AD8667ARMZ-REEL

Overview

The AD8667ARMZ-REEL is a dual precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and utilizes the patented DigiTrim® trimming technique to achieve low offset voltage. The device operates on single supplies from 5 V to 16 V or dual supplies of ±2.5 V to ±8 V. Key electrical specifications include a maximum supply current of 275 μA per amplifier, a gain bandwidth product of 540 kHz, and a slew rate of 0.3 V/μs at 16 V. It offers a voltage noise density of 23 nV/√Hz and an input bias current as low as 0.3 pA. The component is housed in an 8-lead MSOP package and is specified over an extended industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify that the ordering suffix -REEL corresponds to the reel packaging format rather than tube packaging when sourcing this specific part number. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the procurement channel provides valid traceability for the Analog Devices manufacturing lot. Cross-reference the datasheet revision to confirm the technical parameters match the specific production batch requirements.

Selection Notes

Select this component for applications requiring dual-channel precision amplification with low power consumption. The wide supply voltage range supports both single and dual supply architectures. Consider the 8-lead MSOP package dimensions for board space constraints. Evaluate the low input bias current against the source impedance of the signal chain to minimize error currents. Verify that the rail-to-rail output swing meets the input requirements of downstream components.

Part Context

This device belongs to the AD866x family of low noise, precision, 16 V CMOS rail-to-rail operational amplifiers. The family includes the single-channel AD8663 and the quad-channel AD8669. All variants share similar core technologies, including DigiTrim® trimming and low noise characteristics. The AD8667 specifically integrates two independent amplifiers into a compact package, offering a balanced solution for multi-channel signal conditioning tasks.

Replacement Considerations

The AD8667ARZ serves as a tube-packaged alternative within the same series. Other members of the AD866x family, such as the AD8663 and AD8669, offer different channel counts but share identical electrical characteristics and pinouts where applicable.
