LMV1091: Far field noise reduction

TapasXplore

Part Number: LMV1091

Hi,

I am using a application in which I have to reduce ambient noise and want to capture the sound of interest. I am planning to use two microphones one to capture the ambient noise other to capture the signal of interest and noise. Then I am planning to subtract the two signal. I got to know there is dedicated IC for this application LMV1091. But it is not recommended for new design.

Do TI has similar IC or any other audio codec which provides similar function.

Hi José,

There is nothing that kind of sort available in the Microphone Preamplifier product folder.

Tapas,

Unfortunately, we don't have a direct replacement for this device. You must consider using another device that can gather your needs, although the new device could be more robust.
