*SNR/Harmonics based on an analog input voltage of –0.5 dBFS referenced to a 2 V full-scale input range. Harmonics are specified with the SFDR active
(SFDR = +5 V). SNR/SINAD specified with SFDR disabled (SFDR = Ground).
Specifications subject to change without notice.

NOTES
1Aperture uncertainty includes contribution of the AD9433, crystal clock reference, and encode drive circuit.
2tV and tPD are measured from the transition points of the ENCODE input to the 50%/50% levels of the digital output swing. The digital output load during testing is
not to exceed an ac load of 10 pF or a dc current of 50 µA. Rise and fall times measured from 10% to 90%.
Specifications subject to change without notice.
