Bryan, It's likely that the ADS1115 is close to what you want. To be sure, I think it would be best to go through what you have in mind for your system. If your measurement is a voltage that goes from 0 to 5V, then the ADS1115 will need to be operated in the ±6.144V input range. In that case, your measurement will be represented by 26667 total codes. I get this from [5V/(2*6.144)]*2^16. If you are trying to represent 360° in 0.01° increments, you would need 36000 codes. This is close to what you want, but might be short. Can you post the schematic and more information about what you want to try to measure? There is probably a simple way to construct this, but I'll need to know more about your system. How do you measure the precision potentiometer? Do you drive the potentiometer with a known reference current? Post how you think your system will be constructed, and we can discuss the details.
