产品概述 返回TOP
The CXAR4178 is a stereo, fixed gain, single supply, and cap-free headphone driver, which is available in a WLCSP- 16 packages. The CXAR4178 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 selectable gain (0dB or 6dB) can minimize the external component counts and save the PCB space. High PSRR provides increased immunity to noise and RF rectification. The CXAR4178 is capable of driving 25mW at 3.6V into 16W load and provides thermal protection
