LM733/LM733C Differential Amplifier General Description Features
The LM733/LM733C is two-stage, differential input, differ- MHz bandwidth
ential output, wide-band video amplifier. The use of internal k X input resistance series-shunt feedback gives wide bandwidth with low phase Selectable gains of 10, 100, distortion and high gain stability. Emitter-follower outputs No frequency compensation provide high current drive, low impedance capability. Its
High common mode rejection ratio at high frequencies
MHz bandwidth and selectable gains of 10, and 400, without need for frequency compensation, make it

Frequently Asked Questions
What is the key difference between the LM733 and LM733C?
The LM733 is designed for a military temperature range (55°C to 125°C), while the LM733C operates in a commercial range (0°C to 70°C).
What kinds of applications are suitable for this amplifier?
It is recommended for memory element drivers, pulse amplifiers, and wide band linear gain stages like magnetic tape systems erasers.
What is the maximum operating bandwidth?
The device features a specified wide bandwidth up to 120 MHz.
Does the TO-100 package require special setup considerations?
Yes, for operation at elevated temperatures, devices in the TO-100 package must be derated based on thermal resistance.
