Hypex Introduces DSA254 Amplifier Module with NCOREx Technology

Expanding its OEM solutions catalog, the new DSA254 OEM is a cutting-edge audio amplifier module from Hypex Electronics, designed for flexibility and to transcend the boundaries of traditional loudspeaker systems. The new Hypex DSA254 leverages the company's latest NCOREx technology, launched with the NCx500 OEM module, which lowers the distortion and source impedance by a factor of two compared to the previous NCORE series.

The AX5689 is an eight-channel audio amplifier controller IC with digital inputs and CMOS level PWM outputs, enabling high-order digital control loops with post-filter feedback. This article, originally published in audioXpress, December 2023, reviews the Axign and GaN Systems Class-D audio amplifier reference design board, intended to demonstrate the benefits of Axign's digital controllers and its unique approach.

Infineon Technologies announced a new family of 2x 37W audio amplifiers featuring the second generation of MERUS multilevel switching amplifier technology. Optimized for low power and battery-powered applications, the new devices are the MA2304DNS with an integrated and fully-configurable digital signal processor (DSP), and the MA2304PNS with audio limiter and volume control features. Both are now the most efficient in the Infineon MERUS family, with an idle power mode at least five times lower than traditional class D audio amplifiers.

Unlocking the potential of its best-in-class power MOSFET technology, Infineon Technologies introduced the MERUS 2-channel, analog input, class D audio amplifier multichip module (MCM) MA5332MS, adding a higher power and smaller footprint device to its MERUS technology family. It is a powerful upgrade to its predecessor, offering the same or even higher output power than monolithic alternatives, without a heatsink and 50 percent less footprint.
