We designed SSM2603 in few years ago. Recently , We find some spec problem about Microphone Boost function.
In SSM2603 datasheet revision A , the microphone boost include MICBOOST_1/BOOST2 , 40dB MIC gain will boost from SSM2603. but , in SSM2603 datasheet revision B , the boost only include 20 dB and control by MICBOOST(Register R4 , D0).
Can any one help to calify this, since we already design SSM2603 in lot of project , we need to confirm if any risk for this function.
