Low Supply Current, 50mW Stereo Cap-Free Headphone Driver CXAR4181 is ground-reference output, and no need the output capacitors for DC blocking. The advantages of eliminating the output capacitor

The CXAR4181 is a stereo, fixed gain, single supply, and cap-free headphone driver, which is available in a WLCSP1.6x1.6-12 package. The CXAR4181 is ground-reference output, and no 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. LDO is the best solution for microphone detection circuit requirement, and it can lower the total BOM costs. The CXAR4181 is capable of driving 50mW at 3.6V into16W load, and provides thermal protection.
