Other Parts Discussed in Thread: ADS8471, OMAP-L138, ADS5560

I would like to know whether there is the ADC which can connect directly to uPP.

Here is a way to connect ADS8471 to OMAP-L138 via uPP.

http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/144344.aspx

A BUSY pin of ADS8471 is tied to a CHx_CLK pin of OMAP-L138. I guess that it does not meet the setup time.

Is not there the ADC which can connect directly to uPP?

Best regards,

Hi Daisuke,

I don't have any examples of an ADC connected directly to a uPP interface. After looking at the interface for the ADS8471 I'm not sure it's the best candidate. You should be looking for an ADC that has synchronous parallel output that would be more compatible with the streaming capabilities of the uPP. The paper at the link below describes a method of connecting the ADS5560 with a uPP interface. Although some glue logic is needed, this part has a parallel interface much better suited to a connection with the uPP then the ADS8471.

More details on the uPP interface can be found at the TI twiki at http://processors.wiki.ti.com/index.php/Introduction_to_uPP

Hi Bill,

Thank you for your reply.

I am going to find ADC with an interface like ADS5560.

Best regards,
