YD2025A

YOUDA INTEGRATED CIRCUIT YD2025A 2.4W STEREO AUDIO POWER AMP¡ª¡ DESCRIPTION YD2025A 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 BLOCK DIAGRAM 16 Vcc + 15 14 13 GND 12 11 10 9 Pre-GND 5k 50 + GND 1 2 3 4 5 6 7 WuXi YouDa 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: www.e-youda.com SHENZHEN OFFICE Tel£º 86-755-83740369 13823533350 Fax£º 86-755-83741418 Ver 3.1 1 of 4 2004-9-20 RIPPLE FILTER 8 YOUDAINTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER Vi=0 Supply Voltage Vi>0 Output Peak Current Power Dissipation Operating Temperature Storage Temperature (Tamb=25¡æ ) VALUE 20 16 2.5 4 -25¡« +70 -55¡« +150 YD2025A SYMBOL VCC IO(P) PD Topr Tstg UNIT V A W ¡æ ¡æ ELECTRICAL CHARACTERISTICS (Tamb=25¡æ , Vcc=9V, f=1kHz, Rg=600¦¸ PARAMETER SYMBOL , Unless other...
