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.

datashset The various ranges specified are as follows: Once an order has been placed, Analog Devices, Inc. Transit times from these sites may vary. Package Description The package for this IC i. For detailed drawings and chemical composition please consult our Package Site.

The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors. The Circuit diagram included on the ebay auction had no resemblance to the device I got, but it seems the design is the same or similar to most of the barebone AD boards on ebay – just the chip, 30MHz crystal, header pins, bypass caps, and a low pass filter.

W34 must also be set. ADIsimDDS uses mathematical equations to model and illustrate the overall performance of the selected device. The performance is shown below. This can be one of 4 stages: 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 the 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 datadheet buffer to the control register as shown below from the datasheet:.

We do take orders for items that are not in stock, so delivery may be scheduled at a future date. Model The model number is a specific version of a generic that can be purchased or sampled.

That’s it for now – I might spend some more time looking at the output waveforms if I can find a use for ad98551 device. Model Package Pins Temp. Comparable Parts Click to see all in Parametric Search.

Let’s get serial UT The various ranges specified are as follows:. The product is appropriate for new designs but newer alternatives may exist. The Lowpass filter was calculated with RFSim As the lowpass allows frequencies of approx. Hardware, Software, Stuff I find Interesting. Even a second one can be daatsheet on it, as the user may assemble R7 OR R9 to distinguish between them.

This tool also models an estimate of the overall spectral performance, and allows the user to explore the effects of external reconstruction filters. Temperature Range This is the acceptable operating range of the device. Pin Count is the number of pins, balls, or pads on the device.

Please consult the datasheet for more information. When using version 1. Parallel or Serial Asynchronous Loading Format.

The AD contains a unique X6 reference clock multiplier circuit that obviates the datasehet for a high-speed reference oscillator. Full source of a SPI arduino sketch is here. In order to power it up! Please enter samples into your cart to check datashwet availability. Price Rohs Orders from Analog Devices. The device has 3 7-pin headers: When referenced to an accurate clock source, the AD generates a stable frequency and phase-programmable digitized analog output sinewave. Note, that the LSB is transmitted first!

It is important to note the scheduled dock date on the order entry screen.

For the crystal oscillator a separate voltage regulator is available, in order to generate different voltages necessary for different oscillator types. We use a crystal oscillator of MHz and do not use the internal multiplier in order to increase noise performance.

The package for this IC i. Buy a lot of crystals: As this board is intended to datashedt in the MHz-range, where monolithic amplifiers are demanding unpractical large inductors for biasing. I found the reset pin could be left tied low in these simple tests but i’d do an explicit hardware reset pulse in an application.

Sample availability may be better than production availability.
