TI中文支持网Part Number:TMS320F28388DOther Parts Discussed in Thread:TINA-TI
spract6a文档为《ADC Input Circuit Evaluation for C2000 MCUs (using TINA-TI simulation tool)》
以文档第10页的仿真电路图为例
我不太理解处理器内部是怎么实现对采样保持电容放电的。
如上图所示，文档中设计了10nS的放电时间，这有什么依据吗？
Ben Qin：
你好，我咨询下相关资深工程师，一旦有回复会立即回复您。

Ben Qin：
请参考下工程师的回复：
This is a behavioral model, so not every part of it will necessarily represent real-world performance. What it should do is correctly model the input drive requirements for the modeled ADC, based on our design data. The actual discharge time in this case is not particularly important – in the real world, discharge would not actually happen unless the next conversion was for a zero voltage. Discharge is only needed here for the sake of looping/restarting the sample/hold cap charging model.

您好 感谢帮助 提出这个问题主要是担心crsoss talk的问题 我找到了一份相关的文档 去学习下
