MA12040P - Filterless and High-Efficiency 4V to 18V Audio Amplifier with I2S Digital Input
Product Overviews
MA12040P is a super-efficient audio power amplifier based on proprietary multi-level switching technology. It supports a 4-18V supply voltage range, allowing it to be used in many different applications. The MA12040P 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.
