) ground by
means of a suitable grounding capacitor, to avoid undesired coupling between transistors.

Note 1: In the LM3026 terminal NO.9 is connected to the emitter of Q4, the reference substrate, and the case; therefore, the
case should not be grounded. Two terminal 9 columns LM3026 appear in the voltage rating chart because it is a composite
chart for both the LM3026 and the LM3054. Wherever an asterisk is shown in one column 9 and a rating is shown in the other
column 9, the asterisk should be ignored.
Nota 2: Terminal No.1 0 of LM3054 is not used.
t LM3026; corresponding terminals for LM3054 are vertical terminal 2 and horizontal terminal 4.
*Voltages are not normally applied between these terminals. Voltages appearing between these terminals will be safe if the
specified limits between all ather terminals are not exceeded.

Transistor/D iode Arrays
LM3039 diode array
general description
The LM3039 consists of six ultra-fast, low capacitance silicon diodes on a common monolithic substrate_ Five of the diodes are independently accessible, the sixth shares a common terminal with the
substrate. Integrated circuit construction assures
excellent static and dynamic matching of the
diodes, making the array extremely useful for a
wide variety of applications in communication and
switching systems.

• Balanced modulators or demodulators
•

•
High speed diode gates
• Analog switches
features
• Excellent reverse recovery time
• Matched monolithic
construction
For applications such as balanced modulators or
ring modulators where capacitive balance is important, the substrate should be returned to a DC
potential which is significantly more negative
(with respect to the active diodes) than the peak
signal applied.

general description
features
The LM3045, LM3046, and LM3086 each consist
of five general purpose silicon NPN transistors on
a common monolithic substrate. Two of the tran·
sistors are internally connected to form a differ·
entially·connected pair. The transistors are well
suited to a wide variety of applications in low
power system in the DC through VH F range. They
may be used as discrete transistors in conventional
circuits however, in addition, they provide the
very significant inherent integrated circuit advan·
tages of close electrical and thermal matchin~. The
LM3045 is supplied in a 14·lead cavity dual·in·line
package rated for operation over the full military
temperature range. The LM3046 and LM3086 are
electrically identical to the LM3045 but are
supplied in a 14·lead molded dual-in-line package
for applications requiring only a limited temperature range.

ADMITTANCE CHARACTERISTICS
Note 1: Derate at 5 mWt C for T A > +85° C.
Note 2: The collector of each transistor is isolated from the substrate by an integral diode. The substrate must be c"nnected to a vortage which is
more negative than any collector voltage in order to maintain isolation between transistors and provide normal transistor action. To avoid un~
desired coupling betmen transistors, the substrate terminal should be maintained at either de or signal (ae) ground. A suitable bypass capacitor can
be used to establish a signal ground.
Note 3: If the transistors are forced into zener breakdown (V (BRJEBOJ degradation of forward transfer current ratio (hFE) can occur.
Note 4: See curve.

The LM3145/LM3145A and LM3146/LM3146A each
consist of five high voltage general purpose silicon NPN
transistors on a common monolithic substrate. Two of
the transistors are internallY connected to form a differ·
entially-connected pair. The transistors are well suited to

Note 1: The collector of each transistor is isolated from the substrate by an integral diode. The substrate must be connected to a voltage which is
more negative than any collector voltage in order to maintain isolation between transitors and provide normal transistor action. To avoid undesired
coupling between transistors, the substrate terminal should be maintained at either de or signal (ae) ground. A suitable bypass capacitor can be
used to establish a signal ground.
Not.2: If the transistors are forced into zener breakdown (V (BR)EBO), degradation of forward transfer current ratio (hFE) can occur.

The graph shows the boundary conditions which
must be used for proper operation of the unit.
The range of operation for power supply V- is
shown on the X axis, It must be between -25V
and -avo The allowable range for power supply
v+ is governed by supply V-. With a value chosen
for V-, V+ may be selected as any value along a
vertical line passing through the V- value and
terminated by the boundaries of the operating
region, A voltage difference between power supplies of at least 5V should be maintained for
adequate signal swing.

