Developing a Voice-Controlled Bluetooth Speaker Based on the LC823455
As the demand for low-power portable audio devices increases, so does the need for cost-effective and energy-efficient system-level components. Today's audio solutions allow users to stream music on demand via a Bluetooth connection between external speakers and the streaming device, such as a smartphone.
ON Semiconductor, a leading semiconductor component manufacturer, provides several products designed for portable audio devices. Some products include the LC823455, a low−power, highly integrated audio processing SoC with energy-efficient DSP for audio and dual Arm® Cortex®−M3 processor cores for controlling various peripherals and the ONA10IV, a high−quality class D amplifier.
This whitepaper provides details on designing a high−performance, energy-efficient, voice-controlled Bluetooth speaker by incorporating ON Semiconductor products to achieve a full solution design.
