TECHNICAL NOTES
1. Applications which are unaffected by endpoint errors or remove them through software will use the typical connections
shown in Figure 3. Remove system errors or adjust the
small initial errors of the ADS-III to zero using the optional
external circuitry shown in Figure 4. The external adjustment circuit has no affect on the throughput rate.
2. Rated performance requires using good high-frequency circuit board layout techniques. The analog and digital

grounds are not connected internally. Avoid ground-related
problems by connecting the digital and analog grounds to
one point, the ground plane beneath the converter. Due to
the inductance and resistance of the power supply return
paths, return the analog and digital ground separately to the
power supplies.
3. Bypass the analog and digital supplies ~nd the +10V reference (pin 21) to ground with a 4.7 IlF, 25V tantalum electrolytic capaCitor in parallel with a 0.1 IlF ceramic capacitor.
Bypass the +1 OV reference (pin 21) to analog ground (pin
23).
4. Obtain straight binary/offset binary output coding by tying
COMI'Q31N (pin 18) to +5V dc or leaving it open. The device has an internal pull-up resistor on this pin. To obtain
complementary bin1!'Y.P! cQ.rnplementary offset binary ou!::
~ coding, tie the COMP BIN pin to ground. The COMP
BIN signal is compatible to CMOSITTL logic levels for those
users desiring logic control of this function.
5. To obtain three-state outputs, connect ENABLE (pin 17) to a
logic "0" (low). Otherwise, connect ENABLE (pin 17) to a
logic "I" (high).

TIMING
Figure 2 shows the relationship between the various input signals. The timing shown applies over the 0Pfilrating temperature
range and over the operating power supply range. These times
are guaranteed by design

CALIBRATION PROCEDURE
1. Connect the converter per Figure 3, Figure 4, and Table 1 for
the appropriate full-scale range (FSR). Apply a pulse of 200
nanoseconds minimum to the START CONVERT input (pin
16) at a rate of 250 KHz. This rate is chosen to reduce flicker
if LED's are used on the outputs for calibration purposes.
2. Zero Adjustments
Apply a preciSion voltage reference source between the amplifier's analog input and ground. Adjust the output of the
reference source per Table 2. For unipolar, adjust the zero
trimming potentiometer so that the output code flickers
equally between 0000 0000 0000 and 0000 0000 0001 with
the COMP BIN (pin 18) tied high (straight binary) or between 1111 1111 1111 and 1111 1111 1110 with pin 18 tied
low (complementary binary).
For bipolar operation, adjust the potentiometer such that the
code flickers equally between 1000 0000 0000 and 1000
00000001 with (pin 18) tied high (offset binary) or between
011111111111 andOllllllllll0with(pin18)tiedlow
(complementary offset binary).
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2. Adjust the gain trimming potentiometer so that the output code flickers equally between 1111
1111 1110 and 1111 1111 1111 for (pin 18) tied high or between 0000 0000 0001 and 0000 0000 0000 for (pin 18) tied
low.
4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 4.

TECHNICAL NOTES

CALIBRATION PROCEDURE

1. Use external potentiometers to remove system errors or to
reduce the small initial errors to zero. Use a 20K trimming
potentiometer for gain adjustment with the wiper tied to pin
15 (tie pin 15 to ANALOG GROUND for operation without
adjustments). Use a 20K trimming potentiometer with the
wiper tied to pin 11 for zer%ffset adjustment (tie pin 11 to
ANALOG GROUND for operation without adjustment).

1. Connect the converter per Figure 2.
Apply a pulse of 10 nS typical to the START CONVERT input (pin 35) at a rate of 500 KHz. This rate is chosen to reduce flicker if LED's are used on the outputs for calibration
purposes.

2. Rated performance requires using good high-frequency circuit board layout techniques. Avoid ground-related problems by connecting the digital and analog grounds to one
point, the ground plane beneath the converter.
In most cases, users will use a single +5V supply for both
analog +5V and digital +5V (applicable for the -5V supply
also). Should users have separate supplies the difference
between the analog and digital supply should be within
±100 mV to avoid performance degradation.
Due to the inductance and resistance of the power supply
return paths, return the analog and digital ground separately
to the power supplies. This prevents contamination of the
analog ground by noisy digital ground currents.
3. Bypass all the analog and digital power supply pins with a
2.2 !LF, 25V tantalum electrolytic capacitor in parallel with a
0.1 !LF ceramic capacitor to their respective analog and digital grounds. Use of chip capacitors is recommended.
4. Obtain offset binary output coding by tying COMP BIN (pin
39) to +5V dc. To obtain complementary offset binary output coding, tie pin 39 to ground. The pin 39 signal is compatible to CMOSITTL logic levels for those users desiring
logic control of this function.
5. To obtain three-state outputs, connect the ENABLE pin (pin
38) to a logic "1" (high). Otherwise, connect pin 38 to a logic
"0" (low).
6. The ADS-130 guarantees it's specified throughput rate over
the temperature range when the START CONVERT pulse
of 10 nS minimum, 90 nS maximum is provided at the specified rate. Start convert pulses greater than 90 nanoseconds
will result in slower throughput rates.
7. The ADS-130 is capable of digitizing sinusoidal input frequencies up to the Nyquist frequency. The acquisition time
for pulse or dc level signals is 50 nS maximum over the 0
to +70 °C temperature range. Acquisition time is 70 nSec.
maximum from -55°C to + 125 °C.
8. The speCifications listed in Figure 2 (timing diagram) apply
over the full operating temperature range unless otherwise
specified.

2. Zero Adjustments
Apply a precision voltage reference source between the analog input (pin 6) and analog ground. Adjust the output of
the reference source per Table 2 for the bipolar zero adjustment (zero +1/2 LSB). Adjust the potentiometer such that
the code flickers equally between 1000 0000 0000 and
1000 0000 0001 with COMP BIN (pin 39) tied high (offset binary) or between 0111 1111 1111 and 0111 1111 1110 with
pin 39 tied low (complementary offset binary).
3. Full·Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2 for the bipolar gain adjustment
(+FS -1 1/2 LSB). Adjust the gain trimming potentiometer so
that the output code flickers equally between 1111 1111
1110 and 1111 1111 1111 with pin 39 tied high or between
000000000000 and 000000000001 with pin 39 tied low.
To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 3.

TECHNICAL NOTES

CALIBRATION PROCEDURE

1. Use external potentiometers to remove system errors or to
reduce the small initial errors to zero. Use a 20K trimming
potentiometer for gain adjustment with the wiper tied to pin
15 (tie pin 15 to ANALOG GROUND for operation without
adjustments). Use a 20K trimming potentiometer with the
wiper tied to pin 11 for zer%ffset adjustment (tie pin 11 to
ANALOG GROUND for operation without adjustment).

1. Connect the converter per Figure 2.
Apply a pulse of 10 nS typical to the START CONVERT input (pin 35) at a rate of 500 KHz. This rate is chosen to reduce flicker if LED's are used on the outputs for calibration
purposes.

2. Rated performance requires using good high-frequency circuit board layout techniques. Avoid ground-related problems by connecting the digital and analog grounds to one
pOint, the ground plane beneath the converter.
In most cases, users will use a single +5V supply for both
analog +5V and digital +5V (applicable for the -5V supply
also). Should users have separate supplies the difference
between the analog and digital supply should be within
±100 mV to avoid performance degradation.
Due to the inductance and resistance of the power supply
return paths, return the analog and digital ground separately
to the power supplies. This prevents contamination of the
analog ground by noisy digital ground currents.
3. Bypass all the analog and digital power supply pins with a
2.2 ~F, 25V tantalum electrolytic capacitor in parallel with a
0.1 ~F ceramic capacitor to their respective analog and digital grounds. Use of chip capacitors is recommended.
4. Obtain offset binary output coding by tying COMP BIN (pin
39) to +5V dc. To obtain complementary offset binary output coding, tie pin 39 to ground. The pin 39 signal is compatible to CMOSmL logic levels for those users desiring
logic control of this function.

2. Zero Adjustments
Apply a precision voltage reference source between the analog input (pin 6) and analog ground. Adjust the output of
the reference source per Table 2 for the bipolar zero adjustment (zero +1/2 LSB). Adjust the potentiometer such that
the code flickers equally between 1000 0000 0000 and
100000000001 with COMP BIN (pin 39 tied high (offset binary) or between 011111111111 and 011111111110with
pin 39 tied low (complementary offset binary).
3. Full·Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2 for the bipolar gain adjustment
(+FS -1 1/2 LSB). Adjust the gain trimming potentiometer so
that the output code flickers equally between 1111 1111
1110 and 1111 1111 1111 with COMP BIN (pin 39) tied
high or between 0000 0000 0000 and 0000 0000 0001 with
pin 39 tied low.
To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 3.

7. The ADS-131 is capable of digitizing sinusoidal input frequencies up to the Nyquist frequency. The acquisition time
for pulse or dc level signals is 70 nS maximum over the 0
to +70 °C temperature range. Acquisition time is 100 nSec.
maximum from -55°C to +125 DC.
8. The specifications listed in Figure 3 (timing diagram) apply
over the full operating temperature range unless otherwise
specified.

5. To obtain three-state outputs, connect ENABLE (pin 38) to a
logic "1" (high). Otherwise, connect pin 38 to a logic "0"
(low).
6. The ADS-131 guarantees it's specified throughput rate over
the temperature range when the START CONVERT pulse
of 10 nS minimum, 190 nS maximum is provided at the
specified rate. Start convert pulses greater than 190 nanoseconds will result in slower throughput rates.

TECHNICAL NOTES
1. Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 20K trimming potentiometer for gain adjustment with the wiper tied to pin 32 (ground
pin 32 for operation without adjustments). Use a 20K trimming potentiometer with the wiper tied to pin 5 for zerol
offset adjustment (leave pin 5 open for operation without adjustment). See Figure 3.
2. Rated performance requires using good high-frequency circuit board layout techniques.
The analog and digital
grounds are not connected internally. Avoid ground-related
problems by connecting the digital and analog grounds to
one pOint, the ground plane beneath the converter. Due to
the inductance and resistance of the power supply return
paths, return the analog and digital ground separately to the
power supplies.
3. Bypass the analog and digital supplies and the +10V reference (pin 1) to ground with a 4.7 ~F, 25V tantalum electrolytic capacitor in parallel with a 0.1 ~F ceramic capacitor.
Bypass the +1 OV reference (pin 1) to analog ground (pin
16).
4. To enable the three-state outputs, connect ENABLE (pin 10)
to a logic "0" (low). To disable, connect ENABLE (pin 10) to
a logic "1" (high).
5. The ADS-132 is in the sample mode when the internal S/H
CONTROL pin is high (S/H is in the high-state on powerup). The START CONVERT pulse should be given at a
time delay equal to the desired acquisition time minus the
10 nanosecond delay from START CONVERT high to S/H
CONTROL low. This assures the sample-hold has the minimum required acquisition time for the particular application
mode.
6. Upon going into the hold mode there will be a 85 nanosecond maximum delay before EOC goes high and the AID
conversion begins. This consists for the remaining 50 nanoseconds of the START CONVERT (10 nanoseconds is part
of the acquisition time) and a 20 nanosecond maximum delay from START CONVERT low to EOC high. The hold
mode settling time requirement is met during this time.
7. Figure 2 shows the relationship between the various input
signals. The timing shown applies over the operating temperature range and over the operating power supply range.
These times are guaranteed by design.

CALIBRATION PROCEDURE
1. Connect the converter per Figure 3, and Tables 1 and 4 for
the appropriate full-scale range (FSR). Apply a pulse of 60
nanoseconds minimum to the START CONVERT input (pin
31) at a rate of 500 KHz. This rate is chosen to reduce flicker if LED's are used on the outputs for calibration purposes.
2. Zero Adjustments
Apply a preciSion voltage reference source between the amplifier's analog input and ground. Adjust the output of the
reference source per Table 2. For unipolar, adjust the zero
trimming potentiometer so that the output code flickers
equally between 0000 0000 0000 and 0000 0000 0001
(straight binary) or between 1111 1111 1111 and 1111 1111
1110 (complementary binary).
For Immediate Assistance, Dial 1-800-233-2765

For bipolar operation, adjust the potentiometer such that the
code flickers equally between 1000 0000 0000 and 1000
0000 0001 (offset binary) or between 0111 1111 1111 and
0111 1111 1110 (complementary offset binary).
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2. Adjust the gain trimming potentiometer so that the output code flickers equally between 1111
1111 1110 and 1111 1111 1111 (offset binary) or between
000000000001 and 0000 0000 0000 (complementary offset binary).
4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 3.

TECHNICAL NOTES
1. Use external potentiometers as shown in Figure 3 to adjust
the offset and gain errors to zero. For operation without adjustment, leave pin 8 open.

For bipolar operation, adjust the potentiometer such that the
code flickers equally between 1000 0000 0000 and 1000
00000001.

2. Rated performance requires using good high-frequency circuit board layout techniques. The analog and digital
grounds are connected internally. Avoid ground-related
problems by connecting the digital analog grounds to one
point, the ground plane beneath the converter.

3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2. Adjust the gain trimming potentiometer so that the output code flickers equally between 1111
11111110and 111111111111.

Due to the inductance and resistance of the power supply
return paths, return the analog and digital ground separately
to the power supplies.

4. To confirm proper operation of the device, vary the preCision
reference voltage source to obtain the output coding listed
in Table 3.

3. Bypass the analog and digital supplies to ground with a 10
j.1F, 2SV tantalum electrolytic capacitor. Bypass the +10V
reference (pin 2 and 31) to analog ground (pin 16) with a
0.1 j.1F ceramic capacitor.

