00 — Overview

What the AD9833 does

The AD9833 is a low power, programmable waveform generator producing sine, triangular, and square wave outputs. It spans variants like the AD9833BRMZ and AD9833WBRMZ, operating across commercial, industrial, and automotive temperature ranges. Key parameters include 12.65 mW power consumption, a 0 MHz to 12.5 MHz output frequency range, 28-bit resolution, and a 2.3 V to 5.5 V power supply. The device requires no external components and features a 3-wire SPI interface. It is typically used for frequency stimulus, waveform generation, liquid and gas flow measurement, sensory applications, and time domain reflectometry.
