Reference board – audio board using highly power efficient analog input multilevel MERUS™ class D amplifier IC MA12040
This board is a size optimized implementation example for the highly power efficient MERUS™ analog input multilevel class D amplifier IC 2x40 W (MA12040). The IC is specifically targeted for high performance filter-less and heatsink-free audio applications.
Configurable number of audio channels: 2xBTL or 1xPBTL
Audio input format: analog
Recommended supply voltage (PVDD) range: 10 V to 18 V max.
Output noise level: <60 µVrms (AW)
Dynamic range: >106 dB
Idle power consumption at 18 V PVDD: <300 mW
Summary of Features
The multilevel amplifier IC reference board can be used directly for intended audio applications or rapid prototypes
Single-voltage-suppl
y amplifier board
Benefits
The board has a small form factor and will fit in most audio designs
Allows users to experience the unique sound quality of a multilevel class D amplifier with an analog input and speaker setup of choice
Potential Applications
Portable audio – battery operated speakers, on-the-go Bluetooth speakers, docking speakers, boom boxes, wearable speakers
Home audio – multi-room systems, television, soundbars, home theater systems, stand-alone components
Pro audio – active monitor speakers, power-over-ethernet (PoE), multi-channel systems
Voice controlled audio
