I'm trying to make a square wave generator with an adjustable range of output signal amplitude (between 0 and 5V) using an LM741 op-amp and the following circuit:
The thing is, VOUT is limited by the saturation voltage which in this chase is +-15V but from what I understand it can be varied with a voltage divider formed by R1,R2 in regular inverting amplifier circuits. In my case, R1 and R2 (alongside τ=RC) only help adjust the output frequency with the formula for the period T=2RC*ln(1+β/1-β,), my output amplitude still being stuck between ≈+-VCC.
Edit with exactly what I need: I want that my peak-to-peak amplitude to be adjustable, not stuck between ≈+-VCC. For example, with a potentiometer, voltage divider or anything to make amplitude in the range of 0-5V. I can't find a way to make it adjustable.
