AD8552ARZ-REEL

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, ensuring compatibility with single-supply systems operating between 2.7 V and 5.5 V. The device utilizes an auto-zero stabilization topology to achieve ultralow offset voltage of 1 μV and drift of 0.005 μV/°C. Key electrical parameters include a gain-bandwidth product of 1.5 MHz, supply current of 850 μA per amplifier at 5 V, and high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) exceeding 130 dB. It operates within an extended temperature range of −40°C to +125°C.

Feature Summary

• Zero-drift architecture utilizing auto-zero stabilization for minimal offset voltage and drift over temperature.
• Rail-to-rail input and output capability enabling full signal swing from ground to the positive supply rail.
• Ultralow input bias current and offset voltage suitable for high-impedance sensor interfaces.
• High open-loop gain and exceptional CMRR/PSRR performance without requiring external capacitors.

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's official documentation to confirm packaging type and quantity specifications. Ensure the component matches the exact part number AD8552ARZ-REEL7 to guarantee correct package dimensions and pinout configuration. Cross-reference the datasheet revision to validate all electrical characteristics and absolute maximum ratings prior to integration into the design.

Selection Notes

Select this component when application requirements demand sub-microvolt offset stability and low drift in single-supply environments. The rail-to-rail I/O feature makes it suitable for low-voltage signal conditioning where maximizing dynamic range is critical. Consider the 1.5 MHz bandwidth and 850 μA supply current per channel for applications balancing precision with moderate speed and power consumption constraints.

Part Context

This device 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 technology and electrical performance profile but differ in channel count and available package options such as MSOP, SOIC, and TSSOP. The AD8552 specifically provides two independent channels in an 8-lead narrow SOIC surface-mount package.

Replacement Considerations

Direct functional substitutes within the same family include the AD8551ARZ (single channel) and AD8554ARZ (quad channel). Verify that any alternative replacement maintains the required 2.7 V to 5.5 V single-supply operation and rail-to-rail input/output capabilities to ensure circuit compatibility.
