3 / 22 page  Dual, 8-Bit, 40Msps, 3V, Low-Power ADC with Internal Reference and Parallel Outputs _______________________________________________________________________________________ 3 ELECTRICAL CHARACTERISTICS (continued) (VDD = OVDD = 3V, 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 = 40MHz, TA = TMIN to TMAX, unless otherwise noted. ≥+25°C guaranteed by production test, <+25°C guaranteed by design and characerization. Typical values are at TA = +25°C.)
