AD8667ARZ-REEL7

Overview

The AD8667ARZ-REEL7 is a dual precision CMOS operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and operates on supply voltages ranging from 5 V to 16 V, or ±2.5 V to ±8 V in dual-supply configurations. The device utilizes patented DigiTrim® technology to achieve low offset voltage, with a maximum of 300 µV at 16 V supply. Key electrical parameters include a gain bandwidth product of 540 kHz, a slew rate of 0.3 V/µs, and an input bias current as low as 0.3 pA. It provides a voltage noise density of 23 nV/√Hz at 1 kHz and maintains unity-gain stability. The component is housed in an 8-lead SOIC package and is specified for operation across the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Utilizes patented DigiTrim® trimming technique to achieve low input offset voltage and drift.
• Features extremely low input bias current suitable for high impedance sensor applications.
• Provides rail-to-rail output swing to maximize dynamic range when driving data converters.
• Operates on single or dual power supplies up to 16 V while maintaining low power consumption.

Applications

• Sensor front ends
• Transimpedance amplifiers
• Electrometer applications
• Photodiode amplification
• Medical diagnostic instruments

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to the specific reel packaging configuration required for your assembly line. Confirm the RoHS compliance status indicated by the Z suffix matches environmental regulations applicable to your region. Ensure the 8-lead SOIC package dimensions align with your PCB footprint design rules before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel amplifier is required with rail-to-rail output capabilities and low power consumption under higher voltage rails. It serves as a direct replacement for JFET amplifiers in systems demanding low input bias current without sacrificing bandwidth. Consider the 8-lead SOIC package constraints regarding thermal dissipation and board space availability during the schematic capture phase.

Part Context

This part 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, sharing identical core electrical characteristics and manufacturing processes. All variants utilize the same DigiTrim® technology and are designed for similar precision signal conditioning tasks within the extended industrial temperature range.

Replacement Considerations

The AD8667ARMZ is a pin-compatible alternative available in an 8-lead MSOP package. Verify that the mechanical footprint and thermal requirements of the target application support the MSOP form factor if substituting the SOIC version.
