Audio Amplifiers - Reliable, High-Performance and Flexible

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.

Providing the products and tools you need to overcome most Class D audio design challenges, Infineon offers a unique portfolio of MERUS™ amplifier solutions. Depending on your exact project specifications, choose from our high-performance Class D amplifier solutions for all power ranges and application requirements, from the smallest fully integrated single-chip solutions to highly scalable driver and discrete MOSFET combinations.

By paring our core competencies and leadership in power semiconductor process technologies with groundbreaking innovation in new audio architectures, such as our new multi-level Class D amplifier ICs, we are able to provide solutions that are smaller and lighter, and run cooler. This enables audio product manufacturers to design cost-effective, better sounding audio products.

In addition to amplifier solutions, we also offer ones for battery chargers, switch mode power supplies as well as battery and power management devices, microprocessors and MEMS microphones.

Our MERUS^TM 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 products excel in the following areas:

• Reliability: Thanks to enhanced design and production standards, customers can count on our solutions to provide complete system stability and reliability over the entire product lifetime.
• Performance: We empower customers to create heat sink-free and filter-free high performance audio products, with fewer components. This lowers overall system costs and, for wireless 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.
