ADA4627-1ARZ-RL

Overview

The ADA4627-1ARZ-RL is a single-channel JFET operational amplifier from Analog Devices, packaged in an 8-lead SOIC. It operates on dual supplies ranging from ±5 V to ±15 V (30 V total). Key electrical specifications include a gain-bandwidth product of 19 MHz and a slew rate of 82 V/µs. The device features a maximum input offset voltage of 200 µV with a typical drift of 1 µV/°C. Input bias current is limited to 5 pA maximum, and voltage noise density is 6.1 nV/√Hz at 1 kHz. It supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Combines high-speed AC performance with precision DC characteristics for low-noise applications.
• Features very low input bias current suitable for high-impedance sensor interfaces.
• Designed to prevent output phase reversal when inputs exceed the common-mode range.

Applications

• Photodiode amplifiers
• High impedance sensors
• Precision instrumentation

Procurement Notes

Verify the specific ordering suffix RL against the manufacturer's official documentation to confirm reel packaging requirements. Confirm that the component meets RoHS standards and check for any recent production change notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component for designs requiring both wide bandwidth and low offset voltage. Ensure the application maintains a noise gain of unity for stability. Consider PCB layout techniques such as guard rings to minimize leakage currents associated with the JFET input stage.

Part Context

This part belongs to the ADA4627-1/ADA4637-1 series of wide bandwidth precision amplifiers. The ADA4627-1 is unity-gain stable, whereas the ADA4637-1 is decompensated and requires a minimum noise gain of five. Both share similar core specifications but differ in frequency compensation.
