Overview

BelaSigna® 300 is an ultra-low power, high fidelity monaural audio processor for portable communication devices that delivers superior audio clarity without compromising size or battery life.
BelaSigna 300 provides the basis for superior audio performance in devices susceptible to noise and echo. Its unique patented dual-core architecture enables multiple advanced algorithms to run simultaneously, while maintaining ultra-low power consumption. With little-to-no impact on battery life or form factor, the miniature ultra-low-power, single chip solution is ideal for use in portable devices.

With domain expertise and best-in-class algorithms, ON Semiconductor and our network of solution partners can help you develop and launch products quickly. BelaSigna 300 chips are backed by a comprehensive suite of development tools, hands-on training and full technical support.
