com PRELIMINARY LMV1090 July 1, 2009 Dual Input, Far Field Noise Suppression Microphone Amplifier General Description The LMV1090 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 LMV1090 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.
