• SPI Mode for DigiPots (AD5122)

    Hi All,

    I'm attempting to confirm the SPI Mode of the AD5122 Digital Pot.

    http://www.analog.com/static/imported-files/data_sheets/AD5122_5142.pdf

    It's noted/obvious in the datasheet that data is latched on the falling edge of SCLK.

    What's…

  • AD5141_datasheet

    Please let me know  about  "Figure 19. Rheostat Mode Temperature Coefficient ((ΔRWB/RWB)/ΔT × 106 ) vs. Code " described on p.15 of the datasheet.

    If you look at the datasheet of AD5121, the horizontal axis of the above items…

  • Automotive parts for Nonvolatile Digital Potentiometer

    Dear Sir,

        I was sorting the automotive recommended part of digiPOTs in website, and found AD5122 in the list;

    and search ADI Compass, the result was the same.

    But in AD5122 datasheet, I could not find any automotive part in ordering guide list, so…

  • RE: Is there a table on which SPI DigiPOT is compatible with which other ones?

    Exactly that is why I have asked.

    The datasheet of the AD5122/AD5142is a bit cryptic with the actual SPI mode (and if I recall correctly, the AD5292 is silent about mode at all).

    It would be just good to hear "yes, the AD5142 fits into a chain of AD5292s…

  • RE: AD5123/AD5143 数字电位计 ±6 dB增量和减量指令问题

    关于+/-6db增量和减量指令,是指的对于数字电位计的一种特殊控制,在音频/视频以及LED驱动中常用到,可以简化数字码字的控制,具体的说明您可以看一下AD5122 的中文数据手册:http://www.analog.com/static/imported-files/zh/data_sheets/AD5122_5142_cn.pdf

    在手册的表14中给出了执行几次对应命令所得到的数字码值,然后就可以计算对应的阻值了,和您提到的误差不是一个概念。
