4.6W AUDIO POWER AMP S1A2206D01
INTRODUCTION
The S1A2206D01 is a monolithic integrated circuit consisting of a 2channel power amplifier. It is suitable for the stereo and bridge amplifier application of a radio cassette tape recorder.
12-DIPH-300
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
