ADTL082ARMZ

Overview

The ADTL082ARMZ is a dual JFET input operational amplifier manufactured by Analog Devices, housed in an 8-lead Mini Small Outline Package (MSOP). It serves as an enhanced replacement for the industry-standard TL082, offering superior electrical characteristics including lower noise and offset voltage. The device operates within an extended industrial temperature range of −40°C to +125°C. Key performance metrics include a gain bandwidth product of 5 MHz, a slew rate of 20 V/μs, and a maximum input bias current of 100 pA. It features unity-gain stability and low supply current consumption.

Feature Summary

• JFET input architecture providing high input impedance and low bias current
• Enhanced precision specifications compared to standard TL08x devices
• Extended industrial operating temperature range capability
• Unity-gain stable design suitable for direct feedback configurations

Applications

• General-purpose signal amplification circuits
• Active filter designs requiring wide bandwidth
• Industrial process control systems
• Data acquisition front-end conditioning
• Precision integrator and differentiator circuits

Procurement Notes

Verify the specific grade designation associated with the ordering suffix to ensure compliance with required offset voltage and temperature range specifications. Confirm package availability and lead times directly with authorized distributors or the manufacturer. Ensure proper ESD handling procedures are followed during storage and assembly due to the sensitivity of the JFET input stage.

Selection Notes

Select this component when upgrading from legacy TL082 designs to achieve improved noise performance and tighter offset voltage tolerances without changing pin compatibility. Consider the MSOP package constraints regarding thermal dissipation and board space. Evaluate the 5 MHz bandwidth against application frequency requirements to ensure adequate phase margin and signal fidelity.

Part Context

This part belongs to the ADTL08x family, which represents Analog Devices' modernized iteration of classic JFET op-amps. The family includes single, dual, and quad variants designed to maintain pin-out compatibility with older generations while delivering better DC and AC performance. The ARMZ suffix indicates the MSOP package variant within this broader product line.

Replacement Considerations

Direct pin-compatible replacements include the ADTL082ARZ for SOIC packaging. For applications requiring higher precision, consider the ADA4610 series. General purpose JFET alternatives like the TL072 offer similar form factors but may lack the specific extended temperature guarantees of the ADTL082ARMZ.

FAQ
