April 15, 1992 853-1064 06456

DESCRIPTION

The 733 is a monolithic differential input, differential output,

wide-band video amplifier. It offers fixed gains of 10, 100, or 400

without external components, and adjustable gains from 10 to 400

by the use of an external resistor. No external frequency

compensation components are required for any gain option. Gain

stability, wide bandwidth, and low phase distortion are obtained

through use of the classic series-shunt feedback from the

emitter-follower outputs to the inputs of the second stage. The

emitter-follower outputs provide low output impedance, and enable

the device to drive capacitive loads. The 733 is intended for use as

a high-performance video and pulse amplifier in communications,

magnetic memories, display and video recorder systems.

FEATURES

•120MHz bandwidth

•250kΩinput resistance

•Selectable gains of 10, 100, and 400

•No frequency compensation required

•MIL-STD-883A, B, C available
