Spurious-Free Dynamic Range (SFDR)

The ratio of the RMS value of the analog input sine wave

to the RMS value of the peak spur observed in the

frequency domain. It may be reported in dBc (that is, it

degrades as signal levels are lowered), or in dBFS (always

related back to converter full-scale). The peak spurious

component may or may not be a harmonic.

Temperature Drift

Temperature drift (for offset error and gain error) specifies

the maximum change from the initial temperature value to

the value at TMIN or TMAX.

Total Harmonic Distortion (THD)

THD is the ratio of the RMS signal amplitude of the input

sine wave to the RMS value of distortion appearing at

multiples (harmonics) of the input, typically given in dBc.

Two-Tone Intermodulation Distortion Rejection

The ratio of the RMS value of either input tone (f1, f2) to the

RMS value of the worst third-order intermodulation

product (2f1 − f2; 2f2 − f1). It is reported in dBc.
