Note 1: Values at T_A = +25°C to +85°C are guaranteed by production test. Values at T_A < +25°C are guaranteed by design and
characterization.
Note 2: Static linearity and offset parameters are computed from a best-fit straight line through the code transition points.
The full-scale range (FSR) is defined as 4095 x slope of the line.
Note 3: Parameter guaranteed by design and characterization; T_A = -40°C to +85°C.
Note 4: ENOB and SINAD are computed from a curve fit.
Note 5: PSRR is measured with the analog and output supplies connected to the same potential.
