TL592B DIFFERENTIAL VIDEO AMPLIFIER SLFS001A – JUNE 1985 – REVISED APRIL 1988 D D D Adjustable Gain to 400 Typ No Frequency Compensation Required Low Noise . . . 3 µV Typ Vn description This device is a monolithic two-stage video amplifier with differential inputs and differential outputs. It features internal series-shunt feedback that provides wide bandwidth, low phase distortion, and excellent gain stability. Emitterfollower outputs enable the device to drive capacitive loads. All stages are current-source biased to obtain high common-mode and supplyvoltage rejection ratios. The differential gain is typically 400 when the gain adjust pins are connected together, or amplification may be adjusted for near 0 to 400 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 generalpurpose video and pulse amplifiers.
