TAS5760MD: Output waveform strange

Part Number: TAS5760MD
Other Parts Discussed in Thread: TAS5760XXEVM

Hi Ti,

Recently, i am studying TAS5760MD, and buying a TAS5760xxEVM, and when i check the output waveform at OUTA+, and OUTA-, the phase is the same(referred the attached file), so why the phase is the same?

Thanks.

Hi Hsieh,

As Kato mentioned, it seems like that the TAS5760MD device you have was running in PBTL mode after power-up.

Toggling the /SDK_SD bit should be able to fix that issue.
