GENERAL DESCRIPTION

The AD9833 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. 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 resolution.

The 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 V.

The AD9833 has a power-down function (SLEEP). This function

allows sections of the device that are not being used to be powered

down, thus minimizing the current consumption of the part. For

example, the DAC can be powered down when a clock output

is being generated.

The AD9833 is available in a 10-lead MSOP package.
