RESISTOR SENSING APPLICATION
The voltage on the shunt resistor of the circuit below
is directly proportional to the current from the source.
Shunts developing 5 mV to 75 mV at I FS have been
used. Accuracy is enhanced at the higher voltage.
Select R T to be a 25.5 k ? 1% or better initial
tolerance resistor. This value will sink 1.5V /R T of
current from the VREF pin of the IR3720.
I L
R CS2 should be chosen such that this current through
it develops the same voltage that is developed by the
shunt at full scale current.
C CS2 is the integrator capacitor and should be
between 0.1 μ F and 10 μ F.