4. For unipolar, 0 to -SV FSR, connect pins 31 and 32. For bipolar, ±2.SV FSR, connect pin 32 to analog ground and connect pin 31 to a 0.1 j.1F ceramic capacitor only.

binary. Refer to Table 3 for the desired coding selection. Pin
34 has an internal pull-up resistor and is TTL-compatible for
those users desiring logic control of this function.
5, The internal Sample/Hold control signal goes low following
the rising edge of a start convert pulse and hiQ.,h 65 nanoseconds minimum before EOC goes low. This S/H low signal indicates that the converter can accept a new analog input.

CALIBRATION PROCEDURE
1. Connect the converter per Figure 3 and Tables 1 and 3 for
the appropriate full-scale range (FSR) and coding options.
Apply a pulse of 100 nanoseconds minimum to the START
CONVERT input (pin 3) at a rate of 500 KHz. This rate chosen to reduce flicker if LED's are used on the outputs for calibration purposes.

For bipolar operation, adjust the potentiometer until the displayed code flickers equally between 1000 0000 0000 and
100000000001 orbetween011111111111 and01111111
1110. Refer to Table 5.
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2. Adjust the gain trimming potentiometer so that the output code flickers equally between 1111 1111
1110 and 1111 1111 1111 or between 0000 0000 0001 and
0000 0000 0000 depending on the output coding selected.

2. Zero Adjustment
Apply a preCision voltage reference source between the analog input (pin 39) and ground (pin 24). Adjust the output of the
reference source per Table 2. For Unipolar operation adjust
the zero trimming potentiometer so that the output code flickers equally between 0000 0000 0000 and 0000 0000 0001 or
between 1111 1111 111t and 1111 1111 1110. Refer to
Table 4.

TECHNICAL NOTES
1. Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 20K trimming potentiometer for gain adjustment with the wiper tied to pin 6 (ground
pin 6 for operation without adjustments). Use a 20K trimming potentiometer with the wiper tied to pin 5 for zero/
offset adjustment (connect pin 5 to pin 15, analog ground
for operation without adjustment).

2. Zero Adjustments
Apply a precision voltage reference source between the analog input (pin 3) and signal ground (pin 4). Adjust the output of the reference source per Table 2.
For unipolar, adjust the zero trimming potentiometer so that
the output code flickers equally between 00 0000 0000
0000 and 00 0000 0000 0001 with the COMP BIN (pin 8)
tied high (straight binary) or between 11 1111 1111 1111
and 11 1111 1111 1110 with the COMP BIN (pin 8) tied low
(complementary binary).

2. Rated performance requires using good high-frequency circuit board layout techniques. The analog and digital
grounds are not connected internally. Avoid ground-related
problems by connecting the digital and analog grounds to
one pOint, the ground plane beneath the converter. Due to
the inductance and resistance of the power supply return
paths, return the analog and digital ground separately to the
power supplies.

For bipolar operation, adjust the potentiometer such that the
code flickers equally be1W.e.erL1.O 0000 0000 0000 and 10
0000 0000 0001 with COMP BIN (pin 8) tied high (offset binary) or between 01 1111 1111 1111 and 01 1111 1111
1110 with COMP BIN (pin 8) tied low (complementary offset
binary).

3. Bypass the analog and digital supplies and the +10V reference (pin 1) to ground with a 4.7 ~F, 25V tantalum electrolytic capacitor in parallel with a 0.1 ~F ceramic capacitor.
Bypass the +1 OV reference (pin 1) to analog ground (pin
15).
4. Obtain straight binary/offset binary output coding by tying
COMP BIN (pin 8) to +5V dc or leaving it open. The device
has an internal pull-up resistor on this pin. To obtain complementary bin~complementary offset binary output
coding, tie the COMP BIN pin to ground. The COMP BIN
Signal is compatible to CMOSITTL logic levels for those users desiring logic control of this function.

Two's complement coding requires use of the MSB (pin 31)
with COMP BIN (pin 8) tied high, adjusting the potentiometer such that the code flickers between 00 0000 0000 0000
and 00 0000 0000 0001.
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2.
Adjust the gain trimming potentiometer so that the output
code flickers equally between 11 1111 1111 1110 and 11
1111 1111 1111 for COMP BIN (pin 8) tied high (straight binary) or between 00 0000 0000 0000 and 00 0000 0000
0001 for COMP BIN tied low (complementary binary).

5. To enable the three-state outputs, connect ENABLE (pin 9)
to a logic "0" (low). To disable, connect ENABLE (pin 9) to
a logic "1" (high).

Two's co!!!plement coding requires use of the MSB (pin 31)
with the COMP BIN (pin 8) tied high, adjusting the gain trimming potentiometer so that the output code flickers equally
between 01 1111 1111 1110 and 01 1111 1111 1111.

6. The 200 nSec. minimum START CONVERT pulse width assures the hold mode settling time requirements are met.
7. The specifications listed in Figure 2 (timing diagram) apply
over the full operating temperature range unless otherwise
specified.

4. To confirm proper operation of the device, vary the preCision
reference voltage source to obtain the output coding listed
in Table 3.

CALIBRATION PROCEDURE
1. Connect the converter per Figure 3, and Table 1 for the appropriate full-scale range (FSR). Apply a pulse of 200 nanoseconds minimum to the START CONVERT input (pin 32)
at a rate of 200 KHz. This rate is chosen to reduce flicker if
LED's are used on the outputs for calibration purposes.

ADS·941
TECHNICAL NOTES
1. Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 200 n trimming potentiometer in series with the analog input for gain adjustment.
Use a short in place of the gain adjustment trim pot for operation without adjustments. Use a 20K trimming potentiometer with the wiper tied to pin 5 for zer%ffset adjustment
(connect pin 5 to pin 15, analog ground for operation without adjustment).

2. Zero Adjustments
Apply a precision voltage reference source between the analog input (pin 3) and signal ground (pin 4). Adjust the output
of the reference source per Table 2.
For unipolar, adjust the zero trimming potentiometer so that
the output code flickers equally between 00 0000 0000
0000 and 00 0000 0000 0001 with the COMP BIN (pin 8)
tied low (straight binary) or between 11 1111 1111 1111
and 11 1111 1111 1110 with the pin 8 tied high (complementary binary).

2. Rated performance requires using good high-frequency circuit board layout techniques. The analog and digital
grounds are not connected internally. Avoid ground-related
problems by connecting the digital and analog grounds to
one point, the ground plane beneath the converter. Due to
the inductance and resistance of the power supply return
. paths, return the analog and digital ground separately to the
power supplies.

For bipolar operation, adjust the potentiometer such that the
code flickers equally between 10 0000 0000 0000 and 10
0000 0000 0001 with pin 8 tied high (offset binary) or between 01 1111 1111 1111 and 01 1111 1111 1110 with pin
8 tied low (complementary offset binary).

3. Bypass the analog and digital supplies and the +1 OV reference (pin 1) to ground with a 4.7 ~F, 25V tantalum electrolytic capacitor in parallel with a 0.1 ~F ceramic capaCitor.
Bypass the + 1OV reference (pin 1) to analog ground (pin
15).
4. Obtain straight binary/offset binary output coding by tying
COMP BIN (pin 8) to +5V dc or leaving it open. The device
has an internal pull-up resistor on this pin. To obtain com.plementary binary or complementary offset binary output
coding, tie the COMP BIN pin to ground. The COMP BIN
signal is compatible to CMOSmL logic levels for those users desiring logic control of this function.

Two's complement coding requires use of the MSB (pin 31)
with COMP BIN (pin 8) tied high, adjusting the potentiometer such that the code flickers between 00 0000 0000 0000
and 00 0000 0000 0001.
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2.
Adjust the gain trimming potentiometer so that the output
code flickers equally between 11 1111 1111 1110 and 11
1111 1111 1111 for COMP BIN (pin 8) tied low for unipolar
operation or tied high for bipolar operation (straight binary/
offset binary) or between 00 0000 0000 0000 and 00 0000
0000 0001 for COMP BIN tied high for unipolar operastionor tied low for bipolar operation (complementary binary!
complementary offset binary).

5. To enable the three-state outputs, connect ENABLE (pin 9)
to a logic "a" (low). To disable, connect ENABLE (pin 9) to
a logic "1" (high).

Two's complement coding requires use of the MSB (pin 31)
with the COMP BIN (pin 8) tied high, adjusting the gain trimming potentiometer so that the output code flickers equally
between 01111111111110 and 01111111111111.

CALIBBATION"PROCEDURE
1. Connect the converter per Figure 3, and Table 1 for the appropriate full-scale range (FSR). Apply a pulse of 50 nanoseconds minimum to the START CONVERT input (pin 32)
at a rate of 200 KHz. This rate is chosen to reduce flicker if
LED's are used on the outputs for calibration purposes.

4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 3.

ADS-942
TECHNICAL NOTES
1. Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 200 Q trimming potentiometer in series with the analog input for gain adjustment.
Use a short in place of the gain adjustment trim pot for operation without adjustments. Use a 20K trimming potentiometer with the wiper tied to pin 5 for zer%liset adjustment
(connect pin 5 to pin 15, analog ground for operation without adjustment).

2. Zero Adjustments
Apply a precision voltage reference source between the analog input (pin 3) and signal ground (pin 4). Adjust the output of the reference source per Table 2.
For unipolar, adjust the zero trimming potentiometer so that
the output code flickers equally between 00 0000 0000
0000 and 00 0000 0000 0001 with the COMP BIN (pin 8)
tied low (straight binary) or between 11 1111 1111 1111
and 11 1111 1111 1110 with the pin 8 tied high (complementary binary).

2. Rated performance requires using good high-frequency circuit board layout techniques. The analog and digital
grounds are not connected internally. Avoid ground-related
problems by connecting the digital and analog grounds to
one point, the ground plane beneath the converter. Due to
the inductance and resistance of the power supply return
paths, return the analog and digital ground separately to the
power supplies.
3. Bypass the analog and digital supplies and the +10V reference (pin 1) to ground with a 4.7I1F, 25V tantalum electrolytic capacitor in parallel with a 0.1 I1F ceramic capacitor.
Bypass the +1 OV reference (pin 1) to analog ground (pin
15).
4. Obtain straight binary/oliset binary output coding by tying
COMP BIN (pin 8) to +5V dc or leaving it open. The device
has an internal pull-up resistor on this pin. To obtain complementary binary or complementary oliset binary output
coding, tie pin 18 to ground. The pin 18 signal is compatible
to CMOSITTL logic levels for those users desiring logic control of this function.

For bipolar operation, adjust the potentiometer such that the
code flickers equally between 10 0000 0000 0000 and 10
0000 0000 0001 with pin 8 tied high (oliset binary) or between 011111 1111 1111 and 01111111111110 with pin
8 tied low (complementary oliset binary).
Two's complement coding requires use of the IiiffiB (pin 31)
with CQMP BIN (pin 8) tied high, adjusting the potentiometer such that the code flickers between 00 0000 0000 0000
and 00 0000 0000 0001.
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2.
Adjust the gain trimming potentiometer so that the output
code flickers equally between 11 1111 1111 1110 and 11
1111 1111 1111 for CQMP BIN (pin 8) tied low for unipolar
operation or tied high for bipolar operation (straight binary/
oliset binary) or between 00 0000 0000 0000 and 00 0000
0000 0001 forCOMP BIN tied high for unipolar operastionor tied low fdr bipolar operation (complementary binary/
complementary oliset binary).

5. To enable the three-state outputs, connect ENABCE (pin 9)
to a logic "0" (low). To disable, connect pin 9 to a logic "1"
(high).

Two's complement coding requires use of the MSB (pin 31)
with the COMP BIN (pin 8) tied high, adjusting the gain trimming potentiometer so that the output code flickers equally
between 01 1111 1111 1110 and 01 1111 1111 1111.

CALIBRATION PROCEDURE
1. Connect the converter per Figure 3, and Table 1 for the appropriate full-scale range (FSR). Apply a pulse of 35 nanoseconds minimum to the START CONVERT input (pin 32) at
a rate of 200 KHz. This rate is chosen to reduce flicker if
LED's are used on the outputs for calibration purposes.

4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 3.

GENERAL DESCRIPTION
The ADC-207 is the industry's first 7-bit flash converter
using a high-speed 1.2 micron CMOS process. This
process offers some very distinctive advantages over other
processes, making the ADC-207 a very unique device. The
smaller geometrics of the process achieves high-speed,
better linearity ·and better temperature performance. Since
the ADC-207 is a CMOS device, it also has very low power
consumption (250 mW). The device draws power from a
single +5V supply, and is conservatively rated for 20 MHz
operation. The ADC-207 allows using sampling apertures
as small as 12nS, making it more closely approach an ideal
sampler. The small sampling apertures also let the device
operate at greater than 20 MHz.

