Note 1: Static linearity and offset parameters are computed from a best-fit straight line through the code transition points. The full-
scale range is defined as 1023 x slope of the line.
Note 2: Parameter guaranteed by design and characterization; T
A = T MIN to T MAX .
Note 3: PSRR is measured with both analog and digital supplies connected to the same potential.
