2.3W DUAL AUDION POWER AMP CD2025B
DESCRIPTION
The CD2025B 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 recorder.
Outline Drawing
F E AT U R E S
z High output power
St ereo: Po=2 .3W (Typ) at Vcc=9V, RL=4
Bridge: Po=4.7W (Typ) at Vcc=9V, R L=8
z Low switching distortion at high frequency.
z Small shock noise at the time of power on/off due to a built-in muting circuit
z Good ripple rejection due to a built-in ripple filter.
z Good channel separation.
z Soft tone at the time of output saturation.
z Closed loop voltage gain fixed 45dB (Bridge: 51dB) but availability with external
resistor added.
z Minimum number of external parts required.
z Easy to design radiator fin.
