产品概述 返回TOPxHh嘉泰姆
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
