Product data sheet

1. General description

The TDA8922C is a high-efficiency Class D audio power amplifier. Typical output power is

2 × 75 W with a speaker load impedance of 6 Ω.

The TDA8922C 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 TDA8950/20C 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 × 75 W, RL = 6 Ω (VDD = 30 V; VSS = −30 V)

N SE 2 × 60 W, RL = 8 Ω (VDD = 30 V; VSS = −30 V)

N BTL 1 × 155 W, RL = 8 Ω (VDD = 25 V; VSS = −25 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
