illustrate

The LMV1090 is a fully analog dual differential input, differential output, microphone array amplifier designed to reduce background noise in voice communication applications while providing superior speech intelligibility.

The LMV1090 retains the near-field voice signal at 4 cm in the microphone while rejecting microphones with far-field noise exceeding 50 cm. Far-field rejection of up to 20dB is possible in a properly configured and 0.5dB matched microphone with ±.

Part of the family of PowerWise™ energy-saving solutions, the LMV1090 consumes only 600μA of supply current, delivering superior performance with DSP solutions that consume more than 10 times the power.

Dual microphone inputs and processed signal outputs to provide excellent poor immunity to interference. Microphones with internal low-noise bias supplies are biased.
