be taken to limit the maximum output current by proper
choice of sense resistor and, if input fault conditions exist,
external clamps.
Output Filtering
The output voltage, V
OUT
, is simply I
OUT
Z
OUT
. This makes
filtering straightforward. Any circuit may be used which
generates the required Z
OUT
to get the desired filter
response. For example, a capacitor in parallel with R
OUT
will give a low pass response. This will reduce unwanted
noise from the output, and may also be useful as a charge
reservoir to keep the output steady while driving a switch-
ing circuit such as a mux or ADC. This output capacitor in
parallel with an output resistor will create a pole in the
output response at:

Input Common Mode Range
The inputs of the LTC6101 can function from 1.5V below
the positive supply to 0.5V above it. Not only does this

ence to be separate from the positive supply (Figure 5).
Note that the difference between V

and V

must be no
more than the common mode range listed in the Electrical
Characteristics table. If the maximum V
SENSE
is less than
500mV, the LTC6101 may monitor its own supply current,
as well as that of the load (Figure 6).
