New at Mouser: Infineon Technologies MA2304xN MERUS Multilevel Switching Amplifiers for Wireless Audio Applications

March 15, 2023 – Mouser Electronics, Inc., the New Product Introduction (NPI) leader™ empowering innovation, is now stocking the MA2304xN MERUS™ multilevel switching amplifiers from Infineon Technologies. The MA2304xN MERUS™ series provides engineers with unmatched power efficiency at both low and high output power for wireless and Bluetooth® speakers, soundbars, and battery-powered designs for conference and multichannel room audio systems.

Mouser Electronics now stocks the latest lineup of Infineon products including the MA2304DNS and MA2304PNS amplifiers. The MA2304DNS is a 2 × 37 W audio amplifier with fully integrated and configurable DSP (digital signal processing) with I2S/TDM (time division multiplexing) audio interface. It features MERUS multilevel switching amplifier technology, enabling unmatched power efficiency at both low and high output power, without the necessity for a heatsink or a traditional LC filter. Multilevel switching also reduces EMI (electromagnetic interference) and enables inductor‑less applications with lower cost and no compromise in audio performance or efficiency. A high-order internal feedback loop ensures low THD (total harmonic distortion) for excellent audio performance.

The MA2304PNS offers a simpler volume control and limiter for systems where an application/connectivity processor does the audio processing. This makes the MA2304PNS ideal for battery-powered speaker applications where extended battery life and/or reduced battery cell cost are crucial. Featuring an audio limiter and volume control with ultra‑low idle power consumption, five times lower than the traditional class D audio amplifiers, the MA2304PNS is also optimal for In-mains powered multichannel applications where reduced and scalable EMI performance facilitates designs, without the need for a heatsink.

The Infineon MA2304DNS and MA2304PNS are supported by the EVAL_AUDIO_MA2304DNS and EVAL_AUDIO_MA2304PNS evaluation boards. The evaluation boards enable the user to demonstrate the features of the MERUS amplifiers, including energy efficiency, audio performance, and their adaptive power management system.
