AD8554ARU-REEL

Overview

The AD8554ARU-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 a typical 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 at 5 V. The device provides high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of 130 dB, with a supply current of approximately 700 μA per amplifier.

Feature Summary

• Utilizes auto-zero stabilization architecture to achieve ultralow offset voltage and drift over the operating temperature range.
• Features rail-to-rail input and output swings compatible with single-supply operation.
• Provides high open-loop gain and exceptional common-mode and power supply rejection ratios.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel configuration. Ensure the component matches the required channel count and performance specifications for the target application. Cross-reference the datasheet revision to validate all electrical parameters before integration into the design.

Selection Notes

Select this component for applications requiring high DC precision without external trimming. The zero-drift technology eliminates the need for additional capacitors typically required in chopper-stabilized designs. Consider the extended industrial temperature range and low supply current when designing battery-powered or thermally constrained systems.

Part Context

This part belongs to the AD8551/AD8552/AD8554 family of single-supply, rail-to-rail operational amplifiers. The AD8554 variant specifically contains four independent amplifiers within a single package. The series is designed to provide the accuracy of expensive auto-zeroing amplifiers at a lower cost point.

Replacement Considerations

Official substitutes within the same family include the AD8551 (single channel) and AD8552 (dual channel). Verify pin compatibility and electrical characteristics if substituting with other quad precision amplifiers from different manufacturers.

FAQ

Does the AD8554 require external capacitors for stability?

No, the AD8554 does not require external capacitors for its auto-zero operation.

What is the maximum supply voltage for the AD8554?

The absolute maximum supply voltage rating is 6 V, though it is guaranteed to operate between 2.7 V and 5 V.
