Functional description
8.1 General
The TDA8950 is a two-channel audio power amplifier using class-D technology.
The audio input signal is converted into a digital pulse width modulated signal via an
analog input stage and PWM modulator, see Figure 1. To enable the output power
transistors to be driven, this digital PWM signal is applied to a control and handshake
block and driver circuits for both the high side and low side. In this way a level shift is
performed from the low power digital PWM signal (at logic levels) to a high power PWM
signal that switches between the main supply lines.
A 2nd-order low-pass filter converts the PWM signal to an analog audio signal across the
loudspeakers.
