Overview
The AD8626ARZ is a dual precision 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, low supply current of 630 μA per amplifier, and a maximum offset voltage of 500 μV. Key electrical parameters include a gain-bandwidth product of 5 MHz, a slew rate of 5 V/μs, and an input bias current of 1 pA maximum. It operates within the industrial temperature range of -40°C to +85°C.
Feature Summary
- Features true single-supply capability with input voltage range extending below the negative rail.
- Provides rail-to-rail output swing for maximum dynamic range in single-supply systems.
- Maintains stability with capacitive loads exceeding 500 pF.
Applications
- Photodiode transimpedance amplification
- ATE reference level drivers
- Battery management systems
- Remote sensor signal conditioning including automotive sensors
Procurement Notes
Verify the specific package suffix 'R-8' corresponds to the 8-Lead SOIC configuration required for your PCB layout. Confirm that the component meets RoHS compliance standards if applicable to your manufacturing process. Ensure proper handling precautions are observed due to the sensitivity of the JFET input stage to electrostatic discharge during assembly.
Selection Notes
Select this component when picoampere-level input bias currents are critical for minimizing errors in high-impedance source applications. The rail-to-rail output allows for full utilization of the supply voltage range, making it suitable for low-voltage single-supply designs where maximizing signal swing is necessary.
Part Context
The AD8626ARZ belongs to the AD862x family of precision low-power single-supply JFET amplifiers. This series includes the AD8625 (quad) and AD8627 (single). The AD8626 specifically provides two channels in surface-mount packages, offering a balance between channel count and physical footprint for compact instrumentation designs.
Replacement Considerations
The AD8626ARMZ serves as a pin-compatible alternative in the MSOP package. Other members of the AD862x family share similar electrical characteristics but differ in channel count or package type.