TECHNICAL NOTES
1. Input Buffer Amplifier-Since the ADC-207 has a switched
capacitor type input, the input impedance of the 207 is
dependent on the clock frequency. At relatively slow conversion rates a general purpose type input buffer can be
used; at high coversion rates DATEL recommends either
the HA-5033, the LH-0033 or Elantec 2003.See Figure 2
for typical connections.
2.· Reference Ladder-Adjusting the voltage at + Ref adjusts
the gain of the ADC-207. Adjusting the voltage at -Ref
adjusts the offset or zero of the ADC-207. The midpoint pin
is usually bypassed to ground through a .1uf capacitor,
although it can be tied to a pFecision voltage halfway
between + Ref and -Ref. This would improve integral linearity beyond 7 bits.
3. Clock Pulse Width-To improve performance at Nyguist
bandwidths, the clock duty cycle can be adjusted so that the
low portion of the clock pulse is 12 nseconds wide. The
smaller aperature allows the ADC-207 to closely resemble
an ideal sampler.
CAUTION
Since the ADC-207 is a CMOS device, normal precautions against static electricity should be taken. use
ground straps, grounded mats, etc. The Absolute Maximum Ratings of the device MUST NOT BE EXCEEDED
as irrevocable damage to the ADC-207 will occur.

for code changes at the midpoints between these center values
shown in Table 1. For example, at the half-scale major carry, set
the input to 2.54V and adjust the reference until the code flickers equally between 63 and 64. Note also that the weighting for
the comparator resistor network leaves the first and last
thresholds to within V. LSB of the end paints to adjustthe code

GENERAL DESCRIPTION
The ADC-20S utilizes an advanced VLSI 1.2 micron CMOS in
providing 20 MHz sampling rates at S-bits. The flexibility of the
design architecture and process delivers effective bit rates to
30 MHz in the burst mode, one shot mode conversion times of
35 nanoseconds, low power modes to 150 mW, latch-up free
operation without external components and operation over the
full military temperature range.
The ADC-20S has 256 auto-zeroing comparators which are
auto-balanced on every conversion to cancel out any offsets
due to temperature and/or dynamic effects. These comparators sample the difference between the analog input and the
reference voltages generated by the precision reference ladder network. Parallel output data and the overflow pin have
Three-State outputs. The overflow pin allows cascading two
devices for 9-bit operation.

1. Rated performance requires using good high frequency
techniques. The analog and digital grounds are connected
internally. Avoid ground related problems by connecting the
grounds to one point, the ground plane beneath the converter. Due to the inductance and resistance of the power supply return paths, return the analog and digital ground separately to the power supplies.

GENERAL DESCRIPTION
DATEL's ADC-304 is an 8-bit, 20 MHz analog-to-digital
flash converter. The ADC-304 offers many performance
features not obtainable from other flash AID's.
Key features include a low-power dissipation of 390 mW
and TTL compatible outputs. A wide analog input bandwidth
of 8 MHz (-3 dB) allows operation without the need of a
sample-hold. Also, single +5V sUpply operation is
obtainable with an input range of +3 to +5V, eliminating the
need for an additional power supply. A 0 to -2 V input range
is available with ±5V supply operation.

Another novel feature of the ADC-304 is its user-selectable
output coding. The MINV and LlNV pins allow selection of
binary, complementary binary, and if external offset circuitry
is used for bipolar inputs, offset binary, two's complement,
and complementary two's complement coding.

1. DIG GND pins (5 and 11) and Vce
pins (6 and 10) connect to separate
internal circuits within the ADC-304.
Connect these pins to their respective
PCB patterns.
2. Layout of the analog and digital sections should be separated to reduce
interference from noise. To further
guard against unwanted noise, it is
recommended to bypaSs, as close as
possible. the voltage supply pins
(6.10) to their respective ground pins
(5,11) with a 1 p.F and a 0.01 p.F ceramic disk capacitor in parallel.

FUNCTIONAL SPECIFICATIONS
Unless otherwise noted, the following specifications apply to
the ADC-304 when used either with a single or dual power
source. The test conditions are:

3. The input capacitance of the analog
input is much smaller than that of a
typical Flash AID Converter. It is
necessary to use an amplifier with
sufficient bandwidth and driving
power. The analog input pins (21.23)
are separated internally, so they
should be connected together externally. If the ADC-304 is driven with a
low- output impedance amplifier.
parasitic oscillations may occur.

For Single Power Supply Operation:
Vee (Pins 6 + 10) = +5V, DIG GND = OV
VEE (Pins 7. 8 + 9) = OV. VRT (Pin 18) = +5V
VR. (Pin 26) = +3V, Ta = 25°C
ANA GND (Pins 19 + 25) = + 5V
For Dual Power Supply Operation:
Vee (Pins 6 + 10) = +5V,DIGGND(Pins5 + 11) = OV
ANA GND = OV, VEE = -5V
VRT(Pin18) = OV, VR. (Pin 26) = -2V

These parasitic oscillations can be
prevented by introducing a small
resistance of 2 to 10Q between the
amplifier output and the ADC-304's
AID input. This resistance must be of
very low value of inductance at high
frequencies.
Note that each of the analog input
pins are divided in this manner with
these resistances. Connect the driving amplifier as close as possible to
the AID input of the ADC-304.
4. The voltage between VAT (pin 18)
and VAB (pin 26) is equivalent to the
dynamic range of the analog input.
Bypass VAB to ANA GND (pins 19
and 25) by means of a lp.F and 0.01
p. F capacitor in parallel. To balance
the characteristics of the ADC-304 at
high frequencies. bypass VAM (pin
27) with a 0.01p. F capacitor to ANA
GND (pins 19 and 25).
Also. VAM (pin 27) can be used as a
trimming pin for more precise linearity compensation. A stable voltage
source with a potential equal to -FSA
and a 1 KQ potentiometer can be connected to VAM (pin 27) as shown in
Figure 3 for this purpose.
5. Separate the clock input. CLK (pin 17).

observing proper EMI and AFI wiring
techniques. This will reduce the
inductive pick-up of this lead from
interfering with the "clean'" operation
of the ADC-304.

6. The analog input signal is sampled on
the positive-going edge of ClK. Corresponding digital data appears at the
output on the negative-going edge of
the ClK pulse after a small delay of 35
nSec. maximum (TDlH, TDHl).
Refer to the Timing diagram, Figure 4,
for more information.
7. Connect all free pins to ANA GND
(pins 19 and 25) to reduce unwanted
noise.
The analog input range is equal to a
2V spread. The voltage on VRT-VRB
will equal 2V. The connection of VRT
and ANA GND is 2V higher than VRB.
Whether using a single or dual power
supply, the analog input will range
from the value of VRT to VRB. If VRT
equals +5V, then VRB will equal +:N
and the analog input range will be
from +5 to +:N.

TECHNICAL NOTES
1 . Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 20K trimming potentiometer for
gain adjustment with the wiper tied to pin 32 (ground pin 32 for
operation without adjustments). Use a 20K trimming potentiometer with the wiper tied to pin 5 for zer%ffset adjustment (leave
pin 5 open for operation without adjustment).
2. Rated performance requires using good high frequency circuit
board layout techniques. The analog and digital grounds are not
connected internally. Avoid ground-related problems by connecting the digital and analog grounds to one pOint, the ground plane
beneath the converter. Due to the inductance and resistance of
the power supply return paths, return the analog and digital
ground separately to the power supplies.

DATEL, Inc. 11 Cabot Boulevard, Mansfield, MA 02048-1194ITEL (508) 339-3000ITLX 174388/FAX (508) 339-6356

ADC·SOO, ADC·505
3. Bypass all the analog and digital supplies and the + 1OV reference (pin 1) to ground with a 4.7 IlF, 25V tantalum electrolytic capacitor in parallel with a 0.1 IlF ceramic capacitor. Bypass the
+ 1OV reference (pin 1) to analog ground (pin 16). The -5V dc
supply is treated as an analog supply and analog ground (pin 16)
should be treated as its return path for decoupling purposes.
4. Obtain straight binary/offset binary output coding by tying COMP
BIN (pin 7) to +5V dc or leaving it open. The device has an internal pull-up resistor on this pin. To obtain complementary binary
or complementary offset binary output coding, tie the COMP BIN
pin to ground. The COMP BIN signal is compatible-to CMOS/
TTL logic levels for those users desiring logic control of this function.

8. Over temperature, input capacitance is 50 pF maximum and input impedance is 1.75K minimum (2.5K typical) for unipolar and
3.75K minimum (5K typical) for bipolar. These values are guaranteed by design.
9. Requirements for ±2.5V inputs can be satisfied using DATEL's
AM-1435 amplifier in front of the SHM-45/ADC-500 configuration,
shown in Figure 3, at the appropriate gain. The SHM-45's gain of
2 mode allows 0 to +5V or ±5V input ranges.

TIMING
Figure 2 shows the relationship between the various input signals.
The timing cited applies over the operating temperature range and
over the operating power supply range. These times are guaranteed by design.

5. An overflOW signal, pin 8, indicates when analog input signals are
below or above the desired full-scale range. To overflow pin also
has a three-state output and is enabled by pin 10 (Enable bits 1-5
&O.F.).

TABLE 2. INPUT CONNECTIONS

6. The Sample/Hold control signal, pin 17, goes low following the
rising edge of START QQt::IVERT pulse and high 30 nanoseconds minimum before EOC goes low. This indicates that the
converter can accept a new analog input.

flickers equally between 0000 0000 0000 and 0000 0000 0001
with the COMP BIN (pin 7) tied high or between 1111 1111
1111 and111111111110withtheCOMPBINtiedlow.

Removal of system errors or the small initial errors is accomplished
as follows:
1. Connect the converter per Figure 3 and Table 2 for the appropriate full-scale range (FSR). Apply a pulse of 50 nanoseconds
minimum to the START CONVERT input (pin 31) at a rate of
500 KHz. This rate chosen to reduce flicker if LED's are used
on the outputs for calibration purposes.

3. Full-Scale Adjustment - Set the output of the voltage reference
used in step 2 to the value shown in Table 3. Adjust the gain
trimming potentiometer so that the output code flickers equally
between 1111 1111 1110 and 1111 1111 1111 for COMP BIN
(pin 7) tied high or between 0000 0000 0001 and 0000 0000
0000 for COMP BIN tied low.

2. Zero Adjustments - Apply a precision voltage reference source
between the analog input (pin 3) and ground (pin 16). Adjust
the output of the reference source per Table 3. For unipolar,
adjust the zero trimming potentiometer so that the output code

conjunction with the ADC-508. This feature allows the sample-andhold device to go back into the sample mode a minimum of 30
nanoseconds before the conversion is complete, improving the
overall conversion rate of the system.
Power required is ± 15V de and ± 5V dc. Models are available in the.
commerc;ial O·C to + 70°C, and military - 55°C to + 125°C operating temperature range. Typical applications include spectrum, transient, vibration, and waveform analysis. These devices are also
ideally suited for radar, sonar and video digitization, medical instrumentation, and high-speed data acquisition systems. For information

TECHNICAL NOTES
1 . Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 20K trimming potentiometer for
gain adjuslment with the wiper tied to pin 32 (ground pin 32 for
operation without adjustments). Use a 20K trimming potentiometer with the wiper tied to pin 5 for zer%ffset adjustment (leave
pin 5 open for operation without adjustment).
2. Rated performance requires using good high frequency circuit
board layout techniques. The analog and digital grounds are not
connected internally. Avoid ground-related problems by connect
ing the digital and analog grounds to one point, the ground plane
beneath the converter. Due to the inductance and resistance of
the power supply return paths, return the analog and digital
ground separately to the power supplies.

ADC·508
3. Bypass all the analog and digital supplies and the + 1OV reference (pin 1) to ground with a 4.7 /!F, 25V tantalum electrolytic capacitor in parallel with a 0.1 /!F ceramic capacitor. Bypass the
+ 1OV reference (pin 1) to analog ground (pin 16). The -5V dc
supply is treated as an analog supply and analog ground (pin 16)
should be treated as its return path for decoupling purposes.
4. Obtain straight binary/offset binary output coding by tying COMP
BIN (pin 7) to +5V dc or leaving it open. The device has an internal pull-up resistor on this pin. To obtain complementary binary
or complementary offset binary output coding, tie the COMP BIN
pin to ground. The COMP BIN signal is compatible to CMOS/
TTL logic levels for those users desiring logic control of this function.
5. An overflow signal, pin 8, indicates when analog input signals are
below or above the desired full-scale range. To overflow pin also
has a three-state output and is enabled by pin 10 (Enable bits 1-5
&O.F.).

8. Over temperature, input capacitance is 50 pF maximum and input impdeance is 1. 75K minimum (2.5K typical) for unipolar and
3.75K minimum (5K typical) for bipolar. These values are guaranteed by design.
9. Requirements for ±2.5V inputs can be satisfied using DATEL's
AM-1435 amplifier in front of the SHM-45/ADC-508 configuration,
shown in Figure 3, at the appropriate gain. The SHM-45's gain of
2 mode allows 0 to +5V or ±5V input ranges.

TIMING
Figure 2 shows the relationship between the various input signals.
The timing cited applies over the operating temperature range and
over the operating power supply range. These times are guaranteed by design.

7. The drive requirements of the ADC-508 may be satisfied with a
wide-bandwidth, low output impeance input source. Applications
of these converters that require the use of a sample-hold may be
satisfied by using DATEL's model SHM-45. Using this device
with multiplexers or for test purposes will require an input buffer.

with the COMP BIN (pin 7) tied high or between 1111 1111
1111 and111111111110withtheCOMPBINtiedlow.

Removal of system errors or the small initial errors is accomplished
as follows:

3. Full-Scale Adjustment - Set the output of the voltage reference
used in step 2 to the value shown in Table 3. Adjust the gain
trimming potentiometer so that the output code flickers equally
between 1111 1111 1110 and 1111 1111 1111 for COMP BIN
(pin 7) tied high or between 0000 0000 0001 and 0000 0000
0000 for COMP BIN tied low.

1. Connect the converter per Figure 3 and Table 2 for the appropriate full-scale range (FSR). Apply a pulse of 50 nanoseconds
minimum to the START CONVERT input (pin 31) at a rate of
500 KHz. This rate chosen to reduce flicker if LED's are used
on the outputs for calibration purposes.

4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed in
Table 4.

