AD8539ARZ-REEL7

Overview

The AD8539ARZ-REEL7 is a dual-channel, low-power, precision auto-zero operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V or dual supplies of ±1.35 V to ±2.5 V. The device features an extremely low input offset voltage with a maximum of 16 µV and minimal drift of 0.03 µV/°C across the extended industrial temperature range of −40°C to +125°C. Key electrical parameters include a gain-bandwidth product of 430 kHz, a slew rate of 0.4 V/µs, and a supply current of approximately 210 µA per amplifier at 5 V. It utilizes an 8-lead narrow body SOIC package.

Feature Summary

Auto-zero architecture ensures ultra-low offset voltage and negligible drift over temperature variations.
Low power consumption design suitable for battery-operated and portable instrumentation applications.
High common-mode rejection ratio and power supply rejection ratio for precise signal conditioning.

Applications

Mobile communications
Portable instrumentation
Battery-powered devices
Sensor interfaces
Temperature measurement

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to tape-and-reel packaging when sourcing components. Confirm that the automotive qualification status applies only to models designated with the W suffix, as standard commercial parts may not meet automotive reliability standards. Ensure the RoHS compliance designation matches current environmental regulations for your region before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high DC accuracy without external trimming due to its auto-zero technology. Consider the 8-lead SOIC package constraints regarding board space compared to MSOP options. Evaluate the 430 kHz bandwidth against signal frequency requirements to ensure adequate phase margin and stability under expected capacitive loading conditions.

Part Context

This part belongs to the AD8538/AD8539 family of precision amplifiers. The AD8539 specifically denotes the dual-channel version, whereas the AD8538 is the single-channel counterpart. Both share identical core specifications but differ in channel count and pin configurations within their respective packages.

Replacement Considerations

The AD8539ARMZ serves as a direct functional replacement offering the same electrical characteristics in an 8-lead MSOP package instead of the SOIC format.
