LM733/LM733C Differential Amplifier
LM733/LM733C Differential Amplifier
August 1989
General Description
The LM733/LM733C is a two-stage, differential input, differential output, wide-band video amplifier. The use of internal
series-shunt feedback gives wide bandwidth with low phase
distortion and high gain stability. Emitter-follower outputs
provide a high current drive, low impedance capability. Its
120 MHz bandwidth and selectable gains of 10, 100 and
400, without need for frequency compensation, make it a
very useful circuit for memory element drivers, pulse amplifiers, and wide band linear gain stages.
The LM733 is specified for operation over the
a
125§C military temperature range. The LM733C is speci-
fied for operation over the 0
Ctoa70§C temperature range.
