Overview
The AD8572ARUZ-REEL is a dual-channel, zero-drift operational amplifier from Analog Devices, housed in an 8-lead TSSOP package. It operates on a single supply voltage ranging from 2.7 V to 5 V. Key electrical characteristics include a typical input offset voltage of 1 μV and an input bias current of 10 pA. The device features rail-to-rail input and output capabilities, a gain bandwidth product of 1.5 MHz, and a typical open-loop gain of 145 dB. It maintains performance across an extended industrial temperature range of -40°C to +125°C.
Feature Summary
- Utilizes spread-spectrum auto-zero technology to eliminate intermodulation distortion without requiring external capacitors.
- Provides rail-to-rail input and output swing capability for maximum dynamic range within the supply voltage limits.
- Features ultralow offset voltage and drift specifications to ensure high DC precision over wide temperature variations.
Applications
- Temperature sensors
- Pressure sensors
- Precision current sensing
- Strain gage amplifiers
- Medical instrumentation
Procurement Notes
Verify the specific suffix RUZ against the manufacturer's ordering guide to confirm the 8-lead TSSOP package and reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the operating voltage range aligns with your system's power supply constraints before integration.
Selection Notes
Select this component when high DC accuracy and low drift are critical, particularly in single-supply environments. The rail-to-rail I/O makes it suitable for low-voltage signal conditioning where maximizing dynamic range is necessary. Consider the thermal resistance characteristics if operating at the upper limits of the specified temperature range.
Part Context
This part belongs to the AD857x family of zero-drift amplifiers, which includes single (AD8571), dual (AD8572), and quad (AD8574) configurations. The family shares identical core architecture and electrical performance metrics, differing primarily in channel count and physical package options such as MSOP, SOIC, and TSSOP.
Replacement Considerations
Direct pin-compatible substitutes within the same family include the AD8571ARUZ for single-channel applications and the AD8574ARUZ for quad-channel requirements. Verify that any alternative component matches the 8-lead TSSOP footprint and the 2.7 V to 5 V single-supply operation constraint.
