General description
The TDA8922B is a high efficiency class-D audio power amplifier with very low
dissipation. The typical output power is 2
×
50 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 and consumes a very low quiescent current.
