Product details
Overview
ADTL082ARZ-REEL from Analog Devices is a dual JFET-input operational amplifier optimized 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 supply operation, and 5.5 mV maximum offset voltage (A grade), enabling high-fidelity amplification in active filters, data acquisition front-ends, and sensor signal chains.
For engineers reviewing the ADTL082ARZ-REEL datasheet, ADTL082ARZ-REEL pinout, ADTL082ARZ-REEL application, or ADTL082ARZ-REEL equivalent, this page provides verified package mapping (SOIC_N R-8), temperature-rated performance (−40°C to +125°C), JFET-input advantages (10 pA max input bias current), and direct TL082-compatible replacement guidance for legacy design upgrades.
Technical Context
The ADTL082ARZ-REEL implements a dual-channel, JFET-input op amp architecture with unity-gain stability and rail-to-rail output swing capability up to ±13.5 V into 10 kΩ. Its differential input stage achieves 86 dB minimum CMRR and 86 dB PSRR across the extended industrial temperature range.
It supports ±15 V dual-supply operation with 1.2 mA typical supply current per amplifier, low THD (0.001% at 1 kHz), and 120 dB channel separation at 10 kHz-making it suitable for multi-channel signal processing where crosstalk and distortion must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5 MHz - Enables stable closed-loop operation up to 5× gain at 1 MHz or unity gain at 5 MHz. |
| Slew Rate | 20 V/μs - Supports fast transient response in pulse amplification and active filter applications. |
| Input Bias Current | 10 pA maximum - Minimizes DC error in high-impedance sensor interfaces (e.g., photodiode, piezoelectric). |
| Offset Voltage | 5.5 mV maximum (−40°C to +125°C) - Ensures low DC error in precision DC-coupled amplifiers and integrators. |
| Supply Voltage Range | ±15 V (±18 V absolute max) - Compatible with standard industrial bipolar supply rails without level-shifting. |
| Voltage Noise Density | 16 nV/√Hz at 1 kHz - Critical for low-noise preamplification of microvolt-level signals in instrumentation. |
| Common-Mode Rejection | 86 dB minimum - Maintains accuracy in noisy industrial environments with common-mode interference. |
Pinout & Package
ADTL082ARZ-REEL is housed in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and gull-wing leads. Thermal resistance θJA = 158°C/W enables operation up to +125°C ambient with appropriate PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A; drives loads ≥2 kΩ with ±13 V swing. |
| 2 | –IN A | Inverting input of channel A; high-impedance JFET node (1012 Ω). |
| 3 | +IN A | Non-inverting input of channel A; matched to –IN A for optimal CMRR. |
| 4 | –V | Negative supply terminal; must be connected before input signals to prevent latch-up. |
| 5 | +IN B | Non-inverting input of channel B; electrically isolated from channel A. |
| 6 | –IN B | Inverting input of channel B; independent bias current path (≤10 pA). |
| 7 | OUT B | Output of channel B; fully specified for same dynamic and DC performance as OUT A. |
| 8 | +V | Positive supply terminal; requires simultaneous or prior establishment vs. inputs. |

Applications
| Active Filter Design | Data Acquisition Front-End |
|---|---|
Use Scenario: Second-order Sallen-Key low-pass filter for anti-aliasing before ADC sampling at 100 kSPS. IC Role / Device Role / Timing Role: Dual op amp configured as unity-gain buffer and filter integrator; channels A and B operate independently with <120 dB crosstalk. Use Value: 5 MHz GBW and 20 V/μs slew rate ensure phase linearity and step response fidelity up to 50 kHz cutoff. |
Use Scenario: Buffered differential input stage for 16-bit SAR ADC measuring thermocouple or strain gauge outputs. IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end with matched JFET inputs minimizing offset drift over temperature. Use Value: 5.5 mV max VOS and 10 μV/°C drift maintain <0.1% measurement accuracy across −40°C to +125°C. |
