2206 LINEAR INTEGRATED CIRCUIT
www.unisonic.com.tw 1 of 6 Copyright © 2014 Unisonic Technologies Co., LTD QW-R107-018.B 2.5W DUAL AUDIO POWER AMP DESCRIPTION The UTC 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 Stereo:P O=2.3W(Typ) at VCC=9V,RL=4Ω. Bridge: P O=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. ORDERING INFORMATION Order Number Package Packing 2206G-D12H-T DIP-12H Tube MARKING
