| YOUDA INTEGRATED CIRCUIT YD2206 2.5W DUAL AUDIO POWER AMP----YD2206 DESCRIPTION The YD2206 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=2.5W(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 12 Vcc + 11 10 TAB 9 8 7 Pre-GND 5k 50 + - 1 2 3 TAB 4 5 WuXi YouDa Electronics Co., Ltd Add: No.5 Xijin Road, National Hi-Tech Industrial Development Zone, Wuxi Jiangsu China Tel: 86-510-85205117 86-510-85205106 Fax: 86-510-85205110 Website: www.e-youda.com SHENZHEN OFFICE Tel 86-755-83740369 Fax 86-755-83741418 Ver 5.0 1 of 4 2006-06-28 RIPPLE FILTER 6 YOUDA INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Vi=0 Vi>0 (Tamb=25) SYMBOL Vcc Iop PCB PD 1 PD2 Topr Tstg VALUE 20 15 2.0 4.0 1.7 -25+70 -55+150 YD2206 UNIT V A W W Output Peak Current Power Dissipation 80*60*1.2mm3 No Heat Sink Operating Temperature t Storage Temperature ELECTRICAL CHARACTERISTICS (Tamb=25, Vcc=9V, f=1kHz, Rg=600, Unless otherwise specified) PARAMETER SYMBOL 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 Vi>0 Vi=0 THD=10%, RL=4 THD=10%, RL=3 6 9 26 15 40 V mA W/CH 2.0 2.5 3.0 0.2 1.0 47 dB 53 k 1.0 mV dB dB % THD Gv PO=0.4W/CH Stereo Bridge 43 49 45 51 30 0.3 46 Zi VNO RR CT f=1kHz Rg=10k, BPF=22Hz22kHz F=100Hz, Rg=600 VO=0dBm 46 55 WuXi YouDa Electronics Co., Ltd 2 of 4 Website: www.e-youda.com YOUDA INTEGRATED CIRCUIT APPLICATION CIRCUIT (1) YD2206 TYPE APPLICATION + 100 6 IN 1 + 12 10 YD2206 + 470 0.1 + 100 + 470 0.15 3 Vcc 8 + 11 2.2 9 100 IN 2 + + _ RL + 5 + 2 100 + 470 RL 2.2 4 100 + 7 TAB _ 1 0.15 (2) YD2206 BTL APPLICATION Vcc + 100 IN 6 12 10 8 + 470 + 100 11 + 2.2 + 100 + _ 9 0.15 3 6 + + 2 100 RL + 100 4 1 7 _ 0.15 TAB WuXi YouDa Electronics Co., Ltd 3 of 4 Website: www.e-youda.com YOUDA INTEGRATED CIRCUIT OUTLINE DRAWING YD2206 WuXi YouDa Electronics Co., Ltd 4 of 4 Website: www.e-youda.com |
