TDA8920C
2 × 110 W class-D power amplifier
Rev. 02 — 11 June 2009 Product data sheet
1. General description
The TDA8920C is a high-efficiency class-D audio power amplifier. The typical output power is 2 × 110 W with a speaker load impedance of 4 Ω. The TDA8920C 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 TDA8950/20B 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 × 110 W, RL = 4 Ω (VP = ±30 V) N SE 2 × 125 W, RL = 4 Ω (VP = ±32 V) N SE 2 × 120 W, RL =3 Ω (VP = ±29 V) N BTL 1 × 220 W, RL =8 Ω (VP = ±30 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. Applications