2. Zero Adjustments - Apply a precision voltage reference source
between the analog input (pin 3) and ground (pin 16). Adjust
the output of the reference source per Table 3. For unipolar,
adjust the zero trimming potentiometer so that the output code

ADC·511
TECHNICAL NOTES

CALIBRATION

1. Applications unaffected by endpoint errors or those that remove them through software will use the typical connections
shown in Figure 2. The optional external circuitry of Figure
4 removes system errors or helps adjust the small initial errors of the ADC-511 to zero. The external adjustment circuit has no affect on the throughput rate. Table 1 shows
how to select the input range.

1. The data outputs should be connected to LED's to observe
the resulting data values. Connect the converter per Figure
2, Figure 4, and Table 1 for the appropriate Full Scale
Range (FSR). Apply a pulse of 200 nanoseconds minimum
to the START CONVERT input (pin 16) at a rate of 250
KHz. This rate is chosen to reduce flicker if LED's are used
on the outputs for calibration purposes.

2. Rated performance requires using good high frequency circuit board layout techniques.
The analog and digital
grounds are connected internally. Avoid ground-related
problems by connecting the digital and analog grounds to
one point, the ground plane beneath the converter. This
prevents contamination of the analog ground by noisy digital
ground currents.

2. Zero Adjustments
Apply a precision voltage reference source between the amplifier's signal input and analog ground. Use a very lownoise signal source for accurate calibration.
Adjust the output of the reference source per Table 4. For
unipolar operation, adjust the zero trimming potentiometer
so that the output code flickers equally between 0000 0000
0000 and 0000 0000 0001 with the COMP BIN (pin 18) tied
high or between 1111 1111 1111 and 1111 1111 1110 with
pin 18 tied low.

3. Bypass the analog and digital supplies and the + 10V reference (pin 21) to ground with a 4.7."F, 25V tantalum electrolytic capacitor in parallel with a 0.1 ."F ceramic capacitor.
Bypass the + 1OV reference (pin 21) to analog ground (pin
23).

For bipolar operation, adjust the potentiometer such that the
code flickers equally between 1000 0000 0000 and 1000
0000 0001 with pin 18 tied high or between 0111 1111 1111
and 0111 1111 1110 with pin 18 tied low.

4. Obtain straight binary/offset binary output coding by tying
COMP BIN (pin 18) to +5V dc or leaving it open. The device has an internal pull-up resistor on this pin. To obtain
complementary binary or complementary offset binary output coding, tie pin 18 to ground. The complementary signal
is compatible to CMOSITTL logic levels for those users desiring logic control of this function.

3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 4. Adjust the gain trimming potentiometer so that the output code flickers equally between 1111
1111.1110 and 1111 1111 1111 for pin 18 tied high or between 0000 0000 0001 and 0000 0000 0000 for pin 18 tied
low.

5. To obtain Three-State outputs, connect ENABLE (pin 17) to
a logic "0" (low). Otherwise, connect pin 17 to a logiC "1"
(high).

To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 6.

TIMING
Figure 3 shows the relationship between the various input signals. The timing shown applies over the operating temperature
range and over the operating power supply range. These
times are guaranteed by design.

GENERAL DESCRIPTION

MECHANICAL DIMENSIONS
INCHES (mm)

DATEL's ADC-520 and ADC-521 are 12-bit analog-to-digital
converters with conversion speeds of up to 800
nanoseconds. Both models are identical except for the
analog input voltage ranges.

The performance of these converters is based upon a
digitally-correcting subranging architecture. DATEL further
enhances this technology by using unique laser trimming
schemes. The ADC-520 and ADC-521 are packaged in a
32-pin ceramic DIP and consume 1.6 watts.

1. Use external potentiometers to remove system errors or
the small initial errors to zero. Use a 20K ohm trimming
potentiometer for gain adjjustment with the wirper tied to
pin 27 (ground pin 27 for operation without adjustments).
Use a 20K ohm trimming potentiometer with the wiper
tied to pin 19 for zer%ffset adjustment (leave pin 19
open for operation without adjustment).

2. Rated performance requires using good high frequency circuit
board layout techniques. The analog and digital grounds are not
connected internally. Avoid ground-related problems by connecting the digital and analog grounds to one pOint, the ground plane
beneath the converter. Due to the inductance and resistance of
the power supply return paths, return the analog and digital
ground separately to the power supplies.
3. Bypass all the analog and digital supplies and the + 1OV reference (pin 18) to ground with a 4.7 I-lF, 25V tantalum electrolytic
capacitor in parallel with a O.II-lF ceramic capacitor. Bypass the
+ 1OV reference (pin 18) to analog ground (pin 32) the same way.
4. QQ.tain straight binary/offset binary output coding by tying CaMP
BIN (pin 7) to +5V de or leaving it open. The device has an internal pull-up resistor on this pin. To obtain complementarv binary
or complementary offset binary output coding, tie the CaMP BIN
pin to ground. In the bipolar mode, two's complement QUlputcoding.is available by using the MSB output (pin 13). The CaMP
BIN signal is compatible to CMOSmL logic levels for those users desiring logic control of this function.
5. Enable the three-state outputs by connecting ENABL~n 14) to
a logic 0 (low). The ENABLE signal has no effect on MSB (pin
13) which is not a three-state output and therefore is not controlled by the enable pin.
6. Satisfy high-speed drive requirements of the ADC-520, -521 with
a wide-bandwidth, low output impedance input source such as
DATEL's SHM-45 sample-and-hold or AM-1435 amplifier.
7. The ADC-520,-521 provide an internal buffer amplifier. Using
this buffer provides an inut impedance of 1012 ohms, allowing
the AID to be driven from a high impedance source or directly
from an analog multiplexer. When using the input buffer, allow a
delay equal to its settling time between input level change and
the negative going edge of the START CONVERT pulse. If the
buffer is not required, its input should be connected to analog
ground to avoid introducing noise into the converter.

Figure 2 shows the relationship between the various input signals.
The timing cited applies over the operating temperature range and
over the operating power supply range. These times are guaranteed by design.

CALIBRATION PROCEDURE
1. Connect the converter per Figure 3 and Tables 2a and 2b for
the appropriate full-scale range (FSR). Apply a pulse of 50 nanoseconds minimum to the START CONVERT input (pin 21) at a
rate of 500 KHz. This rate reduces flicker if LED's are used on
the outputs for calibration purposes.
2. Zero Adjustments - Apply a precision voltage reference source
between the analog input and ground. Refer to Tables 2a and
2b for the correct input pin. Adjust the output of the reference
source per Table 3. For unipolar, adjust the zero trimming potentiometer so that the output code flickers equally between
0000 0000 0000 and 0000 0000 0001 with the COMP BIN (pin
17) tied high (straight binary) or between 1111 1111 1111 and
1111 1111 1110 with the COMP BIN tied low (complementary
binary).
For bipolar operation, adjust the potentiometer such that the
code flickers eQually between 1000 0000 0000 and 1000 0000
0001 with COMP BIN (pin 17) tied high (offset binary) or between 0111 1111 1111 and 0111 1111 1110 with COMP BIN
(pin 17) tied low (complementary offset binary).

2-31

ADC·S20,ADC·S21
Two's complement and complementary two's complement requiresthe use of MSB (pin 13) versus MSB (pin 12) as given for
offset binary or complementary offset binary respectively.
3. Full-Scale Adjustment - Set the output of the voltage reference
used in step 2 to the value shown in Table 3. Adjust the gain
trimming potentiometer 50 that the output code flickers eoually
between 111111111110and 111111111111 forCOMPBIN
(pin 17) tied high or between 0000 0000 0001 and 0000 0000
0000 for COMP BIN tied low. Two's complement and ~Ie­
mentary two's complement respectively requires using MSB, pin
13.
4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed in
Tables 4 and 5.

ADC-530
All digital inputs and three-state outputs are TTL- and CMOScompatible. Output coding can be in straight binary/offset binary or complementary binary/complementary offset binary by
using the COMP BIN pin. An overflow pin indicates when inputs are below or above the normal full-scale range.
A novel feature of the ADC-530 is the provision of a Sample/
ROld control pin for applications where a sample-hold is used
in conjunction with the ADC-530. This feature allows the sample-and-hold device to go back into the sample mode a minimum of 30 nanoseconds before the conversion is complete,
improving the overall conversion rate of the system.

1. Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 20K trimming potentiometer for gain adjustment with the wiper tied to pin 32 (ground
pin 32 for operation without adjustments). Use a 20K trimming potentiometer with the wiper tied to pin 5 for zero/
offset adjustment (leave pin 5 open for operation without adjustment).
2. Rated performance requires using good high frequency circuit board layout techniques.
The analog and digital
grounds are not connected internally. Avoid ground-related
problems by· connecting the digital and analog grounds to
one point, the ground plane beneath the converter. Due to
the inductance and resistance of the power supply return
paths, retun tAe analog and digital ground separately to the
power supplies.

3. Bypass all the analog and digital supplies and the +10V reference (pin 1) to ground with a 4.7 l1F, 25V tantalum electrolytic capacitor'in parallel with a 0.1 l1F ceramic capacitor.
Bypass the + 1OV reference· (pin 1) to analog ground (pin
16).

4. Obtain straight binary/offset binary output coding by tieing
CoMpSTIii (pin 7) to +5V dc or leaving it open. The device
has an internal pull-up resistor on this pin. To obtain complementary bin~.()i~omplementary offset bin~ry_().u!!>!Jt
coding tie the COMP BIN pin to ground. The COMP BIN
signal is compatible to CMOS/TTL logic levels for those users desiring logic control of this function.

CALIBRATION PROCEDURE

5. An overflow signal, pin 8, indicates when analog input signals are below or above the desired full-scale range. The
overflow pin also has a three-state output and is enabled by
pin 10 (ENABLE bits 1-5 & O.F.).

2. Zero Adjustments
Apply a precision voltage reference source between the analog input (pin 3) and ground (pin 16). Adjust the output of
the reference source per Table 3. For unipolar, adjust the
zero trimming potentiometer so that the output code flickers
equally between 0000 0000 0000 and 0000 0000 0001 with
the COMP BIN (pin 7) tied high or between 1111 1111 1111
and 111111111110 with pin 7 tied low.

6. The sample-and-hold (S/H) control signal, pin 17, goes low
following the rising edge of a start convert pulse and high 30
nanoseconds minimum before EOC goes low. This indicates that the converter can accept a new analog input.
7; The drive requirements of the ADC-530 may be satisfied
with a wide-bandwidth, low output impedance input source.
Applications of these converters that require the use of a
sample-and-hold may be satisfied by using DATEL's model
SHM-45 .. Using this device with multiplexers or for test purposes will require an input buffer.
8. Over temperature, input capacitance is 50 pF maximum and
input impedance is 1.75K minimum (2.5K typical) for a to
+10V and 3.75K minimum (5K typical) for a to +20V, ±10V.
These values are guaranteed by design.
9. Requirements for ±2.5V inputs can be satisfied using DATEL's AM-1435 amplifier in front of the SHM-45/ADC-530
configuration, shown in Figure 3, at the appropriate gain.
The SHM-45's gain of 2 mode allows a to +5V or ±5V input
ranges.

1. Connect the converter per Figure 3 and Table 2 for the appropriate full-scale range (FSR). Apply a pulse of 100 nanoseconds minimum to the START CONVERT input (pin 31)
at a rate of 500 KHz. This rate is chosen to reduce flicker if
LED's are used on the outputs for calibration purposes.

For bipolar operation, adjust the potentiometer such that the
code flickers equally between 1000 0000 0000 and 1000
0000 0001 with pin 7 tied high or between 0111 1111 1111
and011111111110withpin7tiedlow.
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 3. Adjust the gain trimming potentiometer so that the output code flickers equally between 1111
1111 1110 and 1111 1111 1111 for pin 7 tied high or between 0000 0000 0001 and 0000 0000 0000 for pin 7 tied
low.
4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Table 4.

TIMING
Figure 2 shows the relationship between the various input signals. The timing cited applies over the operating temperature
range and over the operating power supply range. These
times are guaranteed by design.

ADC-908
TECHNICAL NOTES
1. Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 20K trimming potentiometer for gain adjustment with the wiper tied to pin 6 (ground
pin 6 for operation without adjustments). Use a 20K trimming potentiometer with the wiper tied to pin 5 for zero/
offset adjustment (ground pin 5 for operation without adjustment).
2. Rated performance requires using good high-frequency circuit board layout techniques. The analog and digital
grounds are not connected internally. Avoid ground-related
problems by connecting the digital and analog grounds to
one point, the ground plane beneath the converter. Due to
the inductance and resistance of the power supply return
paths, return the analog and digital ground separately to the
power supplies.
3. Bypass the analog and digital supplies and the +1 OV reference (pin 1) to ground with a 4.7 J.lF, 25V tantalum electrolytic capacitor in parallel with a 0.1 J.lF ceramic capacitor.
Bypass the +1 OV reference (pin 1) to analog ground (pin
15).

4. Obtain straight

binar~offset

binary or 2'8 complement output
coding by tying C(}P BIN (pin 8) to +5V dc or leaving it
open. The device has an internal pull-up resistor on this
pin. To obtain complementary binary, complementary off
set binary, or complementary 2's complement output coding,
tie pin 8 to ground. The COMP BIN signal is compatible to
CMOSITTL logic levels for those users desiring logic control
of this function.

5. To enable the three-state outputs, connect ENABLE (pin 9)
to a logic "0" (low). To disable, connect pin 9 to a logic "1"
(high).

