1-1 Introduction The true digital audio amplifiers (TDAA) system consists of a PCM–PWMmodulator device and a PWM power output device. The PCM–PWMprocessor accepts a serial PCM digital audio stream and converts it to a 3.3-VPWM audio stream. The TDAA output stage provides a large-signal PWMoutput. Th...
