DEFINITIONS OF SPECIFICATIONS AND TERMINOLOGY
Integral Nonlinearity (INL)
Differential Nonlinearity (DNL)
Zero-Scale Error (EZS)
Gain Error (EG)
Signal-To-Noise Ratio + Distortion (SINAD)
Spurious Free Dynamic Range (SFDR)
Total Harmonic Distortion (THD)
SLAS190C – MARCH 1999 – REVISED SEPTEMBER 2006
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.
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 is defined as the deviation of the output from 0 V at a digital input value of 0.
Gain error is the error in slope of the DAC transfer function.
Signal-to-noise ratio + distortion 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 SINAD is
expressed in decibels.
Spurious free dynamic range is the difference between the rms value of the output signal and the rms value of
the spurious signal within a specified bandwidth. The value for SFDR is expressed in decibels.
Total harmonic distortion 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.
