Offset error is defined as the output code error for a zero volt input (ideally, output code = 0). The offset of the ADC and the
PGA1 stage are completely suppressed if N
The measured offset drift vs. temperature curves for different PGA gains are depicted in Figure 41. The output offset error,
expressed in LSB for 16-bit setting, is normalized to 25°C. Notice that if the ADC is used alone, the output offset error is
below +/-1 LSB and has no drift.
