Features:The AD9833 is a low power, programmable waveform generator capable of producing sine, triangular, and square wave outputs. Waveform generation is required in types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable, allowing easy tuning. No external components are needed. The frequency registers are 28 bits wide: with a 25 MHz clock rate, resolution of 0.1 Hz can be achieved; with a 1 MHz clock rate, the AD9833 can be tuned to 0.004 Hz resolutionThe AD9833 has a standard serial interface that allows the part to interface directly with microprocessors. The device uses an external serial clock to write the data or control information into the deviceThe AD9833WBRMZ-REEL model is available with controlled manufacturing to support the quality and reliability requirements of automotive applications. Note that this automotive model may have specifications that differ from the commercial models; therefore, designers should review the Specifications section of this data sheet carefully. Only the automotive grade product shown is available for use in automotive applications. Contact your local Analog Devices account representative for product ordering information and to obtain the Automotive Reliability reports for these modelsThe AD9833 is written to via a 3-wire serial interface. This serial interface operates at clock rates up to 40 MHz and is compatible with DSP and microcontroller standards. The device operates with a power supply from 2.3 V to 5.5 VThe AD9833 has a power-down function (SLEEP). This allows sections of the device that are not being used to be powered down, thus minimizing the current consumption of the part, e.g., the DAC can be powered down when a clock output is being generatedSpecifications: Digitally programmable frequency and phase12.65 mW power consumption at 3 V0 MHz to 12.5 MHz output frequency range28-bit resolution: 0.1 Hz at 25 MHz reference clockSinusoidal, triangular, and square wave outputs2.3 V to 5.5 V power supplyNo external components required3-wire SPI interfaceExtended temperature range: 40C to +105CPower-down option Update Rate: 25(max)VOUT Maximum: 0.65VVOUT Minimum: 38mVVOUT Temperature Coefficient: 200Input High Voltage 1.7-2.8VInput Low Voltage: 0.5-0.7VInput Current: 10AInput Capacitance: 3pFOperating temperature range is 40C to +105C; typical specifications are at 25CSize: 17*12mm\/0.66*0.47\"Color: blue; Material: plastic Package Included:1 x Signal Generator Module1 x pinOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
