Note 1: Equivalent dynamic performance is obtainable over full OV
Note 2: Specifications at ≥ +25°C are guaranteed by production test and < +25°C are guaranteed by design and characterization.
Note 3: SNR, SINAD, THD, SFDR, and HD3 are based on an analog input voltage of -0.5dBFS, referenced to a +1.024V full-scale
Note 4: Intermodulation distortion is the total power of the intermodulation products relative to the individual carrier. This number is
Note 5: Digital outputs settle to V
Note 6: With REFIN driven externally, REFP, COM, and REFN are left floating while powered down.
