6.3.1 Basic Connections

Figure 6-1 shows the basic connections of the INA21x. Connect the input pins (IN+ and IN–) as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistor.

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.

On the RSW package options, two pins are provided for each input. Tie these pins together (that is, tie IN+ to IN+ and tie IN– to IN–).