1. INPUT LOGIC COMPATIBILITY
A. Voltage Considerations
o
::J:
In general, the AH0100 series is compatible with
most DTL, TTL, and RTL logic families. The ONinput threshold is determined by the V BE of the
input transistor plus the Vf of the diode in the
emitter leg, plus I x R1, plus V R. At room
temperature and V R = OV, the nominal ON threshold is:0.7V+0.7V+0.2V,= 1.6V.Over temperature
and manufacturing tolerances, the threshold may
be as high as 2.SV and as low as 0.8V. The rules
for proper operation are:
2.SV). The V R terminal can be driven from most
TTL and DTL gates.
3. DIFFERENTIAL INPUT CONSIDERATIONS
The differential switch driver is essentially a differential amplifier. The input requirements for proper
operation are:
)V IN1 - V IN2 1:::: 0.3V
2.S ~ (V IN1 or VIN2 ) - V R ~ SV
The differential driver may be furnished by a DC
level as shown below. The level may be derived
from a voltage divider to V+ or the 5V Vcc of
the DTL logic. In order to assure proper operation,
the divider should be "stiff" with respect to IIN2'
Bypassing R 1 with a 0.1 p.F disc capacitor will
prevent degradation of tON and to FF.

where:
Rp = value of the pull-up resistor in kn
N = number of drivers.
C. Input Slew Rate
The slew rate of the logic input must be in excess
of 0.3V /p.s in order to assure proper operation of
the analog switch. DTL, TTL, and RTL output
rise times are far in excess of the minimum slew
rate requirements. Discrete logic designs, however,
should include consideration of input rise time.
2. ENABLE CONTROL

Connection of almA current source between V R
and V- will allow operation over a ±10V common
mode range. Differential input voltage must be less
than the 6V breakdown, and input threshold of
2.5V and 300mV differential overdrive still prevail.
»
~
4. ANALOG VOLTAGE CONSIDERATIONS
N
The rules for operating the AH0100 series at
supply voltages other than those specified essen·
tially breakdown into OFF and ON considerations.
The OFF considerations are dictated by the maxi·
mum negative swing of the analog signal and the
pinch off of the JFET switch. In the OFF state,
the gate of the FET is at V- + VBe + VSAT or
about 1.0V above the V- potential. The maximum
Vp of the FET switches is 7V. The most negative
analog voltage, V A, swing which can be accomo·
dated for any given supply voltage is:
IVAI':::; IV-I- Vp
-
...o
VA':::; V+ - VSAT - VBe -1.0V or
VA':::; v+ - 2.0V or V+
o
.....
»~
?:. VA + 2.0V
For the standard high level switches, VA = 12 2.0V = +10V.
...w
o
o
.....
5. SWITCHING TRANSIENTS
»
~
Due to charge stored in the gate·to·source and
gate-to-drain capacitances of the FET switch, transients may appear in the output during switching.
This is particularly true during the OFF to ON
transition. The magnitude and duration of the
transient may be minimized by making source
'and load impedance levels as small as practical.
VBe - VSAT or
Iv AI~lv-I-B.o or IV-I~IV AI+B.OV

o
~
o
......
»~
...o
~
'''"'~
For the standard high level switches, VA <1- 1B I
+B = -10V. The value for V+ is dictated-by the
maximum positive swing of the analog input voltage. Essentially the collector to base junction of
the turn-on PNP must remain reversed biased for
all positive value of analog input voltage. The base
of the PNP is at V+ - VSAT - V Be or V+ - 1.0V.
The PNP's collector base junction should have at
least 1.0V reverse bias. Hence, the most positive
analog voltage swing which may be accommodated
for a given value of V+ is:
U'I
o
.....
"""--"
=l>-J
»~
1'"
9en
Furthermore, transients may be minimized by
operating the switches in the differential mode;
i.e., the charge delivered to the load during the
ON to OFF transition is, to a large extent, cancelled by the OF F to ON transition.

