TIMING CHARACTERISTICS

Integral Nonlinearity (INL)

Differential Nonlinearity (DNL)

Source and Sink Current

Capability with VCC = 5V

Large-Signal Step Response

Midscale Glitch

Load Regulation vs Output Current

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 from code 20 to code

1003 (full scale). See Applications Information.

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: All values are referenced to VIH and VIL levels.

Note 7: Guaranteed by design and not subject to test.

Note 8: The LTC1663E is guaranteed to meet performance speciﬁcations

from 0°C to 70°C. Speciﬁcations over the –40°C to 85°C operating

temperature range are assured by design, characterization and correlation

with statistical process controls.

The

● denotes speciﬁcations which apply over the full operating temperature

range, otherwise speciﬁcations are at TA = 25°C. VCC = 2.7V to 5.5V, VCC set as reference, VOUT unloaded, unless otherwise noted.
