Having been on the receiving end of designer queries from 1985 forward, there are some common oversights and misunderstandings that show up regularly. These essentially fall into three areas:

1. Not considering the actual operating voltage range on the I/O or internal pins of the device being used.
2. Misunderstanding the elements that contribute to an output dc offset or drift error.
3. Accidentally building an oscillator (or even worse, a nominally stable design that slips over into oscillation over production and/or temperature ranges).
