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. 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.
