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) Philips Semiconductors TDA8920B 2 × 100 W class-D power amplifier 4.
