Evaluation board – audio board using ultra-low idle power and inductor-less multilevel MERUS™ class D amplifier IC MA2304PNS
This board is discontinued. Please refer to the newer version EVAL_AUDIO_MA2304PNS
_B.
The EVAL_AUDIO_MA2304PNS is the evaluation board that features the MERUS™ multilevel MA2304PNS stereo class D amplifier. The MA2304PNS features ultralow idle power consumption, highest efficiency in the market at typical listening levels and reduced EMI in comparison to traditional 2 and 3 level class D amplifiers.
Summary of Features
MERUS™ multilevel switching technology
Output power: 2*37 W
Ultralow idle power consumption: 60 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 of dynamic rail tracking power supplies
Inductor-less and ferrite bead operation without compromising audio performance, efficiency and idle power consumption
Reduced footprint size and PCB area
