ADTL084ARUZ

Overview

The ADTL084ARUZ is a quad JFET input operational amplifier from Analog Devices, designed as an industry-standard replacement for the TL084. It features a 5 MHz gain bandwidth product and a 20 V/µs slew rate. The device operates with ±15 V supplies and maintains low noise at 16 nV/√Hz. It offers a maximum offset voltage of 5.5 mV and input bias current of 10 pA. Packaged in a 14-lead TSSOP, it supports extended industrial temperature ranges.

Feature Summary

• JFET input architecture providing high input impedance
• Compatible with standard TL08x pinouts and functionality
• Low noise performance suitable for precision applications
• Unity-gain stable design for general-purpose use

Applications

• Active filters
• Data acquisition systems
• Industrial process control
• Sample and hold circuits
• Input buffering

Procurement Notes

Verify the specific grade suffix to confirm the operating temperature range. The 'A' designation indicates extended industrial specifications, while other grades may differ. Ensure the package option matches the required footprint. Confirm RoHS compliance status based on the ordering guide details provided by the manufacturer.

Selection Notes

Select this component when replacing legacy TL084 designs requiring improved offset voltage and bias current characteristics. The quad configuration reduces board space compared to single-channel alternatives. Consider the 14-lead TSSOP package constraints for thermal management and layout requirements during the design phase.

Part Context

This device belongs to the ADTL08x family, which serves as an enhanced alternative to the classic TL08x series. The family includes dual-channel variants like the ADTL082. These amplifiers bridge the gap between cost-effective general-purpose op amps and higher-performance precision devices, offering better drift and noise specs than standard JFET inputs.

Replacement Considerations

Direct replacements include the ADTL084JR for commercial temperature ranges or other TL084-compatible parts if performance margins allow. Verify that substitute components match the 14-lead TSSOP outline dimensions and pinout assignments to ensure mechanical compatibility.

FAQ

What is the maximum supply voltage for the ADTL084ARUZ?

The absolute maximum rating allows for ±18 V or +36 V total supply voltage.

Does the ADTL084ARUZ support rail-to-rail output?

No, the datasheet specifies a maximum output voltage swing of approximately ±13.5 V under typical conditions, not reaching the full supply rails.
