AD8602DR

Overview

The AD8602DR is a dual precision 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 750 µA per amplifier. The device offers a gain bandwidth product of 8.4 MHz and a slew rate of 6 V/µs at 5 V supplies. Input offset voltage for the D grade is specified up to 6 mV maximum, while input bias current is typically 200 fA. It functions within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output architecture enables full signal swing in single-supply systems.
• Patented DigiTrim technology ensures low offset voltage without laser trimming.
• CMOS input stage provides extremely low input bias currents suitable for high impedance sources.
• Unity-gain stable design eliminates phase reversal during overdrive conditions.

Applications

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

Procurement Notes

Verify the specific 'D' grade designation upon procurement, as it indicates lower DC precision compared to 'A' grades. Confirm the SOIC-8 package suffix matches the required footprint. Ensure the component meets RoHS standards if applicable to the target assembly process. Cross-reference the manufacturer's ordering guide for exact availability and lead times.

Selection Notes

Select this component when cost-sensitive applications require wideband performance and rail-to-rail operation. The D grade is appropriate where strict DC precision is not critical but low power consumption is necessary. Consider the 8-lead SOIC package for standard surface-mount assembly requirements. Evaluate the trade-off between the higher offset voltage of the D grade and its cost benefits.

Part Context

The AD8602DR belongs to the AD860x family of precision amplifiers manufactured by Analog Devices. This family includes single (AD8601), dual (AD8602), and quad (AD8604) variants sharing identical electrical characteristics and pinouts. The DR suffix specifically denotes the dual-channel version housed in an 8-lead narrow SOIC package.

Replacement Considerations

Direct replacements include other AD8602 variants such as AD8602ARZ or AD8602ARMZ. Verify that substitute parts match the required package type and temperature range. Check if the replacement offers the same D-grade specifications or superior A-grade performance.
