TERMINOLOGY
Integral Nonlinearity Error (INL)
Rev. 0 | Page 8 of 16
Linearity error refers to the deviation of each individual code
from a line drawn from negative full scale through positive full
scale. The point used as negative full scale occurs LSB before
the first code transition. Positive full scale is defined as a level
1 LSB beyond the last code transition. The deviation is
measured from the middle of each code to the true straight line
(see Figure 21).
Differential Nonlinearity Error (DNL)
In an ideal ADC, code transitions are 1 LSB apart. DNL is the
maximum deviation from this ideal value. It is often specified in
terms of resolution for which no missing codes are guaranteed.
Zero Error
Zero error is the difference between the ideal midscale voltage,
i.e., 0 V, and the actual voltage producing the midscale output
code, i.e., 0 LSB.
Gain Error
The first transition (from 100 . . . 00 to 100 . . . 01) should occur
at a level LSB above the nominal negative full scale
(4.999924 V for the ±5 V range). The last transition (from
011…10 to 011…11) should occur for an analog voltage
1 LSB below the nominal full scale (4.999771 V for the ±5 V
range.) The gain error is the deviation of the difference between
the actual level of the last transition and the actual level of the
first transition from the difference between the idea levels.
Spurious-Free Dynamic Range (SFDR)
SFDR is the difference, in decibels (dB), between the rms
amplitude of the input signal and the peak spurious signal.
Effective Number of Bits (ENOB)
ENOB is a measurement of the resolution with a sine wave
input. It is related to S/(N+D) by the following formula

and is expressed in bits.
Total Harmonic Distortion (THD)
THD is the ratio of the rms sum of the first five harmonic
components to the rms value of a full-scale input signal and is
expressed in dB.
Signal-to-Noise Ratio (SNR)
SNR is the ratio of the rms value of the actual input signal to the
rms sum of all other spectral components below the Nyquist
frequency, excluding harmonics and dc. The value for SNR is
expressed in dB.
Signal-to-(Noise + Distortion) Ratio (S/[N+D])
S/(N+D) is the ratio of the rms value of the actual input 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 dB.
Aperture Delay
Aperture delay is a measure of the acquisition performance and
is the time between the falling edge of the CS input and when
the input signal is held for a conversion.
Transient Response
Transient response is the time required for the ADC to
accurately acquire its input after a full-scale step function
was applied.
