I want to connect one Gefran Linear Potentiometer with Beaglebone Black for displacement measurement purpose. The signal conditioner of the Lin. Pot. gives and output of 0-10 V. I am using a simple voltage divider circuit of 8.2K 0.1% resistor and 1K 0.1% resistor. Now I can either feed the voltage across 1K resistor to the analog input pin of beaglebone. Otherwise, as I understand, I can connect an external ADC to the output of the 1K resistor and then the ADC can be connected to Beaglebone Black. In the second case, I do not lose out in resolution provided I use a 24bit ADC. Beaglbone Black's internal ADC has a lower resolution. Which ADC should I use for this application? Can anybody help me with the circuit diagram for connecting the ADC with beaglebone and the voltage divider circuit?
