GENERAL DESCRIPTION
The TDA8920 is a high efficiency class-D audio power
amplifier with very low dissipation. The typical output
power is 2
× 80 W. The device comes in a HSOP24 power
package with a small internal heatsink. Depending on
supply voltage and load conditions a very small or even no
external heatsink is required. The amplifier operates over
a wide supply voltage range from
±12.5 to ±30 V and
consumes a very low quiescent current.
