ADC development board for FPGA based Data Acquisition

Other Parts Discussed in Thread: ADS131A04, ADS1274, ADS1278

Hello!

I'm looking for an ADC development board that I can use with either the Zedboard (FMC connector) or the Altera DE10 - Standard (HMSC connector). I've spent a few weekends now scouring the TI website, but have haven't had much luck finding something that will work for my application.

I'm looking for an ADC that has 4-8 channels, 24 bit, and can sample each channel at 10kHz or greater. I've found the AD7768 development board from analog devices which will work with the Zedboard. However, my preference is to use the DE10 FPGA development board, because it has some dedicated external ram for the FPGA. I'm specifically looking for a development board because I would like to start developing as soon as possible, otherwise I would think about making my own hardware.

Any recommendations welcome!

Cheers,
Derry

Hi Derry,

Welcome to our e2e Forum!

We have a few 4 to 8 channel devices that might suit your needs. Please take a look at the ADS1274, ADS1278 and ADS131A04. These devices each have their own evaluation module, which also includes a controller board (unfortunately its pre-packaged, we can't ship the EVM by itself). From the development side of things, you would need to create a cable harness that connects the SPI Master from the LTC header to the evaluation module. We don't have any boards which would directly connect to the HSMC interface.

Hi Tom,

Thank you for the recommendations. I think any of those would suit my needs. My slight aversion to going that direction is the need to make the wiring harness. I'm also interested in connecting to the logic core on the development boards rather than the HPS, so there is some figuring out that would need be done there.

I did find this https://www.altera.com/content/dam/altera-www/global/en_US/pdfs/literature/an/an706.pdf which builds a case for going your suggested direction. I still need to put thought into this. Thanks agian!

Cheers!
