The AD5930 is a programmable frequency sweep and output burst waveform generator. It features a 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, power supply: 2.3 V to 5.5 V, automotive temperature range: −40°C to +125°C, 20-lead pb-free TSSOP. It is suitable for frequency sweeping/radar, network/impedance measurements, incremental frequency stimulus, sensory applications, proximity and motion, BFSK frequency bursting/pulse trains, etc.
The AD5930 from Analog Devices is a waveform generator that provides programmable frequency‑sweep and burst capabilities. It features a 10‑bit DAC, selectable sinusoidal, triangular, and square wave outputs, and can be controlled via a 3‑wire serial interface. The device operates from a 2.3 V to 5.5 V supply and includes a low‑power standby mode.
The datasheet lists detailed specifications such as a 25 MHz maximum output frequency, 50 MSPS update rate, and a power‑down current of 20 pA. It also provides timing characteristics, absolute maximum ratings, and package information (20‑lead pb‑free TSSOP). Applications include frequency‑sweeping radar, impedance measurements, and BFSK signaling.
