ADS1675EVM available soon ?

Other Parts Discussed in Thread: ADS1675, ADCPRO, PCM4222EVM, ADS1672

Hi

Got the ADS1672EVM-PDK, works perfect.

I was able to duplicate the THD numbers using a Krohn Hite 4400A oscillator.

Are there plans to offer a similar board for the ADS1675, too ?

    Hi Gary,

    I'm happy to hear you are getting good results with the ADS1672EVM!  Are you using the board with your own controller/software or did you get the ADS1672EVM-PDK with our ADCPro tool?

    Actually, the ADS1675REF board has been available for a few months now, you can find details here:

    http://focus.ti.com/docs/toolsw/folders/print/ads1675ref.html

    It's a little different setup than the ADS1672EVM.  On this design we needed to use an FPGA to 1) get the LVDS interface and 2) allow full speed operation of the ADS1675.

    Hi

    First, thanks for the quick response.

    Actually I used ADCpro & the PDK.

    I always did a search for EVM or PDK, why the REF naming for the ADS1675 board ?

    PS.

    Got 0.00005% ( yes, 4 zeros ) THD at the "sweet spot" input level -26dBFS at the PCM4222EVM from the Krohn Hite 4400A.

     BB, ups, TI rocks.

    Hi Gary,

    We use 'EVM' for the stand alone boards, and EVM-PDK for boards that use our regular Modular Mother Boards (the MMB0 on the ADS1672EVM-PDK setup for example).    The ADS1672 actually uses an FPGA card from a third party vendor named Opal Kelly (www.OpalKelly.com).  Since we did not use our own hardware as the controller for this setup, we referred to it as a reference design which is where the REF comes from.  The ADS1675REF actually uses the XEM3010 if you happen to check out the Opal Kelly website, it also uses ADCPro which is hardware agnostic.
