AD9850 DDS Signal Generator Module

AD9850 DDS Signal Generator Module is equipped with an AD9850 IC, a powerful Oscillator of 125MHz, and a DSS synthesizer. It operates at a very low power supply, thus finding applications in many small self-assembly projects to produce square and sine waves.

The AD9850 Signal Generator Module consists of the following components:

Crystal Oscillator: The module contains a crystal oscillator to provide clock and timing control for the Integrated Circuit.
Duty Cycle or Amplitude Adjustment: The module is provided to adjust the signals' offset and pulse widths through the in-built potentiometer.
AD9850 IC: This integrated circuitry does all the processing. With the help of a powerful Oscillator and other components, it can output analog signal waves.
