NOTE: (1) An asterisk (

) indicates same specifications as the ADS801U. (2) dBFS refers to dB below Full Scale. (3) Percentage accuracies are referred to the
internal A/D Full Scale Range of 4Vp-p. (4) IMD is referred to the larger of the two input signals. If referred to the peak envelope signal (
0dB), the intermodulation
products will be 7dB lower. (5) No “rollover” of bits.
