Web20 sept. 2024 · Electret microphone. The gain of this circuit can changed by replacing the 100K Ohm resistor with another value. When the value is 100K ohms, the gain is set at 100X, which is the highest gain the LM358 can produce. So that will make the microphone pretty sensitive. You can lower the gain by using a smaller resistor. purefield ingredients llcWebSPH0641LM4H-1). Such microphones are used in mobile devices, because they output digital data, are immune to interferences, allow for flexible topology and board layout, and they have low noise level and cost.
