ADC reference voltage details
Added by Raja Vankam over 10 years ago
We are in the process of designing signal conditioning circuitry for ADC. Could please let us know what is ADC reference voltage.
I couldnt get quite well this info from the data sheet.

The AIN[0:7] ADC reference voltages are set by VREFN and VREFP of the AM3359. Those pins are brought out to the edge connector (pins 176 and 178) and are direct connects to the AM3359 (there are some bypass caps to AGND on the board). You can set the VREFN and VREFP to your application requirements as long as you stay within the specifications of the AM3359. The VDDA_ADC is connected to a 1.8V supply.
Is this what you are looking for?
