The TDA8920C is a high-efficiency class-D audio power amplifier. The typical output power is 2 x 110 W with a speaker load impedance of 4 O. The TDA8920C is available in both HSOP24 and DBS23P power packages. The amplifier operates over a wide supply voltage range from +-12.5 V to +-32.5 V and features low quiescent current consumption.
- Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages
- Symmetrical operating supply voltage range from +-12.5 V to +-32.5 V
- Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier
- High output power in typical applications:
- SE 2 x 110 W, RL = 4 O (VP = +-30 V)
- SE 2 x 125 W, RL = 4 O (VP = +-32 V)
- SE 2 x 120 W, RL = 3 O (VP = +-29 V)
- BTL 1 x 220 W, RL = 8 O (VP =+-30 V)
- Low noise
- Smooth pop noise-free start-up and switch off
- Zero dead time switching
- Fixed frequency
- Internal or external clock
- High efficiency
- Low quiescent current
- Advanced protection strategy: voltage protection and output current limiting
- Thermal FoldBack (TFB)
- Fixed gain of 30 dB in SE and 36 dB in BTL applications
- Fully short-circuit proof across load
- BD modulation in BTL configuration
