产品概述 返回TOP
The CXAR4180 is a stereo, fixed gain, single supply, and cap-free headphone driver, which is available in a WLCSP1.6x1.6-12and TDFN3x3-12 packages. The CXAR4180 is ground-reference output and don’t need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, eliminating component height, and improving the low frequency response. The internal fixed gain setting (-1.5V/V) can minimize the external component counts and save the PCB space. High PSRR provides increased immunity to noise and RF rectification. The CXAR4180 is capable of driving 50mW at 3.6V into 16W load and provides thermal protection.
