"Honey, my PIC ADC pin sagged my peak detector voltage!"

[HankMcSpank]

Why don't you contact MCHP, inform them of your findings and have them confirm that the datasheet is in error (or perhaps the datasheet is correct and that you may have discovered a silicon error)?

For a few minutes I was overwhelmed by the onset of "global community spirit" to do the right thing ...so visited Microchip's website ...they've even produced a video about how to report back silicon errors.....I grew a beard to rival the guitarists in ZZ Top watching it, & then threw my wife's purse at the screen when it got to the bit about "& having followed the 11 steps we've just outlined, unless you attach scope traces we won't believe you & just assume you're a pleb"

I'm now hoping anyone similar 16f1828 problems will find this thread via Google.
