AD10201
DEFINITION OF TERMS
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 the 50% point on the rising edge of the ENCODE
command 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 Pulsewidth/Duty Cycle
Pulsewidth high is the minimum amount of time that the
ENCODE pulse should be left in logic “1” state to achieve rated
performance; pulsewidth 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.

Output Propagation Delay
The delay between the 50% point of the rising edge of ENCODE
command and the time when all output data bits are within valid
logic levels.
Power Supply Rejection Ratio
The ratio of a change in output 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 components,
excluding the first six harmonics and dc. [May be reported in dBc
(i.e., degrades as signal levels are lowered) 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 components,
excluding the first six harmonics and dc. [May be reported in
dBc (i.e., degrades as signal levels are lowered) 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. [May be reported in dBc (i.e., degrades
as signal levels is lowered) or in dBFS (always related back to
converter full-scale).]
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 dBc.
Voltage Standing Wave Ratio (VSWR)
The ratio of the amplitude of the electric field at a voltage maximum
to that at an adjacent voltage minimum.
