LM4673TMBD
概述
The LM4673 is a filterless 2.65W class D fully differential audio amplifier in an 8 pin LLP package. The LM4673 is designed to meet the demands of mobile phones and other portable communication devices. It is capable of delivering 1.24 Watts of average power to an 8 ohm load with less than 1% distortion (THD+N) from a 5V DC power supply.
