Delta Sigma电平转换缓冲模式

你好，迈克，
水平移位模式被设计成支持0V（接近接地导轨电压）。即使组件显示低于地面100mV，但这不是一个保证的规格PSoC，如数据表中指定的，预计将从VSSA到VDDA工作，并且只保证了多个范围。
最佳问候

  Hello Mike,
 
The level shift mode designed to support 0V( close to ground rail voltages). Even though the component shows 100mV below ground, this is not a guaranteed spec. PSoC as specified in the datasheet, is expected to work from VSSA to VDDA, and that much range is only guaranteed.

我的经验表明，它的测量低于地面测试的一个单位降至-103MV，可能已经走得更远。有什么信息会影响这个下限吗？我们计划在装运前对我们的单元进行校准，这样我们就可以验证它们在室温下会达到-100mV。有什么关于温度会发生什么的信息？
迈克。

  My experience has shown that it does measure below ground - tested one unit down to -103mV and may have gone further.  Is there any information on what will affect this lower limit?  We plan to calibrate our units before shipping so we can verify that they will go to -100mV at room temperature.  Any information on what may happen over temperature?
 
Mike.

你好，迈克，
由于在负范围内的转换只发生了，以确保绝对地面钢轨是可测量的，没有任何问题。由于这不是一个规格，我们不能保证，温度变化不表征。
最好的问候

  Hello Mike,
 
As the conversion over negative range happened only to ensure that absolute ground rail is measurable without any problem. As this is not a spec we do not guarantee, variation over temperature is not characterized.
