AD8602AR

Overview

The AD8602AR is a dual-channel, 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 an 8.4 MHz gain-bandwidth product and a slew rate of 6 V/µs at 5 V. Key electrical specifications include a maximum offset voltage of 500 µV (A Grade) or 1300 µV (D Grade), input bias current of 60 pA, and common-mode rejection ratio of 89 dB.

Feature Summary

• Utilizes DigiTrim technology for post-assembly offset voltage trimming without laser adjustment.
• Features true rail-to-rail input and output architecture extending 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 in power management circuits
• Barcode scanners and portable instrumentation
• Battery-powered measurement devices
• Multipole filters and sensor signal conditioning

Procurement Notes

Verify the specific grade suffix (A or D) required for your application's precision needs before ordering. Confirm that the SOIC-8 package variant matches your PCB footprint requirements. Ensure the operating temperature range aligns with your environmental constraints, as the device supports extended industrial temperatures.

Selection Notes

Select the A Grade for applications requiring lower maximum offset voltage and higher CMRR. Choose the D Grade for cost-sensitive designs where slightly higher DC errors are acceptable. Consider the AD8601 if only a single channel is needed, or the AD8604 for quad-channel integration within the same family specifications.

Part Context

This component belongs to the AD860x family of precision amplifiers manufactured by Analog Devices. The family includes single (AD8601), dual (AD8602), and quad (AD8604) variants sharing identical core performance characteristics. The AD8602 specifically provides two independent channels in an 8-lead surface-mount package suitable for space-constrained designs.

Replacement Considerations

Direct functional substitutes within the same family include the AD8601 (single channel) and AD8604 (quad channel). Automotive qualified versions such as the AD8602WARZ may be considered if automotive reliability standards are required, though pinouts and basic specs remain consistent across the series.
