INFINEON MA12070XUMA1 High-Efficiency Audio Amplifier
This is a high-efficiency, filterless audio amplifier capable of operating with an input voltage range from +4V to +26V. It features proprietary multi-level switching technology with 3-level and 5-level modulation, coupled with an embedded digital power management system that dynamically optimizes switching frequency and modulation to reduce power loss and electromagnetic interference across the output power range. Designed for versatile audio applications, it supports full-rated power operation in filterless configurations, ideal for battery-operated speakers, wireless and docking speakers, soundbars, multiroom audio systems, and home theaters. The amplifier includes support for selectable gain (20dB or 26dB), delivers 2 x 30W continuous and 2 x 80W peak power, and incorporates advanced protections such as undervoltage lockout, over-temperature warnings, DC and short-circuit protections. Its high-performance audio quality features integrated noise below 45 µV (A-weighted), THD+N of 0.004%, and 4th order feedback error control. Error reporting is accessible via an I2C serial interface.
