LM4941SDBD
概述
The LM4941 is a W class AB fully differential audio amplifier in a tiny leadless leadframe package. The LM4941 is designed to meet the demands of portable devices. It is capable of delivering 1.25 Watts of average power to an 8 ohm load with less than 1% distortion (THD+N) from a 5V DC power supply.
The LM4941SDBD is an evaluation board designed to ease evaluation and effort during the development of a circuit using the LM4941SD. It is an easy-to-use stand-alone board that requires power and GND, a differential input signal and an output load.
