The AD9833 is a low power, programmable waveform generator. It consumes 12.65 mW of power, operates from a 2.3 V to 5.5 V supply, and can output 0 MHz to 12.5 MHz sinusoidal, triangular, and square waves. The AD9833 also features 28-bit resolution and a 3-wire SPI interface.
The AD9833 is a low‑power, digitally programmable waveform generator that operates from 2.3 V to 5.5 V and consumes only 12.65 mW at 3 V. It provides sine, triangular and square wave outputs, a 28‑bit frequency/phase resolution (0.1 Hz at 25 MHz reference), and is controlled via a 3‑wire SPI interface. The device is supplied in a 10‑lead MSOP package and is qualified for automotive use.
Typical applications include frequency‑stimulus generation, liquid and gas flow measurement, proximity and motion sensing, test and medical equipment, and time‑domain reflectometry. An evaluation board and system demonstration platform are available for rapid prototyping, and automotive‑grade parts are offered for rugged environments.
