General Description

The LMV1099 is an uplink and downlink voice intelligibility enhancing analog IC, ideally suited for mobile handsets.

Uplink voice intelligibility is improved by rejecting far-field noise through a unique two-microphone solution.

Downlink voice intelligibility is improved by enhancing the SNR (Signal-toNoise Ratio) between the downlink voice and the ambient noise environment at the user’s earpiece.
