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 exter­nal resistor and Capacitor between Pin 1 and 8 will increase the
gain to any value up to 200.

FEATURES

• Battery operation

• Minimum external parts

• Wide supply voltage range:
4V − 12V (S1A0386A01-D0B0)
4V − 9V (S1A0386A01-S0B0)

• Low quiescent current drain (4mA)

• Voltage gains: 20 − 200dB

• Ground referenced Input

• Self-centering output quiescent voltage

• Low distortion
