It’s commonly used to generate sine, triangle, and square waveforms with frequency and phase control. The AD9833 contains a 16-bit control register that sets up the AD9833 as the user wants to operate it. In this post covid world, I seem to be just waiting on parts half the time, if I can even find them in stock. The AD9833 is a cool little IC, which can generate sine, square and triangle waves with frequency up to 10Mhz (although at such frequency the output seems to be quite distorted) and those parameters can be set from an Turn up the gain knob to turn on the function generator. It can be used with a supply voltage of 2. Supports hardware SPI and software SPI. Direct Digital Synthesis (DDS) Direct digital synthesis (DDS) is a method of producing an analog waveform—usually a sine wave—by generating a time-varying signal in digital form and then performing a digital-to-analog conversion.
