Hi ,

I met a question,

I've a test that used to analyze audio waveform, ex frequency drift.

basically, it based on analog output.

But TAS5754M is class D output.

Do you have any ideas to perform this kind of test?

Thanks,

Hi Paoheng,

You can analyze the analog output after the LC filter. Indeed, class D output is PWM, but LC filter will filter out the PWM and leave audio signal alone for your analyze.

As to what is the configuration of LC, please refer to the datasheet and EVM user's guide. See them by http://www.ti.com/product/TAS5754M/technicaldocuments

Alix Wan.
