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.

Simple Triangle to Sine Converters Wiring diagram Schematic
This is a simple Triangle-to-sine converters schema diagram, this schema conversion of triangle wave shapes to sinusoid is usually accomplished by diode-resistor shaping networks, which accurately reconstruct the sine wave segment by segment. Two simpler and less costly methods may be used to shape the triangle waveform of the 566 into a sinusoid with less than 2% distortion. The non-linear IDSVDS transfer characteristic of a P-channel junction FET is used to shape the triangle waveform.

The amplitude of the triangle waveform is critical and must be carefully adjusted to achieve a low distortion sinusoidal output. Naturally, where additional waveform accuracy is needed, the diode-resistor shaping scheme can be applied to the 566 with excellent results since it has very good output amplitude stability when operated from a regulated supply.
