NOTES:

1. The leakage current for the Comparator_A+ terminals is identical to Ilkg(Px.x) specification.

2. The input offset voltage can be cancelled by using the CAEX bit to invert the Comparator_A+ inputs on successive measurements.

The two successive measurements are then summed together.

3. Response time measured at P1.3/CAOUT.
