The supply decoupling and Vcm decoupling is the same used as
for the standard ISL55210 evaluation board except R12 is
reduced from 200Ω to 20Ω to reduce noise into the Vcm
reference path. The optional elements (green) not populated in
the board as delivered include:
All of the signal path capacitors are set to pass the lowest
intended frequencies and were set to 10nF values in the board as
delivered. Figure 5 shows the populated board as delivered.
1. Two capacitors on the inverting summing junctions (C5 and
2. The 2 lower output networks are not fully populated. The
3. To select either of these alternate output paths, populate the
C6). These can be used to peak the response at higher gains
to hold flatness to higher frequencies but will be peaking the
output noise.
ADT1-1WT path is intended for distortion measurements
where the values shown would be a 200Ω load at the FDA
outputs but 50Ω source to the spectrum analyzer. This is
intended to emulate the lighter load of a typical ADC interface
circuit. To use this path, the output SMA needs to be removed
and reversed to pick up this output path on the lower side of
the board. The lowest optional output interface would be used
to measure the response to the FDA output pins when a 4 port
network analyzer is available.
connecting resistors for only one path at a time.
