Triangle Square Wave Generator Using Op Amp
The circuit shows a simple triangle and square wave generator with a common dual operational amplifier LM1558 to produce very low frequencies around 10 kHz. The time interval for one half cycle is about R * C and outs of supply of 10 mA. The amplitude of the triangle can be altered by adjusting the 47K and waveform offset can be eliminated by adding a capacitor in series with the output.
