The TPA3136D2 Class D audio power amplifier is the latest TI analog input amplifier that uses advancedPWM switching techniques for reducing electromagnetic interference (EMI) without degrading audioperformance. This application note describes the system design and printed circuit board (PCB) guidelinesused to maximize the technology employed in the TPA3136D2 device. These techniques include the EMIsuppression without the need for expensive inductor filters and the reduction of external component count.
