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.
