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

Datasheet Summary

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.

Features

Noise reduction without DSP-type artifacts.
Adapting AGC (Automatic Gain Control) on ambient noise.
level & downlink signal strength Downlink adjustable noise-reducing high pass filter Separate Uplink & Downlink Enable Functions No added process delays Low power consumption Shutdown function Maximum AGC Limiter Differential inputs & outputs for noise immunity Earpiece amplifier Available in a 25-bump micro SMD Key Specifications.

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.
