   TI的老师，tlc2652应用中说在画电路板时，它的的输入引脚必须做GUARD环保护，请问我围绕输入引脚画一个导线环路，那这个环路应该接通地还是接通别的？

其次我在TI下载的tlc2652PSPICE模型是.101和.102结尾的文件，请问用仿真软件怎么处理才能仿真？

    Degradation from capacitor leakage becomes more apparent with the increasing temperatures. Low-leakage capacitors and standoffs are recommended for operation at TA = 125°C. In addition, guard bands are recommended around the capacitor connections on both sides of the printed circuit board to alleviate problems caused by surface leakage on circuit boards

    既然是信号隔离和保护用的, 应该接地

    你好，关于GUARD环保护设计，请参考下面应用手册 的“4.2.2 Guards and Shields ”部分：

    关于模型问题，试着把尾缀改成.txt的文件，然后在导入试下，参考这个帖子：
