Features for the TIDA-01470

  • Uses two PCM1864 4-channel audio ADCs to interface with four-microphone arrays to extract clear speaker voice from noisy environments
  • EnergySense notification for signal presence and loss that is a central part of a low-power, high-performance audio design

Description for the TIDA-01470

This easy-to-use reference design is for applications that are cost sensitive and require clear-spoken audio, such as voice triggering and speech recognition. This reference design uses a linear-microphone array (up to four) to capture a voice signal and convert it to a digital stream that can be used by a DSP system to extract clear audio from noisy environments.
