LMV1089 Far Field Noise Suppression Microphone Amplifier

LMV1089 Description

LMV1089 Dual Input, Clarisound™ Far Field Noise Suppression Microphone Amplifier with Automatic Calibration Capability October 24, 2008 LMV1089 Dual.
The LMV1089 is a fully analog dual differential input, differential output, microphone array amplifier designed to reduce background acoustic noise, w.

LMV1089 Features

* Low power consumption Shutdown function No added processing delay Differential outputs Automatic calibration Adjustable 6 - 48dB gain Excellent RF immunity Space-saving 36

LMV1089 Applications

* The LMV1089 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 calibrated system. Part of the Powerwise™ family of energy efficien
