The AD9837 is a low power, programmable waveform generatorcapable of producing sine, triangular, and square wave outputs.Waveform generation is required in various types of sensing,actuation, and time domain reflectometry (TDR) applications. The outputfrequency and phase are software programmable, allowing easytuning. The frequency registers are 28 bits: with a 16 MHz clock rate, resolution of 0.06 Hz can be achieved; with a 5 MHz clock rate, the AD9837can be tuned to 0.02 Hz resolution.The AD9837 is written to via a 3-wire serial interface. This serialinterface operates at clock rates up to 40 MHz and is compatiblewith DSP and microcontroller standards. The device operateswith a power supply from 2.3 V to 5.5 V.The AD9837 has a power-down (SLEEP) function. Sections of the device that are not being used can be powered down to minimize the current consumption of the part. For example, the DAC can be powered down when a clock output is being generated.The AD9837 is available in a 10-lead LFCSP_WD package.APPLICATIONS Frequency stimulus/waveform generation Liquid and gas flow measurement Sensory applications: proximity, motion, and defect detection Line loss/attenuation Test and medical equipment Sweep/clock generators Time domain reflectometry (TDR) applications
