In this case, the DAC is not required and can be powered down to reduce power consumption. The parts of the chip that can be powered down are the internal clock and the DAC. The AD is also suitable for signal generator applications. To load the remaining eight bits to the AD, P3. RESET does not affect any of the addressable registers. Sections of the device that are not being used can satasheet powered down to minimize the current consumption.

International prices may differ due to local duties, taxes, fees and exchange rates. This pin is used for decoupling the DAC bias voltage. The different functions and the various output options from the AD are described in more detail in the Frequency and Phase Registers section.

Examples of this are shown in Table 12 and Table Clock feedthrough refers to the magnitude of the MCLK signal relative to the fundamental frequency in the output spectrum of the AD It also has an on-board comparator that allows a square wave to datashheet produced for clock generation.

Data is loaded into the device as a bit word under the control of a serial clock input SCLK. Temperature Range This is the acceptable operating range of the device.

Avoid crossover of digital and analog signals.

20 mW Power, 2.3 V to 5.5 V, AD9834 Data Sheet

Fast switching signals, such as clocks, should be shielded fatasheet digital ground to avoid radiating noise to other sections of the board. A minimum etch technique is generally best for ground planes because it gives the best shielding. View Detailed Evaluation Kit Information.

Consuming only 20 mW of power at 3 V makes the AD an ideal candidate for power-sensitive applications. Output Compliance The output compliance refers to the maximum voltage that can be generated at the output of the DAC to meet the specifications. When the AD is powered up, qd9834 part should be reset.

One of the areas where the AD is suitable is in modulation applications. These registers contain invalid data, and, therefore, should be set to a known value by the user. If DVDD is equal to or less than 2. This is available on the Analog Devices website.

The bit serial data-word is applied to this input. Sample availability may be better than production availability. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors. The available outputs are a sinusoidal output or a triangle output. Functions that select frequency and phase registers, reset internal registers, and power down the DAC can be implemented using either software or hardware.

Because datasueet the various output options available from the part, the AD can be configured to suit a wide variety of applications.

The DAC produces bit linear triangular function. Each of these subcircuits is discussed in the Circuit Description section.

This control bit allows the user to continuously load the MSBs datasheeh LSBs of a frequency register ignoring the remaining 14 bits. Please enter samples into your cart to check sample availability.
