Open Audio Platform for High-End Active Headphones

With the rise of high-quality online media streaming, headphones are no longer a simple accessory – they are the gateway to entertainment. Renesas' SmartBeat™ DA14195 offers a simple route to active headphones with built-in audio processing. Based on industry-standard IP, this powerful System-on-Chip (SoC) enables headphones that control ambient noise and enhance content for truly immersive listening anywhere.

The DA14195 is an open audio platform for high-end active headphones. It combines extremely low power consumption with impressive processing performance in a small package. As a result, it allows users to develop attractive looking headphones that deliver top-end features such as ambient noise/echo cancellation, virtual surround sound and voice control. It supports up to 6 mics for beamforming and position-aware applications. Plus, it handles high-end audio signals such as 192kHz, 32-bit pulse-code modulation (PCM) for the ultimate sound quality.
