Looking for a broadband, high impedance op amp [Copy link]

I want to find an op amp with 100MHz bandwidth, 5V/us or higher slew rate, and 1G ohm input impedance. I searched a lot but none of them meet the requirements. Has anyone used an op amp that meets this requirement? Please recommend one

Generally, searching the official websites of big manufacturers such as ADI and TI will result in something like this AD8066, which should meet the requirements, 145MHZ bandwidth, 180V/us, 1000Gohm input impedance

Yes, the main parameters are OK, and I also found a group of components that meet the requirements on TI's official website. Thank you very much for your advice. I don't know much about ADI, so I'll study it.

"I searched a lot but none of them met the requirements." If the results found on the official websites of ADI and TI do not meet the requirements, it will be difficult to find ones that do meet the requirements.

Hahaha, great god, you came to my post again. I found the right one on TI. I didn't look in the right place before.
