• AD7151/AD7156

         Hello All,

    I  want to use AD7151 or AD7156 C to D Converter.  The current consumption is a very critical for the application.

    My question is:

    What is the current consumption of the AD7151 and AD7156(with one enabled channel) in IDLE MODE?

    Best regards…

  • An issue about AD7151

    Hi,

     

    I encountered a strange problem while using AD7151 as a capacitance sensor in my current smart hardware design.

     

    AD7151 suffers from serious reading drifting in a specific circumstance where the capacitance should be fixed, but is reported as…

  • AD7151 as a human body sensor

    My client wants to use the AD7151 in skin care equipment.

    He wants to use it as a standalone (olny ues out signal), with two questions:
    1) If it is configured as below figure for skin recognition, can it be used without additional tuning?

  • AD7151测量漂移问题

    Hello,

    我在使用AD7151测量电容值时,遇到一种特殊的情况,在被测目标电容值(Data Register读数2600左右)较大的情况下,Data Register里的读数(本应该为常量)却每隔大概五分钟增加一。在电容值较小的情况下(小于2600),没有出现这种漂移的情况。

    我的外围电路和驱动我反复检查了,应该没有问题。不知道这种情况是否常见,是有可能由什么引起?


    谢谢
