AD8616ARZ

Overview

The AD8616ARZ is a dual precision CMOS operational amplifier from Analog Devices, housed in an 8-lead SOIC package. It operates on single supplies ranging from 2.7 V to 5.0 V with a typical supply current of 1.7 mA per amplifier. Key electrical specifications include a maximum offset voltage of 65 µV, a gain bandwidth product of 24 MHz, and a slew rate of 12 V/µs. The device features rail-to-rail input and output capabilities, low noise density of 10 nV/√Hz, and high output drive current up to 150 mA.

Feature Summary

• Patented DigiTrim trimming technique achieves superior precision without laser trimming
• Immune to output phase reversal when input common-mode voltage exceeds rails
• Rail-to-rail input and output operation enables full signal swing in single-supply systems

Applications

• Buffering CMOS ADCs and DACs in data acquisition systems
• High-speed photodiode preamplifiers utilizing I-to-V conversion
• Precision multipole filter design for signal conditioning
• Audio amplification for portable devices and line drivers
• Battery-powered instrumentation requiring low power consumption

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and temperature grade. Confirm that the component matches the required industrial operating range and pin configuration before integration into the final design.

Selection Notes

Select this component for applications demanding high DC accuracy combined with wide AC bandwidth. The low input bias current and low noise make it suitable for high-impedance sensor interfaces. Ensure the load capacitance is managed to maintain stability, as heavy capacitive loads may require external compensation networks.

Part Context

This part belongs to the AD8615/AD8616/AD8618 family of precision, rail-to-rail operational amplifiers. While sharing core performance characteristics such as bandwidth and noise, the family differentiates by channel count, with the AD8616 specifically providing two independent amplifiers in a compact surface-mount package.

Replacement Considerations

Official substitutes within the same family include the AD8615 for single-channel requirements and the AD8618 for quad-channel configurations. These parts share identical electrical specifications but differ in package pin counts and internal topology.

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 output short-circuit duration?

The device supports indefinite output short-circuit duration to ground without damage.
