GENERAL DESCRIPTION
The AD59301 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 analog or digital frequency-stepped waveforms. Because frequency profiles are preprogrammed, 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 8 mA, the AD5930 provides a convenient low power solution to waveform generation.
