Part Number: INA138 Other Parts Discussed in Thread: INA215 , INA293
Hi expert,
Do we have a INA138 pin to pin device that has higher accuracy?
Total current error requirement: <50mA
Power supply: 5V Vcc
Common mode voltage: > 20V
Sense current: …
Hello Grace,
Thanks for posting to the forum. Hope we can quickly help you.
It's hard to read what the shunt resistance is (R803) in your schematic, but the INA21x should be able to distinguish the current levels you want given the proper shunt resistance…
Hi Suyog,
The INA219 should not affect the operation of the DRV8840.
It may be difficult to identify zero current using a high side current shunt. This is because the current monitor will include all DRV8840, not just the load current.
The INA210 through…

I am trying to monitor High Side current using Rail to Rail Op-Amp. The ouput of that Opamp if interfaced with a microcontroller and applied RMS algorithm and…
Ivan,
The INA210 has a gain of 200, and the output is limited by the supply. See page 7 of the data sheet. Given that you can almost reach the rail of the supply on the output, you can back calculate the possible input. With the largest supply allowed…
Other Parts Discussed in Thread: INA213 Hi Team,
Please help us support our customer. In their evaluation, they were repeating ON/OFF the load with a hard switch and found that INA213 would go into abnormal mode. The device will continue drawing over 600mA…
We don't really have a recommendation for this as it varies according to desired application parameters and allowable tolerances. Also, we cannot guarantee any application design support we offer to not have any issues.
We would like to help you,…
