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 features low quiescent current consumption.

2. Features

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

■ Symmetrical operating supply voltage range from ±12.5 V to ±32.5 V

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

Bridge-Tied Load (BTL) amplifier

■ High output power in typical applications:

◆ SE 2 × 110 W, RL = 4 Ω (VP = ±30 V)

◆ SE 2 × 125 W, RL = 4 Ω (VP = ±32 V)

◆ SE 2 × 120 W, RL = 3 Ω (VP = ±29 V)

◆ BTL 1 × 220 W, RL = 8 Ω (VP = ±30 V)
