Description

The “555” integrated circuit is a general-purpose timer useful for a variety of functions. In this 555 audio PWM project, we explore its use as an astable multivibrator. The ubiquitous 555 timer IC handles audio signals in its own pulse-width modulation (PWM) way. Here, the 555 IC works in astable mode. The switching frequency can be varied from 65 kHz to 188 kHz. Selection of PWM frequency depends on the amplitude of the input signal as well as the load impedance. By adjusting VR1, you can ensure comfortable listening with low audio distortion.
