产品概述
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 far-field
rejection is possible in a properly configured and using ±0.5dB matched micropohones.Part of the Powerwise™ family of energy efficient solutions, the LMV1091 consumes only
600μA of supply current providing superior performance over DSP solutions consuming greater than
ten times the power.The dual microphone inputs and the processed signal output are differential to provide
excellent noise immunity. The microphones are biased with an internal low-noise bias supply.
