AD8542ARMZ-REEL

Overview

The AD8542ARMZ-REEL is a dual-channel CMOS 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 with a typical supply current of 45 µA per amplifier. The device provides a gain-bandwidth product of approximately 1 MHz and maintains unity-gain stability without phase reversal. Input bias current is typically 4 pA, supporting high source impedance applications.

Feature Summary

• Rail-to-rail input and output voltage swing capability
• Low power consumption suitable for battery operation
• High input impedance with ultra-low bias current
• Unity-gain stable with no phase reversal

Applications

• ASIC input or output buffering
• Piezoelectric transducer amplifiers
• Photodiode amplifiers
• Active filters and gain stages
• Portable systems and medical instrumentation

Procurement Notes

Verify the specific package marking code RM-8 and suffix -REEL to confirm reel packaging configuration. Ensure the RoHS compliant designation (Z) matches environmental requirements. Cross-reference the ordering guide to validate the exact packing quantity associated with the reel variant before procurement.

Selection Notes

Select this component when low quiescent current and rail-to-rail performance are required in a dual-channel configuration. It is optimized for lower supply voltages while maintaining high gain. Consider the MSOP-8 package dimensions for board space constraints. Verify that the extended industrial temperature range meets system thermal specifications.

Part Context

This part belongs to the AD854x family of general-purpose CMOS amplifiers, which includes single (AD8541), dual (AD8542), and quad (AD8544) variants. The series is designed to replace older generation parts by offering similar bandwidth at significantly reduced power consumption. The AD8542 specifically provides two channels in an 8-lead surface-mount package.

Replacement Considerations

Direct functional replacements within the same family include AD8541ARUZ and AD8544ARUZ. Automotive qualified versions such as AD8544WARZ may be considered if automotive reliability standards are required, though specifications may differ.
