• RE: AD5270 Digital pot programming question

    Hi Arun,

    You can connect 4 x AD5270 modules, you will need to send 16 x 4 = 64 bits.

    Lets say we have 4 AD5270 digiPOTs ( U1, U2, U3, U4),

    U1 ->DCEN-> U2 ->DCEN -> U3 ->DCEN -> U4

    The first 16 bits you send goes to U4, Next 16…

  • RE: AD5270 Command Operation

    Hi Mark,

    Thank you for your answer. Our customer tried it, but AD5270 was no responding. On the other hand, the customer tried to change the timing of the SPI.

    The following is NG case;

    And the following is OK case;

    I can't find the timing specification…

  • AD5270/AD5271 datasheet typo?

    Hello,

    I got some point out about AD5270/AD5271 datasheet.

    It seems not "Table 13" but "Table 15" at below passages.

    1) 3rd and 8th lines at 50-TP MEMORY BLOCK on page 18

    2) 10th line at RDAC AND 50-TP READ OPERATION on page…

  • ADR44x and automatic output adjustment

    I'd like to avoid mechanical trimmer for adjusting the output voltage.

    Is good idea use Digital Rheostat AD5270 in Trim circuits or  noise and thermal drift digital potentiometer completely kills accuracy ADR44x?

  • RE: AD5270 Maximum Code Loss vs Temperature

    Hi Gregor,

    In ADI, we define code loss as the range of codes which are having the resistance tolerance above or below a certain percentage. In the case of AD5270, the resistance tolerance for the code loss is ±1%.

  • AD527x, how to measure the resistance value of digipot

    I used SDF to plug in EVAL-AD527XSDZ and power the system by one USB port of
    the laptop, then using multimeter to test the resistance and compared with the
    target value shown in the software.
    1)      If using Agilent 34401A digital multimeter…
  • AD5270数字电位计有参考程序吗?

    看了几天芯片资料,并用stm32开发板联机调试了几天,阻值一直固定在9.8K不变化。

    有AD5270的参考程序吗?

  • AD5270的解决方案?

    最近选用一款型号为“AD5270”的20K数字电位器进行开发。按照官程写却一直为9.8K左右。用示波器抓过脉冲和数据手册上是一致。但A和W端的阻值就是不变。不知能否提供一份例程或者例子进行参考?
