Its THD is smaller than 1% under the above operation condition. For the low current consumption applications, the SHUTDOWN mode is supported to disable the CXAR41281/CXAR41281L when it is idle

   产品概述 返回TOPzks嘉泰姆

The CXAR41281/CXAR41281L is a stereo audio power amplifier in 16 pin TQFN3X3-16 with thermal pad package. It can drive 1.45W 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 SHUTDOWN mode is supported to disable the CXAR41281/CXAR41281L when it is idle. The current consumption can be further reduced to below 1μA. Giving the SHUTDOWN pin low level will drive the CXAR41281L entering the shutdown. Giving the SHUTDOWN pin high level will drive the CXAR41281entering the shutdown
