200-MHz Bandwidth
250-kΩ Input Resistance
Selectable Nominal Amplification of 10,

No Frequency Compensation Required
Designed to be Interchangeable With
Fairchild uA733C and uA733M

description
The uA733 is a monolithic two-stage video
amplifier with differential inputs and differential
outputs.
Internal series-shunt feedback provides wide
bandwidth, low phase distortion, and excellent
gain stability. Emitter-follower outputs enable the
device to drive capacitive loads, and all stages are
current-source biased to obtain high commonmode and supply-voltage rejection ratios.
Fixed differential amplification of 10 V/ V, 100 V/ V,
or 400 V/ V may be selected without external
components, or amplification may be adjusted
from 10 V/ V to 400 V/ V by the use of a
single external resistor connected between 1A
and 1B. No external frequency-compensating
components are required for any gain option.

The device is particularly useful in magnetic-tape
or disc-file systems using phase or NRZ encoding
and in high-speed thin-film or plated-wire
memories. Other applications include generalpurpose video and pulse amplifiers where wide
bandwidth, low phase shift, and excellent gain
stability are required.

The uA733C is characterized for operation from 0°C to 70°C; the uA733M is characterized for operation over
the full military temperature range of – 55°C to 125°C.
