Sine To Square Wave Converter Operational Amplifier Non-inverting

The purpose of this example is to showcase the outcome of the Operational Amplifier when the gain set exceeds the rail voltage. This circuit takes a sine wave and converts it into a square wave using a non-inverting amplifier configuration. Notice that when we increase the gain, the output starts to look more like a square wave. This is because the higher gains make the output go above the op-amp rail voltage, which is not possible, so it clips the signal. Although this example does convert a sine wave into a square wave, there are other ways to achieve this. This is not a good method because it causes the OP-Amp to go into saturation. A good example would be to use a Comparator, which is a rare case of using the Operational Amplifier in an open loop configuration.
