%FS/V

Note 1. Resolution in bits is calculated as follows: VN_BIT=log(ISR / VN)/log(2) when VN is the RMS noise voltage.

Note 2. Linearity in bits is calculated as follows: INLBIT=log(CODELIN / INL)/log(2) when integral nonlinearity (INL) is calculated from best fit

line to linear input signal range containing 21 pcs analysis points.

Note 3. VDD sensitivity in %FS/V calculated as follows: VDDSENS =100%*((CODE @ VDDMAX) – (CODE @ VDDMIN))/CODEFS/(VDDMAX -

VDDMIN) where VDDMAX=3.6V and VDDMIN=1.9V when the regulator is enabled (ENREG=1). and set to VREG=1.8V (REGEB=00).
