Note 1: Absolute maximum ratings are those values beyond which the life
of a device may be impaired.
Note 2: Nonlinearity and monotonicity are defined and tested at VCC = 5V,
VREF = 4.096V, from code 20 to code 1023. See Rail-to-Rail output
considerations.
Note 3: Digital inputs at 0V or VCC.
Note 4: Load is 10kΩ in parallel with 100pF.
Note 5: VCC = VREF = 5V.
Note 6: Guaranteed by design and not subject to test.
Note 7: Measured at code 20.
Note 8: If a continuous clock is used, CS/LD timing (t7 and t9) will limit the
maximum clock frequency to 5MHz at 4.5V to 5.5V(3.85MHz at 2.7V to
5.5V).
Note 9: Any output shorted.
