TDA8920BTH 200 watt amp D class amplifier electronic project

A very simple 200 watt amp d class amplifier electronic project can be designed using the TDA8920BTH audio power amplifier IC . This TDA8920BTH 200 watt amp d class amplifier power amplifier audio IC has a very high efficiency with very low dissipation, providing a very high output power ( typical output power is 2 x 100 W) .
The device is available in the HSOP24 power package and in the DBS23P through-hole power package. The TDA8920BTH 200 watt amp 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.
If the supply voltage drops below ±12.5 V, the UnderVoltage Protection (UVP) circuit is
activated and the system will shut-down correctly.

The audio input signal of this power 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.
The amplifier system can be switched to one of three operating modes by pin MODE:
-Standby mode; with a very low supply current
-Mute mode; the amplifiers are operational; but the audio signal at the output is suppressed by disabling the VI-converter input stages
-Operating mode; the amplifiers are fully operational with output signal

The following protections are included in this high power amplifier :
OverTemperature Protection (OTP),OverCurrent Protection (OCP),Window Protection (WP), Supply voltage protections (UnderVoltage Protection (UVP), OverVoltage Protection (OVP), UnBalance Protection (UBP)).
In some applications may be necessary to connect an external heatsink to the IC (limiting factor is the 150 °C maximum junction temperature).
