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.

CAPACITOR CHARACTERISTICS (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
