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 or better, if referenced to the two-tone envelope.
Note 3:
Digital outputs settle to V

. Parameter guaranteed by design.
Note 4:
With REFIN driven externally, REFP, COM, and REFN are left floating while powered down.
Note 5:
Equivalent dynamic performance is obtainable over full OV
