AD8672AR-REEL7

Overview

The AD8672AR-REEL7 is a dual-channel precision operational amplifier from Analog Devices, housed in an 8-lead SOIC package. It features a gain bandwidth product of 10 MHz and a slew rate of 4 V/µs. The device operates on dual supplies ranging from ±5 V to ±15 V with a supply current of approximately 3 mA per amplifier. Key electrical specifications include a maximum input offset voltage of 75 µV, a maximum input bias current of 12 nA, and a voltage noise density of 2.8 nV/√Hz at 1 kHz.

Feature Summary

• Very low voltage noise density for high-fidelity signal processing
• Low input bias current suitable for high-impedance sources
• Capable of driving capacitive loads exceeding 1000 pF without instability
• Unity-gain stable with no phase reversal upon overdrive

Applications

• PLL filters
• Filters for GPS systems
• Instrumentation
• Sensors and controls
• Professional quality audio

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and RoHS compliance status. Ensure the component matches the required temperature range and pinout configuration before integration into the design.

Selection Notes

Select this component when low noise and high precision are critical requirements. The wide bandwidth and stability under capacitive loads make it suitable for demanding analog signal paths where minimal distortion and accurate amplification are necessary.

Part Context

This part belongs to the AD8671/AD8672/AD8674 series of very high precision amplifiers. The AD8672 variant specifically provides two independent channels within a single compact package, offering board space efficiency compared to comparable discrete solutions.

Replacement Considerations

Consult the manufacturer's ordering guide for direct equivalents such as the AD8672ARMZ or other variants within the same family that share identical electrical characteristics and functionality.
