Problem with "saadc" example (nRF52840 PDK)

Hi there,



I'm testing the "saadc" example : <InstallFolder>\examples\peripheral\saadc

I haven't changed the code.

To do this, I use the nRF52840 with SDK 14.2 and s140 softdevice.

The nRF52840 is powered by a USB cable.

To observe the values, I use a terminal emulator (PuTTY). Then, I use an external power supply on AIN0 that I vary between 0 and 3.6V to observe the numerical value on the console.

Everything is going well, until my measured voltage exceeds 2.1V. You can see this in the next capture:

I would like the curve to remain linear up to 3.6V. Do you have an idea for solving my problem?

Thank you in advance for your answers!
