Part Number: INA290
Other Parts Discussed in Thread: INA296A, , INA296B, INA293
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 0.9Vdc.
I would like to know your comment about this situation.
Vin;
Vout;
Hello Cenk,
There are a couple of issue here. The first major issue is the INA290 is only able to function with high VCM. Meaning the Vin must be greater than VCM = 2.7V. It may start working below this voltage but I would not recommend using it below this voltage. If you would like similar specifications with low VCM range please take a look at the INA293, INA296A, INA296B. Also please verify your schematic and actual circuit are the same as I assume the schematic has the IN+ and IN- pins reversed.
Regards,
Javier
