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. High temperatures degrade operating lifetimes. Operating lifetime
is derated at temperatures greater than 105°C.
Note 4. Linearity and monotonicity are defined from code k

rounded to the nearest whole code. For V
linearity is defined from code 26 to code 4,095. For V
N = 12, k
Note 5. Inferred from measurement at code 16 (LTC2633-12), code 4
(LTC2633-10) or code 1 (LTC2633-8), and at full scale.
Note 6. This IC includes current limiting that is intended to protect the
device during momentary overload conditions. Junction temperature can
range, otherwise specifications are at T

Note 7. Digital inputs at 0V or V
Note 8. Guaranteed by design and not production tested.
Note 9. 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 10. Temperature coefficient is calculated by dividing the maximum
change in output voltage by the specified temperature range.
