LM4941TMBD
具有射频抑制和停机功能的 1.25 瓦全差动音频功率放大器
LM4941TMBD
概述
The LM4941 is a W class AB fully differential audio amplifier in a tiny 0.4mm pitch micro SMD package. The LM4941 is designed to meet the demands of mobile phones and other portable communication 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 LM4941TMBD is an evaluation board designed to ease evaluation and effort during the development of a circuit using the LM4941TM. It is an easy-to-use stand-alone board that requires power and GND, a differential input signal and an output load.
