Microphone Preamplifiers for Audio Applications

A microphone pre-amplifier boosts signals, typically to line-level (the level needed to transmit analog signals point-to-point, between devices.) Further amplification may be necessary. The noise performance of a pre-amp is critical since the final signal-to-noise ratio of downstream amplifiers can be magnified. For an audio input application, such as microphones, the pre-amp is physically mounted near the sensor that feeds it, to reduce noise and interference.  Learn More
