We are planning to use SSM2167 in one of our project.
Where output of MIC is connected to input of SSM2167 and output of SSM2167 is connected to Audio codec, we have tested with external setup by soldering this IC in general purpose board and it is working fine.
But, there is small amount of background noise which is always present irrespective of audio. This noise is not present, when we connect MIC output directly to audio codec by bypassing SSM2167.
Please suggest to resolve said issue at the earliest.
