Product details
Overview
ADTL084ARZ-REEL from Analog Devices is a quad JFET-input operational amplifier designed for precision analog signal conditioning in industrial and instrumentation systems. It delivers 5 MHz gain bandwidth, 20 V/μs slew rate, 16 nV/√Hz input voltage noise, ±15 V dual-supply operation, and 80 dB minimum CMRR - enabling high-fidelity amplification in active filters, data acquisition front-ends, and sensor signal chains.
For engineers reviewing the ADTL084ARZ-REEL datasheet, ADTL084ARZ-REEL pinout, ADTL084ARZ-REEL application, or ADTL084ARZ-REEL equivalent, key selection considerations include its −40°C to +125°C extended temperature rating, 14-lead SOIC_N (R-14) package, low 10 pA max input bias current, and TL084-compatible pinout for drop-in upgrades in legacy designs.
Technical Context
The ADTL084ARZ-REEL integrates four independent JFET-input op amps with unity-gain stability, rail-to-rail output swing capability (±13.5 V into 10 kΩ), and matched internal characteristics across channels. Its architecture minimizes input offset drift (10 μV/°C max) and total harmonic distortion (0.001% at 1 kHz), supporting accurate DC-coupled and wideband AC signal processing.
Designed as an enhanced replacement for TL084, it improves upon offset voltage (5.5 mV max vs. 9 mV for J-grade), noise, CMRR, and slew rate while maintaining pin compatibility with industry-standard SOIC-14 footprints. The device operates from ±5 V to ±18 V supplies and features 10¹² Ω input impedance for high-impedance source interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5 MHz - supports stable closed-loop operation up to 5×10⁶ Hz with unity gain, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 20 V/μs - enables faithful reproduction of fast-rising signals (e.g., pulse trains, step responses) without slew-induced distortion. |
| Input Voltage Noise Density | 16 nV/√Hz at 1 kHz - ensures minimal added noise in low-level sensor amplification (e.g., thermocouples, strain gauges). |
| Input Bias Current | 10 pA maximum - preserves signal integrity when driving high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Common-Mode Rejection Ratio | 80 dB minimum - rejects interference common to both inputs, critical for differential measurements in noisy industrial environments. |
| Supply Current per Amplifier | 1.2 mA typical - allows four-channel operation within tight power budgets (e.g., <5 mA total for battery-powered DAQ modules). |
| Operating Temperature Range | −40°C to +125°C - qualified for under-hood automotive, motor control feedback, and factory-floor embedded systems. |
Pinout & Package
ADTL084ARZ-REEL is housed in a 14-lead SOIC_N (R-14) package per JEDEC MS-012-AB, with 1.27 mm lead pitch, 8.75 mm × 4.00 mm body dimensions, and exposed copper pad not present (standard plastic SOIC). Thermal resistance θJA = 120°C/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDR | Higher 9 mV max offset voltage, 3 nA max input bias current, commercial 0°C to +70°C rating, same R-14 package. | Limited to benign environments; unsuitable for extended temperature or ultra-low bias current requirements. | Select TL084CDR only for cost-sensitive, non-automotive, room-temperature applications where offset and bias specs are relaxed. |
| OPA4134UA | Lower 0.5 mV max offset, 10 fA bias current, 8 MHz GBW, but higher 4.5 mA supply current and no TL084 pin compatibility. | Requires PCB layout change; better for ultra-precision audio or metrology, not drop-in TL084 upgrade. | Choose OPA4134UA when ultimate DC accuracy and noise performance outweigh pin-compatibility and power constraints. |
Compared with TL084CDR, ADTL084ARZ-REEL offers tighter offset, lower bias current, and extended temperature operation - making it superior for industrial upgrades. Versus OPA4134UA, it trades some precision for pin compatibility, lower power, and broader ambient tolerance - ideal for retrofitting legacy systems without board revision.

FAQ
Is ADTL084ARZ-REEL pin-compatible with the TL084?
Yes, ADTL084ARZ-REEL uses the same 14-lead SOIC_N (R-14) package and identical pinout as the TL084, enabling direct replacement in existing designs without PCB modification. This includes matching assignments for all four amplifier inputs/outputs and dual supply pins.
What is the maximum operating temperature range for ADTL084ARZ-REEL?
The ADTL084ARZ-REEL is rated for operation from −40°C to +125°C, qualifying it for extended industrial and automotive under-hood applications. This exceeds the 0°C to +70°C range of standard TL084J-grade devices.
Does ADTL084ARZ-REEL require external compensation for unity-gain stability?
No, ADTL084ARZ-REEL is internally compensated and unity-gain stable. It can be used in buffer, follower, or gain-of-one configurations without adding external capacitors or resistors - simplifying circuit design and reducing bill-of-materials count.
Can ADTL084ARZ-REEL operate from a single supply?
ADTL084ARZ-REEL is optimized for dual-supply operation (±5 V to ±18 V), but can function on single-ended supplies (e.g., +10 V and GND) with appropriate input common-mode and output swing constraints. Input voltage range extends to −11 V, so GND-referenced use requires level-shifting or rail-splitting networks.
What is the typical supply current consumption of ADTL084ARZ-REEL?
The ADTL084ARZ-REEL draws 1.2 mA per amplifier at 25°C and ±15 V supplies, totaling 4.8 mA for all four channels. This remains stable across temperature, with a maximum of 2.0 mA per amplifier at +125°C - supporting low-power portable instrumentation designs.
