TDA8920C

2 Ã 110 W class-D power ampliï¬er

Rev. 02 â 11 June 2009

Product data sheet

1. General description

The TDA8920C is a high-efï¬ciency class-D audio power ampliï¬er. The typical output

power is 2 Ã 110 W with a speaker load impedance of 4 â¦.

The TDA8920C is available in both HSOP24 and DBS23P power packages. The ampliï¬er

operates over a wide supply voltage range from Â±12.5 V to Â±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 Â±12.5 V to Â±32.5 V

I Stereo full differential inputs, can be used as stereo Single-Ended (SE) or mono

Bridge-Tied Load (BTL) ampliï¬er

I High output power in typical applications:

N SE 2 Ã 110 W, RL = 4 â¦ (VP = Â±30 V)

N SE 2 Ã 125 W, RL = 4 â¦ (VP = Â±32 V)

N SE 2 Ã 120 W, RL = 3 â¦ (VP = Â±29 V)

N BTL 1 Ã 220 W, RL = 8 â¦ (VP = Â±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 efï¬ciency

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 conï¬guration

3. Applications

I DVD

I Mini and micro receiver

I Home Theater In A Box (HTIAB) system

I High-power speaker system
