MK10DX128VLH7 ADC issue

I have some code running on an MK10DX128VLH5 processor without issues.  We had supply chain issues and swapped to MK10DX128VLH7.  I am having a problem with pin 12 (ADC0_DM3 adc channel 21).  The readings are all over the place.  On the VLH5 all is good.  I am also using pins 11, 10, and 9 without an issue.  The VLH7 differs in that it has ADC1 as well.  On that particular pin (12) I used ADC1_DM3 (adc channel 19) and the readings are good.  So the same pin, just different ADC and channel.  Is there some errata that is not published or I didn't see.

Hi

there are some erratas on the next link

https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/general-purpose-mc...

 

and those are all of them

what kind of problem do you have?

what happens if you add some time between the measurements? 

Have a good day.
