AD8643TRZ-EP

Overview

The AD8643TRZ-EP is a low power, precision JFET input quad operational amplifier featuring rail-to-rail output. It supports single-supply operation from 5 V to 26 V and dual-supply operation from ±2.5 V to ±13 V. The device offers a maximum supply current of 250 μA per amplifier, a maximum input bias current of 1 pA, and a maximum offset voltage of 750 μV at 25°C. It operates over a military temperature range of −55°C to +125°C.

Feature Summary

• Supports defense and aerospace applications under the AQEC standard with controlled manufacturing baseline
• Features extremely low input bias current and low offset voltage for high precision
• Provides rail-to-rail output capability while maintaining unity-gain stability

Applications

• Line- or battery-powered instruments
• Photodiode amplifiers
• Precision current sensing
• Portable audio equipment

Procurement Notes

Verify that the specific part number matches the required military temperature range and package type. Confirm compliance with the AQEC standard if defense or aerospace qualification data is necessary. Ensure the ordering suffix corresponds to the correct reel configuration for surface-mount assembly processes.
