Overview
The AD8627AR-REEL7 is a precision, low-power, single-supply JFET input operational amplifier manufactured by Analog Devices Inc. It features true single-supply operation from 5 V to 26 V and dual-supply operation from ±2.5 V to ±13 V. The device offers rail-to-rail output capability, low supply current of 630 μA per amplifier, and a maximum offset voltage of 500 μV. It provides a gain-bandwidth product of 5 MHz and a slew rate of 5 V/μs. The component is housed in an 8-lead SOIC package.
Feature Summary
- JFET input stage providing very low input bias current
- Rail-to-rail output swing for maximum dynamic range
- True single-supply operation with extended input common-mode range
- Unity gain stable without phase reversal near positive rail
Applications
- Photodiode transimpedance amplifiers
- Precision active filters
- Output buffering for CMOS DACs
- Portable battery-powered instrumentation
Procurement Notes
Verify the specific ordering suffix 'R' corresponds to the 8-lead SOIC package configuration required for your PCB layout. Confirm that the 'REEL7' designation indicates tape and reel packaging suitable for automated surface-mount assembly processes. Ensure compatibility with industrial temperature specifications ranging from -40°C to +85°C.
Selection Notes
Select this component when picoampere-level input bias currents are critical for minimizing errors in high-impedance sensor interfaces. The rail-to-rail output makes it suitable for single-supply systems requiring full signal swing. Consider its 5 MHz bandwidth for applications requiring faster settling times compared to older single-supply JFET amplifiers.
Part Context
The AD8627 is part of the AD862x family, which includes the quad-channel AD8625 and dual-channel AD8626. While sharing identical electrical characteristics and performance metrics, the AD8627 specifically contains one amplifier channel. This family is designed for precision applications requiring low power consumption and high input impedance.
Replacement Considerations
The AD8626 and AD8625 share identical electrical specifications and can serve as functional replacements if pin count and package availability allow. Verify that the alternative package type (MSOP or TSSOP) fits the existing footprint or allows for redesign.
