Hi,
I am using the nRF52840 chip and supply iam giving from coin cell(3V). So i want to measure the coin cell voltage level monitor with nrf52840 ADC pin.
kindly provide the circuit for the same.

Hi,
you can configure ADC to measure voltage directly at VDD pin, without any external components, using an internel 0.6V reference.
