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 4: Load is 10kΩ in parallel with 100pF.

codes k = 102 and k = 922.

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.
