Low Power Audio Amplifier


Posted on Feb 7, 2014

Another super-simple circuit. You could use this circuit to drive a low power speaker from a sound effects module or a noise generator. Or you could build your own amplified speakers for use with your computer. As shown (with no gain setting network between pins 1 and 8) the circuit amplifies the input signal by 20X. A gain of 200X can be obtained

by connecting a 10uF capacitor between pins 1 and 8. Connect a resistor in series with the 10uF capacitor for intermediate gain values. A 1. 2K series resistor, for example, results in a gain of 50X.