(2b) predicts: 10V
R1(MIN) >---= 5kn

For R, = R2 , gain accuracy is determined by the
rOS(ON) match between a, and O 2 , Standard
match between a, and O2 is 50n resulting in a
gain accuracy of 0.5% (for R, = R2 = 10k).
Tighter rOSION) match versions are available.
Noise Immunity
The switches with the source diodes grounded
exhibit improved noise immunity for positive
analog signals in the "OFF" state. With VIN = 15V
and the VA = +10V, the source of a, is clamped
to about 0.6V by the diode (V GS = 14.4V). The
"ON" impedance of the diode is about 26n
ensuring that AC signals imposed on the +10V
will not gate the FET "ON."
For R, = 5k, Is ~ 10V/5k or 2 mAo The electrical
characteristics guarantee an 10(ON) :::; l/LA at 85°C
for the AH5010C. Per the criterion of equation
(2a):
(1 OV)( 10- 3 )
R1(MIN) >
> 10kn
1 x 10-6
Since equation (2a) predicts a higher value, the
10k resistor should be used.
y.,o-Wo.-(].....- ,
Selection of Gain Setting Resistors
Since the AH5009 series of analog switches are
operated current mode, it is generally advisable to
make the signal current as large as possible. tiow·
ever, current through the FET switch tends to for·
ward bias the gate to channel (source) diode
resulting in leakage across the diode. This leakage,
10ION), increases exponentially with increasing Is.
As shown in Figure 2, 10(ON) represents a finite
error in the current reaching the summing junction
of the op amp.
7·16
FIGURE 3.
The "OFF" condition of the FET also effects gain
accuracy. As shown in Figure 3, the leakage across
O2 , 10IOFF) represents a finite error in the current
arriving at the summing junction of the op amp.

Standard TTL gates pull·up to about 3.5V (no
load). In order to ensure turn·off of the even
numbered switches such as AHS010, a pull-up
resistor, R EXT , of at least 10 kn should be placed
between the SV Vee and the gate output as shown
in Figure 4.
Likewise, the open-collector, high voltage TTL
outputs should use a pull-up resistor as shown in
Figure S. In both cases, t(OFF) is improved for
lower values of R EXT and the expense of power
dissipation in the low state.

general description
The AMl 000 series are junction FET integrated cir·
cuit analog switches. These devices commutate
faster and with less voltage spiking than any other
analog switch presently available. By comparison,
discrete JFET switches require elaborate drive cir·
cuits to obtain reasonable performance for high
toggle rates. Encapsulated in a four pin TO·72
package, these units require a minimum of circuit
board area. Switching transients are greatly reduced
by a monolithic integrated circuit process. The
resulting analog switch device provides the follow·
ing features:
• Low ON Resistance
• High Analog Signal Frequency

MOS technology. To simplify external logic requirements, a one-of· eight decoder and an output
enable are included in the device.
Important design features include:
•
•
•
•
•
TTLlDTL compatible input logic levels
Operation from standard +SV and -lSV supplies
Wide analog voltage range - ±SV
One-of-eight decoder on chip
Output enable control
•
•
•
Low ON resistance - lS0n
Input gate protection
Low leakage currents - O.S nA
The AM370S/AM370SC is designed as a low cost
analog multiplex switch to fulfill a wide variety of
data acquisition and data distribution applications
including cross-point switching, MUX front ends
for A/D converters, process controllers, automatic
test gear, programmable power supplies and other
military or industrial instrumentation applications.
The AM370S is specified for operation over the
-SSoC to +12SoC military temperature range. The
AM370SC is specified for operation over the - 2SoC
to +8SoC temperature range.

MI L-STD-883
Mil-Standard-883 is a Test Methods and Procedures
Document for Microelectronic Circuits. It was
derived from MIL.S-19500, MIL·STD-750, and
MI L·STD-202C for transistors and diodes at about
the time that National Semiconductor Corporation
was entering the military microelectronics market.
As a result, our standard quality control operations
are written around MI L-STD-883. The bonding
control, visual inspections, and post seal screening
requirements set forth by 883 (as well as added
control procedures beyond the requirements of
883) have been part of National's quality control
procedures almost from the start. Our Quality
Assurance Procedures Manual is available upon
request.

