Description

The AD9833BRMZ is a Direct Digital Synthesis (DDS) waveform generator that is designed and produced by Analog Devices. It is a low power, programmable waveform generator that is capable of producing sine, triangular, and square wave outputs. The waveform generation function is required in various types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable, allowing easy tuning, and no external components are needed.
