CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.

NOTES:
4. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = [V(R

) = n(V(R

), with n from 0 to 99.
5. Relative linearity is a measure of the error in step size between taps = [V(R

)-(V(R
W(n)
) - MI)]/MI.
6. 1 Ml = Minimum Increment = [V(R
