Intelligent Wakeup for Voice Products
AKM's ultra low-power AK5706 listens for specific types of audio activity, performing analog acoustic analysis for onlyafew micro-amps of current while the rest of your system sleeps. Onece it's heard something that fits your criteria, it begins recording to its integrated audio buffer and wakes the rest of your system - you've saved aton of battery and captured the entire audio event.
The AK5706 combines intelligent wake-up with a high-quality ADC and support for both analog and digital microphones.
