TDA8922C 2 75 W class-D power amplier Rev. 01 7 September 2009 Product data sheet 1. General description The TDA8922C is a high-efciency Class D audio power amplier. Typical output power is 2 75 W with a speaker load impedance of 6 . The TDA8922C 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 TDA8950/20C 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 75 W, R =6 (V =30V V = - 30 V) L DD SS u SE 2 60 W, R =8 (V =30V V = - 30 V) L DD SS u BTL 1 155 W, R =8 (V =25V V = - 25 V) L DD SS 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. Applications n DVD n Mini and micro receiver n Home Theater In A Box (HTIAB) system n High-power speaker systemTDA8922C NXP Semiconductors 2 75 W class-D power amplier 4.
