MA12070 Description

Short technical summary and product information.

The Infineon MA12070 is a highly efficient audio power amplifier based on proprietary multi-level switching technology. It operates from a 4V to 26V supply voltage range (PVDD) and a +5V system supply (DVDD, AVDD), making it suitable for various applications like battery-operated speakers, wireless speakers, and soundbars.

This amplifier features a digital power management scheme that dynamically adjusts switching frequency and modulation to optimize power loss and EMI. It offers high power efficiency, with idle power dissipation less than 160mW and efficiencies exceeding 80% at 2W and 91% at full power. Audio performance is also strong, with a DNR greater than 110dB and low distortion.

The MA12070 supports flexible output stage configurations, ranging from four single-ended outputs to a single parallel-BTL output. It includes comprehensive protection features against DC, short-circuits, over-temperature, and under-voltage situations. Device configuration is managed via an I2C interface or dedicated control pins.

The device is available in a 64-pin QFN package with an exposed thermal pad, designed for heatsink-free operation. Its filterless amplification capability simplifies design and reduces component count.
