SAMSUNG S1A2206D01

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
16-DIP-300A
•
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
