The MA12070 is a super-efficient audio power amplifier based on proprietary multi-level switching technology. It supports a 4-26V supply voltage range, allowing it to be used in many different applications. Multi-level switching enables very low power loss during operation. In addition, it allows the amplifier to be used in filterless configurations at full .
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. A 4th order feedback loop ensures low distortion and a high PSRR. The MA12070 operates from a single power stage supply voltage (PVDD) and a +5V system supply voltage (DVDD, AVDD). Highly flexible output stage configurations are offered, ranging from four single-ended outputs to .
