Input Differential Overload

If the differential input voltage (VIN+ – VIN–) times gain exceeds the voltage swing specification, the INA183 drives the output as close as possible to the IN+ pin or ground, and does not provide accurate measurement of the differential input voltage. If this input overload occurs during normal circuit operation, then reduce the value of the shunt resistor or use a lower-gain version with the chosen sense resistor to avoid this mode of operation. If a differential overload occurs in a fault event, then the output of the INA183 returns to the expected value approximately 30 µs after removal of the fault condition. When the input differential voltage is overloaded the bias currents will increase by a significant amount. The increase in bias currents will occur even with the device is powered down. Input differential overloads less than the absolute maximum voltage rating do not damage the device or result in an output inversion.
