AD8672TRZ-EP

Overview

The AD8672TRZ-EP is a dual-channel precision operational amplifier from Analog Devices, designed for high-performance applications. It features a gain bandwidth product of 10 MHz and a slew rate of 4 V/µs. The device operates with supply currents of less than 3 mA per amplifier at 30 V. Key electrical specifications include a maximum input offset voltage of 75 µV and a maximum input bias current of 14 nA. It provides a typical voltage noise density of 2.8 nV/√Hz and peak-to-peak noise of 77 nV p-p. The component supports dual-supply operation from ±5 V to ±15 V and functions within an extended temperature range of −55°C to +125°C.

Procurement Notes

Verify the specific ordering suffix (e.g., -R7) against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the Enhanced Product designation meets all required qualification data and change notification protocols for your specific project constraints before finalizing procurement.

Selection Notes

Select this component when ultralow noise and high precision are critical requirements alongside wide bandwidth. Ensure the design accommodates the specified operating temperature range and power supply voltages. Verify that the package dimensions fit the available board space and that thermal management aligns with the specified junction temperature limits.

Part Context

This part belongs to the AD8672 family of very high precision amplifiers. The EP variant specifically denotes an Enhanced Product status, indicating controlled manufacturing baselines and single-site fabrication. This distinguishes it from standard commercial versions by offering enhanced traceability and stability suitable for rigorous industrial or military environments.

Replacement Considerations

Direct substitutes must match the 8-Lead SOIC package and dual-channel configuration. Verify compatibility regarding offset voltage, bias current, and noise specifications. Ensure any replacement maintains the same extended temperature rating and enhanced product reliability standards if required by the application.
