产品概述 返回TOP
The CXAR41275 is a mono audio power amplifier in MSOP-8 (FD), TDFN3X3-8 and WLCSP2X4-8 package. It can drive 2W continuous RMS power into 4Ω load in Bridge- Tied Load (BTL) mode at 5V supply voltage. Its THD is smaller than 1% under the above operation condition. For the low current consumption applications, the SHDN mode is supported to disable the CXAR41275 when it is idle. The current consumption can be further reduced to below 1μA. Giving the SHUTDOWN pin low level will drive the CXAR41275 entering the shutdown.
