Hi , I want to start here an open Diskussion which is the better OPV for the composite mode by using with LM3886
I can get both of the types for free. So we do not must diskuss about price and availability.
So only about technical Stuff , advantages, disadvantages.
And which OPV values in particular fit better with the LM3886 in 20k / 1k gain or 10k / 1k for the LM
So please diskuss here what are your opinions
Target Use: The Composite OPV for LM3886 at Vcc +/- 15V or 12V OPV Voltage.
kind regards and happy discussuing

exact OPV is one shortform in german of Operationsverstärker , otherwise , you see in the Type and Datasheet what is is 🙂
I've tried both. I find the LME49720/LM4562 to provide more consistent performance across a variety of loads. Also, the OPA1611 has a phase kink due to its internal compensation. That can wreak havoc on stability if you're not careful.
If you search a bit in the Chip Amps forum you'll find several examples of LM3886 composite amps. Why not build one of those?
