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 .
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 (VP = ±30 V)
N SE 2 × 125 W, RL = 4 (VP = ±32 V)
N SE 2 × 120 W, RL =3 (VP = ±29 V)
N BTL 1 × 220 W, RL =8 (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
I DVD
I Mini and micro receiver
I Home Theater In A Box (HTIAB) system
I High-power speaker system
