Product Details

The AD5932 is a waveform generator providing a programmable frequency scan. Utilizing embedded digital processing allowing enhanced frequency control the device generates synthesized analog or digital frequency-stepped waveforms. Because frequency profiles are preprogrammed continuous write cycles are eliminated, thereby freeing up valuable DSP/µController resources. Waveforms start from a known phase and are incremented phase continuously allowing phase shifts to be easily determined.

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 the part stays at each frequency. The frequency profile can be initiated by toggling the CTRL pin.

A number of different scan profiles are offered. The user can choose to output the last frequency in the scan continuously, or can choose to return to midscale.

The AD5932 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 and has a standby function which allows sections of the device that are not being used to be powered down.

The AD5932 is available in a 16-pin TSSOP package.
