definitions of specifications and terminology (continued)
total harmonic distortion (THD)
Total harmonic distortion is the ratio of the rms sum of the first six harmonic components to the rms value of the
measured input signal and is expressed as a percentage or in decibels.
spurious free dynamic range (SFDR)
Spurious free dynamic range is the difference in dB between the rms amplitude of the input signal and the peak
spurious signal.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
