TDA8922C

The TDA8922C is designed as one kind of high-efficiency class-D audio power amplifier device that 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. Also this device can be used in (1)DVD; (2)Mini and micro receiver; (3)Home Theater In A Box (HTIAB) system; (4)High-power speaker system applications.

Features of the TDA8922C are:(1)Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages; (2)Symmetrical operating supply voltage range from ±12.5 V to ±32.5 V; (3)Stereo full differential inputs, can be used as stereo Single Ended (SE) or mono Bridge-Tied Load (BTL) amplifier; (4)Low noise; (5)Smooth pop noise-free start-up and switch off; (6)Zero dead time switching; (7)Fixed frequency; (8)Internal or external clock; (9)High efficiency; (10)Low quiescent current; (11)Advanced protection strategy: voltage protection and output current limiting; (12)Thermal FoldBack (TFB); (13)Fixed gain of 30 dB in SE and 36 dB in BTL applications; (14)Fully short-circuit proof across load; (15)BD modulation in BTL configuration.

The absolute maximum ratings of the TDA8922C can be summarized as:(1)supply voltage: ±12.5 to ±32.5 V;(2)overvoltage protection supply voltage: 65 to 70 V;(3)total quiescent current: 50 to 75 mA;(4)output power: 110 or 90 W.
