AKM Reveals Low-Power ADC Device With Acoustic Activity Sensor

Asahi Kasei Microdevices Corporation (AKM) has developed the AK5707, a low-power monaural 16-bit A/D converter (ADC) equipped with an Acoustic Activity Analyzer (AAA) and Audio Buffer for detection of specific sounds. The new compact ADC is useful for smart sensors that are able to detect glass breaking sounds or emergency alarms in multiple applications. The acoustic activity detect feature works at only 34μA, ideal for wearables.

Infineon Technologies introduced its battery-powered Smart Alarm System (SAS), a technology platform that achieves high accuracy and very low-power operation using sensor fusion based on artificial intelligence/machine learning (AI/ML). This technology combined with low-power wake-on acoustic event detection allows compact designs that exceed the detection accuracy of acoustic-only alarm systems used today.
