TDA8922C

TDA8922C 2 × 75 W class-D power amplifier Rev. 01 — 7 September 2009 Product data sheet 1. General description The TDA8922C is a high-efficiency Class D audio power amplifier. Typical output power is 2 × 75 W with a speaker load impedance of 6 Ω. The TDA8922C is available in both HSOP24 and DBS23P power packages. The amplifier operates over a wide supply voltage range from ±12.5 V to ±32.5 V and features low quiescent current consumption. 2. Features I Pin compatible with TDA8950/20C for both HSOP24 and DBS23P packages I Symmetrical operating supply voltage range from ±12.5 V to ±32.5 V I Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier I High output power in typical applications: N SE 2 × 75 W, RL = 6 Ω (VDD = 30 V; VSS = −30 V) N SE 2 × 60 W, RL = 8 Ω (VDD = 30 V; VSS = −30 V) N BTL 1 × 155 W, RL = 8 Ω (VDD = 25 V; VSS = −25 V) I Low noise I Smooth pop noise-free start-up and switch off I Zero dead time switching I Fixed frequency I Internal or external clock I High efficiency I Low quiescent current I Advanced protection strategy: voltage protection and output current limiting I Thermal FoldBack (TFB) I Fixed gain of 30 dB in SE and 36 dB in BTL applications I Fully short-circuit proof across load I BD modulation in BTL configuration 3.
