TDA8933_1
Preliminary data sheet
8.1 General
Table 3.
The TDA8933 is a mono full bridge or stereo half bridge audio power amplifier using
class-D technology. The audio input signal is converted into a Pulse Width Modulated
(PWM) signal via an analog input stage and PWM modulator. To enable the output power
Diffusion Metal Oxide Semiconductor (DMOS) transistors to be driven, this digital PWM
signal is applied to control and handshake block and driver circuits for both the high side
and low side. A 2nd-order-low-pass filter converts the PWM signal to an analog audio
signal across the loudspeakers.
The TDA8933 contains two independent half bridges with full differential input stages. The
loudspeakers can be connected in the following configurations:
The TDA8933 contains circuits common to both channels, such as: the oscillator, all
reference sources, the mode functionality and a digital timing manager.
The following protections are built-in: thermal foldback, temperature, current and voltage.
