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.

Hi, Ron Many thanks for sharing info and code for using AD along with arduino.

Hi Bill, Just wondering about not needing the while ad99850. It is important to note the scheduled dock date on the order entry screen. Leave a Reply Cancel reply Your email address will not be published.

The package for this IC i. He looked over everything. I can send you the schematic and the code if you want.

Since my last comment, I have received my AD boards and dafasheet it running on the bench in about 5 minutes! Hey Walt, thanks for commenting. Hi All, I am using the AD with a pic microcontroller for outputting a square and sine wave in the range of khz.

The steps are set with a second rotary encoder not interrupt-driven connected to ATmega pins A2 and A3.


I hope you can help me with this. I had it wired and running within a matter of minutes. Are there differences in quality of components in different batches of modules? I can email you the correct code upon request:. Therefore, I’ve limited the available frequency range from 10 Hz to 10 MHz in the software.

And sir now I want to connect a display with it, which will show the parameters related to the out-put waveform. My next iteration will move the constant calculation outside the main loop. ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. Model The model number is a specific version of a generic that can be purchased or sampled. One concern though is the current it takes, I measured mA under daasheet mW.

So this is very strange, I hooked everything up as indicated but cannot prove Ddatasheet have any output.

Hey Matt, datasheeet trimpot adjusts the duty cycle of the square wave output. Just cut and paste, and upload to your Arduino board. Any idea how I can turn off the AD!!! It was exactly what I needed. The unit will be used to power an ultrasonic transducer running at ad98500. I think it would be neat to use the with a LCD keypad shield and be able to just cursor over to the digit you want to change, hit up or down, and then select. This is just above the audio range so you can use almost any audio amplifier schematic maybe with some modifications.

D9 is a PWM pin so the display’s backlight brightness can be adjusted if desired. I’ve set it in software to ” -ie maximum brightness. Looks like yours will be the simplest. Pushing the rotary encoder’s button connected to D4 resets the frequency to 1 kHz. You code was the starting point! Hi, thanks for your great work, and sharing the code. I had to datashheet a plug-in so it would display correctly. And how should I will match the arduino with the display and please tell me about the code. I bought a few of the square blue boards and have been using them, everything seems fine.

I will also need to change the pulse width and pule frequency values through a rotary encoder. Do you have another Arduino to substitute?
