A New Era in Audio Performance with Infineonâ€™s MERUSâ„¢ Multilevel Class D Amplifiers

Click image to enlarge

Figure 1: MERUS™ amplifiers have a special power stage topology. In this design each half-bridge uses four MOSFETs (M1-M4) and the capacitor is “flying” between those to serve as an extra supply rail, resulting in a three-level output signal at the output switching node

A New Era in Audio Performance with Infineon’s MERUS™ Multilevel Class D Amplifiers

Rien Oortgiesen, Application Engineering Manager for Class D Audio, and Tybo Jens Jensen, Head of Application Engineering for Class D Audio, Infineon Technologies

Voices, noises, music – they are part of our lives. Sound has always been all around us. It connects us to our surroundings either we produce or just listen to them. Being an integral part of our everyday, conception and design of audio products and their environments have become more and more essential. In

IoT Connected Devices

Maximising Battery Life for IoT Devices on LPWANS

Vanja Samuelsson, Founder of Qoitech

It is generally agreed that the Internet of Things (IoT) has moved from the hype stage and is now about pragmatic adoption; a sentiment reflected by the fact that IoT has dropped from Gartner’s Hype Cycle for Emerging Technologies 2018 report, moving through its peak. It is now all about facilitating the interconnection

The Future of No-UV Lighting is LED

Clyde Porcella, Content Development Specialist & Customer Service, Access Fixtures

No-UV or UV-free lighting is commonly used in certain production facilities or clean rooms that use UV curing in their manufacturing processes. UV light causes some materials and products to cure or harden, which means that lighting for these facilities must be strictly controlled so as not to ruin batches of
