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.
