AD8554AR-REEL7

Overview

The AD8554AR-REEL7 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 maximum offset voltage of 10 μV across the extended temperature range and an input bias current of 1.5 nA at +125°C. The device offers a gain bandwidth product of 1 MHz at 2.7 V and 1.5 MHz at 5 V, with a typical slew rate of 0.4 V/μs. It provides high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) exceeding 130 dB.

Feature Summary

• Utilizes auto-zero stabilization architecture to achieve ultralow offset voltage and drift.
• Supports rail-to-rail input and output swings for maximum dynamic range.
• Operates reliably within the extended industrial temperature range of -40°C to +125°C.
• Requires no external capacitors for stability or operation.

Applications

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

Procurement Notes

Verify the specific ordering suffix AR-REEL7 against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required operating voltage range and load conditions. Cross-reference the datasheet revision F specifications for accurate performance parameters under your specific application constraints.

Selection Notes

Select this component when sub-microvolt offset and minimal drift are critical requirements. The quad configuration allows multiple channels in a single package, reducing board space. Verify that the 2.7 V to 5 V single-supply constraint fits the system design. Consider the 14-lead SOIC package dimensions for PCB layout planning.

Part Context

This part belongs to the AD8551/AD8552/AD8554 family of precision amplifiers. The AD8554 specifically contains four independent amplifiers, whereas the AD8551 is single-channel and the AD8552 is dual-channel. All share the same zero-drift technology and electrical characteristics, differing primarily in channel count and package options.

Replacement Considerations

Direct functional replacements within the same family include AD8551AR-REEL7 and AD8552AR-REEL7, provided pinout compatibility is verified for the specific package variant. Other zero-drift amplifiers may require circuit redesign due to differences in architecture or pin configurations.

FAQ

Does the AD8554 require external compensation capacitors?

No, the AD8554 does not require external capacitors for stability or operation.

What is the mechanism used to achieve low offset drift?

The device uses an auto-zero stabilization topology that continuously corrects offset voltage errors.
