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 99, RL grounded, using test circuit.
