Almost every circuit I have looked (if not all of them) have their opamps powered with 4.5v by a voltage divider.
Is there a problem by powering the opamp with 9v?
I mean, for higher thresholds feedback loop diodes (like an LED) it would be better to have 9v on the opamp right? To achieve more "signal boost" and then reaching the led clipping.
Am I right or this does not work?
Thanks in advance,

The op amps ARE powered by 9volts.
The divider simply provides a mid-point reference, and allows the output voltage to swing around that point.
