Hey Buddy,

I was but it's kind of tricky. You probably installed the SparkFun Board via Board Manager in Arduino but the thing is, the nRF5 Core in SparkFuns Files is an old one.

So heres the deal:

1. Get the nRF52 Core from Github or download the stuff for the Adafruit Feather nRF52: https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/arduino-bsp-setup

2. You'll find the Core Files under: Library > Arduino15 > packages...

3. Take the files (wiring_analog.h & wiring_analog_nRF52.c) from adafruit and copy them in to your SparkFun packages folder and replace them (better safe the old ones first)

4. Give it a try, take the commands found in the link above (nrf52-adc)

Have Fun Bro

were you successful in using analogReference(AR_INTERNAL_3_0);?

I have the same board as you and I'm currently having issues trying to change the reference voltage to 3.0V

Edit: for interesting, Is there a way to use an external reference for the analog Input?
