TDA8954 2 × 210 W class-D power amplifier
www.nxp.comThe TDA8954 is a two-channel audio power amplifier that uses Class D technology. For each channel, the audio input signal is co nverted into a digital Pulse Width Modulation (PWM) signal using an analog input stage and a PWM modulator; see Figure 1. To drive the output power transistors, the digital PWM signal is fed to a control and handshake
