Evaluation board –audio 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.
Summary of Features
MERUS™ multilevel switching technology
Output power: 2*37 W
Ultralow idle power consumption: 52 mW
Configurable switching edge steepness
PWM sync for reduced EMI in multichannel systems
79% efficiency @ 1 W, 8 Ohm
Digital I2S/TDM inputs
Output noise: 52 uVrms A-weighted
Benefits
Extended battery life and reduced EMI
Lower system cost and simple implementation without the need for dynamic rail tracking power supplies
