The MA12070P 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 rated power in a wide range of audio products. The MA12070P 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. An integrated digital-to-analog converter enables digital I2S audio stream input. It supports sample rates from 44.1 kHz to 192 kHz. Highly flexible output stage configurations are offered, ranging from four single-ended outputs to a single parallel-BTL output. The MA12070P features protection against DC, shortcircuits, over-temperature and under-voltage situations. Flexible “Power Mode Profiles” allow the user to utilize the multi-level switching technique for very low power loss or very high audio performance. Device communication and programming is controlled through an I2C interface as well as dedicated control pins.
