Typical Performance Characteristics
(Continued)
Specification Definitions
DIFFERENTIAL NON-LINEARITY (DNL)
is the measure of
the maximum deviation from the ideal step size of 1 LSB.
EFFECTIVE NUMBER OF BITS (ENOB, or EFFECTIVE
BITS)
is another method of specifying Signal-to-Noise and
Distortion Ratio, or SINAD. ENOB is defined as (SINAD -
1.76) / 6.02.
FULL POWER BANDWIDTH
is a measure of the frequency
at which the reconstructed output fundamental drops 3 dB
below its low frequency value for a full scale input. The test
is performed with f
IN
equal to 100 KHz plus integer multiples
of f
CLK
. The input frequency at which the output is 3 dB
relative to the low frequency input signal is the full power
bandwidth.
FULL SCALE ERROR
is the difference between the input
voltage just causing a transition to positive full scale and
V
REF
-1.5 LSB.
INTEGRAL NON-LINEARITY (INL)
is a measure of the de-
viation of each individual code from a line drawn from nega-
tive full scale (
1
2
LSB below the first code transition) through
positive full scale (1
1
2
LSB above the last code transition).
The deviation of any given code from this straight line is
measured from the center of that code value.
INTERMODULATION DISTORTION (IMD)
is the creation of
additional spectral components as a result of two sinusoidal
frequencies being applied to theADC input at the same time.
It is defined as the ratio of the power in the intermodulation
products to the total power in the original frequencies. IMD is
usually expressed in dB.
PIPELINE DELAY (LATENCY)
is the number of clock cycles
between initiation of conversion and the availability of that
conversion result at the output. New data is available at ev-
ery clock cycle, but the data lags the conversion by the pipe-
line delay.
SIGNAL TO NOISE PLUS DISTORTION (S/(N+D) or SI-
NAD)
is the ratio expressed in dB, of the rms value of the in-
put signal to the rms value of all of the other spectral compo-
nents below half the clock frequency, including harmonics
but excluding dc.
SIGNAL TO NOISE RATIO (SNR)
is the ratio of the rms
value of the input signal to the rms value of the other spectral
components below one-half the sampling frequency, not in-
cluding harmonics or dc.
SPURIOUS FREE DYNAMIC RANGE (SFDR)
is the differ-
ence, expressed in dB, between the rms values of the input
signal and the peak spurious signal, where a spurious signal
is any signal present in the output spectrum that is not
present at the input.
TOTAL HARMONIC DISTORTION (THD)
is the ratio of the
rms total of the first six harmonic components, to the rms
value of the input signal.
