Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = [V(RW(n)(actual)) - V(RW(n)(expected))]/MI
V(RW(n)(expected)) = n(V(RH) - V(RL))/99 + V(RL), with n from 0 to 99.
(2) Relative linearity is a measure of the error in step size between taps = [V(RW(n+1)) - (V(RW(n)) - MI)]/MI
(3) 1 Ml = Minimum Increment = [V(RH) - V(RL)]/99.
(4) Typical values are for TA = 25°C and nominal supply voltage.
(5) This parameter is not 100% tested.
(6) Ratiometric temperature coefficient = (V(RW)T1(n) - V(RW)T2(n))/[V(RW)T1(n)(T1 - T2) x 106], with T1 & T2 being 2 temperatures, and n
from 0 to 99.
(7) Measured with wiper at tap position 31, RL grounded, using test circuit.
