AD7766BRUZ-1-RL7

Overview

The AD7766BRUZ-1-RL7 is a high-performance, single-channel, 24-bit analog-to-digital converter (ADC) utilizing an oversampled successive approximation register (SAR) architecture. It operates at a fixed output data rate of 64 kSPS with a decimation factor of 16. The device delivers a dynamic range of 112.5 dB and a signal-to-noise ratio (SNR) of 111.5 dB at full-scale input. Power consumption is rated at 10.5 mW under standard operating conditions. It features a differential analog input structure, an on-chip low-pass FIR filter with linear phase response, and supports serial interfacing with daisy-chain capability.

Feature Summary

• Oversampled SAR architecture providing high AC and DC accuracy with exceptionally low power consumption.
• Integrated digital FIR filter offering linear phase response to eliminate out-of-band noise and reduce antialiasing requirements.
• Flexible digital interface supporting synchronization of multiple devices and daisy-chain configuration via SDI pin.

Applications

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

Procurement Notes

Verify the specific suffix -1 indicates the 64 kSPS variant when sourcing. Confirm package type is TSSOP-16. Check RoHS compliance status for the reel packaging. Ensure logic voltage levels match system requirements.

Selection Notes

Select this model over the standard AD7766 if a lower data rate of 64 kSPS is required to optimize power consumption while maintaining high resolution. Choose the AD7766-2 variant if further power reduction to 32 kSPS is acceptable. Ensure the external reference voltage supports the 5 V requirement for optimal performance.

Part Context

This component belongs to the AD7766 family of 24-bit ADCs from Analog Devices. The family includes variants with different decimation rates: AD7766 (128 kSPS), AD7766-1 (64 kSPS), and AD7766-2 (32 kSPS). All share the same core architecture and pinout but differ in filtering depth and power efficiency.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The AD7767 series offers similar specifications but differs in INL performance and power profiles.
