NOTES:
XDCP Timing
t
1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = [V(R
2. Relative linearity is a measure of the error in step size between taps = [V(R
3. 1 Ml = Minimum Increment = [V(R
4. Typical values are for T
5. This parameter is not 100% tested.
6. Ratiometric temperature coefficient = (V(R
