Overview
KA2206B 2.
3W DUAL AUDIO POWER AMP 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.
12-DIPH-300 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.
