Although the voltage control is rated at 5.5VDC, my experience is that the actual limit is going to be closer to 5.2VDC unless you carefully control you power bus to avoid transient surges, etc. Analog inputs have a lower limit (1.8VDC), so just use Port 9 Pin 32 as your voltage source, if your analog sensor can work on 1.8V. Otherwise, use a voltage divider or bidirectional logic level converter to stay under the limits.
