Description
General part information
LMV1091 Series
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.
