TRIANGLE_WAVEFORM_GENERATOR

Published:2009/7/14 23:41:00 Author:Jessie | From:SeekIC

A low-frequency triangle-waveform generator is made from a single LM158 dual op amp and a few inexpensive components. The output frequency can be varied by changing the R5, Changing the value of C1, will shift the circuit's frequency range: Increasing the value will lower the oscillator's frequency and reducing the value will increase the frequency. Resistor R4 can be varied to change the output level. Powered from a 9-V supply, the circuit produces a 2-V p-p triangular output waveform.
