LOW VOLTAGE AUDIO POWER AMP
S1A0386A01
1
INTRODUCTION
The S1A0386A01 is a power amplifier designed for use in low
voltage consumer applications. The gain is internally set to 20
to keep the external part count low, but the addition of an exter-
nal resistor and Capacitor between Pin 1 and 8 will increase the
gain to any value up to 200.
