YOUDA INTEGRATED CIRCUIT 2.4W STEREO AUDIO POWER AMP¡ª¡ 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 45d B(Bridge: 51d B) but availability with external resistor added - Minimum number of external parts required BLOCK DIAGRAM 16 Vcc + 15 14 13 GND 12 11 10 9 Pre-GND 5k + GND Wu Xi You Da Electronics Co., Ltd Add: No.5 Xijin Road, National Hi-Tech Industrial Development Zone, Wuxi Jiangsu China Tel: 86-510-5205117 86-510-5205108 Fax: 86-510-5205110 Website: .e-youda.
