1. All grades are monotonic to 12 bits over temperature.
2. Using internal feedback resistor.
3. Guaranteed by design and not tested.
4. Applies to IOUT; all digital inputs = VIL, VREF = 10V; specification also applied for IOUT2 when all digital inputs = VIH.
5. VREF = 10V, all digital inputs = 0V.
