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

LMV1090 retains a near-field voice signal of 4 cm from 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 used microphone ± 0.5 dB matched.

ThePowerWise™ Energy Saving Solution is part of the family, LMV1090 DSP solutions that consume only 600μA of supply current and consume more than 10 times the power to deliver superior performance.

Dual microphone inputs and processed signal outputs to provide superior immunity to poor interference. The microphones of the internal low-noise bias power supply are biased.

Key specifications:

Far-field noise suppression electrons*	34 dB (typical)
SNRI E	26 dB (typical)
Supply current	600μA (typical)
Standby current	0.1μA (typical)
Signal-to-noise ratio (language audio band)	65 dB (typical)
Total harmonic distortion + noise	0.1% (typical)
PSRR (at 217Hz)	99 dB (typical)

* FFNS E at f = 1kHz
