Are you able to reproduce the issue on the nRF7002DK or nRF5340DK? If so, please upload the simple project to reproduce the issue on the nRF7002DK or nRF5340DK. That means uploading the source code and configuration.

Seems the issue might be the hardware. Please make sure to use the correct pins for AIN0 and AIN1 on your custom board.

I'm using custom board (nrf5340 + nrf7002).
When sdk was used in SES with the same configuration as the rest of the circuit except mcu (using nRF52833), this problem did not occur.
Does providing a simple project for nRF5340DK mean uploading source code?

Are you using a custom board or nRF5340DK? Do you see the same issue on nRF5340DK? Could you test with pins tied to VDD or GND? Please provide a simple project for nRF5340DK to help reproduce the issue.

The explanation seems insufficient.
Are you saying that these settings are the cause of the change in the value of AIN1 that is not input according to the input value of AIN0?

Hi,

You can refer to boards/nrf52840dk_nrf52840.overlay for an example of such a setup.
