Microphone Preamplifier – Sound Sensor
This is an easy to construct dual-stage microphone pre-amplifier. The project can be used as a sound sensor or microphone pre-amplifier. The 1st op-amp pre-amplify the very low-level signal coming from the condenser microphone and 2nd op-amp provides more boost to the audio signal....

Low noise Mini Electret Microphone PreAmplifier
This single supply microphone pre-amplifier amplifies the output signal of an electret capsule microphone to audio line levels. An op-amp is used as a trans-impedance amplifier to convert the output current from the microphone into a signal-level voltage. The circuit works with 9V so...
