UA733CN (TEXAS INSTRUMENTS)

The UA733CN 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 common-mode and supply-voltage rejection ratios. Fixed differential amplification of 10, 100 or 400V/V may be selected without external components or amplification may be adjusted from 10 to 400V/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 wide bandwidth, low phase shift and excellent gain stability are required.
