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.

Key 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.
