An Evaluation Board is a board engineered to datasheft the performance of the model, the part is included on the board. Liquid and gas flow measurement. Temperature ranges may vary by model. ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device.

Resistor and capacitor values are straight out of a datasheet schematics. The AD is a numerically-controlled oscillator employing. Similar DDS products can be found at http: Comparable Parts Click to see all in Parametric Search. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. Although the chip is designed for RF applications, it makes a good audio frequency sinewave generator, too. Lines 20 to 50 contain the initialization code, after that the output frequency is set to Hz, and chip is taken out of a reset which enables the output.


I then stuck a wire into socket through the board, soldered and trimmed the wire. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors. Clock rates of up to 50 MHz are supported.

Complete DDS With 10-Bit On-Chip DAC

On-chip COS lookup table. Clearly, some sort of low-pass filtering is required to cut down the higher harmonics, and noise. Finally I soldered power supply decoupling caps directly to the converter board. Modulation is effected by loading registers through the serial interface. Do filter the AVDD power supply, and a9d835 the analog and digital grounds separated, connect them in single point as close to power supply as possible.

Please Select a Language. Frequency dataseet can be controlled to one part in 4 billion. Can be used to evaluation the AD also. If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup. Simple Circuit Controls Stepper Motors. I then scraped the pads off from where the TTSOP case needed to go, and soldered wires to datashedt terminals from each of the pins. International prices may differ due to local duties, taxes, fees and exchange rates.

This is the acceptable operating range of the device.

Below are the scope captures of output signal at 30kHz and khz. Temperature Range This is the acceptable operating range of the device. At line is a subroutine that calculates a bit frequency word for a frequency given in variable F. The various ranges specified are as follows: After you have soldered and visually examined the format converter, measure resistance from each pin against its neighbors to find any possible shorts. Transit times from these sites may vary.
