Hi team,

My customer is using the TPS24711 and INA3221(amplifier) now. We are not sure about whether they can use the same resistor to sense the current as the structure below. Thanks.

Hi Frank,

Yes, the same current sense resistor can be used for TPS24711 and current sense amplifier.

The only thing is that the current sense amplifier should offer high impedance so that the error which is anyways offered by the INA device.
