ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.3V, OVDD = 2.5V, 0.1µF and 2.2µF capacitors from REFP, REFN, and COM to GND; REFOUT connected to REFIN through a
10k
Ω resistor, VIN = 2VP-P (differential with respect to COM), CL = 10pF at digital outputs, fCLK = 100MHz, 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.)
