AD5930 programmable frequency sweep and output burst waveform generator is a frequency sweep/radar, network/impedance measurement, incremental frequency stimulus, sensory application, proximity and motion, BFSK frequency burst/pulse wave generator
The AD5930 is a waveform generator that provides programmable frequency sweep and burst capabilities. It features a 10‑bit DAC, up to 25 MHz output frequency, and can operate from a 2.3 V to 5.5 V supply while consuming as little as 20 pA in power‑down mode. The device supports multiple sweep modes, including triangular, saw‑tooth and single‑frequency burst, and is controlled via a 3‑wire serial interface.
The datasheet lists detailed specifications such as 50 MSPS update rate, 53 dB SNR, and 1.7 ms wake‑up time, and provides mechanical information for the 20‑lead pb‑free TSSOP package. Application areas include frequency‑sweeping radar, impedance measurement, BFSK, and motion sensing. Ordering information and an evaluation board reference are also included.
