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

Pin 14 Current Comments
Minimum pin 14 current required for shutdown is 0 5 mA and must not exceed 1 mA
Maximum pin 14 current for amplifier not shut down is 0 05 mA
The typical shutdown switch point current is 0 2 mA
Note 1 For operation in ambient temperatures above 25 C the device must be derated based on a 150 C maximum junction temperature and a thermal resistance
of 90 C W junction to ambient
