7.3.1 Basic Connections

Figure 7-1 shows the basic connections for the INA199. The input pins, IN+ and IN–, must be connected as close 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, two pins are provided for each input. These pins must be tied together (that is, tie IN+ to IN+ and tie IN– to IN–).