| Industrial Process Control | Sensor Signal Conditioning |
Use Scenario: 4–20 mA loop transmitter output amplifier driving long cables in factory automation. IC Role / Device Role / Timing Role: Output driver with ±13.5 V swing into 10 kΩ load; supplies excitation current to field sensors. Use Value: 86 dB CMRR rejects common-mode noise from shared ground returns in distributed I/O systems. |
Use Scenario: High-impedance pH electrode interface requiring ultra-low input current and DC stability. IC Role / Device Role / Timing Role: Non-inverting amplifier with guard ring and T-network feedback; JFET inputs prevent electrode polarization. Use Value: 10 pA max IB avoids >1 mV error in 100 MΩ source impedance configurations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Higher 30 pA max input bias current; 9 mV max VOS; commercial 0°C to +70°C range only. | Limited to non-extended temperature applications; unsuitable for automotive or harsh industrial use. | Select when cost sensitivity outweighs temperature or precision requirements; verify layout compatibility. |
| OPA2134UA | Lower 0.8 pA IB, 2.5 mV VOS, but 8 MHz GBW and higher 4.5 mA supply current per channel. | Better precision and speed, but increased power dissipation limits use in thermally constrained modules. | Choose for ultra-low-noise, high-resolution systems where power budget allows; not pin-compatible. |
Compared with TL082CDR, ADTL082ARZ-REEL offers tighter offset, lower bias current, and extended temperature support; versus OPA2134UA, it trades some precision for lower quiescent current and full TL082 footprint compatibility-enabling seamless upgrade paths.

FAQ
What is the operating temperature range for ADTL082ARZ-REEL?
The ADTL082ARZ-REEL is rated for operation from −40°C to +125°C, meeting extended industrial temperature requirements. This specification is confirmed in the Ordering Guide and General Description sections of the Rev. B datasheet, where the "A" grade designation explicitly defines this range-distinct from the "J" grade's 0°C to +70°C limit. The device maintains all key parameters (e.g., offset voltage ≤5.5 mV, bias current ≤10 pA) across this full span.
Is ADTL082ARZ-REEL pin-compatible with standard TL082 devices?
Yes, ADTL082ARZ-REEL uses the same 8-lead SOIC_N (R-8) package and identical pinout as TL082, as shown in Figure 1 of the datasheet. Pin assignments (OUT A, –IN A, +IN A, –V, +IN B, –IN B, OUT B, +V) match TL082 exactly, enabling direct PCB-level replacement without layout modification. Functional compatibility is further validated by the "TL082/TL084 compatible" feature statement.
What are the absolute maximum supply voltage ratings for ADTL082ARZ-REEL?
The ADTL082ARZ-REEL has an absolute maximum supply voltage rating of ±18 V or +36 V total (Table 2, Absolute Maximum Ratings). Operation at ±15 V is recommended for normal use, delivering full performance including ±13.5 V output swing into 10 kΩ. Exceeding ±18 V risks permanent damage, and power sequencing guidelines require supplies to be established before input signals.
Does ADTL082ARZ-REEL support single-supply operation?
No, ADTL082ARZ-REEL is designed for dual-supply operation (±V) and does not support true single-supply functionality. Its input common-mode range extends to −11 V (with ±15 V supplies), and output swing is asymmetric around ground. For single-supply applications, a level-shifting reference or rail-to-rail input/output op amp would be required-ADTL082ARZ-REEL lacks internal charge pumps or dedicated single-supply bias circuitry.
What is the lead finish and RoHS status of ADTL082ARZ-REEL?
ADTL082ARZ-REEL features a lead-free (Pb-free) termination with matte tin plating, as indicated by the "Z" suffix in the part number per the Ordering Guide footnote ("1 Z = RoHS Compliant Part"). It complies with EU RoHS Directive 2011/65/EU and is qualified to JEDEC J-STD-020 moisture sensitivity level 3, supporting standard reflow profiles without special handling.
