• Is it ok to put capacitors on the AD5686R reference output?

    The AD5686R has a very nice internal reference that I want to use as a reference throughout my board. This includes a SAR ADC which recommends a 1µF ceramic on its Ref input, to absorb the fast transients created during conversion. However, I don't know…

  • How to program AD5686R Evaluation Board SPI using arduino mega 2560?

    Hello!

    I am trying to program AD5686R Evaluation Board (EVAL-AD5686RSDZ) using arduino mega 2560. Does the SPI also needs to be in sports mode? How do i do that in arduino mega 2560? there are 4 SPI modes in arduino.

  • 关于AD5686R的VDD电压与最大输出电压的关系

    我的配置是gain=2,寄存器内写入的值是FFFF,参考电压用的是内部2.5V。datasheet上说当gain=2时,VDD的范围是Vref+1.5到5.5,也就是说,我现在参考电压是2.5V,gain=2,只要VDD在4V到5.5V之间,最大输出就应该在5V,但是当我给VDD的电压是4.66V时,其写入值为FFFF时,电压却也是4.66V,虽然会有偏差,但是这偏的有点多了吧,麻烦能给我解释一下吗,这个偏差也是容许的吗?谢谢!

  • AD5685R external reference

    Hello

    Can AD5685R use 4.096V or 2.048V external reference ?

    My customer would like to use AD5686R for 14bit, 4ch and  small package at 4.096V full-scale.

    The datasheet says that  impedance of REF pin is very low and  the internal reference 2.5V is enabled…

  • RE: EVAL-AD5689RSDZ user guide and evaluation software

    你好,依據EVAL-AD5686R user guide描述,軟件是使用ACE.

    我安裝了ACE及AD5686R的ACE pulgin.

    在ACE界面可以看到AD5689R EVK,雙擊後出現沒有plugin.

    請問是哪裡出問題呢?

    另外也試過AD5686R EVK軟體.

    該軟體並沒有看到AD5689R的選項.

    不管是選AD5686R或是AD5696R的選項後,都沒有認到AD5689R的EVK.

    請問是哪裡操作錯誤呢?

    謝謝.

  • supply voltage vs. output/input voltage on DACs and ADCs

    Hello,

    I am interested in using AD5686R and AD7682 for a lightweight analog data acquisition system. Right now, I am thinking about how to properly power these devices. One of my design constraints is that the device must be powered by a wall wart with…

    Hi ,

    Unfortunately, that's all we have, you may use the same data as AD5686R's.

    Hi Mark,

    I bought 29 pcs of AD5686R from Digikey. I have tested three of them with two different setup so far.

  • RE: AD5320 spice

    Hi,


    Just in case you will be needing four channels with unipolar outputs, you might want to consider AD5686R which has a SPICE model available.

  • RE: What is nanoDAC+?

    The new quad AD5686R/AD5685R/AD5684R nanoDAC+TM is a family of 16-bit/14-bit/12-bit, rail-to-rail, voltage output DACs. This family offers huge performance in a tiny package.

    What is new?

    The nanoDAC+TM family employ a new addressing scheme that allows…
