Hi all:-

What would the consequences be of going to 20K on the midrange 10-bit A/D
input? I've read the reference manual and the data sheet. If the input is
bypassed with a 0.1uF or something of that ilk, it seems to be primarily
limited by the worst case leakage current on the input vs. guaranteed
accuracy. I'm willing to lose 1 bit or 1.5 bits in the A/D, and high
temperature operation is not required.

Any thoughts on this?

I'd normally put an op-amp in there without much thought, but the quantities
are such that thought will be well rewarded if a few cents can be snipped.

Thanks for any comments & Best regards,
