Working Principles

AD9838BCPZ-RL7 utilizes a direct digital synthesis (DDS) technique to generate waveforms. It consists of a phase accumulator, a sine look-up table, and a digital-to-analog converter (DAC). The phase accumulator generates a digital representation of the desired waveform, which is then converted into an analog signal by the DAC. The resulting analog signal is filtered and amplified to obtain the desired waveform.
