ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3V; OVDD = 2.7V; 0.1F and 1F capacitors from REFP, REFN, and COM to GND; VREFIN = 2.048V; REFOUT connected to
REFIN through a 10k
Ω resistor; VIN = 2VP-P (differential with respect to COM); CL = 10pF at digital outputs; fCLK = 40MHz; TA = TMIN
to TMAX, unless otherwise noted. ≥ +25°C guaranteed by production test, < +25°C guaranteed by design and characterization; typi-
cal values are at TA = +25°C.)
