[quote userid="81557" url="~/f/nordic-q-a/49658/nrf52832-questions-about-the-analog-to-digital-convertion/197929"] I looked through the product specification sheet[/quote]

Perhaps you were just looking at the Product Brief ... ?

Yes I just saw it. I was able to find the power consumption I think. It said the current drawn from the Analog to Digital converter during conversion is 260 micro amperes. I assume that is how much power the Analog to Digital converter uses during conversion.

Also, I looked through the product specification sheet and could not find a block diagram or a circuit diagram of the Analog to Digital converter.

Also, I saw the input range and was wondering what is the input range of voltage so that it can be converted in the Analog to Digital converter. I think it said 0.83-1.3 V but it is not clear.

Did you study the section in the Product Specification about it ... ?

There's certainly a block diagram there
