6.4.4 Input Differential Overload

If the differential input voltage (VIN+ – VIN–) times gain plus the reference voltage exceeds the voltage swing specification, the INA185-Q1 drives the output as close as possible to the positive supply 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 INA185-Q1 returns to the expected value approximately 20µs after the fault condition is removed.