~~

ANALOG
INPUT

6. The SAMPLE/HOLD CONTROL, pin 14, is low on power-up.
The START CONVERT pulse should be given at a time delay equal to the desired acquisition time minus th...!!. 10 nanosecond delay from START CONVERT high to S/H CONTROL high. This assures the sample-hold has the minimum
required acquisition time for the particular application mode.
The SAMPLE/HOLD CONTROL pin goes high following the
rising edge of a START CONVERT pulse and low 30 nanoseconds minimum before EOC goes low. This indicates the
converter can accept a new analog input.
7. Retriggering the START CONVERT pulse before EOC goes
low will not initiate a new conversion.

CALIBRATION PROCEDURE
1. Connect the converter per Figure 3, and Table 1 for the appropriate full-scale range (FSR). Apply a pulse of 200 nanoseconds minimum to the START CONVERT input (pin 31)
at a rate of 250 KHz. This rate is chosen to reduce flicker if
LED's are used on the outputs for calibration purposes.
2. Zero Adjustments
Apply a precision voltage reference source between the analog input (pin 3) and ground (pin 4). Adjust the output of
the reference source per Table 2.
For unipolar, adjust the zero trimming potentiometer so that
the output code flickers equally betwelllLOO 0000 0000
0000 and 00 0000 0000 0001 with the COMP BIN (pin 8)
tied high (straight binary) or between 11 1111 1111 1111
and 11 1111 1111 1110 with pin 8 tied low (complementary
binary).

For bipolar operation, adjust the potentiometer such that the
code flickers equally between 10 0000 0000 0000 and 10
0000 0000 0001 with pin 8 tied high (offset binary) or between 01 1111 11111111 and 01 1111 1111 1110 with pin
8 tied low (complementary offset binary).
Two's complement coding requires use of the MSB (pin 31)
with pin 8 tied high, adjusting the potentiometer such that
the code flickers between 00 0000 0000 0000 and 00 0000
0000 0001.
3. Full-Scale Adjustment
Set the output of the voltage reference used in step 2 to the
value shown in Table 2.
Adjust the gain trimming potentiometer so that the output
code flickers equally between 11 1111 1111 1110 and 11
1111 1111 1111 with pin 8 tied high (straight binary) or between 00 0000 0000 0000 and 00 0000 0000 0001 pin 8
tied low (complementary binary).
Two's complement coding requires use of the MSB (pin 31)
with the pin 8 tied high, adjusting the gain trimming potentiometer so that the output code flickers equally between 01
1111 1111 1110 and 01 1111 1111 1111.
4. To confirm proper operation of the device, vary the precision
reference voltage source to obtain the output coding listed
in Tables 3 and 4.

CMOS and TIL logic are not compatible. due to different
threshold levels. They can, however, be interfaced by
simple techniques.
The START CONVERT (Pin 21) can be driven directly
from an open collector, high voltage TIL gate. Resistor
Rx is used to source current and bring the TIL output up
to the CMOS threshold level. Typical values of Rx are
3.3K to 10K ohms.
CMOS to TTL interface requires sufficient sink current
in the low state. The CD4049 (inverting) and CD4050
(noninverting) buffers, powered from +5V logic supply
can accept input voltage swings of +5 to + 15V from the
CMOS system. Each buffer gate can drive at least one input from any TTL family.

GENERAL DESCRIPTION
The ADC-HS12B is a high performance 12-bit hybrid AID
converter with a self-contained sample-hold. It is specifically
designed for systems applications where the sample-hold is
an integral part of the conversion process. The internal
sample-hold has a 6 microseconds acquisition time for a full
10V dc input change; the AID converter has a fast 9
microseconds conversion time. Five· input voltage ranges
are programmable by external pin connection; 0 to +5V, 0
to+10V, ±2.5V, ±5V, and ±10V. Input impedance to the
sample-hold is 100 megohms. Output coding is
complementary binary for unipolar operation and
complimentary offset binary for bipolar operation, with both
parallel and serial outputs brought out.

TECHNICAL NOTES
1. It is recommended that the t15V power input pins both be
bypassed to ground with a 0.01 ~F ceramic capacitor in parallel with a 1 ~F electrolytic capaCitor and the +5V power input pin be bypassed to ground with a 1 ~F electrolytic capacitor as shown in the connection diagrams. In addition, pin 27
should be bypassed to ground with a 0.01 ~F ceramic capacitor. These precautions will assure noise free operation
of the converter.
2. Digital Common (pin 15) and Analog Common (pin 26) are
not connected together internally, and therefore must be
connected as directly as possible externally. It is recommended that a ground plane be run underneath the case between the two commons. Analog ground and t15V power
ground should be run to pin 26 whereas digital ground and
+5V dc ground should be run to pin 15.

Clock Output ................ Train of positive going +5V, 100

3. External adjustment of zero or offset and gain are provided
for by trimming potentiometers connected as shown in the
connection diagrams. The potentiometer values can be between 10K and lOOK ohms and should be 100 ppml ·C, cermet types. The adjustment range is to.5% of FSR for zero
or offset and ±0.3% for gain. The trimming pots should be
located as close as possible to the converter to avoid noise
pickup. Calibration of the ADC-HS12B is performed with the
sample-hold connected and operating dynamically. This results in adjusting out the sample-hold errors along with the
AID converter. For slow throughput applications it is recommended that a 0.01 ~F hold capacitor be used for best accuracy. With this value the acquisition time becomes 25 microseconds and the external timing must be adjusted
accordingly.

5. Short cycled operation results in shorter conversion times
where the conversion can be truncated to less than 12 bits.
This is done by connecting pin 14 to the output bit following
the last bit desired. For example, for an 8-bit conversion, pin
14 is connected to bit 9 output. Maximum conversion times

6. Note that output coding is complementary coding. For unipolar operation it is complementary binary and for bipolar
operation it is complementary offset binary. In cases where
bipolar coding of offset binary is required, this can be
achieved by inverting the analog input to the converter (using
an operational amplifier connected for gain of -1.0000). The

CONVERT (Pin 21). The rate of the external clock must be
lower than the rate of the internal clock. The pulse width of
the external clock should be between 100 nanoseconds and
300 nanoseconds. Each N bit conversion cycle requires a
pulse train of N + 1 clock pulses for completion, e.g., an
8-bit conversion requires 9 clock pulses for completion. A
continuous pulse train may be used for consecutive conversions, resulting in an N bit conversion every N + 1 pulses, or
the E.O.C. output may be used to gate a continuous pulse
train for single conversions.

7. These converters dissipate 1.81 watts maximum of power.
The case to ambient thermal resistance is approximately
25°C per watt. For ambient temperatures above 50°C, care
should be taken not to restrict air circulation in the vicinity of
the converter.
8. These converters can be operated with an extemal clock. To
accomplish this, a negative pulse train is applied to START

CALIBRATION PROCEDURE
1. Connect the ADC-HS12B as shown in one of the connection
diagrams. The sample-hold and AID converter should be
timed as shown in the timing diagram. The trigger pulse
should be applied at a rate of 70kHz or less and should be
100 nanoseconds minimum width.
2. Zero and Offset Adjustments
Apply a precision voltage reference source between the
selected analog input and ground. Adjust the output of the
reference source to the value shown in the Calibration Table
for the unipolar zero adjustment (zero + % LSB) or the
bipolar offset adjustment (- FS + % LSB). Adjust the trimming potentiometer so that the output code flickers equally
between 1111 1111 1111 and 1111 1111 1110.
3. Full Scale Adjustment
Change the output of the precision voltage reference source
to the value shown in the Calibration Table for the unipolar or
bipolar gain adjustment (+ FS - 1% LSB). Adjust the gain
trimming potentiometer so that the output code flickers
equally between 0000 0000 0001 and 0000 0000 0000.

GENERAL DESCRIPTION
The ADC-HX12B and ADC-HZ12B are self-contained, high
performance, 12-bit AID converters manufactured with
thick-and thin-film hybrid technology. They use the
successive approximation conversion technique to achieve
a 12-bit conversion in 20 and S microseconds respectively.
Five input voltage ranges are programmable by external pin
connection: 0 to +5V, 0 to +10V, ±2.5V, ±5V, and ±10V. An
internal buffer amplifier is also provided for applications
where 100 megohm input impedance is required.

These converters utilize a fast 12-bit monolithic DAC which
includes a precision zener reference source. The circuit also
contains a fast monolithic comparator, a monolithic 12-bit
successive approximation register, a clock and a monolithic
buffer amplifier. Nonlinearity is specified at ±'/2 LSB
maximum.

Both models have identical operation except for conversion
speed. They can be short-cycled to give faster conversion in
lower resolution applications. Use of the internal buffer
amplifier increases conversion time by 3 microseconds, the
settling time of the amplifier. Output coding is
complementary binary, complementary offset binary, or
complementary two's complement. Serial data is also
brought out. The package is a 32-pin ceramic case.

GENERAL DESCRIPTION
The DAC-HK Series hybrid D/A converters are high
performance 12-bit devices with a fast settling voltage
output. They incorporate a level controlled input storage
register and are specifically designed for systems
applications such as data bus interfacing with computers.
When the "load" input is high, data in the storage register is
held and when the load input is low, date is transferred
through to the DAC. There are two basic models available
by coding option: binary, and two's.complement. The output
voltage ranges are externally pin-programmable and
include: 0 to +2.5V, 0 to +5V, 0 to +10V, ±2.5V, ±5V, and
±10V.

The DAC-HK Series contains a precision zener reference
circuit. This eliminates code-dependent ground currents by
routing current from the positive supply to the internal
ground node a determined by the R-2R ladder network. The
internal feedback resistors for the on-board amplifier track
the ladder network resistors, enhancing temperature
performance. The excellent tracking of the resistors results
in a differential nonlinearity tempco of 2 ppm/DC maximum.
The temperature coefficient of gain is 20 ppm/DC maximum
and tempco of zero is ±3 ppm/DC maximum.

TECHNICAL NOTES
1. It is recommended that these converters be operated with
local supply bypass capacitors of 1 fl-F (tantalum type) at the
+ 15, - 15, and + 5V supply pins. The capacitors should be
connected as close to the pins as possible. In high RFI noise
environments these capacitors should be shunted with 0.01
fl-F ceramic capacitors.
2. The analog, digital, and power grounds should be separated
from each other as close as possible to pin 21 where they all
must come together.
3. The "load" control pin is a leveltriggered input which causes
the register to hold data with a high input and transfer data to
the· DAC with a low input.
4. A setup time of 50 nanoseconds minimum must be allowed
for the input data. The DAC output voltage begins to change
when the register output changes.
5. The external gain adjustment shown in the Connection
Diagrams has a range of ± 0.2% of full scale. If a wider range
is desired the 18-Megohm resistor can be decreased slightly
in value. The fUll-scale output is typically accurate within
± 0.1 % with no adjustment. The zero, or .offset, adjustment
has a range of ± 0.35% of FS.
6. If the reference output terminal (pin 24) is used, an operational amplifier in non-inverting mode should be used as a
buffer. Current drawn from pin 24 should be limited to ± 10
~ in order not to affect the T.C. of the reference.

The DAC-HZ Series contains a precision zener reference
circuit. This eliminates code-dependent ground currents by
routing current from the positive supply to the internal
ground node as determined by the R-2R ladder network.
The internal feedback resistors for the on-board amplifier
track the ladder network resisters, enhancing temperature
performance. The excellent tracking of the resistors results

1. A printed circuit board with ground plane is recommended
for best performance. The supply pins (pins 5, 9) should
be bypassed to ground with a 0.01 to 0.1 I1F ceramic capaCitor as close to the pins as possible.

3. The Hold Capacitor (CH) should have high insulation resistance and low dielectric absorption to minimize droop error.
For operating temperatures up to +70 °C, polystyrene dielectric is a good choice. Any PC connections to the hold
capaCitor terminal (pin 11) should be kept short and "guarded" by the ground plane to avoid errors due to drift currents
from nearby signal lines or power supply voltages.
4. The offset adjust may be used to eliminate the pedestal error by connecting a 10K ohm pot between pins 3 and 4
and connecting the wiper to the -15V supply, pin 5.

The SHM-45 is a complete sample-hold circuit, containing a
precision MOS hold capacitor and a MOSFET switching
configuration which results in faster switching and better
feedthrough attenuation. Additionally, an FET input amplifier
design allows faster acquisition and settling times while
maintaining a considerably lower droop rate.

Input signal times gain.should not exceed the output voltage range.
2. The SHM-45 output is current limited at approximately
±65 mAo The device can withstand a sustained short to
ground. However, shorts to either supply will cause permanent damage.
3. Sample-to-Hold offset error (Pedestal) is constant regardless of input/output level.
4. FS is defined as 10 Volts.

TECHNICAL NOTES
1. All ground pins (10, 15, 21, 23) should be tied together
and connected to system analog ground as close to the
package as possible. It is recommended to use a
ground plane under the device and solder all four ground
pins directly to it. Care must be taken to insure that no
ground potentials can exist between pin 10 and the other
ground pins.

Although the power supply pins (9, 22, 24) are internally
bypassed to ground with 0.01 ~F ceramic capacitors, additional external 0.1 ~F to 1 ~F tantalum bypass capacitors may be required in critical applications.

3.

A logiC 1 on the HOLD COMMAND input, pin 12 will put
the device in the sample mode. In this mode, the device
acts as an inverting unity gain amplifier and its output will
track its input. A logic 0 on pin 12 will put the device in
the hold mode, and the output will be held constant at
the last input level present when the hold command was
given.

4.

The maximum capacitive load to avoid oscillation is typically 250 pF. Recommended resistive load is 500n, although values as low as 250n may be used. Acquisition
and sample-to-hold settling times are relatively unaffected by resistive loads down to 250n and capacitive loads
up to 50 pF. However, higher capacitances will affect
both acquisition and settling time.

