ADTL082JRZ

Overview

The ADTL082JRZ is a dual JFET input operational amplifier from Analog Devices, designed as an industry alternative to standard TL08x devices. It operates within a 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 5 MHz gain-bandwidth product, a 20 V/μs slew rate, and low noise density of 16 nV/√Hz. The device is housed in an 8-lead SOIC package and offers unity-gain stability for general-purpose amplification tasks.

Feature Summary

• Compatible with TL082/TL084 pinouts while offering superior bias current and noise performance
• Low input bias current of 10 pA maximum for high impedance applications
• Unity-gain stable design ensuring reliable operation in feedback configurations
• Total harmonic distortion of 0.001% for high-fidelity signal processing

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 procedures. Ensure the commercial temperature grade meets your environmental requirements. Confirm RoHS compliance status if lead-free construction is mandatory for your assembly process. Cross-reference the datasheet revision to ensure all electrical specifications align with your design constraints.

Selection Notes

Select this component when upgrading from legacy TL08x parts to achieve lower offset voltage and bias current without changing the footprint. Consider the ADTL082ARZ variant if extended industrial temperature operation is required. Evaluate the power supply rejection ratio and common-mode rejection ratio against your system's noise immunity needs. Verify that the output swing capabilities meet your load requirements under expected operating conditions.

Part Context

This device belongs to the ADTL08x family, which provides enhanced performance over traditional JFET op-amps. The 'J' grade specifically targets cost-sensitive applications while maintaining better accuracy than standard TL082 equivalents. It serves as a direct drop-in replacement for many TL082 designs, offering improved drift characteristics and higher slew rates for dynamic signal applications.

Replacement Considerations

The ADTL082ARZ is the extended temperature version of this part. Direct functional replacements include other JFET input dual op-amps with similar pinouts, though electrical parameters may vary significantly.
