Can the nRF52832 analog input pin input negative voltage, for example from -3v to +3v, can the ADC indentify the voltage?

I want to use the nRF52832 real time monitoring the input voltage vary from -3v to +3v, and print the value by UART

Hi,

you need a shift-and-scale unit like this to convert -3..+3V range into 0..VDD.
