General description
The TDA8920B is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 x 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.
Features
- Zero dead time switching
- Advanced current protection: output current limiting
- Smooth start-up: no pop noise due to DC offset
- High efficiency
- Operating supply voltage from +-12.5 V to +-30 V
- Low quiescent current
- 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
- High supply voltage ripple rejection
- Internal switching frequency can be overruled by an external clock
- Full short-circuit proof across load and to supply lines
- Thermally protected
