TDA8953 2 210 W class-D power amplifier Rev. 01 24 December 2009 Product data sheet 1. General description The TDA8953 is a stereo or mono high-efficiency Class D audio power amplifier in a single IC featuring low power dissipation. It is designed to deliver up to 2 210 W into a 4 load in a stereo Single-Ended (SE) application, or 1 420 W into an 8 load in a mono Bridge-Tied Load (BTL) application. It combines the benefits of Class D efficiency (93 % into a 4 load) with audiophile sound quality comparable to that associated with Class AB amplification. The amplifier operates over a wide supply voltage range from 12.5 V to 42.5 V and features low quiescent current consumption. 2. Features High output power in typical applications: SE 2 210 W, R = 4 (V = 41 V V = 41 V) L DD SS SE 2 235 W, R = 3 (V = 39 V V = 39 V) L DD SS SE 2 150 W, R = 6 (V = 41 V V = 41 V) L DD SS BTL 1 420 W, R = 8 (V = 41 V V = 41 V) L DD SS Symmetrical operating supply voltage range from 12.5 V to 42.5 V Stereo full differential inputs, can be used as stereo SE or mono BTL amplifier Low noise Smooth pop noise-free start-up and switch off Fixed frequency internal or external clock High efficiency 93 % Zero dead time switching Low quiescent current Advanced protection strategy: voltage protection and output current limiting Thermal FoldBack (TFB) with disable functionality Fixed gain of 30 dB in SE and 36 dB in BTL applications Fully short-circuit proof across load BD modulation in BTL configuration Clock protectionNXP Semiconductors TDA8953 2 210 W class-D power amplifier 3.
