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.

output is unloaded. See Applications Information.

Note 6: Guaranteed by design. Not subject to test.

Note 7: Measured at code 50.
