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. 16-DIP-300A ORDERING INFORMATION
