Hello, Can i apply high voltage eg 40V to VBUS, V+ and V- pins while leaving the INA219 unpowered Vs=0V? Thanks.
Part Number: INA2290 Other Parts Discussed in Thread: INA229 Can we add a resistor (1K) between the V source and the Vbus input of the INA229. The input impedance is 1M, and 1K would be 0.1% of the input impedance. Will this significantly impact the performance…
Part Number: INA2290 Hi,
Good Day. I am in the datasheet of INA2290 ( https://www.ti.com/lit/ds/symlink/ina2290.pdf ), page 3 and page 24. The pin-out of the device are not the same for the DGK Package 8-Pin VSSOP Top View. Which one is the right one? Please…
Part Number: INA2290 Other Parts Discussed in Thread: INA229 Hi E2E, Our customer would like to measure battery voltage for automobile applications by reading bus voltage in charge monitor. How to use the INA229 device for voltage measurement? Regards, C…
Part Number: INA2290 Other Parts Discussed in Thread: INA240 , Hi ,
Is it possible to measure bidirectionnal current with below schematic having Rsense connected to J1/J2 to measure current from source to load and vice versa? If not do we offer another…
Ryan,
I would go through the parametric search as it also has cost as a filter/sort.

Hello Jordan,
I would like to suggest the INA2290. The max error is 0.1%. This does not guarantee that the gain error will match to the level you need, but I think this will help. Also the max VCM on this device is 120V.
Thanks for the prompt response Carolus!
When you said INA229, are you referring to INA229-Q1 or INA2290?
I think INA229-Q1 is not yet fully released.
Thanks to confirm!
