The q denotes specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VCC = 5V (LTC1451LTC1452), VCC = 3V (LTC1453).

Note 3: Load is 5k

Ω in parallel with 100pF.

Note 4: DAC switched between all 1s and the code corresponding to VOS

for the part, i.e., LTC1451: code 18; LTC1453: code 30.

Note 5: Digital inputs at 0V or VCC.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of the device may be impaired.

Note 2: Nonlinearity is defined from the first code that is greater than or

equal to the maximum offset specification to code 4095 (full scale).
