Evaluation board - audio board using highly power efficient digital-input multilevel MERUS™ class D amplifier IC MA12040P
This audio evaluation kit contains all hardware and software elements that are needed to evaluate the highly power efficient MERUS™ digital input multilevel class D amplifier IC 2x40 W (MA12040P). The IC is specifically targeted for high performance filter-less and heatsink-free audio applications.
Configurable number of audio channels: 2xBTL or 4xSE or 1xBTL+2xSE
Audio input format: digital (I2S)
Recommended supply voltage (PVDD) range: Â 10 V to 28 V max.
Output noise level: <150 µVrms (AW)
Dynamic range: Â >97 dB
Idle power consumption at 18 V PVDD: <350 mW
List of components
Digital-input multilevel class D amplifier IC (MA12040P)
Summary of Features
Summary of features
Configurable, single-voltage-suppl
y amplifier board
PC programming interface board (w. USB connection)
Coils to be used in series with standard resistive loads (to mimic speaker impedances) for more accurate efficiency measurements
Full set of documentation, with a Windows based graphical user interface for PC installation and 1:1 measurement data for this specific amplifier board (all provided on the included memory stick)
Benefits
