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: Nonlinearity and monotonicity are defined and tested at
VCC = 5V, VREF = 4.096V, from code 20 to code 1023. See the Rail-to-Rail
Output Considerations section.
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.
