MA12070 - Filterless and High-Efficiency +4V to +26V Audio Amplifier

General Description

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.

Key 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. 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.
