ADS8548 VQFN(RGC) Footprint Files

Other Parts Discussed in Thread: ADS6442, ADS8568, ADS8568EVM-PDK

Footprint files for the VQFN package are not on the webpage. I found VQFN for the ADS6442, but pinout is not the same. We have an EVM for the ADS8568, so I'm assuming the files exist, just need to be posted on the PF page:

Hi Leonard,

Most schematic capture/board layout programs have two separate libraries, one for schematic symbols and one for PWB footprints. Consider the case of a generic resistor - the schematic symbol stays the same regardless if its an 0402 or a 100W chassis mount.

For the ADS8568, you would create the schematic symbol and then associate it to the VQFN(RGC)64 footprint. We are working with the packaging folks to try and get better coverage, this is an on-going project. In the meantime, any VQFN(RGC)64 footprint you might find on the web site should accommodate every device in our portfolio that is in that package.

Yes, understand, that is why I sent them the ADS6442 package, but as it turns out, he needs the schematic symbol portion, not the footprint. He uses Altium, and would prefer we sent the file so he does not have to recreate it or induce any errors.

Since the ADS8568EVM-PDK uses this schematic symbol, could we please get this file? Thank you.

Hi Leonard,

Try this: http://webench.ti.com/cad/cad.cgi?partno=ADS8568, the top-level page is at http://webench.ti.com/cad/

The symbols aren't necessarily pretty, but will have the pin names, numbers, and electrical type. You can re-arrange the symbol as desired.
