The current flowing across
the IS+ and IS– pins develops a differential voltage across the 0.4 mΩ shunt
and is amplified by the current shunt amplifier. The current flowing across
this integrated shunt is multiplied by the current gain of the INA254A1 (20
mV/A), INA254A2 (40 mV/A), or INA254A3 (75 mV/A). Do not use this integrated
shunt resistor as a stand-alone component. See the Integrated Shunt Resistor
section of the INA254 data sheet (
SLOS974) for more information.
