Description

The AK5704EN is a high performance analog front-end A / D converter IC ideal for voice recognition, voice control, and conferencing applications. The device has a built-in 4 channel 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 channel microphone array by connecting multiple AK5704EN’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.
