Hi Xu,
By all accounts the OPA4188 is an electrically superior replacement for the legacy LM224 ( I think you meant LM224, LM244 is a non-TI LED). However, because they are so different in design and electrical performances from each other that could…
If you need an ultra low input bias current, like max 4pA at 125C, LMC6484 is the only quad we may offer. If you may tolerate higher IB, we have several quads in smaller packages: closest LMP7704 in TSSOP package as well as OPA4191, OP4192, OPA4196,…
Hi Vladimir,
The OPA4196 precision quad op amp should do everything that you need. Here is a link to its datasheet:

It looks like it will do fine in your application. Let me know if you have any questions…
Hello Seung,
I believe Kai is right. The "Level 2" model just seems to have more information. I would purchase the typical TLC27M4 device, not a variant. So, that you would be a device that starts with "TLC27M4I" followed by the package designator…
Hi Rico,
Do expect that any op amp I suggest should be evaluated in your system to make sure it meets all the electrical performance requirements.
Since you require a quad op amp that can operate with +/-3.3 V supplies and fast overload recovery, there…
Hello Michael,
I searched the web for DIP adapters that would accommodate modern dual and quad SOIC packaged op amps. The LM3900N pin out is so unique I didn't find any DIP adapter that would work. I thought the old TI RC4136 quad op amp used the same…
