Part Details:

a Low Power 20 mW 2.3 V to 5.5 V Programmable Waveform Generator AD9833 FEATURES GENERAL DESCRIPTION Digitally Programmable Frequency and Phase The AD9833 is a low power programmable waveform generator 20 mW Power Consumption at 3 V capable of producing sine, triangular, and square wave outputs. 0 MHz to 12.5 MHz Output Frequency Range Waveform generation is required in various types of sensing, 28-Bit Resolution (0.1 Hz @ 25 MHz Ref Clock) actuation, and time domain reflectometry applications. The output Sinusoidal/Triangular/Square Wave Outputs frequency and phase are software programmable, allowing easy 2.3 V to 5.5 V Power Supply tuning. No external components are needed. The frequency regis- No External Components Required ters are 28 bits; with a 25 MHz clock rate, resolution of 0.1 Hz 3-Wire SPI® Interface can be achieved. Similarly, with a 1 MHz clock rate, the AD9833 Extended Temperature Range: ­40 C to +105 C can be tuned to 0.004 Hz resolution. Power-Down Option The AD9833 is written to via a 3-wire serial interface. This serial 10-Lead MSOP Package interface operates at clock rates up to 40 MHz and is compatiblewith DSP and microcontroller standards. The device operates APPLICATIONS with a power supply from 2.3 V to 5.5 V. Frequency Stimulus/Waveform Generation The AD9833 has a power-down function (SLEEP). This allows Liquid and Gas Flow Measurement sections of the device that are not being used to be powered down, Sensory Applications--Proximity, Motion, and Defect thus minimizing the current consumption of the part, e.g., the DAC Detection can be powered down when a clock output is being generated. Line Loss/Attenuation The AD9833 is available in a 10-lead MSOP package.
