DataSheet.in LMV1099 Uplink Far Field Noise Suppression & Downlink SNR Enhancing Microphone Amplifier with Earpiece Driver August 12, 2010 LMV1099 Uplink Far Field Noise Suppression & Downlink SNR Enhancing Microphone Amplifier with Earpiece Driver 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. The LMV1099 preserves...
