Hi,
We are using the DRV5825P EVM for piezo speaker PHUA2010-049B-00-000 testing. But the output is a bit noisy. Is there any application note/ tuning guide which can help us to fine tune the values please let us know.
Best Regards,
Shubham

Hi Shubham
i am not sure what kind of noise you mean.
usually, we can have below several step to avoid the noise.
1. confirm whether the clipping is happen.
2. confirm noise happen at which frequency, we can use EQ or DRC to suppress that range to avoid noise.
3. use smaller gain to avoid to large output so that piezo cannot suffer.
you can refer below doc for some tuning model like gain config, DRC, AGL.
tks
