Simple Sine-Wave Generator Circuit


Posted on Aug 2, 2012

A 555 timer operating in the astable mode generates the driving pulses and two 4518 dual BCD (binary coded decimal) counters provide the square waves. A TL081 op amp serves as an output buffer-amplifier, and potentiometers Rl and R2 are used in order to control the pulse`s frequency and amplitude, respectively. The output-frequency range can be varied by changing Cx. For example, a value of 0.1 gives a range from about 0.1 to 30 Hz, and a value of 470 pF gives a range from about 10 Hz to 1.5 kHz.
