AD9834BRUZ Description

Short technical summary and product information.

The AD9834BRUZ is a low power, 75 MHz complete Direct Digital Synthesizer (DDS) from Analog Devices. It provides high performance sine and triangular outputs, and includes an on-board comparator for square wave generation. The device is capable of frequency and phase modulation, with 28-bit frequency registers providing 0.28 Hz resolution at 75 MHz clock. The output frequency can reach up to 37.5 MHz. The narrow-band SFDR is >72 dB.

 

The AD9834 operates from a 2.3V to 5.5V supply and consumes only 20 mW typical at 3V. The 3-wire SPI interface simplifies connection to microcontrollers and DSPs. The extended temperature range of -40°C to +105°C makes it suitable for industrial applications. The device is available in a 20-lead TSSOP (20-TSSOP) package for surface mount assembly.

 

Typical applications include frequency stimulus/waveform generation, frequency phase tuning, low power RF/communications systems, liquid and gas flow measurement, and sensory applications.
