AD Direct Digital Synthesis Modules. The circuit is taken directly from the example in the AD datasheet. and uses a MHz clock and a 40MHz output. Part Number: AD, Maunfacturer: Analog Devices, Part Family: AD, File type: PDF, Document: Datasheet – semiconductor. Introduction. This module described here is based on ADS, a CMOS, MHz, and Complete DDS. Synthesizer. The AD is a highly integrated device.

You can interface to the board via your computers serial or parallel port, but as datasheey recent Arduino convert, I decided to go that route. Thank you very much, I also managed to have the DDS up and running in 5 minutes, an essential starting point.
No matter what I tried, I could not get this to work. Details including my translation of your code on my blog: The AD also contains a high speed comparator that can be configured to accept the externally filtered output of the DAC to generate a low jitter square wave output.
Thanks Gerald for the answer.
I got the same problem with the program and the analog website. I’ve set it in software to ” -ie maximum brightness. I will xd9850 appreciate if anyone can confirm or otherwise what I think is happening.
How tight is the output sine at low e. International prices may differ due to local duties, taxes, fees and exchange rates.
All help will be greatly appreciated. Thanks to all of those who posted fatasheet data. I will also need to change the pulse width and pule frequency values through a rotary encoder.
Hi, Ron Many thanks for sharing info and code for using AD along with arduino. The routine is given the required frequency Fout and finds delta Phase, the datasheet equation tells you what Fout will be for a given delta Phase:.
I have a question, if you please. An even more clever pin assignment reduces the shield wiring a a mere few wires, where the socket J1 for the keypad solders directly into D0—D7.
Mine are the narrow green board style. This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters.
I have got the sine wave successfully but am failed to get the square wave output.
Notify me of follow-up comments by email. I think a download of the sketch would solve the problem. Pin Count is the number of pins, balls, or pads on the device. Notify me of new posts by email. First check the crystal oscillator.
Testing an eBay AD DDS module with Arduino Uno | NR8O
I am new with Arduino and new with DDS. I want degrees. You should now be able to copy and past the code and it will compile correctly. This is the date Analog Devices, Inc. Package Description The package for this IC i. Didn’t find what you were looking for? In the second version above Fatasheet changed the documentation but not the actual port assignment. Anyway, If what I am saying is correct then I will be contacting the supplier for the replacement of the module. The Year of the Waveform Generator.
This can be one of 4 stages: The adjustment of the blue pot is very delicate. I have at least 1 says 3. Hi Ron, Thanks for the post. Ugly at best, even after a decent filter…. ADI has always placed the highest emphasis dataeheet delivering products that meet ad985 maximum levels of quality and reliability.
