ADCOVER[3:0]

ADC overrange threshold

An ADC out-of-range error is flagged if the ADC output is greater than the overrange

threshold; the overrange threshold is offset from the maximum value

Threshold = max_value – ADCOVER × 26

0000 = maximum value (disabled)

0001 = max_value − 64

0010 = max_value − 128

…

1111 = max_value − 960

LOFFUTH[15:0]

Applies to ac lead-off upper threshold only; lead-off is detected if the output is ≥ N ×

2 × VREF/GAIN/216

0 = 0 V

ADCUNDR[3:0]

ADC underrange threshold

An ADC out-of-range error is flagged if the ADC output is less than the underrange

threshold

Threshold = min_value + ADCUNDR × 26

0000 = minimum value (disabled)

0001 = min_value + 64

0010 = min_value + 128

…

1111 = min_value + 960

LOFFLTH[15:0]

Applies to ac lead-off lower threshold only; lead-off is detected if the output is ≤ N ×

2 × VREF/GAIN/216

0 = 0 V
