  • The AD9833 is a low power, programmable, sinusoidal waveform generator that needs to be generated in various types of waveform detection, implementation, and time domain reflectometry (TDR) applications.
  • The output frequency and phase are programmable software that can be easily adjusted. No external components are necessary. The frequency register is 28 bits wide: the clock frequency is 25 MHz, which can achieve a resolution of 0.1 Hz; the AD9833 has a clock frequency of 1 MHz and can be tuned to a resolution of 0.004 Hz.
  • Write via serial interface line. The serial interface operates at clock frequencies up to 40 MHz and is compatible with DSP and microcontroller standards. The device operates from a 2.3 V 5.5 V supply.
  • With power down function (SLEEP). This allows the unused portion of the device to be turned off, thereby minimizing the power consumption portion, for example, turning off the DAC when the output clock is generated.
  • A standard serial interface allows the device to be directly connected to different microprocessors. The device uses an external serial clock to write data or information to the control device.

Good quality, affordable price. Sine wave up to 2 MHz is generated well.

Works for me. I was able to get this to work using an available Arduino library for it, and got the sine wave output I was looking for.
