ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3V, OVDD = 2.5V, 0.1F and 1F capacitors from REFP, REFN, and COM to GND; REFOUT connected to REFIN through a
10kΩ resistor, VIN = 2Vp-p (differential w.r.t. COM), CL = 10pF at digital outputs (Note 1), fCLK = 20MHz, TA = TMIN to TMAX, unless
otherwise noted. Typical values are at TA = +25°C.) (Note 2)
