8920BJ
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
s Zero dead time switching
s Advanced current protection: output current limiting
s Smooth start-up: no pop noise due to DC offset
s High efficiency
s Operating supply voltage from ±12.5 V to ±30 V
s Low quiescent current
s Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied
Load (BTL)
s Fixed gain of 30 dB in Single-Ended (SE) and 36 dB in Bridge-Tied Load (BTL)
s High output power
s High supply voltage ripple rejection
s Internal switching frequency can be overruled by an external clock
s Full short-circuit proof across load and to supply lines
s Thermally protected
3. Applications
s Television sets
s Home-sound sets
s Multimedia systems
s All mains fed audio systems
s Car audio (boosters)
