AD8682ARMZ-REEL

Overview

The AD8682ARMZ-REEL is a dual low power, high speed JFET operational amplifier manufactured by Analog Devices Inc. It features a maximum supply current of 250 μA per amplifier and a typical slew rate of 9 V/μs. The device offers a gain bandwidth product of 3.5 MHz and a maximum input offset voltage of 1 mV at 25°C. Input bias current is typically 20 pA, rising to a maximum of 125 pA across the operating temperature range. It operates on supply voltages from ±4.5 V to ±18 V and is housed in an 8-lead MSOP package.

Feature Summary

• JFET input stage ensures extremely low input bias current for high source impedance applications
• Unity-gain stable with fast settling time and high slew rate for dynamic signal processing
• Optimized for low power consumption while maintaining high-speed performance characteristics

Applications

• Portable telecommunications equipment
• Low power industrial instrumentation
• Active and precision filters
• Strain gauge amplifiers
• Supply current monitoring

Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the required RoHS compliance status indicated by the Z suffix. Cross-reference the pinout configuration for the 8-lead MSOP package to guarantee compatibility with the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require both high bandwidth and low quiescent current consumption. The JFET input architecture makes it suitable for interfacing with high-impedance sensors where minimal loading is critical. Consider the common-mode voltage range limitations relative to the positive supply rail when choosing between this and rail-to-rail input alternatives.

Part Context

This part belongs to the AD8682/AD8684 family of precision amplifiers designed for battery-powered applications. The AD8682 variant provides two independent amplifiers in a single package, offering a compact solution for dual-channel signal conditioning tasks within portable electronic devices requiring efficient power management.

Replacement Considerations

Consult the manufacturer's ordering guide for direct package variations such as the SOIC_N version (AD8682ARZ) or different reel quantities. Verify thermal resistance values if transitioning between MSOP and SOIC packages to ensure adequate heat dissipation under identical load conditions.
