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.

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.

Soft tone at the time of output saturation.

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.
