ADA4627-1BRZ-RL

Overview

The ADA4627-1BRZ-RL is a single-channel JFET operational amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 19 MHz and a slew rate of 82 V/µs. The device operates on dual supplies ranging from ±5 V to ±15 V with a supply current of 7 mA. Key electrical specifications include a maximum input offset voltage of 200 µV, an input bias current of 5 pA, and a voltage noise density of 6.1 nV/√Hz at 1 kHz. It provides rail-to-rail output swing and is housed in an 8-lead SOIC package.

Feature Summary

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

Applications

• High impedance sensors
• Photodiode amplifiers
• Precision instrumentation
• Phase-locked loop filters
• Medical equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific BRZ suffix indicates the A-grade offset voltage variant within the SOIC-8 package. Ensure the reel packaging matches design requirements. Check for RoHS compliance documentation prior to integration into production lines.

Selection Notes

Select this component for designs requiring both high bandwidth and low offset voltage. The unity-gain stability simplifies circuit configuration compared to decompensated variants. Consider PCB layout techniques such as guarding to maintain the specified low bias current performance. Evaluate thermal resistance if operating near extended temperature limits.

Part Context

This part belongs to the ADA4627/ADA4637 series of wide bandwidth precision amplifiers. It serves as the fully compensated, unity-gain stable counterpart to the decompensated ADA4637-1. Both devices share similar low noise and low drift characteristics but differ in stability requirements and gain bandwidth products.
