(1) The internal shunt resistor is intended to be used with the internal amplifier and is not intended to be used as a stand-alone resistor. See the Integrated Shunt Resistorsection for more information.
(2) See Maximum Continuous Currentfor additional information on the current derating and review layout recommendations to improve the current handling capability of the device at higher temperatures.
(3) System gain error includes amplifier gain error and the integrated sense resistor tolerance. System gain error does not include the stress related characteristics of the integrated sense resistor. These characteristics are described in the Shunt Resistor section of the Electrical Characteristicstable.
