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.
NOTE 1: All voltage values are with respect to VSS(DAC) for DAC channel measurements and VSS(ADC) for ADC
channel measurements.
