ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 2.7V to 5.5V, VOUT unloaded, REF ≤ VCC, TA = TMIN to TMAX
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: Nonlinearity is defined from code 20 to code 4095 (full scale). See
Applications Information.
Note 3: Load is 5kΩ in parallel with 100pF.
Note 4: DAC switched between all 1s and the code corresponding to VOS
for the part.
Note 5: Digital inputs at 0V or VCC.
Note 6: VOUT can only swing from (GND + |VOS|) to (VCC – |VOS|) when
output is unloaded.
Note 7: Guaranteed by design, not subject to test.
