Part Number: INA290 Tool/software: Hello,
We’d like to use this device to monitor the input current to a PCBA on a 48V line.
The INA290 will be powered off a 3.3V supply that comes up a few hundred milliseconds after the input supply voltage is…
Part Number: INA290 Tool/software: Dear Support,
I am planning to use INA290,
Can I input voltage to the IN+ pin with no power input to Vs? Is it OK if voltage is input to IN+ before Vs power is input, or if Vs is turned off while IN+ is input?
Thank…
Part Number: INA290 Tool/software: Dear Support I am considering using the INA290A3. I would like to eliminate as much current as possible flowing through the device during sleep (vs=0). Would putting an n-channel FET between the GND pin of the INA290 and…
Part Number: INA290 Tool/software: Hello,
In the INA290 Datasheet, the Vcm range is specified as Vs(V) ~ 120(V) as shown below.
If the INA290's Vs is supplied at 3.3V, then both +12V and +3.3V are within the current sense range, and if the INA290's…

Hi, I am using a INA290A3 to measure a 12V load using a 6mR shunt resistor.
I have an issue whereby the output read at the current net below has a positive offset that appears to increase with current.
It is out of spec for resistor…
Part Number: INA290-Q1 Other Parts Discussed in Thread: INA290 , INA293 , INA190 Hi,
We would like to use low side current measurement with INA290. I see many high side current measurement applications on datasheet but is there any problem about low side…

Hi, i am using INA290A3. Like typical circuit the following.
My circuit;
When Vin reaches about 0.7Vdc Vout goes 1Vdc. This situation does not occur below 0.7Vdc and above…
Part Number: INA290-Q1 Other Parts Discussed in Thread: INA290 , INA193 Hello,
My customer designed INA290 for DC/DC output voltage monitoring as shown below.
P15V_CS is output normally, but N15V_CS is not output normally.
N15V_CS should output 0.016ohm…
Part Number: INA290 Dear Support,
I have a question regarding the INA290A2 chip. I use this chip to measure maximum 3A. My problem is I get a fairly big difference between my multimeter current measurememt and my INA current measurement.To my 39 Ohm load…
