ADTL084ARZ-REEL

Overview

The ADTL084ARZ-REEL is a quad JFET input operational amplifier manufactured by Analog Devices Inc. It provides industry-leading performance over TL08x devices, featuring low noise of 16 nV/√Hz and wide bandwidth of 5 MHz. The device operates with ±15 V supplies, offers a slew rate of 20 V/μs, and maintains unity-gain stability. Designed for the extended industrial temperature range of −40°C to +125°C, it delivers high precision with maximum offset voltage of 5.5 mV and minimum CMRR of 80 dB.

Feature Summary

• Compatible with standard TL082/TL084 pinouts while offering superior electrical characteristics
• Features extremely low input bias current of 10 pA maximum for minimal signal loading
• Provides low voltage noise density of 16 nV/√Hz for high-fidelity signal processing
• Ensures stable operation across wide supply voltages up to ±18 V

Applications

• General-purpose amplification in instrumentation circuits
• Active filter design requiring precise frequency response
• Data acquisition systems needing low distortion
• Industrial process control signal conditioning
• Power control and monitoring applications

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status if environmental regulations apply to the manufacturing environment. Ensure the reel quantity aligns with production requirements before finalizing procurement orders.

Selection Notes

Select this component when upgrading from legacy TL08x designs without changing board layout. Choose the A-grade variant for extended industrial temperature ranges. Consider the REEL suffix for automated surface-mount assembly processes requiring continuous tape feeding.

Part Context

This part belongs to the ADTL08x family of low-cost JFET input amplifiers. It serves as an improved alternative to standard TL08x grades, offering better offset voltage, drift, and common-mode rejection. The quad configuration integrates four independent amplifiers into a single compact package for space-constrained designs.

Replacement Considerations

Direct replacements include other ADTL084 variants with matching temperature grades and packages. Verify pin compatibility with existing TL084 footprints during substitution. Ensure supply voltage limits remain within the new component's absolute maximum ratings.

FAQ

What is the maximum operating supply voltage for the ADTL084?

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

Is the ADTL084ARZ-REEL suitable for high-frequency applications?
