The AD59321 is a programmable frequency scan waveform generator from AD company. It uses embedded digital processing to achieve enhanced frequency control. The device generates synthesized analog or digital frequency-stepped waveforms. Since frequency profiles are preprogrammed, continuous write cycles are eliminated, thereby freeing up valuable DSP/microcontroller resources. Waveforms start from a known phase and are incremented phase-continuously, which allows phase shifts to be easily determined. AD5932 consumes only 6.7 mA, providing a convenient low power solution to waveform generation. No external components are required. The output frequency is up to 25 MHz. Burst-and-listen capability. Pre-programmed frequency scan profiles can be used to create arbitrary frequency sweeps from 1 Hz to 25 MHz.
The AD5932 is a programmable frequency‑scan waveform generator that can output sinusoidal, triangular, or square waves up to 25 MHz without external components. It supports burst‑and‑listen operation, automatic or pin‑controlled frequency stepping, and a low‑power mode drawing only 6.7 mA.
The datasheet provides full electrical specifications, timing diagrams, absolute maximum ratings, and recommended test circuits. It also lists typical applications such as frequency scanning, radar, impedance measurement, and motion sensing, and includes mechanical details like the 16‑lead Pb‑free TSSOP package.
