Cooler, smaller and lighter amplifiers for great sounding audio products
In addition to creating great sounding products, manufacturers of the latest home audio devices are under pressure to deliver products that are wirelessly connected, portable and adaptive to different use cases and environments. At the same time, audio products are becoming increasingly complex to design. On the one hand, this is due to demand for new functions such as voice command interfaces. On the other, audio products must accommodate cloud-based networks along with an ever-increasing number of end-points, audio channels and audio sources.
As a result, the audio hardware solutions used for audio products must be:
- Smaller and lighter
- More integrated
- Better connected
- Power efficient
- Cost effective
- Easier to use
At Infineon, we manufacture power-efficient class D audio amplifier solutions that maintain best-in-class audio quality, without heating up the surroundings. We believe smaller and lighter is better, and big and bulky is history. This means the amplifier embedded in your product should be heard, but not seen. Our amplifier solutions help you design robust, flexible products that meet the needs of your customers, and the market.
Modern home audio products come in many shapes, sizes and configurations but one thing they all have in common is the requirement for great sound in combination with outstanding industrial and acoustic design. In addition to producing exceptional sound quality, MERUS™ amplifiers from Infineon can completely eliminate the need for bulky and expensive LC output filters and heatsinks. This allows design of new innovative and great sounding home audio products in form factors and shapes that were previously unthinkable.

When designing portable/battery powered audio devices, it is essential to maximize battery playback time, and at the same time, maintain an excellent audio performance. Infineon’s MERUS™ amplifiers provide up to twice as long battery playback time in combination with the best-in-class audio performance and unsurpassed sound quality.

Professional audio equipment is all about maximizing output power and power density. Professional audio electronics used to be big, heavy and not very energy-efficient. But with the conception of Infineon's MERUS™ multilevel class D technology and gallium nitride CoolGaN™ e-mode HEMTs, it is now possible to conceive both amplifiers and power supplies units with great audio performance and high efficiency in a very compact space. For engineers developing amplifiers, Infineon offers both monolithic and chip-set solutions with versatile MOSFET combinations for the scaling of output power.
