UTC LM386
LINEAR INTEGRATED CIRCUIT
LOW VOLTAGE AUDIO POWER
AMPLIFIER
DESCRIPTION
The UTC LM386 is a power amplifier, designed for
use in low voltage consumer applications. The gain is
internally set to 20 keep the external part count low,
but the additional of external resistor and capacitor
between pin 1 and pin 8 will increase the gain to any
value up to 200.
