(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions.
(2) All voltages are measured with respect to GND = 0V, unless otherwise specified.
Electrical Characteristics
Unless otherwise noted, these specifications apply for VDD=4.75V to 5.25V, REF=VDD, T_A=25°C. Boldface limits are over
the temperature range of −30°C ≤ T_A ≤ 85°C unless otherwise noted. DAC input code range 12 to 1012. DAC output
C_L = 200 pF unless otherwise noted.

(1) Device Specification is guaranteed by characterization and is not tested in production.
(2) DAC Offset is the y-intercept of the straight line defined by DAC output at code 0d12 and 0d1011points of the measured transfer
characteristic.
(3) DAC Gain Error is the difference in slope of the straight line defined by DAC output at code 0d12 and 0d1011 points of transfer
characteristic, and that of the ideal characteristic.
