The Waveform Click Board™ is a precise sine/triangle/square waveform generator, capable of reproducing frequencies up to 12MHz. It utilizes a Direct Digital Synthesis (DDS) IC made by Analog Devices, a company famed for its specialization in DSP development and engineering. The AD9833 waveform generator IC requires a very low count of additional components: besides the external clock source, it requires almost no components, allowing the Click Board™ to be equipped with some additional circuits. A digital potentiometer IC is used to attenuate the output signal, while the high-quality op-amp is used as a buffer.
