AD8602WARZ-RL

Overview

The AD8602WARZ-RL is a dual-channel precision CMOS operational amplifier from Analog Devices, 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 maximum rating of 6 V. The device offers a gain-bandwidth product of 8.4 MHz at 5 V and 8.2 MHz at 3 V, alongside a slew rate of 6 V/µs at 5 V. Key electrical characteristics include an input offset voltage of 80 µV (A Grade), input bias current of 0.2 pA, and supply current of 750 µA per amplifier. It is housed in an 8-lead SOIC package and qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Utilizes DigiTrim technology for post-package trimming to achieve low offset voltage without laser trimming.
• Features true rail-to-rail input and output architecture extending common-mode range to both supply rails.
• Designed for high source impedance applications due to extremely low input bias currents.
• Ensures system stability with no phase reversal during overdrive conditions.

Applications

• Current sensing circuits
• Barcode scanners
• Battery-powered instrumentation
• Multipole filters

Procurement Notes

Verify the specific grade (A or D) and packaging suffix against the official Analog Devices ordering guide, as performance parameters vary significantly between grades. Confirm that the WARZ suffix corresponds to the correct industrial temperature range and SOIC-8 package variant required for your design. Ensure compatibility with AEC-Q100 requirements if automotive qualification is necessary for the final assembly.

Selection Notes

Select this component when single-supply operation with wide bandwidth and precision DC accuracy is required. The dual-channel configuration allows for cost-effective implementation of differential amplifiers or dual-stage filtering. Consider the low input bias current for interfacing with high-impedance sensors. Verify that the 8-lead SOIC package fits the available PCB real estate compared to MSOP alternatives.

Part Context

This part belongs to the AD860x family of precision CMOS amplifiers, which includes single (AD8601), dual (AD8602), and quad (AD8604) variants. The family shares core technologies like DigiTrim and rail-to-rail I/O but differs in channel count and package options. The AD8602 specifically provides two independent amplifiers in an 8-lead footprint, balancing performance and space efficiency.

Replacement Considerations

Check for AD8602ARZ or AD8602ARMZ equivalents within the same series for different package styles. Verify if the D-grade version meets the offset voltage requirements if cost reduction is prioritized over precision. Cross-reference pinouts to ensure compatibility with existing layouts.
