AD9835BRUZ

Overview

The AD9835BRUZ is a Direct Digital Synthesizer (DDS) waveform generator manufactured by Analog Devices Inc. It integrates a phase accumulator, COS lookup table, and a 10-bit digital-to-analog converter on a single CMOS chip. The device supports clock rates up to 50 MHz with a resolution of 10 bits and operates within a supply voltage range of 4.75 V to 5.25 V. It features serial loading capabilities for modulation control and includes a power-down option that reduces consumption to 1.75 mW. The component is housed in a 16-lead TSSOP package and functions across an industrial temperature range from −40°C to +85°C.

Feature Summary

• Integrates a numerically controlled oscillator with a 32-bit phase accumulator and a cosine lookup table for precise frequency synthesis.
• Includes a high-impedance current source 10-bit DAC capable of generating analog waveforms directly from digital inputs.
• Supports both phase modulation and frequency modulation through dedicated registers and serial interface commands.
• Features a low-power sleep mode accessible via a specific bit command to minimize energy usage during idle periods.

Applications

• Frequency stimulus and waveform generation systems
• Low power RF and communications equipment
• Liquid and gas flow measurement instrumentation
• Sensory applications including proximity, motion, and defect detection
• Test and medical equipment requiring precise signal sources

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status as indicated in the latest datasheet revision. Check for any end-of-life notices or obsolescence warnings prior to finalizing procurement plans. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Selection Notes

Select this component when a fully integrated DDS solution with serial interface control is required. Ensure the system design accommodates the 5 V power supply requirement and the 16-lead TSSOP footprint. Verify that the external load resistor and reference capacitor values align with the specified full-scale current and internal reference characteristics for optimal linearity.

Part Context

This part belongs to the AD9835 series of direct digital synthesizers produced by Analog Devices. It serves as a compact alternative to traditional frequency synthesizers by combining NCO, LUT, and DAC functions. The BRUZ suffix indicates the commercial/industrial temperature grade variant packaged in a TSSOP housing, distinct from other package options available in the broader product family.

Replacement Considerations
