AD5932YRUZ

AD5932 is a waveform generator offering a programmable frequency scan. Utilizing embedded digital processing that allows enhanced frequency control, the device generates synthesized analogue or digital frequency-stepped waveforms. Because frequency profiles are preprogrammed, continuous write cycles are eliminated, thereby freeing up valuable DSP/microcontroller resources. Waveforms start from a known phase and are incremented phase-continuously, which allows phase shifts to be easily determined. Application includes frequency scanning/radar, network /impedance measurements, incremental frequency stimulus, sensory applications, and proximity and motion.
