AD8554ARUZ-REEL

Overview

The AD8554ARUZ-REEL is a quad zero-drift operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply ranging from 2.7 V to 5.5 V with a typical supply current of 700 μA per amplifier. Key electrical specifications include an offset voltage of 1 μV, an input offset drift of 0.005 μV/°C, and an ultralow input bias current of 20 pA. The device provides high gain, CMRR, and PSRR of 130 dB, along with a gain bandwidth product of 1 MHz and an overload recovery time of 50 μs.

Feature Summary

• Zero-drift architecture utilizing auto-zero stabilization for submicrovolt offset voltage and minimal temperature drift.
• Rail-to-rail input and output swing capability enabling full signal utilization within the supply voltage range.
• Ultralow input bias current and offset voltage ensuring high precision in sensitive measurement applications.

Applications

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

Procurement Notes

Verify the specific package suffix RU corresponds to the 14-lead TSSOP configuration required for your design. Confirm that the REEL designation matches your automated assembly equipment specifications. Ensure the component meets the extended industrial temperature range requirements of -40°C to +125°C for your intended operating environment.

Selection Notes

Select this component when ultra-low offset voltage and drift are critical, such as in thermocouple or strain gauge interfaces. The rail-to-rail I/O makes it suitable for low-voltage single-supply systems where maximizing dynamic range is necessary. Consider the 1 MHz bandwidth and slew rate limitations if higher speed signal processing is required.

Part Context

This part belongs to the AD8551/AD8552/AD8554 family of zero-drift, single-supply, rail-to-rail input/output operational amplifiers. The AD8554 variant specifically integrates four independent amplifiers within a single package, offering a compact solution for multi-channel precision signal conditioning tasks.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the AD8551 (single) and AD8552 (dual). Verify that any alternative zero-drift amplifier maintains comparable input bias current and offset drift specifications to ensure circuit accuracy is preserved.

FAQ

Does the AD8554 require external capacitors for stability?

No external capacitors are required for basic operation, as the internal auto-zero architecture handles offset correction without additional compensation components.

What is the maximum supply voltage for the AD8554?

The absolute maximum supply voltage rating is 6 V, though the recommended operating range is specified from 2.7 V to 5.5 V.
