[AK5706] AK5706 Low-Power 2-ch ADC with AAA and Audio Buffer 1. General Description 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, in turn waking other devices in the system as needed. Designed for systems that must listen for specific Typ.es of audio activity while consuming very low power, the AK5706 is ideal for products such as speech recognition systems, security cameras, and smart doorbells. 2. Features 1.
