CD4093 sine wave switching to square wave circuit

Published:2011/6/9 21:19:00 Author:John | Keyword: sine wave, square wave | From:SeekIC

The input sine wave voltage supplies power to IC1 through the half-wave double voltage circuit, which is composed of C1, C2 and D1, D2. IC1A constitutes amplifier in order to amplify the input signal. The signal would be transformed into a square wave signal through the IC1B and IC1C. Then square wave signalis output after the amplification by IC1D, IC1E and IC1F. R2 is used to adjust the output signal amplitude. The circuit as shown can output square wave with good performance within the 20Hz-20KHz. During the application, the valid value for the input sine wave is suggested to be greater than 1.5 volts in order to ensure the quality of the output signal. Minimum input voltage sine wave must be greater than 750mV and the peak value for output signal is about 2 volts at this time. Figure 1 sine wave switching to square wave circuit
