What is the tolerance of the internal ADC 0.6V reference voltage?

[EdwardC]

What is the tolerance of the internal ADC 0.6V reference voltage for NRF52840?

i.e. what's the max/min of the 0.6V reference or what's it in percentage?

Where can this information be obtained?

Many Thanks

Thank you Jared for your reply.

I just found another thread saying different value, https://devzone.nordicsemi.com/f/nordic-q-a/80315/nrf52840-adc-internal-reference-voltage-0-6v-accuracy-at-room-temperature

May you please confirm that? 

Is there any published documentation regarding the tolerance of the internal ADC 0.6V reference voltage?

Many thanks,

Edward

Hi there,

I just doubled checked and the correct information is actually +/- 0.2 %. We do not have any public documents on this.

I'm sorry for the confusion.
