GENERAL DESCRIPTION

The AD59321 is a waveform generator offering a programmable frequency scan. Utilizing embedded digital processing that allows enhanced frequency control, the device generates synthesized analog 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. Consuming only 6.7 mA, the AD5932 provides a convenient low power solution to waveform generation.
