I want to make a circuit that I found. The circuit uses +/-12 V input to power some op-amps. I want to make the circuit work with a single 9 V battery. I've searched some rail splitter circuits and designed this:
It is based on this schematic:
My idea is to use cheap op-amps that I have like the TL07x.
I simulated this rail splitter connected to the circuit that I'm trying to power in LTspice and it works OK. This is the current on the buffer (U8) output:
From what I've read, the problem with rail splitters made with a buffer is the max. current they can handle. Is this max. current OK with the op-amps that I want to use? Is there another issue with this circuit that I have to know? Is there something I can change in the rail splitter circuit to make it work better?
The circuit that I need to power is simulated here.
