Problem
Traditional audio amplifiers introduce distortions in the power stage and analog output filter, compromising sound quality and limiting the fidelity of audio reproduction. Existing solutions often struggle to deliver high efficiency, low noise, and precise control over loudspeaker behavior simultaneously.
Solution
Axign (now part of Monolithic Power Systems) develops digital audio controller ICs leveraging patented Digital Loop technology to minimize distortions and enhance audio performance. Their solutions employ a fully digital control loop with post-filter feedback to achieve exceptional sound quality, characterized by low total harmonic distortion (THD+N), high dynamic range, and a high damping factor. This technology enables precise loudspeaker control and efficient power usage, catering to the demand for superior audio fidelity in various applications.
Target Audience
The primary target audience includes manufacturers of home audio equipment and portable audio devices seeking high-fidelity, energy-efficient digital amplifier solutions.
