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.

Please enter samples into your cart to check sample availability. I am very frustrated!
Product Lifecycle Production At least one model within this product family is in production and available for purchase. Didn’t find dattasheet you were looking for? The parallel load format consists of five iterative loads of an 8-bit control datawheet byte. In other words, would it be worthwhile buying one or two more from different suppliers? Orient the board so that the pot is on the right, the OSC on the left. Just wanted to say thanks for the sketch!
A9850 digital pins 8 through 11, proto shield installed on the UNO. One other interesting piece of information — when I power up the AD, I get 1.
What I also did was to remove the updating of the frequency from the Loop.
Its really very weak. One concern though is the current it takes, I measured mA under 5V mW. On some other version of similar module, for dtasheet, http: N8RO did an excellent job. Did you mean speck as in piece of dirt or spec as in an inability of the Arduino to work correctly because of specification?

This sine wave can be used directly as a datashwet source or converted to a square wave for agile-clock generator applications. This can be one of 4 stages: An interrupt-driven rotary encoder, connected to the ATmega interrupt pins D2 and D3adjusts ad98550 frequency between 10 Hz and 10 MHz in pre-set steps. You can interface to the board via your computers serial or parallel port, but as a recent Arduino convert, I decided to go that route.
I think it would be neat to use the with datadheet LCD keypad shield and be able to just cursor over to the digit you want to change, hit up or down, and then select.
Your code is compiling and working great. It must be something obvious, but what?
Does it support that much memory and how long does it take to transfer that data? There was a speck of dirt or metal on his Arduino, making it inoperable. I borrowed your code and testited mine …. Is this possible when using AD There may be a small difference between the tuning word calculated by this program and the tool you mentioned, but it will only be in the least significant bits and is simply due to differences in the way rounding to the nearest integer is done.
Also, please note the warehouse location for the product ordered.
First check the crystal oscillator. Hey Matt, the trimpot adjusts the duty cycle of the square wave output. This is the best single channel DDS program that I have found. I tried to write: Here is a post I made about it and another toy I got. Mine are the narrow green board style. The steps are set with a second rotary encoder not interrupt-driven connected to ATmega pins A2 and A3.
Note that I have changed the four Arduino data port freq control pins of the AD module so that the 8 keypad ports could all be contiguous: 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: Hi NR8O thanks a lot for your code.
These modules are supposed to get up to 30 MHz and some claim 40 MHz.
It is important to note the scheduled dock date on the order entry screen. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board.
Thanks for your help! This is the date Analog Devices, Inc. Pretty impressive little board.
