Preliminary Technical Data
Table 22. Programmable Slew Time values in seconds for a full scale change on any output range.
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 38, reducing the bandwidth and the rate of change of
the output current. These capacitors can be used as an
