APPLICATIONS INFORMATION

GENERAL INFORMATION

The INA282 family voltage output current shunt monitors feature a common-mode range that extends 14V below

the negative supply rail, as well as up to 80V, which allows use for either low-side or high-side current sensing.

BASIC CONNECTIONS

Figure 32 shows the basic connection of an INA282 family device. The input pins, +IN and –IN, should be

connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt

resistance.

Figure 32. Typical Application

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.
