LMV1099 Datasheet (National Semiconductor Corporation) - Uplink Far Field Noise Suppression & Downlink SNR Enhancing Microphone Amplifier

LMV1099, Uplink Far Field Noise Suppression & Downlink SNR Enhancing Microphone Amplifier

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
