About Infineon's audio amplifier solutions

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 endpoints, 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, and 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.

Benefits delivered by Infineon's audio amplifiers

Infineon's audio amplifiers deliver many benefits for the designer and the end user. For example, our MERUS™ range of advanced audio amplifier solutions maximizes power efficiency, output power, and audio performance while ensuring maximum design freedom and fast time to market.

In addition, our solutions excel in the following areas:

  • Reliability: Thanks to the enhanced design and production standards, you can count on our solutions to provide complete system stability and reliability over the entire product lifetime.
  • Performance: We empower you to create heatsink-free and filter-free high-performance audio products, with fewer components. This lowers overall system costs and, for portable applications, enables longer battery playback time.
  • Flexibility: Our wide selection of ready-to-use amplifier solutions and reference designs fit most Class D audio design targets, allowing you to launch products faster.
Home audio amplifier solutions

Modern home audio products come in many shapes, sizes, and configurations. 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™ audio 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.

Better sound, higher power density, and heatsink-free MERUS™ integrated Class D amplifiers. 

Professional audio amplifier solutions

Professional audio equipment is all about maximizing output power and power density. In the past, professional audio electronics were 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 build both amplifiers and power supply units with great audio performance and high efficiency in a very compact space. For engineers developing audio amplifier applications, Infineon offers both monolithic and chipset solutions with versatile MOSFET combinations for the scaling of output power. 

High-power, high-reliability, and high-flexibility MERUS™ discrete Class D solutions with Infineon MOSFETs or GaN HEMTs. 

Portable audio amplifier solutions

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