INFINEON MA12070XUMA1 Datasheet & Stock

Filterless and high-efficiency +4V to +26V audio amplifier with analogue input. Multi-level switching enables very low power loss during operation. In addition, it allows the amplifier to be used in filterless configurations at full rated power in a wide range of audio products. It features an embedded digital power management scheme. The power management algorithm dynamically adjusts switching frequency and modulation to optimize power loss and EMI across the output power range. Typical applications include battery operated speakers, wireless and docking speakers, soundbars, multiroom systems and home theatre systems.
