AD9832BRU-REEL7

Overview

The AD9832BRU-REEL7 is a direct digital synthesizer featuring a 10-bit DAC and on-chip sine lookup table. It supports clock rates up to 25 MHz with frequency accuracy of one part in 4 billion. The device operates on a single 3 V to 5.5 V supply, consuming 200 mW typically. It includes two 32-bit frequency registers and four 12-bit phase registers for modulation. Power consumption reduces to 5 mW at 5 V or 3 mW at 3 V in power-down mode. The component is housed in a 16-lead TSSOP package and functions within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrated numerically controlled oscillator with phase accumulator and sine look-up table
• Built-in 10-bit digital-to-analog converter with adjustable full-scale current
• Supports serial interface for loading frequency and phase data
• Configurable power-down option for reduced energy consumption

Applications

• Frequency stimulus and waveform generation
• Frequency phase tuning and modulation in communications systems
• Liquid and gas flow measurement instrumentation
• Sensory applications including proximity and motion detection
• Test and medical equipment signal sources

Procurement Notes

Verify the specific ordering suffix RU-REEL7 confirms tape and reel packaging when sourcing. Confirm the B version designation matches the required industrial temperature range specifications. Ensure the supplier provides documentation consistent with Analog Devices Rev E datasheet standards for this component.

Selection Notes

Select this component for designs requiring integrated DDS functionality without external ROM or complex DAC interfaces. Consider the 10-bit resolution limits for high-linearity requirements. Evaluate the 25 MHz maximum clock speed against desired output frequencies. Verify power supply constraints align with the 3 V to 5.5 V operating range.

Part Context

This model belongs to the AD9832 family of direct digital synthesizers from Analog Devices. It shares core architecture with similar DDS products but differs in package type and specific ordering suffixes. The BRU variant indicates the specific lead-free TSSOP packaging configuration available for surface mount assembly processes.

Replacement Considerations

Direct substitutes include other AD9832 variants with different packages or suffixes. Cross-reference pin compatibility and electrical specifications before substitution. Verify that alternative components support the same 25 MHz clock rate and 10-bit DAC resolution.
