AK5706 Overview
The AK5706 is a high-performance 24-bit stereo ADC (Analog-to-Digital 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,...
