AD8606AR-REEL

Overview

The AD8606AR-REEL is a dual-channel, precision, low-noise CMOS operational amplifier manufactured by Analog Devices. It features rail-to-rail input and output capabilities with a maximum offset voltage of 65 µV and an input bias current of 1 pA. The device operates on a single supply ranging from 2.7 V to 5.5 V and offers a unity-gain bandwidth of 10 MHz. Packaged in an 8-lead MSOP format, it is specified over the extended industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify the specific package suffix against the manufacturer's ordering guide to ensure compatibility with the required footprint. Confirm that the tape-and-reel packaging aligns with automated assembly requirements. Check for any recent revision updates in the datasheet that may affect performance specifications or pin configurations.

Selection Notes

Select this component when high DC accuracy and low noise are critical in portable applications. The low input bias current makes it suitable for high-impedance sensor interfaces. Ensure the design accounts for the extended industrial temperature range if operating in harsh environments.

Part Context

This part belongs to the AD860x family, which includes single (AD8605) and quad (AD8608) channel variants. All members share similar electrical characteristics, including low offset voltage and rail-to-rail I/O. The AD8606 specifically provides two channels in compact surface-mount packages.

Replacement Considerations

Consult the official Analog Devices replacement matrix for verified substitutes. Ensure any alternative maintains the same package type and thermal characteristics. Verify that the substitute meets the specific noise and offset voltage requirements of the original design.

FAQ

Does the AD8606 exhibit output phase reversal?

No, the AD8606 does not exhibit output phase reversal even for inputs exceeding the supply voltage by more than 2 V.

What is the maximum input voltage range?

The input voltage range extends from ground to the positive supply voltage (VS).
