INA199: Is the Rshunt can be use together with other deivces?

Andy_Lin

Part Number: INA199

Hi Team,

My customer INA199 as solution in their application, and having a question regrading Rshunt,

their application having another load switch would also needed current sense which wanted to use the same Rshunt together with INA199,

is this Ok for this using case? If it's ok , does this will influence the sensing accuracy of the INA?

Andy,

How is the Rshunt actually shared? Is there a schematic you can share. Please take note to the IB is typically 28 µA and you can see the IB. Also see figure 8 in the datasheet.

Andy,

Yes we can connect the INA199 in parallel with another device as long as the routing is correct and any loading of the other device will not cause issues.
