AD9837:  Low Power, 8.5 mW, 2.3 V to 5.5 V, Programmable Waveform Generator

Product Details

Product Status:Recommended for New Designs

The AD9837 is a low power, programmable waveform generator capable 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 output frequency and phase are software programmable, allowing easy tuning. 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 AD9837 can be tuned to 0.02 Hz resolution.

The AD9837 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 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.

Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
This month we conclude our two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.
