AD8627AKSZ-R2

Overview

The AD8627AKSZ-R2 is a precision single-supply JFET input amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage of 5 V to 26 V or dual supplies of ±2.5 V to ±13 V. The device features a 5 MHz gain bandwidth product, a slew rate of 5 V/µs, and a maximum offset voltage of 0.5 mV at 25°C. Input bias current is typically 0.25 pA with a maximum of 1 pA. Supply current is less than 630 µA per amplifier. The output stage provides rail-to-rail swing and remains stable with capacitive loads exceeding 500 pF.

Feature Summary

• JFET input architecture providing extremely low input bias current for high-impedance signal sources
• True single-supply operation capability with input common-mode range extending below the negative rail
• Rail-to-rail output stage maximizing dynamic range in low-voltage systems
• Unity gain stability ensuring reliable performance in buffer configurations without phase reversal

Applications

• Photodiode transimpedance amplification
• ATE reference level drivers
• Battery management systems
• Remote sensor signal conditioning including automotive sensors
• Precision active filters

Procurement Notes

Verify that the ordering suffix KSZ corresponds to the SC-70 package configuration and R2 indicates tape and reel packaging. Confirm the component meets RoHS compliance standards as specified in the manufacturer documentation. Ensure the industrial temperature rating aligns with system requirements before finalizing procurement orders.

Selection Notes

Select this component when picoampere-level input currents are critical to minimize errors across high-value feedback resistors. The wide single-supply voltage range accommodates various power architectures. Verify that the 5 MHz bandwidth satisfies the required signal frequency response and settling time constraints for the specific application design.

Part Context

This part belongs to the AD862x family of precision amplifiers, which includes the dual-channel AD8626 and quad-channel AD8625 variants. All members share identical electrical characteristics but differ in channel count and available package types such as SOIC, MSOP, and TSSOP. The AD8627 specifically denotes the single-channel version optimized for space-constrained designs.

Replacement Considerations

Direct functional substitutes within the same family include the AD8626ARZ and AD8625ARZ, provided additional channels are acceptable. Cross-family replacements require matching JFET input bias current specifications and rail-to-rail output capabilities.
