Hi,

I'm planning on using a MKL17 64 pin device for a new design.

I want to connect VREFH to an external accurate reference (over temperature).

I cannot seem to find the minimal and maximal VREFH voltages with respect to Vdda in the datasheet.

Does anybody know where the VREFH/VREFL minimal and maximal operating conditions are specified?

Best regards,

Koen

Sorry we do not have the data regarding the minimal and maximal VREFH voltages with respect to Vdda. Only we provide is the the VREFH min 1.13V and max VDDA. The ADC will have correct value when working within this range.

Hi Fang,

Thanks for your response.

Where did you get these values from? Could you provide the document ID?

Thanks,

Koen

Hi Crystin,

Thanks.

Since I was planning on using the 32kb device I looked in that datasheet, there is no mention of the Vrefh range in that version though.
