Gain Error
The deviation from the nominal full scale output for a full scale input.
Gain Drift
The change in gain value with temperature. Units in ppm/°C.
Offset Error
For the ADCs, the deviation in LSBs of the output from mid-scale with the selected input
grounded. For the DACs, the deviation of the output from zero (relative to CMOUT) with mid-
scale input code. Units are in Volts.
