The AFA offers the following additional features:
•
•
•
•
The ability to invert the signal by switching the positive
and negative inputs to the ladder network
The possibility of using DSX1 input as a second signal
input
Fully differential high-impedance inputs when both
preamplifiers are used with one DSX (the other DSX could
still be used alone)
Independent control of the DSX common-mode voltage

Under normal operating conditions, it is best to connect a
decoupling capacitor to VOCM, in which case, the common-
mode voltage of the DSX is half the supply voltage, which allows
for maximum signal swing. Nevertheless, the common-mode
voltage can be shifted up or down by directly applying a voltage
to VOCM. It can also be used as another signal input, the only
limitation being the rather low slew rate of the VOCM buffer.
If the dc level of the output signal is not critical, another coupling
capacitor is normally used at the output of the DSX; again, this
is done for level shifting and to eliminate any dc offsets contributed
by the DSX (see the AC Coupling section).
