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

• High output power

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

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

• Low switching distortion at high frequency.

• Small 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 45dB (Bridge : 51dB) but availability with external resistor added.

• Minimum number of external parts required.

• Easy to design radiator fin.
