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.
