| VREFP |
N/A |
This pin can be tied to an external 1.024V accurate reference IC for
best performance of the ADC. When there is no external reference,
connected to GND_SMON. |
| VREFN |
N/A |
For best performance of the ADC, tied this pin to the ground pin of an
external 1.024V accurate reference IC. This pin should always be
connected to GND_SMON even if an external reference is not
supplied. |
| VP |
Input |
This is the positive input terminal of the
dedicated differential analog input channel (VP/VN). When not used,
tie to GND_SMON. |
| VN |
Input |
This is the negative input terminal of the
dedicated differential analog input channel (VP/VN). When not used,
tie to GND_SMON. |
