TDA8933

Class-D audio ampliﬁer

Rev. 01 — 15 May 2007

Preliminary data sheet

1. General description

The TDA8933 is a high efﬁciency class-D ampliﬁer with low power dissipation.

The continuous time output power is 2 × 10 W in a stereo half bridge application

(R_L= 8 Ω) or 1 × 20 W in a mono full bridge application (R_L=16 Ω). Due to the low power

dissipation the device can be used without any external heat sink when playing music.

Due to the implementation of Thermal Foldback (TF), even for high supply voltages and/or

lower load impedances, the device will continue to operate with considerable music output

power without the need for an external heat sink.

The device has two full differential inputs driving two independent outputs. It can be used

in a mono full bridge conﬁguration (Bridge-Tied Load (BTL)) or a stereo half bridge

conﬁguration (Single-Ended (SE)).

2. Features

I High efﬁciency

I Full short circuit proof to supply lines (using advanced current protection)

I Switchable internal / external oscillator (master-slave setting)

I No pop noise

I Low power dissipation

I Mono bridge-tied load (full bridge) or stereo single-ended (half bridge) application

I Full differential inputs

3. Applications

I Flat panel television sets

I Flat panel monitor sets

I Multimedia systems
