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
