LMV1091 Dual Input, Far Field Noise Suppression Microphone Amplifier October 28, 2009 LMV1091 Dual Input, Far Field Noise Suppression Microphone Amplifier General Description The LMV1091 is a fully analog dual differential input, differential output, microphone array amplifier designed to reduce background acoustic noise, while delivering superb speech clarity in voice communication 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.
