NOTE: (1) dBFS refers to dB below Full Scale. (2) Percentage accuracies are referred to the internal A/D Full Scale Range of 4Vp-p. (3) 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. (4) Based on (SINAD – 1.76)/6.02.
(5) No "rollover" of bits.
