AD datasheet, AD pdf, AD data sheet, datasheet, data sheet, pdf, Analog Devices, MHz Complete DDS synthesizer. modules is the Analog Devices AD DDS waveform generator. An Internet Web Figure 1 Sin(x)/x envelope from the AD datasheet. AD datasheet. From this figure it is easy to see that as the output frequency increases the first system image and the output frequency.

Temperature Range This is the acceptable operating range of the device. At least one model within this product family is in production and available for purchase.

Daatasheet Description The package for this IC i.

Rectification Power Supply Designer: Pin Dataseet Pin Count is the number of pins, balls, or pads on the device. In case you use the internal clock-multiplier, W32 Bit 0 of Word 0 must be set. Anyway, we used a MHz oscillator because it was in our treasure box and the filter has a maximum attenuation at about MHz. Model Package Pins Temp. Model The model number is a specific version of a generic that can be purchased or sampled.

For volume-specific price or delivery quotes, please contact your local Analog Devices, Inc. In serial mode the chip can be controlled with only 3 pins plus VCC and GNDbasically a bit from the control word is written to aad9851 DATA pin, W CLK is pulsed high until all 40 bits have been sent and then FQ UD is pulsed high to transfer the 40 bits from a buffer to the control register as shown below from the datasheet:.


The package for this IC i.

Status Status indicates the current lifecycle of the product. The performance is shown below. If a model is not available for web samples, look for notes on the product page that indicate how to request samples or Contact ADI.

Even a second one can be plugged on it, as the user may assemble R7 OR R9 to distinguish between them. Pricing displayed for Evaluation Boards and Kits is based on 1-piece pricing.

Product Lifecycle Production At least one model within this product family is in production and available for purchase. The Dtaasheet button will be displayed if a model is available for web samples. For the crystal oscillator a separate voltage regulator is available, in order to generate different voltages necessary for different oscillator types.

Let’s get serial UT Click here to be the first to Comment Auto Refresh: We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. The Purchase button will be displayed if model is available dattasheet purchase online at Analog Devices or one of our authorized distributors. W34 must datzsheet be set. We therefore decided to try to get away with an opamp.

Other models listed datasehet the table may still be available if they have a status that is not obsolete. This is the acceptable operating range of the device.


The AD’s innovative high-speed DDS core provides a bit frequency tuning word, which results in an output tuning resolution of 40 milli-Hertz, for a MHz reference clock. The model is currently being produced, and generally available for purchase and sampling. Also, please note the warehouse location for the product ordered.

Because the ‘frequency tuning word’ is a 32 bit integer, when it is a9d851 by 1 the sine wave increases by. That’s it for now – I might spend some more time looking at the output waveforms if I can find a use for the device. When using version 1.

The product is appropriate for new designs but newer alternatives may exist. Vatasheet Parts Click to see all in Parametric Search. Transit times from these sites may vary. Select the purchase button to display inventory availability and online purchase options.

As the lowpass allows frequencies of approx. ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. Please Select a Region.

We use a crystal oscillator of MHz and do not use the internal multiplier in order to increase noise performance. The programming of this “simple” dds is quite easy. Ad981 of Analog Devices. Please consult the datasheet for more information.

The specific part is obsolete and no longer available. The device has 3 7-pin headers:
