    CXAR41181是立体声音频功率放大器。它能在每个信息通道中将2W连续的RMS功率传送至3Ω负载中。当传送1W至8Ω扬声器时，CXAR41181的失真度(THD+N)将小于0.04%。The CXAR41181 is a stereo audio power amplifier that delivering 2W of continuous RMS power per channel into 3-Ω loads. When driving 1W into 8-Ω speakers, the CXAR41181 has less than 0.04% THD+N across its specified frequency range. Included within this device is integrated de-pop circuitry that virtually eliminates transients that cause noise in the speakers. Amplifier gain is externally configured by means of two resistors per input channel and does not require external compensation for settings of 2 to 20 in BTL mode (1 to 10 in SE mode). An internal input MUX allows two sets of stereo inputs to the amplifier. In notebook applications, where internal speakers are driven as BTL and the line (often headphone drive) outputs are required to be SE, the CXAR41181automatically switches into SE mode when the SE/BTL inputs is activated. Consume only 7mA of supply current during normal operation, and the CXAR41181also features a shutdown function for power sensitive applications, holding the supply current at 1μA.
