Other Parts Discussed in Thread: TLV9004
I am using op-amp LM224A of TI make and LM224D of ON-semi make in one of our ciruit. I have observed one weired behaviour which I am not able to understand.
Voltage Gain : 3.7
Voltage Input : Rectified DC inverted sine wave
With ON semi make Op-amp I observed after saturation op-amp peak start to clip off at 2.2V and on increasing the voltage at the input, the behaviour of the output used to reach towards a square wave. If voltage at input is increased further then output behaviour gets inverted and distorted and it comes out of saturation mode. Please refer the image for the same.
However with TI make the observation is : no matter of whatever is the input voltage once the reaches to saturation it gives perfectly square wave at extreme saturation.
kindly guide , which parameter is causing the output of op-amp in extreme saturation to get inverted and distorted.
