产品概述 返回TOP
The CXAR41268 is a 5W audio amplifier with an alternative option between Class-D and Class-AB output which makes CXAR41268 very ideally for the applications efficiency-EMI compatible.CXAR41268 offers low THD+N, high SNR allowing it to achieve high-quality sound reproduction. The fully differential output with new fi lterless architecture(Class D mode) allows the device to drive the speaker directly,requiring no low-pass output filters and DC blocking capacitors, thus to save the system cost and PCB area The efficiency of the CXAR41268 is up to 90% It can extend the battery life, ideally for portable applications. The MD 8406 is fully protected against faults with short circuit protection and thermal protection.The CXAR41268 is available in SOP-16(EP)package.
