NSC LM733CN Lm733/lm733c differential amplifier Datasheet

LM733/LM733C Differential Amplifier
General Description
Features
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 b55§ C to
a 125§ C military temperature range. The LM733C is specified for operation over the 0§ C to a 70§ C temperature range.

Note 1: The maximum junction temperature of the LM733 is 150§ C, while that of the LM733C is 100§ C. For operation at elevated temperatures devices in the TO100 package must be derated based on a thermal resistance of 150§ C/W junction to ambient or 45§ C/W junction to case. Thermal resistance of the dual-in-line
package is 90§ C/W.
Note 2: Pins G1A and G1B connected together.
Note 3: Pins G2A and G2B connected together.
Note 4: Gain select pins open.
Note 5: Refer to RETS733X drawing for specifications of LM733H version.
