CAUTION: Stresses above those listed under âAbsolute Maximum Ratingsâ 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 specification) is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Capacitor Specifications VCC = +5V, TA = 25°C, single ended mode, CM = 0V, unless otherwise stated.

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 = CTOT/31.
(4) Typical values are for TA = 25°C and nominal supply voltage.
(5) This parameter is not 100% tested.
DC Electrical Specifications VCC = 5V, TA = 25°C unless otherwise specified.
