TDA8953

The TDA8953 is designed as one kind of stereo or mono high-efficiency Class D audio power amplifier device that combines the benefits of Class D efficiency with audiophile sound quality comparable to that associated with Class AB amplification. 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; (5)Public Address (PA) system; (6)Subwoofers applications.

Features of the TDA8953 are:(1)Symmetrical operating supply voltage range from +/-2.5 V to +/-2.5 V; (2)Stereo full differential inputs, can be used as stereo SE or mono BTL amplifier; (3)Low noise; (4)Smooth pop noise-free start-up and switch off; (5)Fixed frequency internal or external clock; (6)High efficiency ?3 %; (7)Zero dead time switching; (8)Low quiescent current; (9)Advanced protection strategy: voltage protection and output current limiting; (10)Thermal FoldBack (TFB) with disable functionality; (11)Fixed gain of 30 dB in SE and 36 dB in BTL applications; (12)Fully short-circuit proof across load; (13)BD modulation in BTL configuration; (14)Clock protection.

The absolute maximum ratings of the TDA8953 can be summarized as:(1)positive supply voltage: 12.5 to 42.5 V;(2)overvoltage protection supply voltage: 85 to 90 V;(3)total quiescent current: 50 to 60 mA;(4)output power: 150 to 210 W;(5)negative supply voltage.
