A multi-level amplifier uses more, but smaller, transistors for delivering power to the speaker. This way, switching activity and power losses can be reduced significantly and more power is delivered to the speaker.
Multi-level Amplifier on a Chip
Martin Helms | Merus Audio
Can you tell us a little about Merus Audio?
Merus Audio is a young audio semiconductor company, founded and based in Copenhagen, Denmark.
We develop audio amplifiers that are fully integrated in a single chip. We focus on making the world’s most energy-efficient and compact amplifier solutions. On top of that, our amplifiers are extremely well-performing when it comes to audio quality.
Your multi-level eximo® amplifier is widely known for its efficiency. Can you tell us about eximo®, explain the technologies behind this amplifier’s success, and what audio solutions it is perfect for?
The eximo® multi-level amplifier technology is the only of its kind in the market. A multi-level amplifier uses more, but smaller, transistors for delivering power to the speaker. This way, switching activity and power losses can be reduced significantly and more power is delivered to the speaker.
Multi-level power conversion is not a new invention. It has been used in high-power inverters and motor drivers. Merus Audio has applied and refined the technology for audio amplification and combined it with an advanced power management system to minimize power losses under all conditions.
eximo® amplifiers are widely applicable across audio applications, simply because low power loss is a key advantage in almost all audio products. This is obvious in battery-powered applications where battery life can be extended considerably by using our amplifiers. Similar goes for PoE audio products as one wants to make the most of the limited…
