nRF54L15 ADC Rsource value

[Poki Huang]

Hi 

I want to check the nRF54L15 ADC Rsource value

As below pic., P1.07/AIN3 input voltage will be 0.6V (1.8V divider by R429 & R428)

So the Rsource value will be R429//R428 value(~666Kohm) or R429+R428 value(3Mohm)?

Thank you

Hi

By your provided link (https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/measuring-lithium-battery-voltage-with-nrf52 )

Rsource value only take R1, no R2

So I have one question, if we only mount R2, R1 un-mount, what is the Rsource value?

Thank you
