AD8554AR-REEL

Overview

The AD8554AR-REEL is a quad zero-drift operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It operates on a single supply ranging from 2.7 V to 5 V. Key electrical specifications include an offset voltage of 1 μV with a drift of 0.005 μV/°C, an input bias current of 20 pA, and a gain bandwidth product of 1.5 MHz. The device provides high common-mode rejection and power supply rejection ratios of 130 dB, along with an overload recovery time of 50 μs.

Feature Summary

• Zero-drift architecture utilizing auto-zero stabilization for submicrovolt offset voltages and minimal temperature drift.
• Rail-to-rail input and output stages enabling full signal swing across the entire supply voltage range.
• High precision performance characterized by 130 dB common-mode and power supply rejection ratios.
• Ultralow input bias current of 20 pA combined with low supply current consumption per amplifier.

Applications

• Temperature sensors
• Pressure sensors
• Precision current sensing
• Strain gage amplifiers
• Medical instrumentation

Procurement Notes

Verify the specific ordering suffix AR-REEL against official documentation to confirm package type and reel packaging configuration. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Confirm that the quad channel configuration meets system requirements. Cross-reference datasheet revisions to validate updated electrical characteristics before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high DC accuracy without external trimming capacitors. The zero-drift technology eliminates the need for additional filtering components typically required with chopper amplifiers. Consider the rail-to-rail capability when designing for low-voltage single-supply systems. Evaluate the 1.5 MHz bandwidth against signal frequency requirements to ensure adequate dynamic performance.

Part Context

The AD8554 is part of the AD8551/AD8552/AD8554 family of precision amplifiers designed for single-supply operation. This series combines the benefits of expensive auto-zeroing or chopper-stabilized topologies with lower cost and simplified design. The quad configuration allows multiple channels to be integrated into compact designs suitable for space-constrained industrial and automotive environments.
