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 Figure 2.
Note 3: Digital inputs at 0V or VCC.
Note 4: Load is 10kΩ in parallel with 100pF.
Note 5: VCC = VREF = 5V. DAC switched between 0.1VFS and 0.9VFS;
i.e., codes k = 102 and k = 922.
Note 6: Guaranteed by design, not subject to test.
Note 7: One DAC output loaded.
