ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VDD = 3.3V; OVDD = 2V; 0.1µF and 1.0µF capacitors from REFP, REFN, and COM to GND, REFOUT connected to REFIN through a

10k

Ω resistor; VREFIN = 2.048V; VIN = 2VP-P (differential with respect to COM); CL = 10pF at digital outputs; fCLK = 120MHz; TA =

TMIN to TMAX, unless otherwise noted;

≥+25°C guaranteed by production test, <+25°C guaranteed by design and characterization;

typical values are at TA = +25°C.)

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.
