Programmable Frequency Sweep and  
Output Burst Waveform Generator  
AD5930  
FEATURES  
GENERAL DESCRIPTION  
Programmable frequency profile  
No external components necessary  
Output frequency up to 25 MHz  
Burst and listen capability  
Preprogrammable frequency profile minimizes number of  
DSP/µcontroller writes  
Sinusoidal/triangular/square wave outputs  
Automatic or single pin control of frequency stepping  
Waveform starts at known phase  
Increments at 0° phase or phase continuously  
Power-down mode: 20 µA

The 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 analog or digital  
frequency-stepped waveforms. Because frequency profiles  
are preprogrammed, continuous write cycles are eliminated  
and thereby free up valuable DSP/µcontroller 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.  
Power supply: 2.3 V to 5.5 V  
The AD5930 can be operated in a variety of modes. In  
continuous output mode, the device outputs the required  
frequency for a defined length of time and then steps to the  
next frequency. The length of time the device outputs a  
particular frequency is either preprogrammed and the device  
increments the frequency automatically, or, alternatively, is  
incremented externally via the CTRL pin. In burst mode, the  
device outputs its frequency for a length of time and then  
returns to midscale for a further predefined length of time  
before stepping to the next frequency. When the MSBOUT pin  
is enabled, a digital output is generated.  
Automotive temperature range: −40°C to +125°C
