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.

Notes: (1) Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = [VW(n) - (n*MI + VW(0))]/MI = ±1 MI
Maximum.
(2) 1 Ml = Minimum Increment = RTOT/31 for resistor mode or 1MI = [VW(31) - VW(0)]/31 for voltage divider mode.
(3) Relative linearity is a measure of the error in step size between taps = (VW(n+1) - VW(n) ] )/MI - 1= ±0.2 MI
