Low-Power 24-bit 2 ch ADC with Acoustic Activity Analyzer and Audio Buffer

NEW

Description

The AK5706 is a high-performance 24-bit stereo A / D converter with integrated Acoustic Activity Analyzer (AAA), audio buffer, and support for digital and high-SNR microphones. The AAA listens for audio activity in a very low-power state while the rest of the device remains powered off. Once qualifying audio content is detected, the audio buffer begins recording and the rest of the AK5706 wakes up, in turn waking other devices in the system as needed.  Designed for systems that must listen for specific types of audio activity while consuming very low power, the AK5706 is ideal for products such as speech recognition systems, security cameras, and smart doorbells.

Key Features

  • Acoustic Activity Analyzer listens for specific types of sounds, ignores others
    -As low as 30 μA power consumption while waiting for relevant audio
  • Audio buffer with up to 2s recording capacity
  • ADC: 24-bit/192 kHz, 105 dB SNR

Applications

  •                                 Ideal for security cameras, smart doorbells, smart watches, smart glasses, smart speakers, virtual reality (VR) and augmented reality (AR) applications.
