8.2.1.2 Detailed Design Procedure

Figure 8-1 shows the basic connections of the INA300 device. The input terminals, IN+ and IN–, must be connected as closely as possible to the current-sensing resistor to minimize any resistance in series with the shunt resistance. Additional resistance between the current-sensing resistor and input terminals can result in errors in the measurement. When input current flows through this external input resistance, the voltage developed across the shunt resistor can differ from the voltage reaching the input terminals.
