TDA8920BTH
2 X 100 W class-D power amplifier

General description

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 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

Applications

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

■ Car audio (boosters).
