Optimizing Dynamic Performance of the SMP04
Various operating parameters such as input voltage amplitude,
sampling pulsewidth and, as mentioned before, supply bypass-
ing and grounding all have an effect on the signal-to-noise ratio.
Table I shows the SNR versus input level for the SMP04.
Distortion of the SMP04 is reduced by increasing the supply
voltage. This has the effect of increasing the positive slew rate.
Table II shows data taken at 12.3 kHz sample rate and 2 kHz
input frequency. Total harmonic distortion is dominated by the
second and third harmonics.
FREQUENCY DOMAIN PERFORMANCE
The SMP04 has been characterized in the frequency domain for
those applications that require capture of dynamic signals. See
Figure 16a for typical 86.1 kHz sample rate and an 8 kHz input
signal. Typically, the SMP04 can sample at rates up to 85 kHz.
In addition to the maximum sample rate, a minimum sample
pulsewidth will also be acceptable for a given design. Our testing
shows a drop in performance as the sample pulsewidth becomes
less than 4
s.

86 kHz. Photo (a) Shows a 20 kHz Carrier Frequency and
Photo (b) Shows an 8 kHz Frequency.
Table III shows the effect of sampling pulsewidth on the SNR of
the SMP04. The recommended operating pulsewidth should be
a minimum of 5
s to achieve a good balance between acqui-
sition time and SNR for the 1.4 V p-p signal shown. For larger
swings the pulsewidth will need to be larger to account for
the time required for the signal to slew the additional voltage.
This could be used as a method of measuring acquisition
time indirectly.
