Description
General part information
AD5930 Series
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/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.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.To program the device, the user enters the start frequency, the increment step size, the number of increments to be made, and the time interval that the part outputs each frequency. The frequency sweep profile is initiated, started, and executed by toggling the CTRL pin.A number of different sweep profiles are offered. Frequencies can be stepped in triangular-sweep mode, which continuously sweeps up and down through the frequency range. Alternatively, in saw-sweep mode, the frequency is swept up through the frequency range, but returns to the initial frequency before executing the sweep again. In addition, a single frequency or burst can be generated without any sweep.The AD5930 is written to via a 3-wire serial interface, which operates at clock rates up to 40 MHz. The device operates with a power supply from 2.3 V to 5.5 V. Note that AVDDand DVDDare independent of each other and can be operated from different voltages. The AD5930 also has a standby function, which allows sections of the device that are not being used to be powered down.The AD5930 is available in a 20-lead pb-free TSSOP package.ApplicationsFrequency sweeping/radarNetwork/impedance measurementsIncremental frequency stimulusSensory applicationsProximity and motionBFSKFrequency bursting/pulse trains
