UTC 2206 LINEAR INTEGRATED CIRCUIT 2.5W DUAL AUDIO POWER AMP DESCRIPTION The 2206 is a monolithic integrated circuit consisting of a 2-channel power amplifier .It is suitable for stereo and bridge amplifier application of radio cassette tape recorders. FEATURES *High output power Stero: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. *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.
