ft2830
Description
The ft2830 is a highly efficient 4.5W Class-G audio power amplifier with automatic level control (ALC) for use in battery-powered portable devices. It integrates a filterless Class-D audio power amplifier with a Class-G charge pump regulator based upon proprietary Dual-PumpTM topology.
Key Features
