LINEAR INTEGRATED CIRCUIT
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: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.
