m o .c CIRCUIT YOUDA INTEGRATED YD8207 U 4 t e e h AUDIO POWER AMPLIFIER-YD8207 DUAL S a t a D . DESCRIPTION w w YD8207 is an audio power IC with built-in two channels developed for portable radio cassette tape recorder. wBecause of the parts reduction and SIP(Single In line Package), space merit is remarkable. Thermal shut down protection circuit is built in. FEATURES *High Power: Po(1)=2.5W/CH(Typ.) (Vcc=9V, RL=4Ω, f=1kHz, THD=10%) Po(2)=4.6W/CH(Typ.) (Vcc=12V, RL=4Ω, f=1kHz, THD=10%) *Low popping noise at power ON. *Small quiescent current: Iccq=19mA(Typ.) (Vcc=9V, Vin=0) *Soft clip *Built-in thermal shut down protection circuit *Operation supply voltage range: Vcc=6V¡« 15V *Best for supply voltage: 9V or 12V BLOCK DIAGRAM m o .c U 4 t e e h WuXi YouDa Electronics Co., Ltd S a tJiangsu China Add: No.5 Xijin Road, National Hi-Tech Industrial Development Zone, Wuxi a Tel: 86-510-5205117 86-510-5205108 Fax: 86-510-5205110 Website: www.e-youda.com D .
