555 Amplifier Circuit Diagram. Circuit description and working audio amplifier circuit using 555 ic as its name suggest audio amplifier circuit using 555 ic shown in figure 1 is built around 555 ic with some other component like audio transformer resistor capacitor etc. This can drive a small loud speaker.

The above high frequency triangle waves are compared with the music input applied at the control input pin5 of the ic. Control pin 5 of 555 has been used here which is generally kept grounded through 01uf capacitor. Here the circuit designing is a simple process involving just two steps designing the preamplifier section and designing the astable multivibrator section.

This can drive a small loud speaker.

Circuit description and working audio amplifier circuit using 555 ic as its name suggest audio amplifier circuit using 555 ic shown in figure 1 is built around 555 ic with some other component like audio transformer resistor capacitor etc. Ne555 is a very popular ic among electronics hobbyists and students. Because by using this ic they build wide variety of electronic projects like audio projects led projects etc. Low power audio amplifier using 555 timer.
