AD8554ARZ-REEL7

Overview

The AD8554ARZ-REEL7 is a quad precision operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It operates on a single supply voltage 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 delivers high common-mode rejection and power supply rejection ratios exceeding 130 dB, with a supply current of approximately 700 μA per amplifier.

Feature Summary

• Zero-drift architecture utilizing auto-zero stabilization for ultralow offset voltage and drift across the operating temperature range.
• Rail-to-rail input and output swing capability enabling full dynamic range operation on single-supply systems.
• High open-loop gain and exceptional common-mode and power supply rejection ratios exceeding 130 dB.
• Ultralow input bias current and low supply current consumption without requiring external capacitors.

Applications

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

Procurement Notes

Verify the specific REEL7 suffix against the manufacturer's ordering guide to confirm tape-and-reel packaging and quantity specifications. Ensure the component matches the exact AD8554 family designation for quad channel configurations. Cross-reference datasheet revision F for updated electrical characteristics and absolute maximum ratings prior to integration.

Selection Notes

Select this component for applications requiring high precision in harsh environments due to its extended industrial temperature range of −40°C to +125°C. The zero-drift technology eliminates the need for external trimming or capacitors, simplifying circuit design. Consider the rail-to-rail performance for maximizing signal integrity in low-voltage single-supply systems.

Part Context

This part belongs to the AD8551/AD8552/AD8554 series of zero-drift, single-supply, rail-to-rail input/output operational amplifiers. The AD8554 specifically provides four independent amplifiers within a single package. The series combines the accuracy of expensive auto-zeroing topologies with cost-effective CMOS manufacturing processes.

Replacement Considerations

Consult the official Analog Devices ordering guide for verified substitute part numbers within the AD855x family or equivalent zero-drift amplifier series. Verify pin compatibility and electrical specifications before substituting.
