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:P
o
=2.3W(Typ) at V
cc
=9V,R
L
=4惟.
Bridge: P
o
=4.7W(Typ) at V
cc
=9V,R
L
=8惟
.
*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.
