Hello,

You can use several inputs for the ADC. 

You can e.g. see the example that I attach here. It has 2x ADC on AIN0 and AIN1 (pin P0.02 and P0.03). The example works for both nRF52832 and nRF52840.

 

saadc_x2_test.zip

 

It works with SDK14.2.0, but I have not yet tested it for SDK15.0.0. The ADC values will show in the UART log, so open an UART terminal like Putty or Termite, and connect P0.02 to GND and P0.03 to VDD, and you can see the different values in the UART log.

Best regards,

Edvin
