AD5930YRUZ

AD5930 is a waveform generator with programmable frequency sweep and output burst capability. Utilizing embedded digital processing that allows enhanced frequency control, the device generates synthesized analogue or digital frequency-stepped waveforms. Because frequency profiles are pre-programmed, continuous write cycles are eliminated and thereby free up valuable DSP/microcontroller resources. Waveforms start from a known phase and are incremented phase continuously, which allows phase shifts to be easily determined. Consuming only 8mA, this device provides a convenient low power solution to waveform generation. It is used in applications such as frequency sweeping/radar, network/impedance measurements, incremental frequency stimulus, sensory applications, proximity and motion, BFSK, frequency bursting/pulse trains.