5.

TAe RANGE pin of the SHM-45 is usable to select different output voltage ranges. The output voltage ranges
are selectable by hardware programming the SHM-45 to
operate at different gains. Table 1 shows the range selection details.

The SHM-4860 is a complete sample-hold circuit, containing a precision MOS hold capacitor and a MOSFET
switching configuration which results in faster switching and
better feedthrough attenuation. Additionally, an FET input
amplifier design allows faster acquisition and settling times
while maintaining a considerably lower droop rate.

TECHNICAL NOTES
1. All ground pins (10, IS, 21, 23) should
be tied together and connected to system analog ground as close to the
package as possible. It is recommended to use a ground plane under
the device and solder all four ground
pins directly to it. Care must be taken to
insure that no ground potentials can exist between Pin 10 and the other
ground pins.
2. Although the power supply pins (9, 22,
24) are internally bypassed to ground
with 0.01 p.F ceramic capacitors, additional external 0.1 p.F to 1 p.F tantalum
bypass capacitors may be required in
critical applications.
3. A logic "0" on the HOLD COMMAND
INPUT, (Pin 11) (or a logic "1" on the
HOLD COMMAND INPUT, Pin 12) will
put the device in the sample mode. In
this mode, the device acts as an inverting unity gain amplifier and its output
will track its input. A logic" 1" on Pin 11
(logic "0" on Pin 12) will put the device
in the HOLD mode, and the output will
be held constant at the last input level
present when the hold command was
given.
If the HOLD COMMAND INPUT (Pin
11) is used to control the device, Pin 12
must be tied to digital ground. If HOLD
COMMAND INPUT (Pin 12) is used to
control the device, Pin 11 must be tied
to +5V.
4. The maximum capacitive load to avoid
oscillation is typically 250 pF. Recommended resistive load is 5000,
although values as low as 2500 may be
used. Acquisition and sample-to-hold
settling times are relatively unaffected
by resistive loads down to 2500 and
capacitive loads up to 50 pF. However,
higher capacitances will affect both acquisition and settling time.

2. The SHM-4860's output is current limited at approximately ±65 mAo The device
can withstand a sustained short to ground. However, shorts from the output to either supply will cause permanent damage. For normal operation the load current
should not exceed ±40 mAo
3. Fulll Scale (FS) =10V. Full Scale Range (FSR) =20V.

TECHNICAL NOTES
·1. The. use of good high Jrequency circuit board layout techniques is required for rated performance. The power common, analog common, and input common pins are not
connected internally and therefore must be connected externally as directly as possible thorugh a low inductance,
low resistance path. The extensive use of a ground plane
for all common connections is highly recommended.
2. Although they are internally bypassed with 0.033 IlF capacitors the supply pins should be externally bypassed
with 0.1 IlF ceramic Chip capacitors mounted as close to
the supply pins as possible.
3. The SHM-7 inputs and outputs are sensitive to unusual
loading or long lines. The analog input must be nonreactive so that leads should be short and purely resistive.
Also, the complementary ECl driver should be as close as
possible to pins 1 and 3 to minimize lead lengths to these
pins.
4. The maximum, differential, digital input voltage is ±5V.
For example, if pin 3 is at a potential of -5V, pin 1 may not
exceedOV.

2. Tested at ±25 °C with input source impedance of 50 ohms.

TECHNICAL NOTES
1. All ground pirrs (2, 12, 14,24) should be tied together and
connected to system analog ground'as close to. the pack'"
age as possible. It is recommended to use a ground plane
under the device and solder all four ground pins directly to
it. Tne,power supply pins (5, 6, 17, 18) should be bypassed
to analog ground with .01 ,.u= ceramic capacitors locatea as
close to tha pins as possible. In certain critical applications,
additional bypass precautions using 0.1 or 1.0 I'F tantalum
capacitors are suggested.
2. A logic "I" on the sample pins (9, 21).will put this device in
the sample l']1ode.ln this mode, the device acts as an unity
gain amplifier and its output will track its input. A logic "0"
on the sample pins (9, 21) will put the device in the hold
mode, and the ;)utput will be held constant at the last input
level present before- the hold command was given.
3. Care should be taken when using tbe mu!!!2lexeroutput pins
(11,23) that the A EN (pin 7) and the B'EN.(pin 19) are not
active (logic 0) at the same time. This condition could possibly damage the device.
4. The output of the SHM-91 should drive a high impedance
receiver to minimize voltage divider losses. The receiver
input impedance should be lOOK ohms or greater when using the direct outputs from the amplifiers (pins 1 and 13). The
receiver input impedance should be 2.5 M ohms or greater
when using the multiplexer outputs (pins 11 and 23).
5. The SHM-91 should not be left in the hold mode for long peri·
ods of time. It should be left in the sample mode when long
or indeterminate peFiods of time are involved. If left in the
hold mode for several seconds, the output will continue to
"droop" toward the power supply voltage. Eventually the output amplifier will saturate. The unit will require longer than
the specified acquistion time to acquire a signal when the
output amplifiers are saturated.
6. A Logic "I" on the A or B ADDR (Address) pins (8 and 20)
will select channel 1A or 1 B on the respective input mux.
A Logic "0" will select 2A or 2B.

NOTE: Pins have 0.025 Inch ±0.01

3. Differential amplifier - high·resolution applications frequently require the
ability to sense ground at a distant signal source. To avoid errors due to
different ground potential, use the SHM-945's analog input low (pin 10) to

sense the ground at the signal source.

In noisy applications, using shielded

twisted pair wire, with one end of the shield tied to ground at the sample/hold,
is recommended. Analog Input Low and Range Return (when used) must be
S; tOO mV maximum with respect to Analog Ground.

Through the use of thin-film hybrid construction, this ultra
high-speed circuit is contained in a miniature 24-pin ceramic
package. A 53 picofarad MaS hold capacitor is incorporated inside the package and provision is made for externally added capacitance when necessary. The sample-hold
requires four external resistors and an lH0033 fast buffer
amplifier for completion. The circuit is zeroed by adjustment
of the lH0033 amplifier.

be bypassed with the same value capacitors.
2. It is essential that the output lead from pin 18 to pin 5 of the
lH0033 be kept as short and direct as possible. Also, the
complementary ECl driver should be as close as possible to
pins 1 and 3 to minimize lead lengths to these pins.

I. One TTL load is defined as sinking 40 IlA with a logic I input and·
sourcing 1.6mA with a logic 0 input
2. Full Scale (FS) = 10V. Full Scale Range (FSR) = 20V.
3. Sample-la-Hold offset error (Pedestal) is constant regardless of inpuVoulput level.

TECHNICAL NOTES
1. All ground pins should be tied together and connected to system analog
ground as close to the package as possible. It is recommended to use a
ground plane under the device and solder ground pins directly to it Care
must be taken to insure that no ground potentials can exist between ground
pins,
2. External 0.1

~F

to 1 ~F tantalum bypass capacitors are required in critical ap-

plications.

3. A logic 1 on SIH puts the unit in the track mode. A logic 0 puts the unit in
hold mode.
4. The maximum capacitive load to avoid oscillation is typically 250 pF, Recommended resistive load is 500n, although values as low as 250n

may be

used, Acquisition and sample-to-hold settling times are relatively unaffected
by resistive loads down to 2500 and capacitive loads up to 50 pF. However,
capacitances will affect both acquisition and settling time,

INPUT VOLTAGE PROTECTION
As shown in Figure 3, the multiplexer has reversed biased diodes
which protect the input channels from being damaged by overvoltage signals. The HDAS input channels are protected up to 2f1II
beyond the supplies and can be increased by adding series resistors (Ri) to each channel. The input resistor must limit the current
flowing through the protection diodes to 10 mAo

GENERAL DESCRIPTION
The HDAS-524,-528 are complete data acquisition systems
containing an internal multiplexer, instrumentation amplifier,
sample-hold, analog-to-digital converter and three-state outputs. Packaged in a miniature 40-pin double-dip package, the
HDAS-524/528 has a low power dissipation of 2.6 watts.
The HDAS-524 provides 4 differential inputs and the HDAS528 provides 8 single-ended inputs. An internal instrumentation amplifier is characterized for gains of 1,2,4,8,10 and 100.
The gain range is selectable through an external resistor.

TECHNICAL NOTES
1. Rated performance requires using good high-frequency
circuit board layout techniques. The analog and digital
grounds are not connected internally. Avoid groundrelated problems by connecting the analog, signal and digital grounds to one point, the ground plane beneath the
converter. Due to the inductance and resistance of the
power supply return paths, return the analog and digital
ground separately to the power supplies. This prevents
contamination of the analog ground by noisy digital ground
currents.
2. Double-level multiplexing allows expanding the multiplexer channel capacity of the HDAS-528 from 8 singleended channels to 128 single-ended channels or the
HDAS-524 from 4 differential channels to 32 single-ended
channels.

The acquisition time is the amount of time the multiplexer, instrumentation amplifier and sample-hold require to settle
within a specified range of ~racy; The acquisition time can
be measured by how long EOC is low before the rising edge
of the START CONVERT pulse for continuous operation.
Higher gains require the use of the RGAIN resistor to increase the acquisition time. The gain is equal to 1 without an
RGAIN resistor. Table 2 refers to the appropriate RGAIN resistors for various throughputs.

The HDAS devices enter the hold mode and are ready for
conversion upon the start convert going high. The con~ion
is complete within a maximum of 800 nsec ( + 25°C). EOC
returns low, the data is valid and sent to the three-state output
buffers. The sample/hold is now ready to acquire new data.

1. Connect the converter per Figure 2 and Tables 2 and 3 for
the appropriate full-scale range (FSR). Apply a pulse of 100
nanoseconds (typical) to the START CONVERT input (pin 40)
at a rate of 100 KHz. This rate is chosen to reduce flicker if

The HDAS-534 provides 4 differential inputs and the HDAS538 provides 8 single-ended inputs. An internal instrumentation amplifier is characterized for gains of 1,2.4,8,10 and 100.
The gain range is selectable through an external resistor.

TECHNICAL NOTES
1. Rated performance requires using good high-frequency circuit board layout techniques. The analog and digital grounds
are not connected internally. Avoid ground-related problems
by connecting the analog, signal and digital grounds to one
pOint, the ground plane beneath the converter. Due to the inductance and resistance of the power supply return paths, return the analog and digital ground separately to the power
supplies.

The acquisition time is the amount of time the multiplexer, instrumentation amplifier and sample· hold require to settle
within a specified range of accuracy.
The acquisition time can be measured by how long EOC is
low before the rising edge of the START CONVERT pulse for
continuous operation. Higher gains'require the use of the
RGAIN resistor to increase the acquisition time. The gain is
equal to 1 without an RGAIN resistor. Table 2 refers to the
appropriate RGAIN resistors for various throughputs.
The HDAS devices enter the hold mode and are ready for
conversion upon the start convert going high. The c~rsion
is complete within a maximum of 1 f1sec (+25°C). EOC returns low, the data is valid and sent to the three-state output
buffers. The sample/hold is now ready to acquire new data.

1. Connect the converter per Figure 2 and Table 2 for tbe appropriate full-scale range (FSR). Apply a pulse of 150 nSec
(typical) to the START CONVERT input (pin 40) at a rate of
75 KHz. This rate is chosen to reduce flicker if LED's are used
on the outputs for calibration purposes.

~ I
0.150(3,8)Min.=

The HDAS-76 provides 4 differential inputs and the HDAS-75
provides 8 single-ended inputs. An internal instrumentation
amplifier is characterized for gains of 1,2,4,8,10 and 100. The
gain range is selectable through an external resistor.

TECHNICAL NOTES
1. Rated performance requires using good high-frequency circuit board layout techniques, The analog and digital grounds
are not connected internally. Avoid ground-related problems
by connecting the analog, signal and digital grounds to one
pOint, the ground plane beneath the converter. Due to the inductance and resistance of the power supply return paths, return the analog and digital ground separately to the power
supplies.

Table 2. Input Range Parameters

HDAS-75176 OPERATION
The HDAS devices accept either 8 single-ended or 4 differential input signals. Tie unused channels to SIGNAL GROUND,
pin 14.
Channel selection is accomplished using the multiplexer address pins shown in Table 1. Obtain additional channels by
connecting external multiplexers.
The acquisition time is the amount of time the multiplexer, instrumentation amplifier and sample-hold require to settle within
a specified range of accuracy aiter the start convert goes high.
The acquisition time can be measured by how long EOC is
low before the rising edge of the START CONVERT pulse for
continuous operation. Higher gains require the use of the
RGAIN resistor to increase the acquisition time. The gain is
equal to 1 without an RGAIN resistor. Table 2 refers to the
appropriate RGAIN resistors for various throughputs.

1110and 111111111111.
4. To confirm proper operation of the device, vary the precision reference voltage source to obtain the output coding listed in Table 4.

resistors.
CALIBRATION PROCEDURE
1. Connect the converter per Figure 2 and Tables 2 and 3 for
the appropriate full-scale range (FSR). Apply a pulse of 1,0
llSec (typical) to the START CONVERT input (pin 40) at a
rate of 75 KHz. This rate is chosen to reduce flicker if LED's
are used on the outputs for calibration purposes.

TIMING

EOC

The
output signal, when high, indicates that a conversion
is in process. During a conversion the digital output buffers
are in a high impedance state, preventing data from being
read. A START CONVERT input received during a conversion
has no effect on the existing conversion. As shown in Figurela, data can be read while START CONVERT is high and
EOC is low.

