Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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.
ELECTRICAL CHARACTERISTICS
(VDD = 3.0V, OVDD = 2.7V; 0.1µF and 1.0µF capacitors from REFP, REFN, and COM to GND; VREFIN = 2.048V, REFOUT connected
to REFIN through a 10k⦠resistor, VIN = 2Vp-p (differential with respect to COM), CL â 10pF at digital outputs, fCLK = 62.5MHz
(50% duty cycle), TA = TMIN to TMAX, unless otherwise noted. â¥+25°C guaranteed by production test, <+25°C guaranteed by design
and characterization.Typical values are at TA = +25°C.)
