TERMINOLOGY
Analog Bandwidth
The analog input frequency at which the spectral power of the
fundamental frequency (as determined by the FFT analysis) is
reduced by 3 dB.
Aperture Delay
The delay between a differential crossing of ENCODE and
ENCODE, and the instant at which the analog input is sampled.
Aperture Uncertainty (Jitter)
The sample-to-sample variation in aperture delay.
Differential Nonlinearity
The deviation of any code from an ideal 1 LSB step.
ENCODE Pulse Width/Duty Cycle
Pulse width high is the minimum amount of time that the
ENCODE pulse should be left in Logic 1 state to achieve rated
performance; pulse width low is the minimum time ENCODE
pulse should be left in low state. At a given clock rate, these
specs define an acceptable encode duty cycle.
Harmonic Distortion
The ratio of the rms signal amplitude to the rms value of the
worst harmonic component.
Integral Nonlinearity
The deviation of the transfer function from a reference line
measured in fractions of 1 LSB using a “best straight line”
determined by a least square curve fit.
Minimum Conversion Rate
The encode rate at which the SNR of the lowest analog signal
frequency drops by no more than 3 dB below the guaranteed
limit.
Maximum Conversion Rate
The encode rate at which parametric testing is performed,
above which converter performance can degrade.
Output Propagation Delay
The delay between a differential crossing of ENCODE and
ENCODE, and the time when all output data bits are within
valid logic levels.
Overvoltage Recovery Time
The amount of time required for the converter to recover to
0.02% accuracy after an analog input signal of the specified
percentage of full scale is reduced to midscale.
Power Supply Rejection Ratio
The ratio of a change in input offset voltage to a change in
power supply voltage.
Signal-to-Noise and Distortion (SINAD)
The ratio of the rms signal amplitude (set at 1 dB below full
scale) to the rms value of the sum of all other spectral compo-
nents, including harmonics but excluding dc. Can be reported
in dB (that is, relative to signal level) or in dBFS (always related
back to converter full scale).
Signal-to-Noise Ratio (Without Harmonics)
The ratio of the rms signal amplitude (set at 1 dB below full
scale) to the rms value of the sum of all other spectral compo-
nents, excluding the first five harmonics and dc. Can be
reported in dB (that is, relative to signal level) or in dBFS
(always related back to converter full scale).
Spurious-Free Dynamic Range
The ratio of the rms signal amplitude to the rms value of the
peak spurious spectral component. The peak spurious
component may or may not be a harmonic.
Transient Response
The time required for the converter to achieve 0.03% accuracy
when a one-half, full-scale step function is applied to the analog
input.
Two-Tone Intermodulation Distortion Rejection
The ratio of the rms value of either input tone to the rms value
of the worst third-order intermodulation product; reported in
dBFS.
