8.2 Typical Applications
The low input bias current of the INA190 allows accurate monitoring of small-value currents. To accurately
monitor currents in the microamp range, increase the value of the sense resistor to increase the sense voltage
so that the error introduced by the offset voltage is small. The circuit configuration for monitoring low-value
currents is shown in Figure 44. As a result of the differential input impedance of the INA190, limit the value of
RSENSE to 1 kΩ or less for best accuracy.
