                             Sample Description
================================================================================
功能描述：
此样例演示了OPA的独立模式功能,OPA的负端和输出端短接，输出端会输出和正端一样的电
压值。

Function descriptions:
This example demonstrates the independent mode function of OPA, where the
negative and output terminals of OPA are short circuited, and the output 
terminal outputs the same electrical output as the positive terminal value.
