Bandgap reference output - nRF52832

[Henrik]

Hi,

The comparator (COMP) in nRF52 can use three internal reference voltages (1.2, 1.8 and 2.4V). Is it possible to also output these voltages on IOs?

Best regards Henrik

Hi Henrik

You can not output the internal reference voltage on a pin unfortunately.

The only alternative I can think of is to generate an external reference voltage, and configure the COMP module to use this reference instead of the internal one.

Hi Torbjörn,

Ah, as I feared then. Well, thanks for the answer!
