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.

Key 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-bump micro SMD package
