Figure 7-4 shows a basic circuit connection for INA310x. The INA310x is configurable to allow for unidirectional high-side or low-side, current-sensing operation. The input pins (IN+ and IN–) must be connected as closely as possible with Kelvin connections to the shunt resistor to minimize any resistance in series with the shunt resistance. The Layout section provides the layout guidelines and a layout example.

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 V_S pin. The recommended value of a bypass capacitor is 0.01 μF
