My plan in the below circuit was to use a voltage divider from a Max6225 2.5Vref, to get 2V and 1V from it in order to use the full 16bit bipolar scale of the ADS1115s, but I'm getting strange resistance readings from a DMM across the resistors - can I use a voltage divider with the Vref like this?
EDIT: Apologies for the drawing - not sure how to do the buried zener vref part, so I've marked the connections instead OK.
EDIT 2: Please ignore the test resistor in the bottom picture - this was just to test if the same thing happened however I connected a resistance from Vref out back to ground, rather than a short or something on the board
