General description

The TDA8950 is a high-efﬁciency Class D audio power ampliﬁer. The typical output power

is 2

× 150 W with a speaker load impedance of 4 Ω.

The TDA8950 is available in both HSOP24 and DBS23P power packages. The ampliﬁer

operates over a wide supply voltage range from

±12.5 V to ±40 V and features low

quiescent current consumption.

2.

Features

I Pin compatible with TDA8920B for both HSOP24 and DBS23P packages

I Symmetrical operating supply voltage range from ±12.5 V to ±40 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 × 150 W, RL =4 Ω (VP = ±37 V)

N SE 2 × 170 W, RL =4 Ω (VP = ±39 V)

N SE 2 × 100 W, RL =6 Ω (VP = ±37 V)

N BTL 1 × 300 W, RL =8 Ω (VP = ±37 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
