• 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? 

  • RE: AD8403A10 communication Check !

    Hi koka,

    Safety in the communication lines must be embedded to the design of the chip. The AD8403 cannot interpret any additional data that the microcontroller sends and the only way to check if the data is incorrect is if the AD8403 doesn't respond…

  • RE: AD8403 - SDPAPI interface

    Hi,

    Unfortunately I cant help with the code but I'll try to help with the setup:

    First, have you setup the GPIO pins of the SDP board?

    Figures 11 and 13 of the UG-255 will help this explanation:

    Since this is a multiDAC board, there are different…

  • Comment on AD8403: Connecting to digital

    Hello,

    I use AD8403 A10 digital potentiometer.Is a 10K potentiometer ? is it true, why I write "0001000000" and must have 2.5 k(10k/256 * 64) between W1 and A1 pins but I see 2k in these pins ? what's problem ?
