音频线路的电路保护

音频线路的电路保护



设计说明:

保护应用:
For audio circuits, the signal can have a maximum value of 5.5 Vp-p, and has a maximum frequency less than 30kHz. 在该频率下,不需要考虑抑制器的电容量。 存在ESD电气危害。
解决方案说明:
SPA TVS Diode Arrays or discrete diodes can be used for layout flexibility. In the upper schematic, a two-channel array is used to minimize part count. In the lower schematic two discrete 0201 diodes are used for flexibility and the smallest size parts.
配套解决方案:
If the customer cannot use 0201 size diodes, then the SP1003-01DTG device can be considered.
监管问题:
IEC 61000-4-2是最适合此接口的标准规范。 通过该测试可证明终端产品不易受到ESD危害。
特性:
