Notes:
1. Channel Accuracy includes prescaler and ADC accuracies. For 12-bit mode, multiply the LSB count by 4. For 8-bit
2. Requires enabling Analog Calibration using SmartGen Analog System Builder. For further details, refer to the
3. Calibrated with two-point calibration methodology, using 20% and 80% full-scale points.
4. The lower limit of the input voltage is determined by the prescaler input offset.
mode, divide the LSB count by 4. Overall accuracy remains the same.
