General description
The TDA8920 is a high efficiency class-D audio power amplifier. Typical output power is 2 x 80 W and it operates with
high efficiency and very low dissipation. 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 up to =+30 V and consumes a very low quiescent current.

Features

- Usable as a stereo Single-Ended (SE) amplifier or
as a mono amplifier in Bridge-Tied Load (BTL)
- Fixed gain of 30 dB in Single Ended (SE) and 36 dB in Bridge-Tied-Load (BTL)
- High output power
- Good ripple rejection
- Internal switching frequency can be overruled by an external clock
- No switch-on or switch-off plop noise
- Short-circuit proof across the load
- Electrostatic discharge protection
- Thermally protected

Applications
- Television sets
- Home-sound sets
- Multimedia systems
- All mains fed audio systems
