TDA8950

The TDA8950 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 ±40 V and features low quiescent current consumption. Also it 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 TDA8950 are:(1)Low noise; (2)Smooth pop noise-free start-up and switch off; (3)Zero dead time switching; (4)Fixed frequency; (5)Internal or external clock; (6)High efficiency; (7)Low quiescent current; (8)Advanced protection strategy: voltage protection and output current limiting; (9)Thermal FoldBack (TFB); (10)Fixed gain of 30 dB in SE and 36 dB in BTL applications; (11)Fully short-circuit proof across load; (12)BD modulation in BTL configuration; (13)Pin compatible with TDA8920B for both HSOP24 and DBS23P packages; (14)Symmetrical operating supply voltage range from ±12.5 V to ±40 V; (15)Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier.

The absolute maximum ratings of the TDA8950 can be summarized as:(1)supply voltage: ±12.5 to ±40 V;(2)overvoltage protection supply voltage: 85 to 90 V;(3)total quiescent current: 50 to 75 mA;(4)output power: 100 to 170 W.
