AD8606ARZ-REEL7

Overview

The AD8606ARZ-REEL7 is a dual-channel, precision, low-noise CMOS operational amplifier manufactured by Analog Devices. It features rail-to-rail input and output capabilities, operating on a single supply voltage ranging from 2.7 V to 5.5 V. The device utilizes DigiTrim® technology for superior precision without laser trimming. Key electrical specifications include a maximum offset voltage of 65 μV, maximum input bias current of 1 pA, and a voltage noise density of 8 nV/√Hz at 1 kHz. It offers a unity-gain bandwidth of 10 MHz and a slew rate of 5 V/μs. The component is housed in an 8-lead narrow SOIC surface-mounted package and is specified over the extended industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and pinout compatibility. Confirm that the selected variant meets all environmental and electrical requirements for the intended application before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring high DC accuracy and low noise in single-supply environments. The rail-to-rail I/O capability maximizes dynamic range in low-voltage systems. Ensure adequate power supply decoupling is implemented near the device pins to maintain stability and minimize noise coupling.

Part Context

The AD8606ARZ-REEL7 belongs to the AD8605/AD8606/AD8608 family of precision, low-noise, CMOS, rail-to-rail input/output operational amplifiers. This series is designed for applications demanding high precision and speed. The AD8606 specifically provides two independent channels within a compact footprint, making it suitable for space-constrained multi-channel signal processing tasks.

Replacement Considerations

Consult the official Analog Devices ordering guide for verified substitute part numbers. Ensure any replacement maintains identical pin configurations, electrical specifications, and package dimensions to guarantee direct interchangeability without circuit redesign.

FAQ

Does the AD8606 exhibit output phase reversal?

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

What is the maximum input voltage range?

The input voltage range extends from the negative supply (GND) to the positive supply (VS), allowing full rail-to-rail common-mode operation.
