TDA8920B; 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 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 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).
