how convert sine to square

Hi.

What type of circuit could i use to convert a sine wave to a square wave. The resulting square wave would need to have the same frequency and amplitude of the sine wave. The sine wave would be working in the range of 0-10kHz and 0-2 V p-p. Could this be done using a 741 op-amp?


Any advice would be helpful.

Thanks.
 

OPAMP in comparator mode can be used for this purpose
 

elec_eng,
A comparator will provide a square wave of the same frequency, but the output amplitude would be a function of the comparator supply voltage, and would be independent of the amlitude of the sine wave input.
.
To provide amplitude control, you would need some kind of regulator. An analog multiplier could be used as the gain controller.
Regards,
Kral
