ADP3339 minimum input power and tolerance

Peter,

  The only thing we guarantee are the mins and maxes in the spec table.  Looking at a few parts

on the bench at room temperature, from one date code and one wafer run, is very risky.

Even if it looks good, and you have had good luck in the past, the next batch of boards that

you build could have 50% failures with a different date code.  Additionally, we might do a fab

transfer or a mask set revision to increase yield and meet all of the numbers in the spec table

and maybe none of the parts would work in your system.  If this is a production design,

and you chose the wrong part, the only suggestion I have would be to do a board spin and

use the ADM7171 or ADM7154, both of which are less money than the ADP3339
