20-lead pb-free TSSOP 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. …
