General description
●The TDA8922C is a high-efficiency Class D audio power amplifier. Typical output power is 2×75 W with a speaker load impedance of 6Ω. The TDA8922C 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.
●Features
●Pin compatible with TDA8950/20C 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 2×75 W, RL=6Ω(VDD=30V; VSS=−30 V)
● SE 2×60 W, RL=8Ω(VDD=30V; VSS=−30 V)
● BTL 1×155 W, RL=8Ω(VDD=25V; VSS=−25 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
