ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(AVDD = DVDD = 4.75V to 5.25V, external reference VREF = 4.096V, fCLK = 3.6MHz (50% duty cycle), TA = -40°C to +85°C, unless
otherwise noted. Typical values are at AVDD = DVDD = 5V, TA = +25°C. Outputs are unloaded, unless otherwise noted.)
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 in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
