LTC1658
ELECTRICAL CHARACTERISTICS
The
q
denotes specifications which apply over the full operating
temperature range.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
a device may be impaired.
Note 2:
Nonlinearity is defined from code 50 to code 16383 (full scale).
See Applications Information.
Note 3:
DAC switched between code 16383 and code 50.
Note 4:
Digital inputs at 0V or V
CC
.
Note 5:
V
OUT
can only swing from (GND +
V
OS
)
to (V
CC
–
V
OS
)
when
output is unloaded. See Applications Information.
Note 6:
Guaranteed by design. Not subject to test.
Note 7:
Measured at code 50.
