Description
General part information
LMV1089 Series
The LMV1089 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 LMV1089 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 calibrated system.
Part of the Powerwise™ family of energy efficient solutions, the LMV1089 consumes only 1.1mA of supply current providing superior performance over DSP solutions consuming greater than ten times the power.
