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 used to determine actual capacitance versus expected capacitance = C_(n)(actual) — C_(n) (expected) = ±0.15 Ml.
(2) Relative linearity is a measure of the error in step size between settings = C_(n+1)—[C_(n) + Ml] = ±0.15 Ml.
(3) lsb = least significant bit = C_TOT/31.
(4) Typical values are for T_A = 25°C and nominal supply voltage.
(5) This parameter is not 100% tested
