Basic Connections

Figure 45 shows the basic connections of the INA180. 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.

NOTE: For best measurement accuracy, connect analog-to-digital converter (ADC) reference or microcontroller ground as closely as possible to the INAx180 GND pin, and add an RC filter between the output of the INAx180 and the ADC. See Closed-Loop Analysis of Load-Induced Amplifier Stability Issues Using ZOUT for more details.

A power-supply bypass capacitor of at least 0.1 µF is required for proper operation. 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.
