Square wave and triangle wave oscillator circuit composed of 5532

This article is a square wave and triangle wave oscillation circuit composed of 5532. The square wave and triangle wave oscillation circuit uses an operational amplifier to generate high-precision square waves and triangle waves. The output frequency is determined by the resistors R1, R2 and R3 and the capacitor C. The calculation formula is:

. The positive and negative power supply voltage required by the circuit can reach 22V. Although the output waveform amplitude is asymmetric, the square wave output can still maintain a 50% duty cycle.
