TDA8920B

2 × 100 W class-D power ampliﬁer

Rev. 02 — 07 November 2005

Product data sheet

1. 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 (±32 V non operating) and consumes a very low quiescent current.

2. 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

3. Applications

■ Television sets

■ Home-sound sets

■ Multimedia systems

■ All mains fed audio systems

■ Car audio (boosters)
