KA2206B 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.
KA2206B Key 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
