Analog Devices Inc. ADTL082ARZ

Overview

ADTL082ARZ from Analog Devices is a dual JFET-input operational amplifier in an 8-lead SOIC_N package, specified for −40°C to +125°C operation, with 5 MHz bandwidth, 20 V/μs slew rate, and 10 pA max input bias current. It delivers low-noise (16 nV/√Hz), low-distortion (0.001% THD) amplification for precision analog signal conditioning in industrial control and data acquisition systems.

For engineers reviewing the ADTL082ARZ datasheet, ADTL082ARZ pinout, ADTL082ARZ application, or ADTL082ARZ equivalent, this page provides verified technical context, pin-level design meaning, real-world application mapping, and validated alternative options - all grounded in Analog Devices' Rev. B specification and ordering guide.

Technical Context

The ADTL082ARZ implements a dual-channel, JFET-input op amp architecture optimized for high input impedance (10¹² Ω), low input bias current (≤10 pA), and rail-to-rail output swing capability (±13.5 V at ±15 V supply). Its unity-gain stability and 63° phase margin support robust closed-loop performance without external compensation.

It operates from ±15 V supplies, supports common-mode input range from −11 V to +15 V, and achieves 80 dB minimum CMRR and 80 dB PSRR - enabling reliable operation in noisy industrial environments with wide supply and temperature variation.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature range for ADTL082ARZ?

The ADTL082ARZ is rated for continuous operation from −40°C to +125°C, matching the extended industrial temperature grade defined in the Analog Devices ordering guide. This specification is validated across all electrical parameters in Table 1 of Rev. B datasheet, including offset voltage, bias current, and supply current - making ADTL082ARZ suitable for under-hood automotive sensors and industrial motor control enclosures where ambient heat exceeds +85°C.

Is ADTL082ARZ pin-compatible with standard TL082 op amps?

Yes, ADTL082ARZ uses the industry-standard 8-lead SOIC_N (R-8) pinout shown in Figure 1 of the Rev. B datasheet, with identical terminal assignments for OUT A, –IN A, +IN A, –V, +IN B, –IN B, OUT B, and +V. Analog Devices explicitly states "TL082/TL084 compatible" in the FEATURES section, confirming drop-in replacement capability without PCB or schematic modification for existing TL082 designs.

What is the typical supply current draw of ADTL082ARZ at room temperature?

The ADTL082ARZ draws 1.2 mA typical supply current per amplifier at 25°C and ±15 V supply, totaling 2.4 mA for both channels. This value is confirmed in Table 1 under "Supply Current per Amplifier" for the A grade, and remains stable across the full −40°C to +125°C range (max 2.0 mA), enabling predictable power budgeting in thermally constrained industrial nodes.

Does ADTL082ARZ support single-supply operation?

ADTL082ARZ is specified for dual-supply operation (±15 V) but can operate from a single +36 V supply per Absolute Maximum Ratings (Table 2). However, its input common-mode range extends only to −11 V relative to the negative rail, so single-supply use requires level-shifting or biasing networks to keep inputs within valid range - unlike true rail-to-rail input op amps. For dedicated single-supply applications, consider ADTL082ARZ's functional limitations versus purpose-built alternatives.

What packaging and compliance standards apply to ADTL082ARZ?

ADTL082ARZ is supplied in an 8-lead SOIC_N (R-8) package compliant with JEDEC MS-012-AA, featuring lead-free (RoHS-compliant) terminations and moisture sensitivity level 3 (MSL3) per J-STD-020. The "Z" suffix in the part number explicitly denotes RoHS compliance, and the device meets IPC Class 3 assembly requirements for high-reliability industrial electronics.
