NOTES:

1. OFFSET ERROR is the difference between the input voltage that causes the 00 to 01 output code transition and (VREF+ - VREF-)/128.

2. GAIN ERROR is the difference the input voltage that causes the 3F16 to overflow output code transition and (VREF+ - VREF-) x 127/128.

3. The total input voltage range, set by VREF+ and VREF-, may be in the range of 1 to (VDD + 1) V.

4. Parameter not tested, but guaranteed by design or characterization.
