AD8616AR

Overview

The AD8616AR is a dual-channel precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, making it suitable for single-supply systems operating between 2.7 V and 5.0 V. The device utilizes CMOS technology to achieve a gain bandwidth product of 24 MHz and a slew rate of 12 V/μs. Key electrical characteristics include a maximum offset voltage of 65 μV, low input bias current of 1 pA, and high output drive capability of 150 mA. It operates within an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output operation enables full signal swing in single-supply applications.
• Patented DigiTrim trimming technique ensures superior precision without laser trimming.
• Immune to output phase reversal when input common-mode voltage exceeds the supply rails.
• High output drive capability supports low impedance loads and audio line driving.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required thermal management and PCB layout guidelines for surface-mount installation.

Selection Notes

Select this component for designs requiring high DC accuracy combined with wide AC bandwidth. The low offset voltage and drift make it ideal for precision sensor interfaces, while the rail-to-rail performance optimizes dynamic range in low-voltage battery-operated systems.

Part Context

This part belongs to the AD8615/AD8616/AD8618 family of precision, 20 MHz, CMOS, rail-to-rail input/output operational amplifiers. The AD8616 specifically denotes the dual-channel configuration within this series, sharing core performance metrics with its single (AD8615) and quad (AD8618) counterparts.

Replacement Considerations

Consult the official Analog Devices ordering guide for confirmed substitute part numbers. Verify that any alternative maintains the same channel count, package dimensions, and electrical specifications such as offset voltage and bandwidth.

FAQ

Does the AD8616 exhibit output phase reversal?

No, the AD8616 is immune to phase inversion, even when the input common-mode voltage exceeds the supply rails.

What is the maximum power dissipation limit?

The absolute maximum junction temperature is 150°C. Power dissipation must be calculated based on load current, supply voltage, and output voltage to ensure this limit is not exceeded.
