µA733/733C
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.
