Help! Search for BA715 IC OP-Amp(?) datasheet

[cocolino]

Anybody who has infos or even a full datasheet for this IC??

I searched google now for about an hour and all I came up with is that it seems to be a dual opamp. and ROHM (never heard this) is supposed to be the (or one of) manufacturer.

Any further kind of info regarding this part is highly appreciated!


It`s in a strange (to me) 9 pin plastic case that is called SIL-09 (or SIL-9) and looks like this:

Depending on what you need from the sheet, the NJM4558 comes close.

Here's a better and slightly more complete copy:

Cheap & easy replacement; find the quad version of your favourite, straighten the leads, cut off the surplus!

Thanks very much guys for Your all Your efforts!!🙂 🙂 😎

Well, then that`s an "ordinary" dual op-amp. as ordinary it can be. Good to know - I thought it maybe is something special.

Also I don`t need to replace (at least I think so) one of these BA715 (I just want to figure how the circuit works respectively what it is at all) I´ll keep this solution in mind - indeed very clever - and simple too! Thanks Arne!
