8920BJ TDA8920B

The TDA8920B is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 × 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 c.
