INFINEON EVALAUDIOMA2304DNSBTOBO1 Evaluation Kit, MA2304DNS, Class D Audio Power Amplifier, Audio

EVALAUDIOMA2304DNSBTOBO1 is an audio evaluation board using ultra-low idle power and inductor-less multilevel MERUS� class D amplifier IC MA2304DNS. The EVAL_AUDIO_MA2304DNS_B is the new version of MERUS� multilevel class D amplifier MA2304DNS evaluation board with a PSoC� controller. It features ultralow idle power consumption, the highest efficiency in the market at typical listening levels, and reduced EMI in comparison to traditional 2/3-level class D amplifiers. Additionally, MA2304DNS includes an integrated DSP for audio system tuning to facilitate development in a fast time-to-market environment. Typical applications include audio amplifiers, portable audio, battery-powered speakers and conferencing systems.
