AD8672TRZ-EP-R7

Overview

The AD8672TRZ-EP-R7 is a dual-channel precision operational amplifier from Analog Devices, packaged in an 8-lead SOIC (R-8) format. It features a gain bandwidth product of 10 MHz and a slew rate of 4 V/µs. The device operates on supply voltages ranging from ±5 V to ±15 V, with a maximum rating of 36 V. Key electrical specifications include a typical voltage noise density of 2.8 nV/√Hz, a peak-to-peak noise of 77 nV p-p, and a maximum input bias current of 14 nA. It maintains an offset voltage of up to 75 µV at 25°C and functions within an extended temperature range of −55°C to +125°C.

Feature Summary

• Enhanced Product qualification supporting defense and aerospace applications under AQEC standards.
• Ultralow noise performance with high precision and stability for capacitive loads exceeding 1000 pF.
• Extended industrial temperature operation spanning from −55°C to +125°C.

Applications

• Phase-locked loop (PLL) filters
• Filters for GPS systems
• Medical and analytical instrumentation
• Professional quality audio equipment

Procurement Notes

Verify the specific suffix R7 indicates tape and reel packaging configuration when sourcing. Confirm that the EP designation aligns with required Enhanced Product documentation and change notification protocols for your project. Ensure the manufacturer's datasheet is referenced for absolute maximum ratings and thermal resistance values before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring low power consumption alongside high precision and speed. The dual-channel architecture fits space-constrained PCB layouts using the standard narrow SOIC package. Consider the extended temperature range if the operating environment exceeds standard commercial limits. Verify that the 10 MHz bandwidth meets the signal processing requirements of the target application circuit.

Part Context

This part belongs to the AD8672-EP family of enhanced precision amplifiers manufactured by Analog Devices Inc. The EP variant specifically targets rugged environments requiring controlled manufacturing baselines and single-source fabrication sites. It shares core electrical characteristics with the standard AD8672 but includes additional qualification data available upon request for critical system deployments.

Replacement Considerations

Consult official substitution lists for verified equivalents. Generic replacements may not match the Enhanced Product reliability standards or the specific extended temperature range capabilities defined for this model.
