LH0021/LH0021C 1.0 Amp Power Operational Amplifier
LH0041/LH0041C 0.2 Amp Power Operational Amplifier
General Description
The LH0021/LH0021C and LH0041/LH0041C 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-
12 pin TO-8 (2.5 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

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.
