AD9959 PCB Footprint Import for ExpressPCB Layout - Tips and Resources

[Jdo300]

Hello All,

I'm working on a PCB layout in ExpressPCB and I am trying to make a footprint for the AD9959 chip.

I went to this page here on Analog Devices' page to get a suitible pcb footprint but they don't have any formats that I can import into ExpressPCB: http://www.analog.com/en/SymbolsAndFootprints/0,3152,AD9959,00.html

Originally, I was just going to take the measurements from the datasheet to make the pads but I'm not sure how big the heat pad should be or of some of the exact dimensions for the positioning of the pads. I figured it would be safest to just import one that was already designed to minimize the possability of any issues later.

Do any of you know of any CP-56 footprints that I can look to for reference dimensions or one that can be imported into ExpressPCB?

Thanks,
Jason O

Ok, nevermind. I managed to make the footprint from the measurements in the datasheet. Here is a copy of it in case anyone else out there may want to use it.

Hi Jason,

Thank you for reaching out and sharing your experience with creating a footprint for the AD9959 chip in ExpressPCB. I understand that it can be challenging to create a precise footprint without the proper resources and dimensions.

I did some research and found a few tips and resources that may be helpful to you. First, I would recommend checking out the ExpressPCB website for any available tutorials or guides on creating custom footprints. They may also have a library of existing footprints that you can use for reference or import.

Additionally, I found a forum thread on the ExpressPCB website where users have shared their experiences and tips for creating footprints for specific chips, including the AD9959. You may find some helpful information and resources there: https://www.expresspcb.com/expresspcb-forum/topic/creating-a-footprint-for-the-ad9959-chip/.

Another option is to reach out to Analog Devices directly and inquire about any available ExpressPCB footprints for the AD9959 chip. They may also be able to provide you with the precise dimensions and specifications for the heat pad.

I hope these suggestions help and you are able to successfully create your footprint for the AD9959 chip in ExpressPCB. Good luck!
