"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 4Ω.
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 has a low quiescent current consumption.

Features:

Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages
Symmetrical high operating supply voltage range from ±12.5 V to ±32.5 V
Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-Tied Load (BTL) amplifier
High output power at typical applications:
SE 2×110 W, RL= 4Ω(VP= ±30 V)
SE 2×125 W, RL=4Ω(VP= ±32 V)
SE 2×120 W, RL= 3Ω (VP= ±29 V)
BTL 1×210 W, RL= 8Ω (VP= ±30 V)

Low noise in BTL operation due to BD modulation
Smooth pop noise-free start-up and switch off
Zero dead time Pulse-Width Modulation (PWM) output switching
Fixed frequency
Internal or external clock switching frequency
High efficiency
Low quiescent current
Advanced protection strategy: voltage protection and output current limiting
Thermal foldback
Fixed gain of 30 dB in SE and 36 dB in BTL
Full short-circuit proof across load

Applications:

DVD
Mini and micro receiver
Home Theater In A Box (HTIAB) system
