DEFINITION OF SPECIFICATIONS
INTEGRAL NONLINEARITY ERROR (INL)
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 1/2 LSB
before the first code transition. “Positive full scale” is defined as
a level 1 1/2 LSB beyond the last code transition. The deviation
is measured from the middle of each particular code to the true
straight line.
DIFFERENTIAL NONLINEARITY ERROR (DNL)
In an ideal ADC, code transitions are 1 LSB apart. Differential
nonlinearity is the maximum deviation from this ideal value. It
is often specified in terms of resolution for which no missing
codes are guaranteed.
FULL-SCALE ERROR
The last + transition (from 011 . . . 10 to 011 . . . 11 for two’s
complement format) should occur for an analog voltage 1 1/2 LSB
below the nominal full scale (9.9995422 V for a
±10 V range).
The full-scale error is the deviation of the actual level of the last
transition from the ideal level.
BIPOLAR ZERO ERROR
Bipolar zero error is the difference between the ideal midscale
input voltage (0 V) and the actual voltage producing the
midscale output code.
UNIPOLAR ZERO ERROR
In unipolar mode, the first transition should occur at a level
1/2 LSB above analog ground. Unipolar zero error is the devia-
tion of the actual transition from that point.
SPURIOUS FREE DYNAMIC RANGE
The difference, in decibels (dB), between the rms amplitude of
the input signal and the peak spurious signal.
TOTAL HARMONIC DISTORTION (THD)
THD is the ratio of the rms sum of the first six harmonic com-
ponents to the rms value of a full-scale input signal and is
expressed in decibels.
SIGNAL TO (NOISE AND DISTORTION) (S/[N+D]) RATIO
S/(N+D) is the ratio of the rms value of the measured 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 decibels.
FULL POWER BANDWIDTH
The full power bandwidth is defined as the full-scale input fre-
quency at which the S/(N+D) degrades to 60 dB, 10 bits of
accuracy.
APERTURE DELAY
Aperture delay is a measure of the acquisition performance, and
is measured from the falling edge of the R/
C input to when the
input signal is held for a conversion.
TRANSIENT RESPONSE
The time required for the AD977/AD977A to achieve its rated
accuracy after a full-scale step function is applied to its input.
OVERVOLTAGE RECOVERY
The time required for the ADC to recover to full accuracy after
an analog input signal 150% of full-scale is reduced to 50% of
the full-scale value.
