I would like to ask for help from all the seniors, is there any domestic operational amplifier that can replace the Texas Instruments OPA847IDBVR operational amplifier? Thank you very much!

OK, OK, thank you. I have one more question for you. Is there any good method or platform to check this kind of domestic substitute? I just started working and I am a newbie. Please help me. Thank you.

May I ask you, which company is this chip you are talking about from? I can't find it, sorry to take up your time, thank you

It is not easy to find, and it seems that there is none. Some domestic manufacturers also produce operational amplifiers, but there is still a certain gap in technical performance compared with OPA847IDBVR.

Indeed,....No, I searched for a long time and finally reported to the chief engineer. He also said to put it on hold for the time being, as it seems that there is really no one in the country that can meet the requirements.

No. Because if we want to do it, it will require a lot of cost investment, and it is obviously difficult to get a return on this investment.

It is normal that no one wants to do something that is difficult and thankless.

Some of Shengbangwei's op amps are good

It is not easy to find domestic components. You can either filter them roughly on the LiChuang Mall, and then go to the original manufacturer's official website to find the specific model and specification sheet for comparison. There is also a domestic component section in the forum, you can go and have a look

I just took a quick look at the specification. If you want to completely match the parameters, it is difficult to find domestic components.

Indeed, there are almost no domestically made products that meet the requirements. I have found similar domestically made components before, but I can't find out where they came from. They may be military components and are not available for purchase at all.
