ADTL082ARZ-REEL7

Overview

The ADTL082ARZ-REEL7 is a dual-channel JFET input operational amplifier from Analog Devices, designed as an industry-standard replacement for the TL082. It operates within an extended industrial temperature range of -40°C to +125°C and utilizes an 8-lead SOIC package. Key electrical specifications include a gain bandwidth product of 5 MHz, a slew rate of 20 V/μs, and a maximum offset voltage of 5.5 mV. The device features low input bias current, unity-gain stability, and a typical supply current of 1.2 mA per amplifier.

Feature Summary

• JFET input architecture providing low noise and high input impedance
• Direct pin-compatible alternative to standard TL08x devices
• Extended industrial operating temperature range capability
• Unity-gain stable with low total harmonic distortion

Applications

• General-purpose signal amplification circuits
• Active filter design and implementation
• Industrial process control systems
• Data acquisition front-end conditioning
• Sample and hold circuit applications

Procurement Notes

Verify the specific grade suffix against the manufacturer's ordering guide to confirm the temperature range and RoHS compliance status. Ensure the reel quantity matches the production requirements. Confirm that the 8-lead SOIC footprint aligns with the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a direct upgrade to TL082 performance is required without altering the existing board footprint. The A-grade specification ensures suitability for harsh environments requiring operation down to -40°C. Consider the 5 MHz bandwidth limit when designing for high-frequency signal processing tasks.

Part Context

This device belongs to the ADTL08x family, which serves as a modernized successor to the legacy TL08x series. The family includes dual-channel (ADTL082) and quad-channel (ADTL084) variants. The ARZ suffix indicates the specific package type and manufacturing compliance, distinguishing it from older leaded or commercial-grade versions.

Replacement Considerations

Official substitutes include other ADTL082 variants such as ADTL082JRZ for commercial temperature ranges. Cross-referencing with TL082 datasheets confirms pin compatibility, though electrical parameters like offset voltage and bias current may differ between original and replacement grades.

FAQ

Does the ADTL082ARZ-REEL7 support single-supply operation?

Yes, the device supports single-supply operation, although the datasheet specifies performance characteristics typically measured with ±15 V dual supplies.

What is the maximum input bias current for this device?

The maximum input bias current is specified as 100 pA at 25°C, increasing to 5 nA across the full extended industrial temperature range.
