MEASURING CURRENT  
V–  
V+  
The INA117 can be used to measure a current by sensing the  
voltage drop across a series resistor, RS. Figure 4 shows the  
INA117 used to measure the supply currents of a device  
under test. The circuit in Figure 5 measures the output  
current of a power supply. If the power supply has a sense  
connection, it can be connected to the output side of RS to  
eliminate the voltage-drop error. Another common applica-  
tion is current-to-voltage conversion, as shown in Figure 6.
