TDA8920C 2 110 W class-D power amplier Rev. 02 11 June 2009 Product data sheet 1. General description The TDA8920C is a high-efciency class-D audio power amplier. The typical output power is 2 110 W with a speaker load impedance of 4 . The TDA8920C is available in both HSOP24 and DBS23P power packages. The amplier operates over a wide supply voltage range from 12.5 V to 32.5 V and features low quiescent current consumption. 2. Features n Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages n Symmetrical operating supply voltage range from 12.5 V to 32.5 V n Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplier n High output power in typical applications: u SE 2 110 W, R =4 (V = 30 V) L P u SE 2 125 W, R =4 (V = 32 V) L P u SE 2 120 W, R =3 (V = 29 V) L P u BTL 1 220 W, R =8 (V = 30 V) L P n Low noise n Smooth pop noise-free start-up and switch off n Zero dead time switching n Fixed frequency n Internal or external clock n High efciency n Low quiescent current n Advanced protection strategy: voltage protection and output current limiting n Thermal FoldBack (TFB) n Fixed gain of 30 dB in SE and 36 dB in BTL applications n Fully short-circuit proof across load n BD modulation in BTL conguration 3.
