NOTES:

2. These parts are designed and adjusted for accuracy within the system tolerance given in the Electrical Specifications. The system tolerance

accounts for offsets in the differential and error amplifiers; reference-voltage inaccuracies; temperature drift; and the full DAC adjustment range.

3. VID input levels above 2.9V may produce an reference-voltage offset inaccuracy. Use a current limit resistor (10K) when pull up to 5V.
