TDA8920BTH 200 watts d class amplifier circuit diagram


Posted on Feb 5, 2014

This high power class D audio amplifier electronic project is designed using the TDA8920BTH audio power amplifier IC. This power amplifier audio IC has a very high efficiency with very low dissipation, providing a very high output power. The typical output power is 200 watts ( 2 x 100 W). The TDA8920BTH 200 watts d class amplifier operates over

a wide supply voltage range from ±12. 5 V to ±30 V ( ±32 V non operating) and consumes a very low quiescent current. The audio input signal of this 200 watts d class amplifier is converted into a digital pulse width modulated signal via an analog input stage and Pulse Width Modulation (PWM) modulator. To enable the output power transistors to be driven, this digital PWM signal is applied to a control and handshake block and driver circuits for both the high side and low side.
