LM391 Audio Power Driver

General Description

The LM391 audio power driver is designed to drive external

power transistors in 10 to 100 watt power amplifier designs.

High power supply voltage operation and true high fidelity

performance distinguish this IC. The LM391 is internally pro-

tected for output faults and thermal overloads; circuitry pro-

viding output transistor protection is user programmable.
