ADTL082ARMZ-REEL

Overview

The ADTL082ARMZ-REEL is a dual JFET input operational amplifier manufactured by Analog Devices Inc. It features an 8-lead MSOP package and operates within an extended industrial temperature range of -40°C to +125°C. Key electrical specifications include a gain-bandwidth product of 5 MHz, a slew rate of 20 V/μs, and a maximum offset voltage of 5.5 mV. The device offers low input bias current, unity-gain stability, and a typical supply current of 1.2 mA per amplifier.

Feature Summary

• JFET input stage providing high input impedance and low bias current
• Improved performance over standard TL08x devices with lower noise and offset drift
• Extended industrial temperature rating for reliable operation in harsh environments
• Unity-gain stable design suitable for direct feedback configurations

Applications

• Active filters requiring low distortion and wide bandwidth
• Industrial process control signal conditioning circuits
• Data acquisition systems needing high input impedance buffering
• Power control and monitoring applications
• Sample and hold circuit implementations

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 8-lead MSOP configuration. Confirm RoHS compliance status if required by assembly standards. Cross-reference the datasheet revision to validate all electrical parameters before final integration.

Selection Notes

Select this component when JFET input characteristics are preferred over bipolar or CMOS alternatives for minimal loading effects. Consider the 5 MHz bandwidth and 20 V/μs slew rate for general-purpose amplification tasks. Evaluate the extended temperature range requirements against commercial grade options. Compare total harmonic distortion specifications for audio or precision signal paths.

Part Context

This part belongs to the ADTL08x family, which serves as a modern replacement for legacy TL08x series amplifiers. The ADTL082 variant specifically provides two independent channels in a compact surface-mount package. It bridges the gap between cost-effective general-purpose op amps and higher-performance precision devices.

Replacement Considerations

Official substitutes include other members of the ADTL082 family such as ADTL082ARZ or ADTL082JRZ, depending on the required temperature range and packaging preference. Verify pinout compatibility and electrical parameter overlaps before substitution.
