ELECTRICAL CHARACTERISTICS
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: All voltages are with respect to GND.
Note 3: Linearity and monotonicity are defi ned from code k
where N is the resolution and k
limiting occurs. For V
defi ned from code 128 to code 65535. For V
and linearity is defi ned from code 8 to code 4095.
Note 4: Inferred from measurement at code 128 (LTC2655-16), or code 8
(LTC2655-12).
Note 5: DC Crosstalk is measured with V
reference, with the measured DAC at mid-scale.
Note 6: 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 specifi ed maximum operating junction temperature may impair
device reliability.

Note 7: Temperature coeffi cient is calculated by dividing the maximum
change in output voltage by the specifi ed temperature range. Maximum
temperature coeffi cient is guaranteed for C-grade only.
Note 8: Digital inputs at 0V or V
Note 9: Guaranteed by design and not production tested.
Note 10: 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 200pF to GND.
Note 11: V
reference mode. DAC is stepped ±1 LSB between half-scale and
half-scale – 1. Load is 2kΩ n parallel with 200pF to GND.
Note 12: DAC to DAC Crosstalk is the glitch that appears at the output
of one DAC due to a full scale change at the output of another DAC. It is
measured with V
DAC at mid-scale.
Note 13: C
Note 14: Gain error specifi cation may be degraded for reference input
voltages less than 1V. See Gain Error vs Reference Input Curve in the
Typical Performance Characteristics section.
