Differential Microphone Pre-Amplifier

https://www.electronics-lab.com/differential-microphone-pre-amplifier/

The project shown here is a microphone preamplifier that provides high quality amplification, optimized for use in computers, media and mobile applications. The pre-amplifier provides a differential input stage, making the device particularly effective when layout constraints force the microphone amplifier to be physically remote from the ECM microphone. This project features adjustable gain using […]
