Description: Far Field Noise Suppression Microphone Amplifier

Features

* No loss of voice intelligibility Low power consumption Shutdown function No added processing delay Differential outputs Adjustable 12 - 54dB gain Excellent RF immunity Available in a 25

Applications

* The LMV1091 preserves near-field voice signals within 4cm of the microphones while rejecting far-field acoustic noise greater than 50cm from the microphones. Up to 20dB of farfield rejection is possible in a properly configured and using ±0.5dB matched micropohones. Part of the Powerwise™ family of
