AD8552AR-REEL

Overview

The AD8552AR-REEL7 is a dual-channel, zero-drift operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical specifications include a typical offset voltage of 1 μV, an input bias current of 300 pA at +85°C, and a gain-bandwidth product of 1.5 MHz. The device provides a slew rate of 400 mV/μs and maintains high common-mode rejection and power supply rejection ratios exceeding 115 dB across the industrial temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift architecture utilizing auto-zero stabilization to maintain ultralow offset voltage and drift over temperature.
• Rail-to-rail input and output swing capability enabling full signal utilization within the supply voltage range.
• High open-loop gain and exceptional common-mode and power supply rejection ratios for precision applications.
• Ultralow input bias current characteristics suitable for high-impedance sensor interfaces.

Applications

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

Procurement Notes

Verify the specific suffix 'R' indicates the SOIC-8 package variant when sourcing this component. Confirm that the REEL7 designation corresponds to the required tape-and-reel packaging format for automated assembly processes. Ensure compatibility with the intended operating voltage range of 2.7 V to 5.5 V.

Selection Notes

Select this component for applications requiring sub-microvolt offset stability without external trimming capacitors. It is suitable for single-supply systems where rail-to-rail performance is critical. Consider the extended temperature rating for automotive or harsh industrial environments. Evaluate the 1.5 MHz bandwidth against signal frequency requirements.

Part Context

This part belongs to the AD855x family of zero-drift amplifiers, which includes single (AD8551) and quad (AD8554) variants. The series combines low cost with high accuracy typically found in expensive chopper-stabilized amplifiers. The AD8552 specifically provides two independent channels in a compact surface-mount package.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the AD8551ARZ (single channel) and AD8554ARZ (quad channel). Verify package integrity and electrical parameter alignment before substituting with other zero-drift op-amps.
