COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; the functional operation of
the device (at these or any other conditions above
those listed in the operational sections of this specifi-
cation) is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect
device reliability.

Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = (V_H(n)(actual) - V_H(n)(expected)) = ±1 Ml
Maximum. n = 1 .. 29 only
(2) Relative linearity is a measure of the error in step size between taps = V_H(n+1) - [V_H(n) + Ml] = ±0.5 Ml, n = 1 .. 29 only.
(3) 1 Ml = Minimum Increment = R_TOT/31.
(4) Typical values are for T_A = 25°C and nominal supply voltage.
(5) This parameter only applies to a single potentiometer.
(6) This parameter is guaranteed by characterization.
(7) When performing multiple write operations, V_CC must not decrease by more than 150mV from its initial value.
