AD8602DR-REEL

Overview

The AD8602DR-REEL 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, a slew rate of 6 V/µs, and an input offset voltage maximum of 6000 µV for the D grade. It utilizes patented DigiTrim technology for post-package trimming without laser adjustment.

Feature Summary

• Patented DigiTrim technology achieves superior performance without laser trimming
• True rail-to-rail input and output architecture maximizes usable voltage range
• Very low input bias currents suitable for high source impedance applications
• No phase reversal ensures stable operation during overload conditions

Applications

• Current sensing
• Barcode scanners
• Battery-powered instrumentation
• Multipole filters
• ASIC input or output amplifiers

Procurement Notes

Verify that the specific part number matches the required package type and reel configuration. Confirm the D grade specifications align with design requirements regarding offset voltage limits. Ensure compatibility with the intended operating temperature range and supply voltage constraints before finalizing procurement decisions.

Selection Notes

Select this component when single-supply operation and wide bandwidth are required alongside low power consumption. The D grade provides cost-effective performance for applications where extreme DC precision is not critical. Consider the SOIC-8 package dimensions for PCB layout planning and verify thermal resistance characteristics for the specific mounting environment.

Part Context

This dual-channel amplifier belongs to the AD8601/AD8602/AD8604 family of precision CMOS devices. The family shares common electrical characteristics including rail-to-rail I/O and low noise profiles. The AD8602 specifically integrates two independent amplifiers in a compact surface-mount package, offering a solution for space-constrained designs requiring multiple signal conditioning stages.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar gain-bandwidth products and supply voltage ranges. Verify that any substitute maintains the rail-to-rail input/output capability and meets the specific offset voltage and bias current requirements of the original design.
