SAMPLE AND DIFFERENCE AMPLIFIER (Figure 23)
This circuit uses two sample-and-holds to measure the voltage
difference of a signal between two time points, t1 and t2. The
sampled voltages are fed into the differential inputs of the AMP02
instrumentation amplifier. A single resistor RG sets the gain of
this instrumentation amplifier. Using two channels of the
SMP04 in this application has the advantage of matched
sample-and-hold performance, since they are both on the same
chip.

AMPLIFIER (Figure 24)
This application again uses two channels of the SMP04 and an
instrumentation amplifier to provide a sampled difference signal.
The sample-and-hold signals in this circuit are tied together to
sample at the same point in time. The other two parts of the
SMP04 are used as amplifiers by grounding their control lines
so they are always sampling. One section is used to drive a
guard to the common-mode voltage and the other to generate a
+6 V reference to serve as an offset for single supply operation.
