AD8616ARMZ

Overview

The AD8616ARMZ is a dual precision operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities within a single-supply architecture. It operates on voltages ranging from 2.7 V to 5.0 V. The device utilizes CMOS technology to achieve a gain bandwidth product exceeding 20 MHz and a slew rate of 12 V/μs. Key electrical characteristics include a maximum offset voltage of 65 μV, low noise density of 8 nV/√Hz, and minimal input bias current of 1 pA. It is housed in an 8-lead MSOP package and supports operation across the extended industrial temperature range.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required supply voltage range and thermal management requirements for the target application environment.

Selection Notes

Select this component for designs requiring high precision and wide bandwidth in single-supply systems. The rail-to-rail I/O allows full utilization of the supply voltage range. Consider the low input bias current for high-impedance sensor interfaces and the high output current for driving low-impedance loads directly.

Part Context

This part belongs to the AD8615/AD8616/AD8618 family of precision, low-noise, CMOS, rail-to-rail input/output operational amplifiers. The AD8616 specifically denotes the dual-channel configuration within this series, sharing core performance metrics with the single (AD8615) and quad (AD8618) variants while differing in channel count and package options.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the same family or equivalent specifications. Verify pinout compatibility and thermal resistance values when replacing components in existing designs.

FAQ

Does the AD8616 exhibit output phase reversal?

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