AD9834 is a 20mW power, 2.3V to 5.5V power supply, 50MHz complete DDS chip. It has Narrow-band SFDR>72dB, 2.3V to 5.5V power supply, 50MHz reference clock, 0MHz to 25MHz output, sine output/triangular output, on-board comparator, 3-wire SPI® interface, extended temperature range (-40°C to +105°C), power-down option, 20mW power consumption, 3V, 20-Lead TSSOP package and other features.
The AD9834 is a 50 MHz low‑power Direct Digital Synthesis (DDS) device that generates high‑performance sine and triangular waveforms. It operates from a 2.3 V to 5.5 V supply, consumes only 20 mW at 3 V, and includes an on‑board comparator for square‑wave generation.
The document lists detailed electrical specifications, absolute maximum ratings, pin functions, typical performance curves, and ordering information. It also defines terminology such as SFDR, INL, and DNL, and explains the internal architecture of the NCO, phase modulator, SIN ROM, DAC, and comparator.
