1) Calibration of the gain is possible for the gain of 1 and 2, and not possible for the gain of 4 and 8.
2) Callibration should be performed at each power-up. In case of continuous operation, callibration should be
performed minimum once per week.
3) The offset error voltage drifts over the whole temperature range typically ±2 LSB.
4) Applies when the gain of the channel equals one. For the other gain settings, the offset error increases; it must
be multiplied with the applied gain.
5) The leakage current definition is a continuous function, as shown in Figure 4-5. The numerical values defined
determine the characteristic points of the given continuous linear approximation - they do not define step
function.
6) Only one of these parameters is tested, the other is verified by design characterization.
7) Voltage overshoot to 4 V are permissible, provided the pulse duration is less than 100 µs and the cumulated
summary of the pulses does not exceed 1 h.
8) Voltage overshoot to 1.7 V are permissible, provided the pulse duration is less than 100 µs and the cumulated
sum of the pulses does not exceed 1 h.
9) A running conversion may become inexact in case of violating the normal operating conditions (voltage
overshoots).
10) Current peaks of up to 40 mA with a duration of max. 2 ns may occur
