CXAR4178

CXAR4178是一款立体声、固定增益、单电源、无盖耳机驱动程序,可在WLCSP-16软件包中使用。CXAR4178是接地参考输出,无需输出电容器进行直流闭锁。消除输出电容器的优点是节省成本,消除元件高度,提高低频响应。内部可选择的增益(0dB或6dB)可以最小化外部元件数量并节省PCB空间。高PSRR提高了对噪声和RF整流的抗扰度。CXAR4178能够以3.6V的电压将25mW的功率驱动到16W的负载中,并提供热保护
·工作电压:2.4V~5.5V
·供电电流-VDD=3.6V时,I DD=2.1mA
·低关断电流
-VDD=3.6V时,I DD=0.7毫安
·接地参考输出
-无需输出电容器(用于直流闭锁)
-节省PCB空间
-降低BOM成本
-改善低频响应
·输出功率25mW/Ch在VDD=3.6V时转换为16W,THD+N=0.04%20mW/Ch在VDD=3.6V时转换为32W,THD+N=0.02%
·217Hz时高PSRR:90dB·快速启动时间:4ms
·集成De-pop电路
·热保护

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
