Hello everyone!
Attached is a schematics for inverted LM3886 that uses NE5532 opamp as a buffer and also as a difference amp for the balanced input signals. I am not in a hurry to build this one as it will probably take some time before LM3886 will be back in stock on Mouser.
This schematics is just hypothetical idea on how to combine multiple useful properties of opamps. There are a lot of benefits with inverted LM3886. An input opamp serves dual purpose too that I thought was really cool.
My other way of thinking was to not do balanced input and feed the signal into the inverted input of the NE5532 - in that case both chips will be inverting the signal and it will be in phase on the output. Idk though, is it that important to get output signal that is in phase? img attached
Any thoughts or input will be greatly appreciated.
