AD9835BRUZ-REEL

Overview

The AD9835BRUZ-REEL is a Direct Digital Synthesis (DDS) integrated circuit manufactured by Analog Devices Inc. It operates as a numerically controlled oscillator with a 10-bit resolution and supports clock frequencies up to 50 MHz. The device features a 28-bit frequency tuning word width and functions within a supply voltage range of 4.75 V to 5.25 V. It is housed in a 16-lead TSSOP package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a phase accumulator, COS lookup table, and 10-bit digital-to-analog converter on a single CMOS chip.
• Provides hardware capabilities for both phase modulation and frequency modulation via serial interface register loading.
• Includes a dedicated power-down option that significantly reduces power consumption when the device is inactive.

Applications

• Frequency stimulus and waveform generation
• Frequency and phase tuning and modulation systems
• Low power RF and communications equipment
• Liquid and gas flow measurement instrumentation
• Sensory applications including proximity, motion, and defect detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packaging formats. Confirm that the component meets all applicable environmental compliance standards relevant to the target deployment region before finalizing acquisition.

Selection Notes

Select this component for designs requiring high-frequency stability and precise phase control without external analog synthesis loops. Ensure the system architecture accommodates the 5 V power supply requirement and provides adequate decoupling for the analog and digital sections to maintain signal integrity.

Part Context

This part belongs to the AD9835 series of direct digital synthesizers. It serves as a complete solution for generating programmable waveforms by combining digital control logic with analog conversion. The series is designed to replace traditional complex frequency synthesizers in compact electronic systems.
