Low Power Audio Amplifier | ||
![]() 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. |
