AD8602DR-REEL7

Overview

The AD8602DR-REEL7 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. Input offset voltage for the D grade is specified up to 6 mV maximum, while input bias current is typically 200 fA. It is housed in an 8-lead SOIC package.

Feature Summary

• Rail-to-rail input and output architecture maximizes dynamic range in single-supply systems
• Patented DigiTrim technology ensures superior DC precision 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
• Audio applications

Procurement Notes

Verify that the specific ordering suffix corresponds to the reel packaging format required for automated assembly processes. Confirm the D grade specification aligns with the acceptable DC precision limits for the target application, as this variant offers lower DC accuracy compared to higher grades while maintaining wideband performance.

Selection Notes

Select this component when cost-sensitive designs require wide signal bandwidth and rail-to-rail swing but can tolerate higher offset voltages. Ensure the operating environment remains within the extended industrial temperature range. Verify that the 8-lead SOIC footprint matches the PCB layout constraints and thermal requirements of the system.

Part Context

This part belongs to the AD8601/AD8602/AD8604 family of precision amplifiers manufactured by Analog Devices. The AD8602 specifically denotes the dual-channel configuration within this series. These devices utilize proprietary trimming techniques to achieve performance characteristics typically found in more expensive laser-trimmed counterparts.

Replacement Considerations

Check datasheets for AD8602ARZ or AD8602WARZ if stricter offset voltage specifications are required. Verify pin compatibility and electrical parameters against AD8602DRZ variants before substitution.
