Hi NXP Community,
I have to perform the acquisition of a differential signal (AP-AN) coming form an OPAMP using S32K 100pin MCU.
Both signals AN & AP are in the range of VREFH and VREFL. What is the best option to connect them to the MCU and reach the best accuracy:
Option 1: Use 2 adjacent pins, standard channels from different ADC module ADC0 and ADC1
Option 2: Use 2 adjacent pins, precision channels from the same ADC module ADC0 or ADC1
Thank you in advance for your support.
