• RE: IBIS Model or S-parameter file for AD8403

    Hi 

    We do not have the IBIS model or S-parameter for AD8403.

  • AD8403 read backs

    Does anyone have any experience reading from the AD8403 over the SPI bus?  I'd like to verify my writes are indeed working.

  • AD8403 - 1k Part

    Hi

    We want to use the AD8403-1K part for my led current control application, We have few questions as below

    1) I want to use VDD voltage as 3.3V, but LED Supply as the 5V between Ra and Rw, Can it be possible? Rb we will connect to the ground.

    2) Can…

  • AD8403: Connecting to digital

    I would like to know is there any problem connecting several digital pot.
    AD8403 on the same SPI bus while giving a uniq CS for each chip (not a daisy
    chain).

    So all SDI's connected to the controller's output signal, all CLK's connected…
  • AD8403 - SDPAPI interface

    Hi

     

    I am trying to communicate to the AD8403 Evaluation board via SDP-B platform. I have received an evaluation software with the board which works fine. I would like to communicate to the board via VB.net script and hence I am using the sdpapi1.dll…

  • Interfacing ARM and AD8403(Digital Potentiometer)

    Dear sir/mam,

            As i am working interfacing ARM and AD8403 IC(digital potentiometer),i am measure resistance value,what i am doing is from ARM i am sending data through SPI every 20sec data i am tranmitting,and AD8403 IC what i am sending it will give…

  • AD8403 Evaluation board resistance range

    Hello.

    I wish to know what is the Resistance range of the AD8403 IC that exists on the AD8403 Evaluation board (the EVAL-AD8403SDZ).
    Is It 1K Ohm? 

  • 问题: AD8403问题

    最近在用AD8403这款数字电位器,但是遇到了一些问题希望得到解决。
    1、定位器输出的电阻可不可以在通电的状态下用万用表来测量。
    2、用万用表测量发现电阻不准,10k的测量出来却只有9.2k而且不稳地。
    3、线性不是太好,每次步进的阻值相差较多

  • AD620与AD8403一起使用的问题

            AD620放大带有2v偏置的交流小信号(几十mv,频率在100hz左右),单片机STM32控制可编程电阻器AD8403调节AD620的放大倍数,AD620输出前和输出后的rc滤波器去除交流小信号的2v直流偏置,具体电路如下图,

    电路设计出来遇到的问题:1、AD620的增益跟调节预期相差很大;

                                              2、AD620所能放大的信号频率只有400HZ不到,跟手册上所说的带宽严重不符;

                                              3、当IN+无输入时,out端有1v的直流电压输出,即使IN+和IN-短接接到地还是有1V的电压输出。
