_______________________________________________________________________________________
Note 1: Guaranteed by design. Not subject to production testing.
Note 2: Intermodulation distortion is the total power of the intermodulation products relative to the total input power.
Note 3: Analog attenuation is defined as the amount of attenuation of the fundamental bin from a converted FFT between two
applied input signals with the same magnitude (peak-to-peak) at fIN1 and fIN2.
Note 4: REFIN and REFOUT should be bypassed to GND with a 0.1F (min) and 2.2F (typ) capacitor.
Note 5: REFP, REFN, and COM should be bypassed to GND with a 0.1F (min) and 2.2F (typ) capacitor.
Note 6: Typical analog output current at fINA & B = 20MHz. For digital output currents vs. analog input frequency,
see Typical Operating Characteristics.
Note 7: See Figure 3 for detailed system timing diagrams. Clock to data valid timing is measured from 50% of the clock
level to 50% of the data output level.
Note 8: Crosstalk rejection is tested by applying a test tone to one channel and holding the other channel at DC level.
Crosstalk is measured by calculating the power ratio of the fundamental of each channel’s FFT.
Note 9: Amplitude matching is measured by applying the same signal to each channel and comparing the magnitude of the funda-
mental of the calculated FFT.
Note 10: Phase matching is measured by applying the same signal to each channel and comparing the phase of the fundamental
of the calculated FFT. The data from both ADC channels must be captured simultaneously during this test.
Note 11: SINAD settles to within 0.5dB of its typical value in unbuffered external reference mode.

ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.3V, OVDD = 2.5V, 0.1F and 2.2F capacitors from REFP, REFN, and COM to GND; REFOUT connected to REFIN through a
10k
resistor, VIN = 2VP-P (differential with respect to COM), CL = 10pF at digital outputs, fCLK = 100MHz, 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.)
