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.
