1) No missing codes.
2) Calibration should be preformed at each power-up. In case of a continous operation, it should be performed
minimium once per week.
3) The offser error voltage drifts over the whole temperature range maximum +-3LSB.
4) The accuracy values is valid between 5% and 90%of V_AINF
5) Voltage overshoot to 4V is permissible, provided the pulse duration is less than 100 μs and the cumulated sum
of the pulses does not exceed 1 h.
6) A running conversion may become inexact in case of violating the nomal operating conditions (voltage
overshoots).
The calibration procedure should run after each power-up, when all power supply
voltages and the reference voltage have stabilized.
