NEW

Description

The AK5704 is a high performance analog front-end AD converter IC ideal for voice recognition, voice control, and conferencing applications. The device has a built-in 4-ch 32-bit ADC and a low noise microphone amplifier and extracts full performance of a high S/N microphone with low power consumption by achieving dynamic range of 105dB. It is possible to support up to 16-ch microphone array by connecting multiple AK5704’s. In addition, since it incorporates ultra-low power consumption voice activity detection, power consumption during wait time is greatly reduced .

Applications

  •                                 Ideal for voice recognition, voice control, and conferencing applications.
