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

Linearity
Absolute linearity⁽¹⁾.......................................... ±1.0 Ml⁽²⁾
Relative linearity⁽³⁾........................................... ±0.2 Ml⁽²⁾
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) 1 Ml = Minimum Increment = R_TOT/31.
(3) Relative linearity is a measure of the error in step size between taps = V_W(n+1) - [V_w(n) + Ml] = +0.2 Ml
