AD8554ARZ-REEL

Overview

The AD8554ARZ-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 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. The device delivers high common-mode rejection and power supply rejection ratios 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.
• Provides full rail-to-rail input and output voltage swing capability for maximum dynamic range.
• Features extremely low input bias current and high open-loop gain without requiring external capacitors.

Applications

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

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging suitable for automated assembly. Confirm the RZ suffix corresponds to the 14-lead narrow SOIC package. Ensure the component meets RoHS compliance standards required for your manufacturing process. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity before procurement.

Selection Notes

Select this component when high DC precision and stability are required in single-supply applications. The quad configuration allows multiple channels in a compact footprint. Consider the 1.5 MHz bandwidth and 400 mV/μs slew rate for signal conditioning tasks. Verify that the 2.7 V minimum supply voltage aligns with your system power constraints.

Part Context

This part belongs to the AD855x family of zero-drift amplifiers, which includes single (AD8551), dual (AD8552), and quad (AD8554) variants. All members share the same core auto-zero topology and electrical characteristics, differing primarily in channel count and package options. The AD8554 specifically integrates four independent amplifiers into one integrated circuit.

Replacement Considerations

Direct functional substitutes within the same family include the AD8554ARUZ (TSSOP package) or AD8554ARZ (tube packaging). Other compatible parts may include the AD8629 series, though pinouts and specific parameters should be verified against the datasheet.