START

CONVERT
EOC

The AID conversion begins on the falling edge of a start convert command. If START CONVERT stays low after EOC becomes low, the output buffers stay in a high impedance state.
Valid data can be read 150 nanseconds maximum after
START CONVERT goes high. Figure 1b shows how to use
the START CONVERT pulse to. control when the output data

becomes valid.

HDAS-950/-951
16-Bit, 100 KHz
Data Acquisition Systems

PRELIMINARY PRODUCT DA TA
FEATURES
• 16-8it resolution, 100 KHz

• 8 Channels single-ended or 4 channels differential
• Miniature 40-pin DDIP
• Full-scale gain range from 100 mV to 10V
• High-impedance output state

GENERAL DESCRIPTION
The HDAS-950/-951 are complete data acquisition systems
containing an internal multiplexer, instrumentation amplifier,
sample-hold, analog-to-digital converter and three-state outputs. Packaged in a miniature 40-pin double-dip package, the
HDAS-950/-951 have a low power dissipation of 2.4 watts.
The HDAS-951 provides 4 differential inputs and the HDAS950 provides 8 single-ended inputs. An internal instrumentation amplifier is characterized for gains of 1, 2, 4, 8, 10 and
100. the gain range is selectable using an external resistor.
TECHNICAL NOTES
1. Use external potentiometers to remove system errors or the
small initial errors to zero. Use a 20K trimming potentiometer
for gain adjustment with the wiper tied to pin 12 (ground pin 12
for operation without adjustments). Use a 20K trimming potentiometer with the wiper tied to pin 11 for zer%ffset adjustment
(leave pin 11 open for operation without adjustment).
2. Bypass the analog and digital supplies and the + 1OV reference (pin 9) to ground with a 4.7I!F, 25V tantalum electrolytic
capacitor in parallel with a 0.1 I!F ceramic capacitor. Bypass
the +1OV reference (pin 9) to analog ground (pin 33).
3. Rated performance requires using good high-frequency circuit board layout techniques. the analog and digital grounds

are not connected internally. Avoid ground'related problems
by connecting the analog and digital grounds to one pOint, the
ground plane beneath the converter. Due to the inductance
and resistance of the power supply return paths, return the analog and digital ground separately to the power supplies.
4. Double-level multiplexing allows expanding the multiplexer
channel capacity of the HDAS-950 from 8 single-ended channels to 128 single-ended channels or the HDAS-951 from 4
differential channels to 32 single-ended channels.

TECHNICAL NOT.ES
1. The transfer accuracy of these multiplexers depends on
both the source resistance and the load resistance. With
zero source resistance, and assuming 2K ohms maximum
channel ON resistance, the load impedance should be at
least 20 megohms to achieve 0.01% accuracy. In practice,
it is recommended that a load impedance of at least 100

6-6

megohms be used to minimize errors. Source resistance
should be kept as low as possible so that accuracy is not affected; less than '1 K ohms is recommended. Higher source
resistance, in addition to affecting accuracy, will degrade the
settling time of the multiplexer.
2. Channel expansion uses the inhibit input of the multiplexer.
A logic 0 on this input disables the mulitplexer.

GENERAL DESCRIPTION
The MX-1616 and MX-818 are high-speed high performance analog multiplexers manufactured with a dielectrically isolated CMOS process. Both devices achieve transfer accuracies of 0.01% at channel sampling rates of up to
1.25 MHz over ±1 OV signal ranges. These multiplexers are
ideal for high-speed, multichannel, data acquisition systems where the multiplexer operates into a high impedance
load such as a sample-hold, buffer amplifier or instrumentation amplifier.

TECHNICAL NOTES
1. Bypass the ±15V and +5V power supplies with a 1 I1F, 25V
tantalum electrolytic capacitor in parallel with a 0.1 I1F ceramic capacitor.
2. Analog signals up to ±15V may be present while the MUX
power supplies are off.
3. The absence of an RON specification or output leakage
specification is related to the architecture of the switching network. The inputs see a constant 2.5 K Ohm input impedance
whether the channel is on or off.
4. Typical recovery times from an overvoltage condition of
>±3V is approximately 200 nanoseconds from a negative
overdrive and 700 nanoseconds from a positive overdrive.
5. Double level multiplexing may be used to provide up to
64 channels (nine MX-S26's required).

3. When power is off. current limit input signals on pins 4. 5,
6. and 7 to 20 mA. Failure to current limit will cause permanent damage to the device. as when powering up or
down. it is possible that two switches might be on at the
same time. Excessive current (greater than 20 mA) will
flow from the more positive input to the more negative input. permanently damaging the device. Applications
where the power supply for the multiplexer also powers the
signal sources may not require limiting resistors. See

TECHNICAL NOTES
1. The circuit design shows the connection of the AM-500 series
for fast settling operation with a closed loop gain of - 1. It can
be used for fast settling at closed loop gains up to -10. The
equivalent resistance seen by the summing junction should
be 500 ohms or less. For gains larger than - 1 use an input
resistor of 500 ohms and pick a feedback resistor for the required closed loop gain (1 k for - 2, 1.5k for - 3, etc.).
2. A small feedback capacitor should be used across the feedback resistor. Determine C in nanofarads from the following
formula:

C = 1 + IGI
0.816Rf
where G is closed loop gain and Rf is in kilohms.
3. Summing pOint leads must be kept as short as possible. Input
and feedback resistors should be soldered close to the body
of the resistor directly to the summing pOint (pin 4). Summing
point capacitance to ground must be kept very low.
4. Low output impedance power supplies should be used with 1
p.F tantalum bypassing capacitors at the amplifier supply terminals. There are internal 0.03 p.F ceramic capacitors in the
amplifier.
5. Although these amplifiers are inverting mode only, a dc voltage in the range of ± 5V may be applied to the positive input
terminal for offsetting the amplifier.
6. For interrupted power applications, apply power to the
AM-500 three (3) seconds before operating the device.

1. A 25 kG trimpet may be used for both input and output offset
adjusts. The trimpet is connected across the input offset adjust pins (Pins 1,15) and the wiper is connected to Pin 16.
For output offset adjust, the trimpet is connected across the
output offset adjust pins (Pins 10, 9) with the wiper connected
to Pin S.
2. For unity gain, RG is left open and the output gain select pin
(Pin 12) is tied to the output pin (Pin 11). To avoid oscillation
in the unity gain configuration, the connection between the
output gain select pin and the output pin should be kept as
short as possible.
3. Gain selection is accomplished in two stages. The input stage
gain (G 1) is selected by an external gain resistor (RG) connected across the (RG) pins, (Pins 2, 4) and is expressed as
follows:

ROJ-20 and ROJ-1 K are resistor tuneable oscillators whose
oscillation frequency is set with two external resistors. Output frequency range of ROJ-20 is 20Hz to 20KHz while that
of ROJ-1 K is 1KHz to 100KHz. Output distortion is as low
as 0.0018% typical at 1KHz frequency range. Output voltage temperature coefficiency is also as low as SOppm/oC.
Output voltage amplitude is internally trimmed at 2.SVrms
±O.S% and this amplitude is adjusted to the range from
SOOmV to 20Vp-p with external resistors. Sine and cosine
waves are generated from two output terminals. A synchronization input terminal is provided in order to fine tune
the relationship of these two outputs.

GENERAL DESCRIPTION

__

FLJ-ACR series are logic controlled resistor networks. They
are designed to be used with resistor tuneable filters such
as FLJ-UR series.

0.05(1.2)

Four separate resistor networks are included in one package. One network consists of four resistors such as R, R/2,
R/4 and Rl8. The value of R in FLJ-ACR1 is 1.59MQ while
that of FLJ-ACR2 is 150kQ.
FLJ-UR Series List

A combination of an FLJ-ACR and an FLJ-UR makes it possible to make a filter whose cutoff frequency or center frequency is set with BCD logic. It is also possible to use this
resistor network in the negative feedback loop of an amplifier circuit and control the gain with BCD logic.

TECHNICAL NOTES
1. FW-ACRl and FW-ARC2 contain four
separate resistor networks which are controlled by common logic inputs. There are
two types of FW-UR's (resistor tuneable
filters) which are to be connected with
FLJ-ACR's to build BCD Logic Programmable Filters. One type such as FWUR2LH or FW-URl BA requires two external resistors while all other FLJ-UR's require four external resistors to set a cutoff
frequency. Therefore, one FW-ACR can
control two FW-UR2LH's or FWURl BA's. See Figure 3.

GENERAL DESCRIPTION
FLJ-D1, 02, and DC are digitally programmable filters which
can set the cutoff frequency and center frequency with 3
digit BCD inputs.
Two-pole lowpass, bandpass, and highpass output functions are available simultaneously from three different outputs and notch function is available by combining these outputs to the uncommitted op amp.
To realize higher order filters, several filters can be cascaded. And to obtain higher performance of higher order filters,
both Gain and Q are designed to be set with external components.

The value of Rf is 3.183 MO.
The vaiueof Cext is calculated taking
these factors into consideration.
Each logic input is connected to
CMOS4000 series internally. Then each
input is pulled down with 100Kn resistors. The use of 10KO pull-up resistors to +5V is recommended when
filters are programmed with TTL logic.
An independent +5V zener diode is
contained in the filter. The output voltage range of this diode is +4.87V +5.12V. The connection shown in
Figure 3 is recommended if a filter is
driven by ±15V supplies only.
Analog GND (Pin3S) and logic GND
(Pin37) are separated. Connect
grounds of ±1SV and +SVexternally.
No return current of the digital power
supply should flow through the analog
ground.
The use of 4.7pF and 0.1pF bypass
capacitors for both ±1SV and +5V lines
close to the module is highly recommended.

FW-D5, and D6 series are lowpass filters
that, although compact, have higher order
and high attenuation performance. They
are Chebyshev type filters. The FW-D5LA
is a 5-pole filter which has a rolloff of 60
dB/oct and the FW-D6LA is a 6-pole filter
with a rolloff of 80 dB/oct. The cutoff frequency is programmed with 3-bit, TTLcompatible digital logic and the settings
can be changed to 8 different levels. Cutoff frequency range of the lower range
type (which has suffix 1) is 10Hz-2kHz,
and the higher range type (with suffix 2) is
.100Hz-20KHz.
Ripple within the pass band is minimal at
0.13dBp-p and the distortion rate is held
extremely low at 0.05%. These filters are
optimal as anti-aliasing filters in AID conversion circuits of data acquisition systems.

TECHNICAL NOTES
1. A switching-type power supply is not recommended. Install O.OII1F multilayer ceramic and 4.71!F
tantalum bypass capacitors In parallel as close to
the filter as possible.
2. Each logic input (Pins 21-24) which programs the
cutoff frequency has an internal analog comparator as shown in Fig. 6. External logic Signals are
TTL-compatible.
3. The fc setting input logic is negative true. Terminal open or +5V represents logic "0", while GND
level is logic "1". The INH terminal is used
normally open. OncelNH is given logic"I",ali4.2
and Tlogic inputs are inhibited and all internal
resistor network switches are opened. The fc
setting with external resistors becomes available
with logic "1" at this INH terminal. The relationship between Ic and the external resistors in this
case is as lollows:

4. An' l1-pole ultra-high attenuation filter is available once cascaded as shown in Fig. 7. As can be
seen Irom the curves (Figs. 4,5), the amplitude 01
the ripple in the pass band is reversed between
FLJ-05LA and FLJ-D6LA. As a result, when
connected in a cascade, the pass band ripple
amplitude is greatly reduced, and moreover, the
rolloff becomes steeper.
5, For filters that have been constructed like those in
this series, it is not recommended to change the Ic
setting range with external capacitors. This is
because trimming of the internal constants is
performed with pairs 01 internal resistors and
capacitors. Although shifting to a lower Ic setting
range is possible through the addition 01 external
capacitors, in this case a change will result in
ripple amplitude.

The FW-R series filters are of the highest order and have
the highest attenuation characteristics among the entire
group of DATEL filter products. Through the use of hybrid
techniques, even though compact in size, the FLJ-R series
filters have complete 8-pole lowpass and 3-pole pair bandpass filter functions. The cutoff (central) frequency can be
set with only 6 or 8 external resistors.

Bandpass ripple in the lowpass filter is 0.1 dB and boasts
outstanding performance with the distortion ratios for all
models being a mere 0.005%. Each model is composed of
the Suffix 1 and Suffix 2 types and varies according to cutoff
frequency setting range. The Suffix 1 model has a range
from 10Hz-2KHz and the Suffix 2 model has a range from
100Hz-20KHz. The FW-R series filters are optimum as antialiasing filters in AID conversion circuits of data acquisition
systems.

In this case, the external capacitors
should have high dielectric characteristics. It is recommended to use multilayerceramiccapacitors. Further, tolerance of these capacitors should be
within ±0.25%. For filters such as
these of higher order and with high
attenuation characteristics, the uniformity of the tolerance of external
resistors and capacitors has an effect
not only on the accuracy of the setting range, but also on the size of pass
band ripple.
2. Use series type power supplies for the
±15V power supplies because switching-type power supplies are not recommended. Install 4.7pF tantalum
and 0.01pF multilayer ceramic bypass
capacitors. It is recommended that
these be installed in parallel, and as
close to the filter as possible, between
the ±15V power supplies and ground.
3. Use metal film resistors with a tolerance better than 1% for the 6 or S fc
setting resistors.

3. Connect external resistors with short leads as close to the

FI...J..UR4LA1/2 Block Diagram· (Fig. 3)

TECHNICAL NOTES
1. Do not use a switching regulator. Use a well regulated
±15V power supply. Install 0.01 ~F bypass capacitors as
close to the filter as possible.

