definitions of specifications and terminology
integral nonlinearity (INL)
The relative accuracy or integral nonlinearity (INL), sometimes referred to as linearity error, is the maximum
deviation of the output from the line between zero and full scale excluding the effects of zero code and full-scale
errors.
differential nonlinearity (DNL)
The differential nonlinearity (DNL), sometimes referred to as differential error, is the difference between the
measured and ideal 1 LSB amplitude change of any two adjacent codes. Monotonic means the output voltage
changes in the same direction (or remains constant) as a change in the digital input code.
zero-scale error (EZS)
Zero-scale error is defined as the deviation of the output from 0 V at a digital input value of 0.
gain error (EG)
Gain error is the error in slope of the DAC transfer function.
signal-to-noise ratio + distortion (S/N+D)
S/N+D is the ratio of the rms value of the output signal to the rms sum of all other spectral components below
the Nyquist frequency, including harmonics but excluding dc. The value for S/N+D is expressed in decibels.
spurious free dynamic range (SFDR)
SFDR is the difference between the rms value of the output signal and the rms value of the largest spurious
signal within a specified bandwidth. The value for SFDR is expressed in decibels.
total harmonic distortion (THD)
THD is the ratio of the rms sum of the first six harmonic components to the rms value of the fundamental signal
and is expressed in decibels.
