Programmable Frequency Scan Waveform Generator AD5932 FEATURES GENERAL DESCRIPTION Programmable frequency profile The AD59321 is a waveform generator offering a programmable No external components necessary frequency scan. Utilizing embedded digital processing that Output frequency up to 25 MHz allows enhanced frequency control, the device generates Burst-and-listen capability synthesized analog or digital frequency-stepped waveforms. Preprogrammable frequency profile minimizes number of Because frequency profiles are preprogrammed, continuous DSP/microcontroller writes write cycles are eliminated, thereby freeing up valuable Sinusoidal/triangular/square wave outputs DSP/microcontroller resources. Waveforms start from a known Automatic or single pin control of frequency stepping phase and are incremented phase-continuously, which allows Power-down mode: 20 A phase shifts to be easily determined. Consuming only 6.7 mA, Power supply: 2.3 V to 5.5 V the AD5932 provides a convenient low power solution to Automotive temperature range: -40°C to +125°C waveform generation. 16-lead, Pb-free TSSOP The AD5932 outputs each frequency in the range of interest for APPLICATIONS a defined length of time and then steps to the next frequency in Frequency scanning/radar the scan range. The length of time the device outputs a particular Network/impedance measurements frequency is preprogrammed, and the device increments the Incremental frequency stimulus frequency automatically; or, alternatively, the frequency is Sensory applications incremented externally via the CTRL pin. At the end of the Proximity and motion range, the AD5932 continues to output the last frequency until the device is reset. The AD5932 also offers a digital output via the MSBOUT pin.
