Selection of External Input Resistor, RIN
The external input resistor, RIN, controls the transconduc-
tance of the current sense circuit. Since IOUT = VSENSE/RIN,
transconductance gm = 1/RIN. For example, if RIN = 100,
then IOUT = VSENSE/100 or IOUT = 1mA for VSENSE = 100mV.
RIN should be chosen to allow the required resolution
while limiting the output current. At low supply voltage,
IOUT may be as much as 1mA. By setting RIN such that
the largest expected sense voltage gives IOUT = 1mA, then
the maximum output dynamic range is available. Output
dynamic range is limited by both the maximum allowed
output current and the maximum allowed output voltage, as
well as the minimum practical output signal. If less dynamic
range is required, then RIN can be increased accordingly,
reducing the max output current and power dissipation.
If low sense currents must be resolved accurately in a
system that has very wide dynamic range, a smaller RIN
than the max current spec allows may be used if the max
current is limited in another way, such as with a Schottky
diode across RSENSE (Figure 3a). This will reduce the high
current measurement accuracy by limiting the result, while
increasing the low current measurement resolution.

Figure 3a. Shunt Diode Limits Maximum Input Voltage to Allow
Better Low Input Resolution Without Overranging
This approach can be helpful in cases where occasional
large burst currents may be ignored. It can also be used
in a multirange conguration where a low current circuit
is added to a high current circuit (Figure 3b). Note that
a comparator (LTC1540) is used to select the range, and
transistor M1 limits the voltage across RSENSE LO.
Care should be taken when designing the board layout
for RIN, especially for small RIN values. All trace and inter-
connect impedances will increase the effective RIN value,
causing a gain error. In addition, internal device resistance
will add approximately 0.2Ω to RIN.
