   产品概述 返回TOPOhR嘉泰姆

The CXAR4179 is a stereo, fixed gain, Cap-Free headphone driver which is available in a WLCSP2x2-16 package. The CXAR4179 is a ground-reference output, and doesn’t need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, PCB’s space, and component height. The built-in gain setting can minimize the external component counts and save the PCB space. High PSRR provides increased immunity to noise and RF rectification. In addition to these features, a fast startup time and small package size make the CXAR4179 an ideal choice for portable multimedia device. Moreover, the CXAR4179 is also equipped other features. For example, it is capable of driving 100mW at 3.3V into 16W, at THD+N=10% and provides thermal and short circuit protection.
