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 defi ned from code 20 to code
1003 (full scale). See Applications Information.
Note 3: Digital inputs at 0V or V
CC
.
Note 4: Load is 10kΩ in parallel with 100pF.
Note 5: V
CC
= V
REF
= 5V. DAC switched between 0.1V
FS
and 0.9V
FS
, i.e.,
codes k = 102 and k = 922.
Note 6: All values are referenced to V
IH
and V
IL
levels.
Note 7: Guaranteed by design and not subject to test.
Note 8: The LTC1663E is guaranteed to meet performance specifi cations
from 0°C to 70°C. Specifi cations over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
The ● denotes specifi cations which apply over the full operating temperature
range, otherwise specifi cations are at T
A
= 25°C. V
CC
= 2.7V to 5.5V, V
CC
set as reference, V
OUT
unloaded, unless otherwise noted.
