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
