7.3.1 Basic Connections

Figure 7-3 shows the basic connections of the INA203, INA204, and INA205. The input pins, VIN+ and VIN–, should be connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance.

Power-supply bypass capacitors are required for stability. Applications with noisy or high-impedance power supplies may require additional decoupling capacitors to reject power-supply noise. Connect bypass capacitors close to the device pins.
