Part Number: TPA3116D2
Although there is only one audio power amplifier chip in our design, the load is far from the chip, and common-mode signals risk interfering with the analog circuit. To prevent the audio power amplifier from interfering with the analog circuit, we set the TPA3116 to slave mode, and the MCU outputs a clock to SYNC. By modifying the PWM frequency, we aim to resolve the interference of the audio power amplifier on the analog front-end. Therefore, we would like to know the frequency range supported by SYNC.
