产品概述 返回TOP
The CXAR41265 is a class-D audio amplifier. It can provide 3W output Power and low THD+N, allow
ing it to achieve high quality sound reproduction.The new filterless architecture allows the device
to drive the speaker directly, requiring no lowpass output filters,thus to save the system cost
and PCB area.With the same numbers of external components,the efficiency of the CXAR41265
is much better than that of class-AB cousins.It can extend the battery
life, ideal for portable applications.The CXAR41265 is available in SOP-16 package.
