Superior Audio Performance and Efficiency without Compromise
With the combination of MPS and Axign technologies and solutions, Class-D audio amplifier designers will no longer be forced to choose between audio quality and efficiency. Axign’s customer-proven expertise in digital signal processing and analog/power/mixed-signal design for consumer and automotive audio applications perfectly complements MPS’s strengths in design and process development, packaging, and manufacturing. Our teams share a passion for delivering complete solutions that exceed our customers’ expectations.
The Sound of Innovation
Traditional Class-D audio amplifiers struggle to deliver low distortion levels throughout the full audio frequency range, and are forced to trade off power consumption for audio fidelity. MPS + Axign’s solution leverages ultra-fast data conversion and a fully digital control loop to take feedback directly from the loudspeaker, instead of before the power stage’s output filter. This architecture not only ensures that the sound from the loudspeaker is an accurate reproduction of the audio source, but also enables such precise control of the Class-D pulse-width modulation (PWM) signals that negligible power is consumed in the power stage or output filter.
