Timing Definitions
Sampling Delay,
is the time delay between the external
sample command (the rising edge of the clock) and the time
at which the analog input signal is actually sampled. This
delay is due to internal clock path propagation delays.
Data Latency,
after the analog sample is taken, the digital
representation is output on the digital data output bus after
the 3rd cycle of the clock. This is due to the pipeline nature
of the converter where the data has to ripple through the
stages. This delay is specified as the data latency. After the
data latency time, the data representing each succeeding
analog input sample is output on the following rising edge of
the clock pulse. The digital data output lags the analog input
sample by 3 sampling clock cycles.
Power-up Initialization,
this time is defined as the
maximum number of clock cycles that are required to
initialize the converter at power-up. The requirement arises
from the need to initialize some dynamic circuits within the
converter.
Static Performance Definitions
Differential Linearity Error, DNL,
is the worst case
deviation of a code width from the ideal value of 1 LSB. The
converter is guaranteed to have no missing codes over the
operating temperature range.
Integral Linearity Error, INL,
is the worst case deviation of
a code center from a best fit straight line calculated from the
measured data.
Dynamic Performance Definitions
Fast Fourier Transform (FFT) techniques are used to
evaluate the dynamic performance of the HI5710A. A low
distortion sine wave is applied to the input, it is sampled, and
the output is stored in RAM. The data is then transformed
into the frequency domain with a 2048 point FFT and ana-
lyzed to evaluate the dynamic performance of the A/D. The
analog sine wave input signal to the converter is -0.5dB
down from full scale for all these tests. The distortion num-
bers are quoted in dBc (decibels with respect to carrier) and
DO NOT
include any correction factors for normalizing to full
scale.
Signal-to-Noise Ratio, SNR,
is the measured RMS signal
to RMS noise for a specified analog input frequency and
sampling frequency. The noise is the RMS sum of all of the
spectral components excluding the fundamental and the first
five harmonics.
Signal-to-Noise + Distortion Ratio, SINAD,
is the measured
RMS signal to RMS sum of all other spectral components
below the Nyquist frequency excluding DC.
Effective Number Of Bits, ENOB,
the effective number of
bits (ENOB) is calculated from the measured SINAD data.
as follows:
ENOB = (SINAD - 1.76 + V
CORR
) / 6.02,
where: V
CORR
= 0.5dB.
V
CORR
adjusts the ENOB for the amount the analog input
signal is below full scale.
2nd and 3rd Harmonic Distortion,
is the ratio of the RMS
value of the 2nd and 3rd harmonic component, respectively,
to the RMS value of the measured input signal.
Analog Input Bandwidth,
is the frequency at which the
amplitude of the digitally
decreased 3dB below the amplitude of the input sine wave.
The input sine wave has a peak-to-peak amplitude equal to
the differential reference voltage. The bandwidth given is
measured at the specified sampling frequency.
