![]() ![]() Sine wave is most commonly known as waveform for Alternating Current. Fred Schechter liked The Curious Case of (Swatch?)

Another reason to use modules these days is that the modules are often in-stock but the chips are unobtainable. ![]() This approach is great for one-off builds or as a proof-of-concept test bed that can later be spun onto a custom PCB. This is a good example of combining off-the-shelf modules to quickly build a project. We like the confidence that displays by sketching the initial circuit diagram with a ball-point pen - check out the sketch and the final pictorial schematic in the video below the break. The remaining specifications are met by the inherent characteristics of the DDS system, and the scriptable interface is accomplished with an Arduino controlling the AD9833 chips and two programmable gain amplifiers ( MCP6S31). He synchronizes the generators by disconnecting the reference crystal on the second module and driving it from the first one. uses AD9833 modules from the usual online vendors for a few dollars each. If you’ve ever rolled your own DDS using discrete ICs or in an FPGA, you can appreciate the benefit of squeezing the phase accumulator, sine lookup table, DAC, and control logic all into a single ten-pin package. The heart of the project is the Analog Devices AD9833, a complete Direct Digital Synthesis (DDS) waveform generator system on a chip. Frequency, Amplitude, and Phase control.Other than low-cost, his list of requirements was as follows: Microcontroller addict decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. ![]()
