TIMING CHARACTERISTICS The ● denotes speciﬁcations which apply over the full operating temperature

range, otherwise speciﬁcations are TA = 25°C. VCC = 5V, VREF = 5V, fSCK = fSCK(MAX) as deﬁned in Recommended Operating Conditions,

unless otherwise noted.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: All voltage values are with respect to GND.

Note 3: Integral nonlinearity is deﬁned as deviation of a code from a

straight line passing through the actual endpoints of the transfer curve.

The deviation is measured from the center of the quantization band.

Note 4: Channel leakage current is measured while the part is in sample

mode.

Note 5: Guaranteed by design, not subject to test.
