For detailed drawings and chemical composition please consult our Package Site. This is how I usually do ac9835. No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. Model The model number is a specific version of a generic that can be purchased or sampled.

This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters. Although the 30kHz signal shows no such steps, they are still there, but as there are 10 times more discrete steps, they are also 10 times smaller. Frequency accuracy can be controlled to one part in 4 billion. On-chip COS lookup table. At line is a subroutine that calculates a bit frequency word for a frequency given in variable F.

Complete DDS With 10-Bit On-Chip DAC

An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board. Ask The Application Engineer— The circuit is quite straightforward. The model has not been released to general production, but samples may be available. Not to mention a loss of your hard-to-get chip. A power-down bit allows the user to power down the AD when it is not in darasheet the power consumption reduces to 1.

However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties that may result from its use. After you have soldered and visually examined the format converter, measure resistance from each pin against its neighbors to find any possible shorts.

Temperature Range This is the acceptable operating range of the device. Status Status indicates the current lifecycle of the product.

The model has been scheduled for obsolescence, but may still be purchased for a limited time. Clock rates of up to 50 MHz are supported. Similar DDS products can be found at. Modu- lation capabilities are provided for phase modulation and frequency modulation. Model Package Pins Temp. Modu-lation capabilities are provided for phase modulation and dayasheet modulation.


For more information about lead-free parts, please consult our Pb Lead free information page. You may want to check out the rfgenerator project for more modern version of the chip, and using it with AVR microcontroller. I then scraped the pads off from where the TTSOP case needed to go, and soldered wires to ‘dip24’ terminals from each of the pins.

Modulation is effected by loading registers through the serial interface. As you can see, the code is not a rocket science either. The model is currently being produced, and generally available for purchase and sampling. International prices may vary due to local duties, taxes, fees and exchange rates.

Temperature ranges may vary by model. Please Select a Language. All the magic smoke comes instantly out of a chip, and you have to start datxsheet over. Phase and frequency selector pins are not used in this application, so they are tied to ground. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors.
