Note 1: Absolute maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2: Linearity and monotonicity are defined from code k
2
rounded to the nearest whole code. For V
256 and linearity is defined from code 256 to code 65,535.
Note 3: SDA, SCL at 0V or V
Note 4: Inferred from measurement at code k
scale.
Note 5: V
and 3/4 scale to 1/4 scale. Load is 2k in parallel with 200pF to GND.
