APPLICATIONS INFORMATION
Selection of External Input Resistor, RIN
RIN should be chosen to allow the required speed and
resolution while limiting the output current to 1mA. The
maximum value for RIN is 1k to maintain good loop sta-
bility. For a given VSENSE, larger values of RIN will lower
power dissipation in the LT6109 due to the reduction
in IOUT while smaller values of RIN will result in faster
response time due to the increase in IOUT. If low sense
currents must be resolved accurately in a system that has
a very wide dynamic range, a smaller RIN may be used
if the maximum IOUTA current is limited in another way,
such as with a Schottky diode across RSENSE (Figure 4).
This will reduce the high current measurement accuracy
by limiting the result, while increasing the low current
measurement resolution.
This approach can be helpful in cases where occasional
bursts of high currents can be ignored.
Care should be taken when designing the board layout for
RIN, especially for small RIN values. All trace and inter-
connect resistances will increase the effective RIN value,
causing a gain error.
The power dissipated in the sense resistor can cause a
significant thermal gradient and consequently a gain error
if RIN and ROUT are placed such that they can operate at
different temperatures. If significant power is being dis-
sipated in the sense resistor then care should be taken
