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. 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.

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 general-
purpose video and pulse amplifiers.

The device achieves low equivalent noise voltage
through special processing and a new circuit
layout incorporating input transistors with low
base resistance.
The TL592B is characterized for operation from
0°C to 70°C.
