The Waveform Click is a precise sine/triangle/square waveform generator. It is capable of reproducing frequencies up to 12MHz. The Click board™ 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 very few 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.
The already mentioned waveform generator IC, AD9833, is the main component of the Waveform click. It is a low-power, programmable waveform generator, produced by Analog Devices. The AD9833, along with the AD5227, a digital potentiometer IC from the same company is controlled over the SPI interface, allowing both the frequency and the amplitude to be changed very quickly, without additional latency.
