ADS1675 REF PCB

Other Parts Discussed in Thread: ADS1675

Hi,

We have just purchased the new ADS1675 REF board recently.

It is Rev B. Appreciate if any of you could upload the latest DDB files for Rev B please.

I am also using Altium Designer software. After conversion of the Protel files (for Rev A) downloaded from E2E forum, I noticed that the ground plane has some incomplete internal lines.

The whole plane is still AGND but I am curious about the purpose of those lines or is it due to incorrect conversion?

Thank you for your help.

Regards,

Jean

Hi Jean,

The ADS1675 REF version B database is attached. There were two pins on the ADS1675 that swapped - pins 21 and 22 - from the RevA to the RevB board. The ground layer was segmented to direct analog and digital return currents away from the sensitive nodes of the ADS1675.

Hi Tom,

Thank you for the files. They are now converted to Altium and I observed your comment regarding the swapped pins.

Thank you for the information, I understand better now.

Have a Happy New Year.
