UA733M DIFFERENTIAL VIDEO AMPLIFIERS

ordering information The µA733 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 co.

Features

h common-mode 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 general-purpose video and pulse amplifiers where .
