TDA8920C

2 × 110 W class-D power amplifier

Rev. 01 — 29 September 2008

Preliminary 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 has a low

quiescent current consumption.

2. Features

I Pin compatible with TDA8950/20B for both HSOP24 and DBS23P packages

I Symmetrical high operating supply voltage range from ±12.5 V to ±32.5 V

I Stereo full differential inputs, usable as stereo Single-Ended (SE) or mono Bridge-Tied

Load (BTL) amplifier

I High output power at 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 × 210 W, RL = 8 Ω (VP = ±30 V)

I Low noise in BTL operation due to BD modulation

I Smooth pop noise-free start-up and switch off

I Zero dead time Pulse-Width Modulation (PWM) output switching

I Fixed frequency

I Internal or external clock switching frequency

I High efficiency

I Low quiescent current

I Advanced protection strategy: voltage protection and output current limiting

I Thermal foldback

I Fixed gain of 30 dB in SE and 36 dB in BTL

I Full short-circuit proof across load

3. Applications

I DVD

I Mini and micro receiver

I Home Theater In A Box (HTIAB) system

I High power speaker system
