AD45266-RL

Overview

The AD45266-RL is a high-performance, low-noise, precision operational amplifier manufactured by Analog Devices Inc. It belongs to the ADA4522 series and features a single-channel architecture housed in an SOIC-8 surface-mount package. Key electrical specifications include a gain-bandwidth product of 2.7 MHz and a slew rate of 1.7 V/us. The device exhibits ultra-low input offset voltage of 1.5 uV and input bias current of 50 pA. It operates on a supply voltage range from 4.5 V to 55 V with a quiescent current of 840 uA per channel. The component supports a shutdown function and functions within a temperature range of -40 C to +125 C.

Feature Summary

• Zero drift architecture ensures minimal offset voltage drift over time and temperature variations.
• Ultra-low noise performance suitable for sensitive signal conditioning applications.
• Integrated shutdown capability allows for power management and extended battery life.
• High common-mode rejection ratio maintains accuracy in noisy environments.

Applications

• Precision sensor signal conditioning
• Medical instrumentation front-ends
• Industrial process control systems
• Data acquisition systems

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm packaging type and reel quantity. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm availability status as distribution channels may report limited stock or restricted supply conditions. Validate RoHS compliance and lead times directly with authorized distributors prior to finalizing procurement plans.

Selection Notes

Select this component when zero-drift stability and low noise are critical requirements. Compare the 2.7 MHz bandwidth against application speed needs. Evaluate the 55 V maximum supply voltage against system rail constraints. Consider the SOIC-8 package size for space-constrained designs. Verify that the 840 uA quiescent current aligns with power budget limitations.

Part Context

This part is part of the ADA4522 family of precision amplifiers designed for high-accuracy applications. The series is characterized by its chopper-stabilized technology which eliminates drift. The AD45266-RL specifically denotes the reel-packaged version of the ADA4522-1ARZ device, intended for automated surface-mount assembly processes in manufacturing environments.

Replacement Considerations

Direct substitutes within the same family include ADA4522-1ARZ and ADA4522-1ARZ-R7. Verify pinout compatibility and electrical parameter equivalence before substitution. Multi-channel variants like ADA4522-4ARZ offer similar performance but require different footprint considerations.
