INTRODUCTION

The S1A2206D01 is a monolithic integrated circuit consisting of a 2-channel power amplifier. It is suitable for the stereo and bridge ampli fier application of a radio cassette tape recorder.

FEATURES

• High power output

Stereo : PO = 2.3 W (Typ) at VCC = 9 V, RL = 4

Bridge : PO = 4.7 W (Typ) at VCC = 9 V, RL = 8

• Low switching distortion at high frequency

• Reduced shock noise at the time of power on/off due to a built-in muting circuit

• Good ripple rejection due to a built-in ripple filter

• Good channel separation

• Soft tone at the time of output saturation

• Closed loop voltage gain fixed at 45dB (Bridge : 51 dB) but availability with external resistor added

• Minimum number of external parts required

• Easy-to-design radiator fin
