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 5k

Ω 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.
