YOUDA INTEGRATED CIRCUIT
YD2025A
2.4W STEREO AUDIO POWER AMP YD2025A
DESCRIPTION
The YD2025A 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=2.4W(Typ) at Vcc=9V, RL=4
Bridge: Po=4.7W(Typ) at Vcc=9V, RL=8
*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
