I was trying to obtain a square wave from a sine wave through a zero crossing detector using an op-amp with its high voltage gain and the inverting terminal grounded and the non-inverting terminal with the input the op-amp is driven to saturation and the output will be a square wave with amplitude equal to the supple voltages regardless what the input amplitude is , but thats what i m getting and i cant figure out why , anyone can help please ?
here are the output pictures at different input amplitudes with a 10KHz sine input.
+VCC = +5V
-VCC = -5V
@ input = 2V - 10Khz
@ input = 10V - 10Khz
