• AD5291 won't update wiper value

    Hello to all you guys, I am new here and right now  have been working for 2 days with this component. I've been searching and finally made it work. I use Arduino Uno to control the values and using the SPI bus.  

    The problem is that if I want to change…

  • RE: 请问ADI有双极性供电的数字电位计吗?

    AD5291/AD5292,AD5293

    • 单电源供电: 9 V至 33 V
    • 双电源供电: ±9 V 至±16.5 V

    与你要求接近,好像没有±8 V 的,有±2.5 V~±2.75 V双电源供电的。

  • RE: Question for D-POT AD5292BRUZ

    Hi Kaos-san,

    The 20-TP is not EEPROM but rather fuses. This is stated in the 1st page of the data sheet.

    The AD5291 and AD5292 do not require any external voltage supply to facilitate fuse blow, and there are 20 opportunities for permanent programming…

  • AD5292 operation voltage.

    Hi

    I would like to make sure about AD5291/AD5292 opration voltage.

    Data sheet say

    Feature: +9V to +33V single-supply operation.

    General Description:

    "These devices are capable of operating across a wide voltage range, supporting both dual supply…

  • RE: Any restrictions on AC coupling of AD5291/5292 digital pot?

    Hi Brian,

    I believe it is fine as long as the signal frequency do not go over beyond the specified bandwidth in the data sheet.

  • digiPot common GNDs (AD5292/91)

    Greetings

    I have a rather general question regarding the AD5292/5291: Is it okay/should I connect Vss and B?

    I am asking, because I am currently using four of them in a daisy chain configuration. It seems though one of them is kind of damaged (by now…

  • AD5292 not works (half-works)

    Hi all. I see this chip very popular because many people can't get it working. I decided to make new topic because my case is little different.

    First of all, I should say that we already read all previous topics carefully, studied whole datasheet…

  • 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…

  • RE: The AD5291 datasheet is confusing on the topic of VDD voltage range.  Is it +9 to +33V or +21 to +33V?

    Hi Steve,

    Thank you for pointing this out. I will verify this internally and will get back to you as soon as possible.

    Regards,

    Mark