We offer a complete line of linear/883 (Class B)
products as standard, off-the·shelf items. Special
Linear /883 data sheets have been prepared to
reflect this capability. They show process flow,
electrical parameters, end of test criteria, and test
circuits. We save you the problem of specifying test
and inspection procedures, and offer significant
cost savings by having an off-the·shelf, "to the
letter" 883 program. In addition, we will test any
of our integrated circuits to any class of MILSTD-883.
The detailed information concerning MI L·STD·883
screening is contained in National's specification
NSC 10002.
MIL-M-38510
MIi..·M-38510 specifies the general requirements
for supplying microcircuits. These are; product
assurance, which includes screening and quality
conformance inspection; design and construction;
marking; and workmanship. The screening and
quality conformance inspection are conducted in
accordance with MI L-STD·883.
Screening
All microcircuits delivered in accordance with Mi LM-38510 must have been subjecte'd to, and passed
all the screening tests detailed in Method 5004 of
MIL·STD·883 for the type of microcircuit and
product assurance level.
The device electrical and package requirements of
MIL·M·38510are detailed by a device specification
referred to as a slash sheet. Each slash sheet defines
the microcircuit electrical performance and mech·
anical requirements. Each device listed on a slash
sheet is referred to as a slash number and the group
of the microcircuits contained on a slash sheet is
defined as a family of devices. The device may be
Class B o~ C as defined by MI L·STD·883, Method
5004 and 5005. Three lead finishes are allowed
by the slash sheet, pot solder dip, bright tin plate,
and gold plate.
The MIL·M·38510 specs for standard linear devices
require 100% DC testing at 25°C, -55°C and
+125°C. AC testing is performed at +25°C. The
electrical parameters specified are tighter than the
normal data sheet guaranteed limits. Additionally,
9-10
MIL·M·38510 requires device traceability, exten·
sive documentation and closely matched mainten·
ance.
Quality Conformance
Quality conformance inspection is conducted in
accordance with the applicable requirements of
Group A, (electrical test), Group Band C, (environ·
mental test) of Method 5005, MIL·STD·883. These
tests are conducted on a sample basis with GroupA
performed on each sublot, Group B on each lot,
and Group C as specified (usually every three
months).
To supply devices to MIL·M-38510, the IC manu·
facturer must quality the devices he plans to supply
to the detail specifications. Qualification consists
of notifying the qualifying activity of one's intent
to qual ify to MIL -M-3S51 O. After passi ng comprehensive audits of facilities and documentation
systems, the IC manufacturer will subject tl)e
device to and demonstrate that they satisfy all of
. the Group A, B, and C requirements of Method
5005 of MI L·STD-883 for the specified classes and
types of IC. The qualification tests shall be monitored by the qualifying agency. Finally the IC
manufacturer shall prepare and submit qualifica·
tion test data to the qualifying agency. Groups A,
B, and C inspections then shall be performed at
intervals no greater than three months.
The purpose of qualification testing is to assure
that the device and lot quality conform to certain
standard limits. In effect, lot qualification tests
tend to ensure that once a particular device type
is demonstrated to be acceptable,. it's production,
including materials, processing, and testing will
continue to be acceptable. These limits are specified in MIL·STD·883 in terms of LTPD's (Lot
Tolerance Percent Defective) for the various quali·
fication test sub-groups. Qualification testing is
performed-on a sample of devices which are chosen
at random from a lot of devices that has satisfactorily completed the screening of Method 5004
must be performed on each device, i.e. on a 100%
basis as opposed to qualification testing (Method
5005) which occurs on a random sample basis.
In summary, the entire purpose of MIL-M-38510
and MIL-STD-883 is to provide the military,
through its contractors with standard devices.
We at National Semiconductor have supplied and
are supplying devices to the MIL-M-38510 specifications. To order a MIL-M-38510 microcircuit,
specify the following:
For example; to specify an LM741 in a DIP
processed to the requirements of MI L-M-38510,
Class B, with gold plated leads, specify M-38510/
10101BCC.
