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: Linearity and monotonicity are defined from code kL to code 2N–1,
where N is the resolution and kL is given by kL = 0.016 • (2N/ VFS), rounded
to the nearest whole code. For VFS = 2.5V and N = 12, kL = 26 and linearity
is defined from code 26 to code 4,095. For VFS = 4.096V and
N = 12, kL = 16 and linearity is defined from code 16 to code 4,095.
Note 3: Inferred from measurement at code 16 (LTC2630-12), code 4
(LTC2630-10) or code 1 (LTC2630-8).
Note 4: This IC includes current limiting that is intended to protect the
device during momentary overload conditions. Junction temperature can
exceed the rated maximum during current limiting. Continuous operation
above the specified maximum operating junction temperature may impair
device reliability.
Note 5: Digital inputs at 0V or VCC.
Note 6: Guaranteed by design and not production tested.
Note 7: Internal Reference mode. DAC is stepped 1/4 scale to 3/4 scale
and 3/4 scale to 1/4 scale. Load is 2kΩ in parallel with 100pF to GND.
Note 8: Temperature coefficient is calculated by dividing the maximum
change in output voltage by the specified temperature range.
