KA2206B
The KA2206B is a monolithic intergrated circuit consisting of a
2-channel power amplifier. It is suitable for stereo and bridge
amplifier application of radio cassette tape recorder.
FEATURES
BLOCK DIAGRAM
Stereo : P
Bridge : P
built-in muting circuit
with external resistor added.
High output power
Low switching distortion at high frequency.
Small shock noise at the time of power on/off due to a
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 45dB (Bridge : 51dB) but availability
Minimum number of external parts required.
Easy to design radiator fin.
