I
Two capacitors may be placed between the pins CAP1, CAP2
and AV
These two pins are only available on the LFCSP package. The
capacitors form a filter on the current output circuitry as shown
in Figure 63 reducing the bandwidth and the rate of change of
the output current. These capacitors can be used as an
