Description
BER
Bit Error Rate
Probability to exceed a specified error threshold for a sample. An error code is a code that
differs by more than ±4 LSB from the correct code
BW
Full-power Input
Bandwidth
The analog input frequency at which the fundamental component in the digitally
reconstructed output has fallen by 3 dB with respect to its low frequency value (determined
by FFT analysis) for input at full-scale
DG
Differential Gain
The peak gain variation (in percent) at five different DC levels for an AC signal of 20% full-
scale peak to peak amplitude. F
IN
= 5 MHz (TBC)
DNL
Differential Non-
linearity
The differential non-linearity for an output code (i) is the difference between the measured
step size of code (i) and the ideal LSB step size. DNL (i) is expressed in LSBs. DNL is the
maximum value of all DNL (i). DNL error specification of less than 1 LSB guarantees that
there are no missing output codes and that the transfer function is monotonic
DP
Differential Phase
The peak phase variation (in degrees) at five different DC levels for an AC signal of 20% full-
scale peak to peak amplitude. F
IN
= 5 MHz (TBC)
ENOB
Effective Number of
Bits
Where A is the actual input amplitude and V is the
full-scale range of the ADC under test
IMD
Inter Modulation
Distortion
The two tones intermodulation distortion (IMD) rejection is the ratio of either input tone to the
worst third order intermodulation products. The input tones levels are at - 7dB full-scale
INL
Integral Non-linearity
The integral non-linearity for an output code (i) is the difference between the measured input
voltage at which the transition occurs and the ideal value of this transition.
INL (i) is expressed in LSBs, and is the maximum value of all INL (i)
JITTER
Aperture Uncertainty
The sample to sample variation in aperture delay. The voltage error due to jitter depends on
the slew rate of the signal at the sampling point
NPR
Noise Power Ratio
The NPR is measured to characterize the ADC’s performance in response to broad
bandwidth signals. When using a notch-filtered broadband white-noise generator as the
input to the ADC under test, the Noise to Power Ratio is defined as the ratio of the average
out-of-notch to the average in-notch power spectral density magnitudes for the FFT
spectrum of the ADC output sample test.
(NRZ)
Non Return to Zero
When the input signal is larger than the upper bound of the ADC input range, the output code
is identical to the maximum code and the out-of-range bit is set to logic one. When the input
signal is smaller than the lower bound of the ADC input range, the output code is identical to
the minimum code, and the out-of-range bit is set to logic one (it is assumed that the input
signal amplitude remains within the absolute maximum ratings)
ORT
Overvoltage
Recovery Time
Time to recover 0.2% accuracy at the output, after a 150% full-scale step applied on the
input is reduced to midscale
PSRR
Power Supply
Rejection Ratio
PSRR is the ratio of input offset variation to a change in power supply voltage
SFDR
Spurious Free
Dynamic Range
The ratio expressed in dB of the RMS signal amplitude, set at 1 dB below full-scale, to the
RMS value of the next highest spectral component (peak spurious spectral component).
SFDR is the key parameter for selecting a converter to be used in a frequency domain
application (radar systems, digital receiver, network analyzer...). It may be reported in dBc
(i.e., degrades as signal level is lowered), or in dBFS (i.e. always related back to converter
full-scale)
