Part Number: TAS5805M

Dear Sir,

We would like to change RAMP_PHASE_SEL when TAS5805M is active because to confirm the effect of each mode.

We try to send via I2C to change PHASE mode.

But It behaves unexpectedly in us.

・Phase change occur when I2S_SYNC_EN is disable.

・The actual parameter I changed are different from set value every time

Is it not supposed to change value when TAS5805M is active ?

Best regards,

Hi Kenta

Phase control is supposed to do during Startup Phase, and please follow the procedure according to the Datasheet. Change it casually may not get the results you want.

Dear Shadow,

Thank you for your reply.

> Change it casually may not get the results you want.

You means when phase control is setting during other startup phase, it may not get the results we want, don't you ?

Best regards,
