Thanks to the DMOS output stage the TDA7565 has a very low distortion allowing a clear powerful sound. The built-in voltage converter control block assures a very high output power with an extremely low number of added components.The dissipated power under average listening condition is alligned to the conventional solutions (4x40W). s s s s s BLOCK DIAGRAM VS MUTE CLK DATA VCC1 VCC2 CC GND I2C BUS MUTE1 MUTE2 CLIP DETECTOR VOLTAGE CONVERTER CONTROL MG VOLTAGE CONVERTER EXTERNAL CIRCUIT IN RF F OUT RF+ 12/26dB OUT RFR SHORT CIRCUIT PROTECTION OUT RR+ 12/26dB OUT...
