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
Note 4: REFIN and REFOUT should be bypassed to GND with a 0.1µF (min) and 2.2µF (typ) capacitor.
Note 5: REFP, REFN, and COM should be bypassed to GND with a 0.1µF (min) and 2.2µF (typ) capacitor.
Note 6: Typical analog output current at f
Note 7: See Figure 3 for detailed system timing diagrams. Clock to data valid timing is measured from 50% of the clock
Note 8: Crosstalk rejection is tested by applying a test tone to one channel and holding the other channel at DC level.
Note 9: Amplitude matching is measured by applying the same signal to each channel and comparing the magnitude of the funda-
Note 10: Phase matching is measured by applying the same signal to each channel and comparing the phase of the fundamental
Note 11: SINAD settles to within 0.5dB of its typical value in unbuffered external reference mode.
