LH0041LH0041C 02 Amp Power Operational Amplifier

General Description

The LH0021LH0021C and LH0041LH0041C are general

purpose operational amplifiers capable of delivering large

output currents not usually associated with conventional IC

Op Amps The LH0021 will provide output currents in ex-

delivers currents of 200 mA at voltage levels closely ap-

proaching the available power supplies In addition both the

inputs and outputs are protected against overload the de-

vices are compensated with a single external capacitor and

are free of any unusual oscillation or latch-up problems

The excellent input characteristics and high output capabili-

ty of the LH0021 make it an ideal choice for power applica-

tions such as DC servos capstan drivers deflection yoke

drivers and programmable power supplies

The LH0041 is particularly suited for applications such as

torque driver for inertial guidance systems diddle yoke driv-

er for alpha-numeric CRT displays cable drivers and pro-

grammable power supplies for automatic test equipment

The LH0021 is supplied in a 8 pin TO-3 package rated at 20

watts with suitable heatsink The LH0041 is supplied in both

12 pin TO-8 (25 watts with clip on heatsink) and a power 8

pin ceramic DIP (2 watts with suitable heatsink)

The

LH0021 and LH0041 are guaranteed over the temperature
