Part Number: TAS2557

Hi, 

We want to use TAS2557 in a mobile phone to drive the speaker in handsfree mode.

  • We plan to use only 1 I2S connection(ASI1). We plan to enable only Speaker Excursion Protection, Speaker Temperature protection and Speaker Overdrive based on speaker coil temperature. Is that possible?
  • In voice call use case, since we are not using second I2S port, will there be any impact on echo cancellation that happens on the host ?
  • Since we are not enabling other sound enhancement algos in TAS2557, is the output data from second ASI2 port required for application?

Appreciate your quick response.

Thanks,

Naveen
