TDA8920/TDA8920B pdf datasheet

1. General descripTIon

The TDA8920B is a high efficiency class-D audio power amplifier with very low

dissipaTIon. The typical output power is 2 &TImes; 100 W.

The device is available in the HSOP24 power package and in the DBS23P through-hole

power package. The 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.
