      CXAR41180是一款单声道的全差动架构音频放大器，当电源电压为5V时，连续传递1.36W平均功率至8Ω BTL负载，并使失真度(THD+N) 控制在1%以下，当电源电压为3.6V时，传递720mW至8Ω负载。The CXAR41180 is a mono fully-differential audio amplifier, capable of delivering 1.36W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V power supply, and 720mW to a 8Ω load from a 3.6V power supply. The CXAR41180 is ideal for PDA/smart phone application due to features such as -80-dB supply voltage rejection from 20Ha to 2kHz, improved RF rectification immunity, small 20mm2 PCB area, and a fast startup with minimal pop. The CXAR41180 is available in a MSOP-8 and in the space-saving 3mm × 3mm DFN package.
