ADTL082JR

Overview

The ADTL082JR is a dual-channel JFET input operational amplifier from Analog Devices, designed as an industry alternative to standard TL08x devices. It operates within the commercial temperature range of 0°C to +70°C and features a maximum offset voltage of 9 mV with a typical supply current of 1.2 mA per amplifier. Key performance metrics include a gain bandwidth product of 5 MHz, a slew rate of 20 V/μs, and low noise density of 16 nV/√Hz. The device offers high common-mode rejection and unity-gain stability.

Feature Summary

• Compatible with TL082/TL084 pinouts and functionality
• Low input bias current of 10 pA maximum
• Unity-gain stable for versatile circuit configurations
• Low total harmonic distortion of 0.001%

Applications

• General-purpose amplification circuits
• Active filter designs requiring wide bandwidth
• Industrial and process control signal conditioning
• Data acquisition systems and sample and hold circuits
• Integrators and input buffering stages

Procurement Notes

Verify the specific ordering suffix to confirm packaging format, such as tube or reel quantities, as these affect handling and storage requirements. Ensure the selected variant matches the required operating temperature range, noting that the JR grade is specified for commercial temperatures only. Confirm RoHS compliance status based on the presence of the Z suffix in the part number.

Selection Notes

Select the ADTL082JR when cost-effective JFET input performance is needed for commercial applications. Choose this model over the A grade if operation within the extended industrial temperature range is not required. Consider the package options available for the JR grade, primarily the 8-lead SOIC_N, to fit board space constraints while maintaining compatibility with existing TL08x footprints.

Part Context

The ADTL082JR belongs to the ADTL08x family, which provides improved specifications over traditional TL08x amplifiers, including lower noise and better common-mode rejection. This specific part represents the standard grade version intended for commercial environments, contrasting with the A grade variant designed for extended industrial temperature ranges.

Replacement Considerations

The datasheet identifies the ADTL082JR as an industry alternative to TL08x standard and C grades. Designers may consider direct replacements from other manufacturers offering TL082-compatible parts, ensuring that input bias current and offset voltage specifications meet the original design requirements.
