High-Dynamic-Range, 16-Bit, 100Msps ADC with -82dBFS Noise Floor 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS (AVDD = AVDDA = 3.3V, DVDD = 1.8V, AGND = DGND = 0, internal reference, INP and INN driven differentially, CLKP and CLKN driven differentially, CL = 5pF at digital outputs (D0–D15, DOR), CL = 15pF for DAV, fCLK = 100MHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C, unless otherwise noted.) (Note 1) 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.
