Description:

The AD9833 is a programmable waveform generator capable of generating sine, triangle, and square wave signals with a frequency range of 0-12.5MHz. The waveform generator is widely used in various measurements, excitations, and time-domain field determinations. The output frequency and phase can be set using easy-to-use software. When the main clock frequency is 25MHz, the accuracy is 0.1Hz, and at a main clock frequency of 1MHz, the accuracy can reach 0.004Hz. Data can be written via 3 serial interfaces.

Applications:

• Frequency excitation / waveform generation. Measurement of liquid and air flow.
• Sensitive applications - access, motion, failure detection.
• Linear loss, linear attenuation.
• Testing devices and other equipment.
• Scanning, clock generator.
