      CXAR41182A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，能连续传递3W平均功率至3Ω BTL负载，并使失真度(THD+N)控制在10%以下。当电源电压为3.6V时，能传递720mW至8Ω负载。The CXAR41182A is a mono fully-differential audio amplifier, capable of delivering 3W of continuous average power to an 3Ω BTL load with less than 10% distortion (THD+N) from a 5V power supply, and 720mW to a 8Ω load from a 3.6V power supply. The CXAR41182A is ideal for PDA/notebook and portable devices application due to features such as -80-dB supply voltage rejection from 20Ha to 2kHz, improved RF rectification immunity, and a fast startup with minimal pop. The CXAR41182A is available in a SOP-8(FD).
