How to measure Lithium battery voltage with the nRF51 ADC
Stefan, Thank you for the answer. My team and I are only planning to sample once a minute. So no issues on sampling rate. Does Nordic publish the approximate size on the internal ADC sampling cap? The setup you just suggested will work great for our current application, but in the future it might be nice to know the size of the internal cap. That way we could properly figure out what value the external cap needs to be.
Stefan,
Thank you for your attention to my questions. It is greatly appreciated. This is my first experience developing on a Nordic platform, and the design process has been made much easier through the help of you and the others you work with.
@bentruong : What voltage exactly are you asking about? Can you please clarify.
