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. 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.
