description
This device 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. All stages are current-source biased to obtain high common- mode and supply-voltage rejection ratios. Fixed differential amplification of nominally 400 V/V can be selected without external components, or amplification may be adjusted from 0 to approximately 400 V/V by the use of a single external resistor connected between the gain adjustment pins A and B. No external frequency-compensating components are required for any gain option. The device is particularly useful in magnetic-tape or disk-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. The TL592 is characterized for operation from 0°C to 70°C. Copyright 1991, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.
