• RE: Question for your AN-1291

    Hi,

    To answer Q-1, I would like to clarify that the different retention time information are result of two different EEPROM blocks.

    For Q-2 and Q-3, the section named as "FAQs ABOUT DIGITAL POTENTIOMETERS WITH EEPROM MEMORY" does not apply…

  • On the EVAL-AD5292EVB, what is the resistance value (RAB = 20K, 50K or 100K) on the version of the AD5292 used on this board; i.e. what is the part suffix?

    Could you provide the full part number for the AD5292 used on the EVAL-AD5292EBZ? If the AD5292-100 is used and one wants to evaluate the AD5292-20, what do you recommend? Does one have to remove the AD9252 from the board and replace it with the version…

  • It questions on the EVAL-AD5292 data sheet.

    Hello.

    The main screen of the following document pg.4 and "AD5292 Evaluation Software (RevB)" is different.

    Hi Jacky,

    I have attached the User guide of AD5292 evaluation board. You can use the schematic in the User guide as a reference schematic.

  • Terminating Digital Pins of AD5292

    Hello,

    I intent to use AD5292 in my application for offset adjustment of a multi-stage amplifier system. I am going to program AD5292 externally and eventually I need to terminate digital pins of AD5292 appropriately. Which digital pins should I tie…

  • RE: AD5292 not working?

    Hi,

    According to the datasheet the AD5292 uses SPI timings with CPOL = 0 and CPHA = 1.

    So you need to set the mode field in your SPI board into to SPI_MODE_1.

    static struct spi_board_info spi_ad5292_dpot1 = {
       .modalias     = "ad5292",
       .max…
  • RE: AD5272+AD8421组成可编程增益,无输出

    如果AD8421的输入信号为正负的信号,那么增益电阻即AD5292电阻端的信号也是正负的,而AD5292电阻端允许的电压信号范围取决于其供电电源,试着用双电源给AD5292供电。

  • RE: AD5293 digital potentiometer wiper position not changing in response to programming

    To make this even confusing, this exact same setup works with AD5174 which also uses SPI Mode1 as AD5292.  The only thing I changed it to move the SPI wires and power wires to AD5174 with 5VDC for Vdd and Vss of AD5174 using the same application and commands…

  • RE: Noise of AD5292

    Hi Mark,

    The setup used to measure the AD5292 resistance noise spectra was the following:

    - We connected the R output to a voltage amplifier / filter (Stanford SR650), with a gain of x1000 and a low pass frequency of 40Hz.

    - Then the output of the…
