INA159: gain temperature drift & longevity

Mario Ming
Prodigy 30 points
Part Number: INA159
Other Parts Discussed in Thread: INA592

Tool/software:

Hello

1. I would like to know if there is any additional data available on gain temperature drift besides the typical 1ppm/°C. What is the maximum expected drift? Are there any trend graphs or distribution histograms regarding this topic?

2. This part is quite old already. Is there any information from TI regarding expected EOL?

Thank you.

    Hi Mario,

    1. Unfortunately, what is shown in the datasheet is all we have for the gain temperature drift. We can't guarantee a maximum expected drift since it's not in the datasheet. Sadly, I couldn't find any distribution histograms or graphs. We do have this information for its next generation part INA592 as shown below:

    2. As of now we are not expecting this part to EOL. 

    Best Regards,
