Features:
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 applications.
The output frequency and phase are
software programmable, allowing easy tuning. No external components are needed.
The frequency registers are 28 bits; with a 25 MHz clock rate, resolution of
0.1 Hz can be achieved. Similarly, with a 1 MHz clock rate, the AD9833 can be
tuned to 0.004 Hz resolution.
The AD9833 is written to via a 3wire serial
interface. This serial interface operates at clock rates up to 40 MHz and is
compatible with microcontroller standards. The device operates with a
power supply from 2.3 V to 5.5 V.
The AD9833 has a powerdown function (SLEEP).
This allows sections of the device that are not being used to be powered down, thus
minimizing the current consumption of the part, e.g., the DAC can be powered
down when a clock output is being generated.
The AD9833 is available in a
10 MSOP package.
Digitally programmable frequency and phase.
