ADTL084ARUZ-REEL

Overview

The ADTL084ARUZ-REEL 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 on ±15 V supplies with a maximum offset voltage of 9 mV and low input bias current of 10 pA. Packaged in a 14-lead TSSOP, it offers unity-gain stability and low noise performance suitable for precision analog signal processing applications.

Feature Summary

• JFET input architecture providing low input bias current
• Compatible with industry standard TL084 pinouts and functionality
• Unity-gain stable design ensuring reliable feedback loop operation
• Low voltage noise density for high-fidelity signal amplification

Applications

• Active filters requiring wide bandwidth and low distortion
• Industrial and process control instrumentation systems
• Data acquisition front-end buffering stages
• Sample and hold circuit implementations
• Power control and monitoring signal conditioning

Procurement Notes

Verify the specific grade suffix to confirm temperature range compliance. The 'A' grade supports extended industrial temperatures while other grades may differ. Ensure the reel packaging matches the required quantity for production runs. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when JFET input impedance is required alongside TL084 compatibility. Consider the A grade variant for operations extending beyond commercial temperature limits. Evaluate the 5 MHz bandwidth against higher-speed alternatives if frequency response requirements exceed specifications. Check supply current consumption against low-power system constraints.

Part Context

This part belongs to the ADTL08x family, which improves upon the legacy TL08x series by offering lower noise, reduced offset voltage, and better common-mode rejection ratios. The ADTL084 specifically integrates four independent amplifiers into a single package, consolidating multiple discrete solutions into a compact footprint for space-constrained designs.

Replacement Considerations

Direct functional replacements include the ADTL084JR for SOIC packages or the ADTL084ARMZ for MSOP configurations. Verify thermal resistance values when transitioning between different package types to ensure adequate heat dissipation under maximum load conditions.
