Hi all,

    Agni,

    As far as the equation on Page 33 goes, the denominator would change to 2^12 and the addition in the numerator would become 2^11. Basically the User_GAIN field becomes referred to mid-scale 12-bit code as the zero-point in straight binary.

    Like the data register, the calibration register uses the upper MSBs for the 12-bit value.
