DRIVING TYPE 1175 FLASH A/D LOADS
The circuits in Figures 6, 7, 8, 9, 10, 11 show a LM7131 in a
voltage follower configuration driving the passive equivalent
of a typical flash A/D input. Note that there is a slight ringing
on the output, which can affect accurate analog-to-digital
conversion. In these graphs, we have adjusted the ringing to
be a little larger than desirable in order to better show the
settling time. Most settling times at low gain are about 75 ns
to
<
1% of final voltage. The ringing can be reduced by add-
ing a low value (approximately 500
) feedback resistor from
the output to the inverting input and placing a small (pico-
farad range) capacitor across the feedback resistor. See Fig-
ure 9 and Figure 10 for schematics and respective perfor-
mance curves for flash A/D driving at A
V
= +5 with and
without a 2 pF feedback capacitor.
See section on feedback compensation. Ringing can also be
reduced by placing an isolation resistor between the output
and the analog-to-digital converter input— see sections on
driving capacitive loads and analog-to-digital converters.
Please refer to Figures 6, 7, 8, 9, 10, 11 for schematics of
test setups for driving flash A/D converters.
