LTC1655/LTC1655L
ELECTRICAL CHARACTERISTICS
The q denotes specifications which apply over the full operating temperature range, otherwise specifications are at T_A = 25°C.
V_CC = 4.5V to 5.5V (LTC1655), V_CC = 2.7V to 5.5V (LTC1655L); V_OUT unloaded, REF unloaded, unless otherwise noted.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Nonlinearity is defined from code 128 to code 65535 (full scale).
See Applications Information.
Note 3: DAC switched between all 1s and all 0s. V_FS = 4.096V.
Note 4: Digital inputs at 0V or V_CC.
Note 5: Part is clocked with pin toggling between 1s and 0s, CS/LD is low.
Note 6: Reference can be overdriven (see Applications Information).
Note 7: Guaranteed by design. Not subject to test.
Note 8: Guaranteed by correlation for other reference and supply
conditions.
