AD8622ARZ-REEL7

Overview

The AD8622ARZ-REEL7 is a dual precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output swing, low supply current of 215 µA per amplifier typical, and input bias current cancellation for very low bias current over the full operating temperature range. The device operates from ±2.5 V to ±15 V supplies and is specified for an extended industrial temperature range of −40°C to +125°C. Key electrical parameters include a maximum offset voltage of 125 µV, offset drift of 1.2 µV/°C, and voltage noise density of 11 nV/√Hz at 1 kHz.

Feature Summary

• Features input bias current cancellation circuitry providing very low input bias current across the full operating temperature range.
• Provides rail-to-rail output swing capability while maintaining unity gain stability.
• Designed with ultralow offset voltage and drift characteristics to minimize large error sources in precision applications.

Applications

• Portable precision instrumentation
• Laser diode control loops
• Strain gage amplifiers
• Medical instrumentation
• Thermocouple amplifiers

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the component meets RoHS compliance standards as indicated by the Z suffix in the base part number. Ensure the package type matches the footprint design specifications for the 8-lead SOIC_N configuration before finalizing procurement orders.

Selection Notes

Select this component when high dc precision and low power consumption are critical requirements. The dual channel configuration allows for cost-effective implementation of differential circuits or instrumentation amplifiers. Consider the rail-to-rail output feature if maximizing dynamic range within limited supply voltages is necessary for the system architecture.

Part Context

This component belongs to the AD8622/AD8624 family of low power, precision operational amplifiers. The AD8622 specifically provides two channels in an 8-lead SOIC package, whereas the AD8624 variant offers four channels in larger packages. Both share identical electrical performance characteristics regarding offset, noise, and power consumption profiles.

Replacement Considerations

The AD8622ARMZ serves as a pin-compatible alternative packaged in an 8-lead MSOP format. Other members of the AD862x family may offer similar electrical specifications but differ in channel count or physical dimensions.
