EVAL_AUDIO_MA2304DNS_B

Overview

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
