Top best answers to the question «How to convert sine wave into square wave»
Connect the Op amp +Vcc pin to your +voltage and the - ground pin to your - Vcc (that's the important bit) . Then connect your negative (or positive) between 10k resistors going from +Vcc to -Vcc and feed the input into the other Op amp input and you should get a square wave that you want .
- The sinewave must first be converted into a square-wave by amplifying it a lot and letting the amplifier clip the signal into square-waves. A small sine-wave will also clip the same as a large sine-wave so the amplitude of the sine-wave doesn't matter (as long as it is high enough for the amplifier to clip.