4. Use external capacitors with good stability and high dielectric resistance. It is recommended to use multilayer ceramic capacitors or plastic film capacitors.
5. Regulate output offset voltage. by using an external trimmer
(10 KG to 50 KG).
6. The FLJ-UR series filters are packaged single inline and
are compact in size. Installation at high-density may cause
temperature rises between elements. Installation with 0.8"
or more of space between filters can eliminate the problem.
7. Relation between fc and external resistor/capacitor:
With the FLJ-UR series. a cutoff or center frequency can be
set by 2 or 4 external resistors. The values of R of 2 or 4
external resistors for normal use can be calculated as;

In certain applications the resistance of each of 2 or 4 resistors may be changed. R, to R. shown in the block diagrams are the external resistors explained here. In standard use, the fc can be set to a minimum of 40 Hz. This is
because the values of R have to be increased to about
400K according to the relation between Rand fc. The fc
setting range can be expanded to lower band by adding 2
or 4 external capacitors.

In the applications in which the output offset, time drift, or

8. How to tune fc
As shown in the specifications, the fc setting accuracy is
3% depending on the accuracy of elements used. There is
no practical problem in tuning when they are used as lowpass or highpass filters. However, bandpass filters and
band elimination filters may require sharp tuning. Such filters can be tuned with external trimmers as shown in
Fig. 10. R" R2 and VR, are not used with the FLJUR1BA1/2.

TECHNICAL NOTES
1. The rated input voltage is ±lV. The maximum performance is obtained if input voltage does not exceed this
range.
2. Thesefiltersare 4pole Butterworth(2pole pair)filters. Cutoff
frequency is controlled by external voltage. The relationship
between control voltage and cutoff frequency is linear
(=proportional). Cutoff frequency ranges can be shifted
toward lower frequency region if four external capacitors
are added. See Figure 3.

FUNCTIONAL DESCRIPTION
The FlT-Cl is made up of two programmable filter sections
used in different combinations to meet various applications.
The switched capacitor stage (SCF), is a 7-pole, lowpass filter designed to provide an accurate, programmable passband
for fixed or dynamic applications.
The switching frequency may be derived either from a crystal
oscillator or from a system clock. Since the filter band edge
can be programmed by varying the frequency of the clock
which controls the filter's switches, it can track the sample rate
of an extemalAiD converter. Digital programming allows for
band edges of up to 20 KHz and gains of 1, 2, 4, or 8.
The RC filter stage is a low-order active filter with a bandedge accuracy of S%. This accuracy is adequate because the
filter sampling rate is SO times greater than the band edge frequency_

The band edge of the RC filter is programmable to insure sufficient rejection of any SC filter harmonics. Ratio matching of
on-chip resistors and capaCitors provides eight RC filter bandedges spanning a 12-to-l range.
. A decimator, placed at the output of the SC filter, samples the
differential output and converts it to a single-ended signal. In
addition, the decimator can be programmed to allow an Integer
decrease in the sampling rate by low filtering of the signal and
keeping every Nth sample, similar to a programmable samplehold. By choosing the proper decimation rate, the hold time at
SCOUT will be long enough to allow an AID conversion to take
place without the need of external S/H components. An external S/H is recommended for hold times faster than 100 j!S to
prevent more than 1/2 lSB of droop for a 12-bit AID converion.

GENERAL DESCRIPTION
The FLT -U2 is a universal active filter manufactured with a
thick-film hybrid technology. It uses the state- variable active
filter principle to implement a second order transfer function.
Three committed operational amplifiers are used for the
second order function while a fourth uncommitted operational amplifier can be used a a gain stage, summing amplifier,
buffer amplifier or to add another independent real pole.

MECHANICAL DIMENSIONS
INCHES (MM)

Two-pole low-pass, bandpass, and highpass output functions are available simultaneously from three different outputs, and notch and allpass functions are available by combining these outputs in the uncommitted operational
amplifier. To realize higher order filters, several FLT-U2's
can be cascaded. Q range is from 0.1 to 1,000 and resonant frequency range is 0.001 Hz to 200kHz. Frequency
stability is 0.01%/OC and resonant frequency accuracy is
within ±5% of calculated values. Frequency tuning is done
by two external resistors and Q tuning. by a third external resistor. For resonant frequencies below 50Hz, two external
tuning capacitors must be added. Exact tuning of the resonant frequency is done by varying one of the resistors
around its calculated value.

TECHNICAL NOTES
1. The FLT-U2 has simultaneous lowpass, bandpass, and
highpass output functions. The chosen output for a particular
function will be at unity gain based on Tables II and III. This
means that the other two unused outputs will be at other gain
levels. The gain of the lowpass output is always 10 dB higher
than the gain of the bandpass output and 20 dB higher than
the gain of the highpass output.
2. When tuning the filter and checking it over its frequency
range, the outputs should be checked with a scope to make
sure there is no waveform clipping present, as this will affect
the operation of the filter. In particular the lowpass output
should be checked since its gain is the highest.
3. Check f" the center frequency for bandpass and the cutoff
frequency for lowpass or highpass, at the bandpass output.
Here the peaking frequency can easily be determined for
high a filters and the 0° or 180 0 phase frequency can easily
be determined for Iowa filters (depending on'whether inverting or noninverting).
4. Tuning resistors should be 1% metal film reSistors with 100
ppm/oC temperature stability or better for best performance.
Likewise external tuning capacitors should be NPO ceramic
. or, other stable capacitor types.

8·30

A second order system is characterized by the location of its
poles in the s-plane as shown in Figure 2. The natural radian frequency of this system is Wo. In Hertz this is fo = Wo .
The resonant radian frequency of the circuit is different from the
natural radian frequency and is:
"" = Wo sin fIJ =

.JWo2 -

<7,2

The damping factor d determines the amount of peaking in the
filter frequency response and is defined as:

H(s) =

d=cosfIJ
The point at which the peaking becomes zero is called critical
damping and is d = ~J2.
a is found from d and is a measure of the sharpness of the
resonance of the peaking:

a =..!.
2d
Also, a =

fo
= ~
- 3 dB Bandwidth
2<7,

For high a filters the natural frequency and resonant frequency
are approximately equal.
"" '" Wo or f, '" fa
This is true since "" = Wo sin fIJ and sin fIJ = 1 as the poles move
close to the jw axis in the s-plane.
For high as (a > 1) we therefore have for the second order
filter:
fa '" Bandpass center frequency
'" Lowpass corner frequency
'" Highpass comer frequency
In the simplified tuning procedure which follows, the tuning is accomplished by independently setting the natural frequency and
a of the filter. This is done most simply by assuming unity gain
for the output of the desired filter function. Unity gain means a
gain of one (±) at dc for lowpass, at center frequency for bandpass, and at high frequency (f> >fo) for highpass. Unity gain
does not apply to all outputs simultaneously but only to the
chosen output based on the component values given in the
tables. Figure 3 shows the relative gains of the three simultaneous outputs assuming the bandpass gain is set to unity.
Note that lowpass gain is always 10, dB higher than bandpass
'gain and highpass gain is·always 10 dB lower than bandpass
gain.

SIMPLIFIED TUNING PROCEDURE
1. Select the desired transfer function (lowpass, bandpass, or
highpass) and inverted or non inverted output. From this
determine the filler configuration (inverting or noninverting)
using Table I.
TABLE I

FILTER CONFIGURATION

7. This procedure is based on unity gain output for the desired
function. For additional gain, the fourth uncommitted operational amplifier should be used as an inverting or noninverting
gain stage following the selected output. See Figure 4. A
third pole on the real axis of the s-plane may also be added to
the transfer function by adding a capacitor to the gain stage
as shown in Figure 5.

2. Starting with the desired natural frequency and 0 (determined from the filler transfer function or s-plane diagram), compute foO. For foO> 1O· the actual realized 0 will exceed the
·calculated value. At foO = 10· the increase is about 1% and
at foO = lOs it is about 20%.

5. Using the value of fa from Step 2, set the natural frequency of
the filler by finding R. and Rs from the equation:

-jw

R. = Rs = 5.03 X 107

Figure 2.
S-Plane Diagram

fa
where R. and Rs are in ohms and fo is in Hertz. The natural
frequency varies as y'R.Rs and therefore one value may be
increased and the other decreased and the natural frequency will be constant if the geometric mean is constant. To
maintain constant bandwidth at the bandpass output while
varying center frequency, fix R. and vary Rs.
6. For fo<50 Hz the internal 1000 pF capacitors should be
shunted with external capacitors across pins 5 & 7 and 13 &
14. If equal value capacitors are used, R. and Rs are then
computed from:

R. = Rs = 5.03 X 1010 (C in pF)
foC
For unequal value capacitors this becomes:
X 10 10

R. = Rs = 5.03
(C 1C2 in pF)
f oy'C 1C2
In both cases the capacitance is the sum of the external
values and the internal 1000 pF values.

ADVANCED FILTERS
All of the common !liter types can be realized by using cas- ..
caded FLT-U2 stages. This includes multi-pole Butterworth,
Bessel, Chebyshev, and Elliptic types. The basic procedure
is to implement each pole pair with a single FLT-U2 and cascade enough units to realize all poles. A real axis pole is implemented by an uncommitted operational amplifier stage.
Each stage should be separately tuned with an oseillator and
scope and then the stages connected together and checked.
See Figure 6.

Figure 7.
Realization of Notch Filter

A notch filter can be constructed in several ways. The first
way is to use the FLT-U2 as an inverting bandpass !liter and
sum the output of the filter with the input signal by means of
the uncommitted operational amplifier. This produces a net
subtraction at the center frequency of the bandpass which
produces a null at the output of the amplifier. (see Figure 7).
Likewise lowpass and highpass outputs (which are always in
phase) can be subtracted from each other with an external
operational amplifier. The highpass output must have some
gain added to it, however, so that its gain is equal to that of
the lowpass output. A third method is to use two separate
FLT-U2's, one as a two-pole lowpass filter and the other as a
two-pole high pass filter. Again the outputs are subtracted in
an operational amplifier. This method permits independent
tuning of the two sections to get the best null response.

PROCESS MONITORS/CONTROLLERS

DATEL designs and manufactures a complete line of
Process Monitors/Controllers supporting Thermocouples,
RTDs, Strain Gages, and Voltage/Current signal inputs.
These low cost units contain such features as built-in RS232 serial port (RS-422/485 optional), user-selectable
setpoint outputs (up to 4 discrete and 1 optional Analog),
built-in configuration and setup command set, fully
isolated inputs (to 1500 Volts, typ.) and a six-character,
14-segment vacuum fluorescent display (blue-green).
Each model may be configured and operated from either
the front panel or via the serial port. For reliability,
accuracy, and low price, DATEL's PM-5000 series
Process Monitors/Controllers are simply the best.

DATEL is committed to meeting the demading requirements of military, aerospace, and severe
environment applications. Toward that end, DATEL offers several options in its quality program.
OPTION 1 -

MIL-STD-883 Class H Compliant Devices

DATEL Inc. is QUALIFIED by the Defense Electronics Supply Center for the manufacture of selected hybrid microcircuits in FULL COMPLIANCE with Military Specification MIL-H-38534 (Hybrid Microcircuits), FSC 5962, and MIL-STD-1772 SECTION B.
The accompanying chart gives a concise overview of MIL-STD-883 screening requirements and
their implications for DATEL customers.

TEST

A-I

METHOD

PURPOSE

(Precap)

Method 2017

Eliminates devices with potential for failure under mechanical, electrical, or thermal stress.

Stabilization
Bake

MethQd 1008,
Test Condition C, 24 hrs. at 150°C

Eliminates device failure due to storage at elevated temperatures.

Temperature
Cycling

Method 1010,
Test Condition C, -65 to 150°C

Determines resistance of device to sudden exposure to extreme temperature changes. Removes potential failures due to thermal stress
on bonds, etc.

Constant
Acceleration

Method 2001,
Test Condition A, Y AXIS, 5 kg.

Eliminates potential failures due to structural or
mechanical weakness not detected in shock or
vibration test.

Burn-in Test

Method 1015,
Test Condition B, 160 hrs. at +125 °C

Stresses devices at temperature in order to
eliminate infant mortality failures.

PDA10%

Static Tests performed at +25 °C

Percent defective allowable - Rejects lots with
static test failures greater than 10%.

Final Electrical
Test

Performed at +25 °C and at max. and
min. operating temperatures

Verifies that device still meets specified data
sheet parameters.

Seal Fine
and Gross

Method 1014,
Test Condition A (fine), 1 x 10·7 ccl
Sec. for volume of ~0.5 to <1.0 cm3
and 5 x 10-8 cclSec. for volume of
~1.0 to <10.0 cm3. Test Condition C
(gross)

Insures hermeticity of device package. Eliminates degradation due to absorption of water
vapor or other contaminants.

External Visual

Method 2009

Insures that materials, design, construction,
marking, and workmanship conform with applicable procurement documentation.

DATEL, Inc. 11 Cabot BoUlevard, Mansfield, MA 02048-1194ITEL (508) 339-3000ITLX 174388/FAX (508) 339-6356

MIL-STD-883 compliancy also requires that complete documentation be available to support the
product. An analysis of the design along with element and package evaluations are performed
to ensure a high quality product. The manufacturing process is also stringently controlled in order to obtain the high quality level.
Initial qualification requires passing the MIL-STD-883 test for groups A, B, C, and D. After initial
qualification, groups A & B are tested for all lots. Group C is tested initially and to qualify any
product changes which may occur. Group 0 testing is also performed initially and at intervals
not exceeding 6 months for future lots.
