input resistance of the ADC pin

nRF52832: how much is input resistance of the ADC pin? thanks!

Hi,

 

Please see this thread:

https://devzone.nordicsemi.com/f/nordic-q-a/37680/nrf52840-what-is-the-input-impedance-of-the-adc-inputs-in-spec-it-is-greater-than-1m-but-how-much

 

This is for the nRF52840, but will be equal for the nRF52832, as both GPIO pads and SAADC peripheral is equal on those.

 

Kind regards,

Håkon
