LMD18200 3A 55V H-Bridge

Posted on Feb 7, 2014

The LMV1090 is a fully Analog dual differential input, differ- ential output, Microphone array Amplifier designed to reduce background acoustic noise, while delivering superb speech clarity in voice Communication applications. The LMV1090 preserves near-field voice signals within 4cm of the Microphones while rejecting far-field acoustic noise grea

ter 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 LMV1090 consumes only 600 A of supply current pro- viding 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 mi- crophones are biased with an internal low-noise bias supply.
