| VREFP |
N/A |
This pin can be tied to an external 1.024V
accurate reference IC for best performance of the ADC. This pin
should be connected to GND_SMON if an external reference is not
supplied. |
| VREFN |
N/A |
This pin should be tied to the ground pin of an
external 1.024V accurate reference IC for best performance of the
ADC. 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. |
