AD8552ARZ-REEL7

Overview

The AD8552ARZ-REEL7 is a dual-channel zero-drift operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output swings, operating on a single supply from 2.7 V to 5.5 V. The device provides an offset voltage of 1 μV with a drift of 0.005 μV/°C. It offers a gain bandwidth product of 1.5 MHz, a slew rate of 0.4 V/μs, and a supply current of 850 μA per amplifier at 5 V. Input bias current is typically 20 pA. The component operates within a temperature range of -40°C to +125°C and is housed in an 8-lead narrow SOIC package.

Feature Summary

• Zero-drift architecture utilizing auto-zero stabilization for ultralow offset voltage and drift
• Rail-to-rail input and output capability enabling full signal swing across the supply range
• High common-mode rejection ratio and power supply rejection ratio exceeding 130 dB
• Ultralow input bias current ensuring minimal loading effects on high-impedance sources

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the AD8552 series is available in multiple packages including narrow SOIC and TSSOP. Confirm that the REEL7 designation corresponds to the intended tape and reel quantity for manufacturing integration. Ensure compatibility with the target PCB footprint for the 8-lead narrow SOIC configuration before finalizing procurement orders.

Selection Notes

Select this component when application requirements demand sub-microvolt offset stability without external trimming capacitors. It is suitable for single-supply designs requiring rail-to-rail performance. Consider the 1.5 MHz bandwidth and 0.4 V/μs slew rate for moderate-speed precision applications. Evaluate the 850 μA per amplifier supply current against 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) configurations. All members share the same core auto-zero topology and electrical characteristics but differ in channel count and package options. The AD8552 specifically provides two independent amplifiers in a compact surface-mount package.

Replacement Considerations

Direct functional replacements within the same family include AD8551ARZ for single-channel applications and AD8554ARZ for four-channel requirements. Verify pinout compatibility if substituting with other dual-channel precision amplifiers, as package variations may exist.
