Power Up and Down Requirements
The are no restrictions on the power-up or power-down conditions of V
CC
and the voltages applied to the potentiometer pins
provided that V
CC
is always more positive than or equal to V
H
, V

NOTES:
1. Absolute Linearity is utilized to determine actual wiper voltage versus expected voltage = (V
w(n)
(actual)–V
w(n)
(expected)) = ±1 Ml Maximum.
2. Relative Linearity is a measure of the error in step size between
taps = V
W
(n+1)
– [V
w(n)
+ Ml] = ±0.2 Ml.
3. 1 Ml = Minimum Increment = R
TOT
/31.
4. Typical values are for T
A
= +25°C and nominal supply voltage.
5. This parameter is periodically sampled and not 100% tested.
