Evaluation board - audio board using highly power efficient analog-input multilevel MERUS™ class D amplifier IC MA12070
The audio evaluation kit contains all hardware and software elements that are needed to evaluate the highly power efficient MERUS™ analog input multilevel class D amplifier IC 2x80 W (MA12070). 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: analog
Recommended supply voltage (PVDD) range: 18 V to 26 V max.
Output noise level: <60 µVrms (AW)
Dynamic range: >109 dB
Idle power consumption at 26 VPVDD: <350 mW
List of components
Analog-input multilevel class D amplifier IC (MA12040)
Summary of Features
A configurable, single-voltage-suppl
y amplifier board
A PC programming interface board (with USB connection)
Coils to be used in series with standard resistive loads (to mimic speaker impedances) for more accurate efficiency measurements
A full set of documentation, 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
The evaluation kit provides an easy to use test and validation setup for the MA12070 multilevel amplifier IC
Allows users to experience the unique sound quality of a multilevel class D amplifier with an analog input and speaker setup of choice
Facilitates accurate power efficiency and audio performance measurements using standard audio analyzer hardware
Includes pre-recorded measurement data to help the user validate measurements from own test setup
Potential Applications
Portable audio – battery operated speakers, smart speaker, on-the-go Bluetooth speakers, docking speakers, boom boxes, wearable speakers
Home audio – multi-room systems, home hubs, televisions, soundbars, home theater systems, TVs
Voice controlled audio
Pro audio – PoE audio systems and other demanding audio applications where it is essential to maximize dynamic range and audio performance while minimizing power dissipation and power loss
