NOTE: (1) dBFS refers to dB below Full Scale. (2) Percentage accuracies are referred to the internal A/D Converter 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.
