The MA12070P from Infineon is a super-efficient audio power amplifier utilizing proprietary multi-level switching technology. It operates with a supply voltage range of 4V to 26V, making it suitable for various applications. This amplifier features an embedded digital power management scheme that dynamically adjusts switching frequency and modulation for optimized power loss and EMI.
With an integrated digital-to-analog converter, it accepts digital I2S audio streams at sample rates from 44.1 kHz to 192 kHz. The MA12070P offers highly flexible output stage configurations, ranging from four single-ended outputs to a single parallel-BTL output. It provides 2x30W continuous output power into an 8Ω load at 22V supply and peak output power of 2x80W into 4Ω at 26V supply.
Key features include proprietary multi-level switching technology, high power efficiency (over 92% at full power), and audio performance with low noise and distortion. The device includes protection against DC, short-circuits, over-temperature, and under-voltage situations. Communication and programming are handled via an I2C interface.
The MA12070P is available in a 64-pin QFN package with an exposed thermal pad, designed for heatsink-free operation. Its applications include battery-operated speakers, wireless and docking speakers, soundbars, multiroom systems, and home theater systems.
