ELECTRICAL CHARACTERISTICS (continued)
(VDD = +3V, OVDD = +2.5V, 0.1µF and 1.0µF 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 (Note 5), fCLK = 40MHz, TA = TMIN to
TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
