Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1)
IDD is measured while continuously writing code 2048 to the DAC. For VIH < DVDD - 0.7 V and VIL > 0.7 V, supply current increases.
(2)
Power supply rejection ratio at full scale is measured by varying AVDD and is given by:
PSRR = 20 log [(EG(AVDDmax) - EG(AVDDmin))/VDDmax]
