LMV1089 Dual Input, Clarisound™ Far Field Noise Suppression Microphone Amplifier with Automatic Calibration Capability October 24, 2008 LMV1089 Dual Input, Clarisound™ Far Field Noise Suppression Microphone Amplifier with Automatic Calibration Capability General Description The LMV1089 is a fully analog dual differential input, differential output, microphone array amplifier designed to reduce background acoustic noise, while delivering superb speech www.DataSheet4U.com clarity in voice communication 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.
