Need help with noise on headphone amp! (op-amp issue?)

<< < (6/6)

tooki:
The NJR4556 works on as low as ±2V. So with your 9V supply, you can easily split it into ±4.5V and the opamp will be happy.

Look at the power supply section (bottom left) of this:

See how the ground there comes out the middle? Then the top rail is your +4.5V, the bottom is the -4.5V. Use those where your schematic calls for +9V/-9V.

It says 12V, but 9V will be fine for your opamp.

P.S. Please replace the embedded imgur images with images attached here. They're already broken.
