AD9832BRUZ-REEL7

Overview

The AD9832BRUZ-REEL7 is a direct digital synthesizer (DDS) waveform generator manufactured by Analog Devices Inc. It integrates a numerically controlled oscillator, a sine look-up table, and a 10-bit digital-to-analog converter on a single CMOS chip. The device supports clock rates up to 25 MHz and provides frequency accuracy of one part in 4 billion. It operates within a supply voltage range of 2.97 V to 5.5 V for both analog and digital sections. The component features a serial interface for loading data registers and includes power-down options reducing consumption to 3 mW at 3 V. It is housed in a 16-lead TSSOP package and functions across an industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrates a 32-bit phase accumulator, sine look-up table, and 10-bit DAC for complete waveform generation.
• Supports frequency modulation and phase modulation via serial register loading.
• Includes a low-power sleep mode with programmable wake-up capabilities.
• Features dual frequency registers and four selectable phase offset registers.

Applications

• Frequency stimulus and waveform generation
• Frequency 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 REEL7 confirms tape and reel packaging upon purchase. Confirm the B version designation matches the required industrial temperature range specifications. Ensure the source documentation explicitly lists the AD9832BRUZ-REEL7 as the active part number to avoid confusion with tube-packaged variants or older revisions.

Selection Notes

Select this component when a fully integrated DDS solution with 10-bit resolution is required. Verify that the maximum clock frequency of 25 MHz meets the system's Nyquist requirements. Check if the serial interface timing characteristics align with the host microprocessor capabilities. Consider the power consumption profiles during active and sleep modes for battery-operated designs.

Part Context

This part belongs to the AD9832 series of direct digital synthesizers from Analog Devices. It serves as a compact alternative to discrete signal generation circuits. The BRUZ variant specifically denotes the surface-mount TSSOP package configuration suitable for automated assembly processes in modern electronic manufacturing.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Analog Devices resources for cross-reference information regarding newer DDS generations or pin-compatible alternatives.
