Features:The AD9833 is a low power programmablewaveform generator capable of producing sine, triangular, and square waveoutputs. Waveform generation is required in various types of sensing, actuation,and time domain reflectometry applications. The output frequency and phase aresoftware programmable, allowing easy tuning. No external components are needed. The frequency registers are 28 bits; with a 25 MHz clock rate, resolution of0.1 Hz can be achieved. Similarly, with a 1 MHz clock rate, the AD9833 can betuned to 0.004 Hz resolution. The AD9833 is written to via a 3-wire serialinterface. This serial interface operates at clock rates up to 40 MHz and iscompatible with microcontroller standards. The device operates with apower supply from 2.3 V to 5.5 V. The AD9833 has a power-down function (SLEEP).This allows sections of the device that are not being used to be powered down, thusminimizing the current consumption of the part, e.g., the DAC can be powereddown when a clock output is being generated.The AD9833 is available in a10-lead MSOP package.Digitally programmable frequency and phase.Applicable to frequencystimulus/waveform generation, liquid and gas flow measurement, sensoryapplications--proximity, motion, and defect, detection, line loss/attenuation,test and medical equipment, sweep/clock generators, TDR.Specifications:Power Supply: 2.3V to 5.5V (typical 3.3V, 5V)Power Consumption: 20mW at 3 VOutput Frequency Range: 0MHz to 12.5MHz28-Bit Resolution: 0.1 Hz @ 25 MHz Ref ClockWave Output: Sinusoidal/Triangular/Square Extended Temperature Range: -40 to +105Package Includes:1 x DDS Signal Generator
