AD7766BRUZ-2-RL7

Overview

The AD7766BRUZ-2-RL7 is a high-performance, single-channel, 24-bit oversampled successive approximation (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates at an output data rate of 32 kSPS with a dynamic range of 115.5 dB and a signal-to-noise ratio of 113.5 dB. The device consumes 8.5 mW of power while operating from a 2.5 V supply. It features a differential input structure, an on-chip low-pass FIR filter with linear phase response, and a serial interface compatible with 1.8 V to 3.6 V logic levels. The component is housed in a 16-lead TSSOP package and supports daisy-chaining capabilities.

Feature Summary

• Oversampled SAR architecture providing high AC and DC accuracy with exceptionally low power consumption.
• Integrated digital FIR filter that eliminates out-of-band noise and reduces front-end antialiasing requirements.
• Flexible interfacing options including synchronization pins and daisy-chain capability for multi-device systems.

Applications

• Low power PCI/USB data acquisition systems
• Vibration analysis instrumentation
• High precision medical acquisition

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the AD7766BRUZ-2 variant matches the necessary 32 kSPS decimation rate for your system timing constraints. Ensure the external reference voltage meets the specified 5 V requirement for optimal performance.

Selection Notes

Select this model when the application requires the highest dynamic range and lowest power consumption among the AD7766 family. The AD7766-2 variant provides a 32 kSPS output rate, which is suitable for applications where bandwidth is less critical than ultra-low power operation and maximum resolution. Compare against AD7766-1 or standard AD7766 if higher throughput is needed.

Part Context

This component belongs to the AD7766 series of 24-bit ADCs, which includes variants optimized for different speed-power trade-offs. The AD7766-2 specifically targets the lowest power segment of the family. Related devices in the broader portfolio include the AD7760 and AD7762, which offer higher speeds but typically require more complex external circuitry or consume more power.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify compatibility with existing board layouts and software drivers if considering alternative ADCs from other manufacturers.
