Product Information

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 otherwise specified) TEST CONDITIONS MIN TYP MAX UNIT Operating Supply Voltage Quiescent Circuit Current Output Power Total Harmonic Distortion Closed Loop Voltage Gain Input Resistance Output Noise Voltage Ripple Rejection Ratio Cross-Talk Vcc ICCQ PO THD Gv Vi>0 Vi=0 THD=10%, RL=4¦¸ THD=10%, RL=3¦¸ PO=0.4W/CH Stereo Bridge 43 49 2.0 9 26 2.4 15 40 V mA W/CH 3.0 0.2 45 51 30 0.3 46 46 55 1.0 1.0 47 dB 53 k¦¸ mV dB dB % Zi VNO RR CT f=1kHz Rg=10k¦¸ , BPF=22Hz¡« 22kHz F=100Hz, Rg=600¦¸ VO=0dBm WuXi YouDa Electronics Co., Ltd 2 of 4 Website: www.e-youda.com YOUDA INTEGRATED CIRCUIT APPLICATION CIRCUIT £¨ 1£© YD2025A TYPE APPLICATION + 100¦Ì + 8 16 14 YD2025A Vcc 0.1¦Ì 470¦Ì + 100¦Ì + 470¦Ì 0.15¦Ì 3 IN 1 2.2¦Ì + 10 + 15 RL 11 100¦Ì IN 2 2.2¦Ì 6 100¦Ì + 4 + + _ + 7 + 2 100¦Ì + 470¦Ì RL _ 1 0.15¦Ì 5 9 12 13 (2) YD2025A BTL APPLICATION Vcc + 100¦Ì IN 2.2¦Ì + 100¦Ì 7 11 8 16 14 10 + 470¦Ì + 100¦Ì 15 + + _ 0.15¦Ì 3 + + 2 100¦Ì RL + 100¦Ì 6 1 4 _ 0.15¦Ì 5 9 12 13 WuXi YouDa Electronics Co., Ltd 3 of 4 Website: www.e-youda.com YOUDA INTEGRATED CIRCUIT OUTLINE DRAWING YD2025A WuXi YouDa Electronics Co., Ltd 4 of 4 Website: www.e-youda.com ...
