INA293: bidirectional current sensing with two oppositely-connected amps

Part Number: INA293
Other Parts Discussed in Thread: INA240

Hi,

I need to sense current bidirectionally (in and out of a battery).  I had been planning to use the INA240 with it's reference pins biased to mid-supply, but I'm attracted to the INA293, which offers superior performance specs in nearly every respect - this is an amazing little part.  I get that the INA293 does not have reference pins accessible and is thus intended only for unidirectional current sensing, but I'm wondering if I could use two of these parts in my circuit with their input pins connected on opposite sides of my current shunt resistor.  They will see the same common-mode voltage (nominally 50V) and hopefully will respond in opposite directions depending on the sensed current direction.  This seems like it might work, but my one worry is that the input bias networks of the current-feedback amps might interact in a negative way if two are connected as I'm proposing.

I am aware of the overload condition mentioned in section 8.2.2.1 which explains that the amp needs recovery time proportional to negative Vsense.  I don't think this aspect of behavior will be a problem for me because I expect current to reverse direction rather slowly and infrequently, so I can afford to ignore the outputs the amp with the negative Vsense condition.

Thanks,

Josh
