The efficiency and diagnostics necessary for automotive emergency call (eCall) systems generate unique requirements for the audio subsystem, such as recording diagnostics, speaker diagnostics and low power consumption. This design shows how to use our automotive, two-channel audio codec and a class-D audio amplifier for eCall applications. The reference design also highlights critical design factors and benefits of our design such as low-power consumption and efficiency, loud and clear audio output, and integrated diagnostics and protection.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
