APPLICATIONS INFORMATION
Output Filtering
The output voltage, VOUT, is simply IOUT ZOUT. This
makes ltering straightforward. Any circuit may be used
which generates the required ZOUT to get the desired lter
response. For example, a capacitor in parallel with ROUT
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 Sense Range
The inputs of the LTC6102 can function from V+ to (V+ – 2V).
Not only does this allow a wide VSENSE range, it also allows
the input reference to be separate from the positive supply
(Figure 6). Note that the difference between VBAT and V+
must be no more than the input sense voltage range listed
in the Electrical Characteristics table.
Monitoring Voltages Above V+ and Level Translation
The LTC6102 may be congured to monitor voltages that are
higher than its supply, provided that the negative terminal
of the input voltage is within the input sense range of the
LTC6102. Figure 7 illustrates a circuit in which the LTC6102
has its supply pin tied to the lower potential terminal of the
sense resistor instead of the higher potential terminal. The

operation of the LTC6102 is such that the –INS and –INF
pins will servo to within a few microvolts of +IN, which is
shorted to V+. Since the input sense range of the LTC6102
includes V+, the circuit will operate properly. The voltage
across RSENSE will be held across RIN by the LTC6102,
causing current VSENSE/RIN to ow to ROUT. In this case,
the supply current of the LTC6102 is also monitored, as
it ows through RSENSE.
Because the voltage across RSENSE is not restricted to
the sense range of the LTC6102 in this circuit, VSENSE
can be large compared to the allowed sense voltage. This
facilitates the sensing of very large voltages, provided
that RIN is chosen so that VSENSE/RIN does not exceed
