DC2094A-A Evalboard

Hi there

I have bougth the Evalboard DC2094A-A, is tere the documentation for the SPI interface (used by Interface board DC890/DC2094) availeble, I'd like to interface the DC2094 to my own controller.

thanks for support &

best regards

Thomas

  • I have just reviewed the company and found a DC590 interface card. 
    According to demo Manuel CD2094A this device is supported, unfortunately the PScope does not find the DS590.
    Can I do anything, the DC590 is already a few years old (it is a SW update required)?
    best regards

  • Hi Thomas,

    QuikEval is the program to use with the DC590. PScope works with DC590 - notice that there are two separate sections in the demo manual.

    When using your own controller, it is probably best to connect directly to the ADC's SPI bus, I'll notify the apps engineer to make sure that there are no other considerations, like ensuring that the FPGA signals are tri-stated.

  • Hi Mark,

    I did some test with interface board DC590, but it looks like, the best way would be to use the SPI bus of the LTC2348 directly, because I would prefer a higher sampling rate than 100Hz and want to record over a longer period of time. Both does not work with the DC590. How can I turn off the FPGA so that the IOs are in tristate?
