SiliconIntervention Announces Availability of Silicon-Based Fractal-D Audio Amplifier Evaluation Board

SiliconIntervention announced the availability of an evaluation board, demonstrating the high efficiency operation of its Fractal-D audio amplifier aimed at wearable applications such as earbuds and smart glasses as well as mobile products that demand extended battery life. SiliconIntervention is the company exploring a new type of bridge configuration that improves the efficiency at lower power levels while maximizing efficiency over a wide range of power levels.

Cloud2GND, an engineering house specializing in electronic circuit design, embedded systems, protocols, and connected devices developed the Bumblebee LE Audio Demonstrator, the first chipmaker-independent platform for product developers to test and evaluate Bluetooth LE Audio and Auracast applications. Featuring the Panasonic PAN1783 Bluetooth Low Energy 5.3 module, the board is a ready-to-use platform with a class-D amplifier, AKM stereo ADC/DAC, MEMS microphone, NFC and is powered over USB or external power supply.

Wireless communications company Rayson Technology has released a multiprotocol module based on Nordic Semiconductor’s nRF5340 System-on-Chip (SoC). The solution is designed for advanced Bluetooth LE Audio applications in consumer electronics as well as smart home. Measuring just 16.5 by 13.0 by 2.5mm, the BTM-N340X module supports LE Audio and its Low Complexity Communication Codec (LC3) for lower power wireless audio streaming applications.
