CD2025B Datasheet | Shaoxing Silicore Technology

Silicore 2.3W DUAL AUDION POWER AMP DESCRIPTION The CD2025B is a monolithic integrated circuit consisting of a 2-channel po wer amplifier. It is suitable for stereo and bridge amplifier application of radio cassette tape recorder. Outline Drawing Features z High ou tput power Stereo: Po=2.3W (Typ) at Vcc=9V, R L =4 Ω Bridge: Po=4.7W (Typ) at Vcc=9V, R L =8 Ω z z z z z z Low switching distortion at high frequency. Small shock noise at th e time of power on/off due to a built-in mu ting circuit Good ripple rejection due to a built-in ripple filter. Good ch annel separation. Soft tone at the time of output saturation. Closed loop voltage gain fixed 45 d B (Bridge: 51dB) but availability with external resistor added. z z Minimu m nu mb er of external parts required. Easy to design radiator fin.
