APPLICATIONS INFORMATION
power dissipation is 41mW. This amount of power dis-
sipation will result in a 10°C rise in junction temperature
above the ambient temperature.
It is important to note that the LT6106 has been designed
to provide at least 1mA to the output when required, and
can deliver more depending on the conditions. Care must
be taken to limit the maximum output current by proper
choice of sense resistor and RIN– and, if input fault con-
ditions exist, external clamps.
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 re-
sponse. For example, a capacitor in parallel with ROUT
will give a lowpass 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:

Power Supply Connection
For normal operation, the V+ pin should be connected to
either side of the sense resistor. Either connection will
meet the constraint that +IN ≤ V+ and –IN ≤ V+. During
normal operation, VSENSE should not exceed 500mV (see
VSENSE(MAX) under Electrical Characteristics). This ad-
ditional constraint can be stated as V+ – (+IN) ≤ 500mV.
Referring to Figure 5, feedback will force the voltages
at the inputs –IN and +IN to be equal to (VS – VSENSE).
Connecting V+ to the load side of the shunt results in equal
voltages at +IN, –IN and V+. Connecting V+ to the supply
end of the shunt results in the voltages at +IN and –IN to
be VSENSE below V+.
If the V+ pin is connected to the supply side of the shunt
resistor the supply current drawn by the LT6106 is not
included in the monitored current. If the V+ pin is con-
nected to the load side of the shunt resistor (Figure 5),
the supply current drawn by the LT6106 is included in
the monitored current. It should be noted that in either
conguration, the output current of the LT6106 will not
be monitored since it is drawn through the RIN resistor
connected to the positive side of the shunt. Contract the
factory for operation of the LT6106 with a V+ outside of
the recommended operating range.

Reverse Supply Protection
Some applications may be tested with reverse-polarity
supplies due to an expectation of the type of fault during
operation. The LT6106 is not protected internally from ex-
ternal reversal of supply polarity. To prevent damage that
may occur during this condition, a Schottky diode should
be added in series with V– (Figure 6). This will limit the
reverse current through the LT6106. Note that this diode
will limit the low voltage performance of the LT6106 by
effectively reducing the supply voltage to the part by VD.
