PRODUCTION DATA
Figure 9-1 shows the basic connections for the INA183. 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.
A power-supply bypass capacitor is required on the IN+ pin. 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.
In server applications, the INA183 typically monitors the current on the 12-V bus that is distributed to various server sub-systems like memory, storage, or CPU power. The monitored current can be used by the server for fault detection or sub-system power optimization.
