Note 1: SNR, SINAD, THD, SFDR, and HD3 are based on an analog input voltage of -0.5dB FS referenced to a 1.024V full-scale
input voltage range.
Note 2: Intermodulation distortion is the total power of the intermodulation products relative to the individual carrier. This number is
6dB better if referenced to the two-tone envelope.
Note 3: Digital outputs settle to VIH,VIL.
Note 4: With REFIN driven externally, REFP, COM, and REFN are left floating while powered down.

ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.0V, OVDD = 2V, 0.1F and 1F capacitors from REFP, REFN, and COM to GND, VREFIN = 2.048V, REFOUT connected to
REFIN through a 10k resistor, VIN = 2VP-P (differential with respect to COM), CL = 10pF at digital outputs, fCLK = 83.3MHz, 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.)
