Product details
Overview
ADTL082ARMZ-REEL from Analog Devices is a dual JFET-input operational amplifier in 8-lead MSOP package, specified for −40°C to +125°C operation, with 5 MHz gain bandwidth, 20 V/μs slew rate, and 10 pA maximum input bias current. It serves as a precision signal conditioning and buffering stage in industrial sensor interfaces and data acquisition front-ends.
For engineers reviewing the ADTL082ARMZ-REEL datasheet, ADTL082ARMZ-REEL pinout, ADTL082ARMZ-REEL application, or ADTL082ARMZ-REEL equivalent, this page delivers verified electrical parameters, thermal performance data, package-specific layout guidance, and validated alternative options for high-reliability analog signal chains.
Technical Context
The ADTL082ARMZ-REEL implements a dual-channel JFET-input architecture optimized for low input bias current (≤10 pA) and low voltage noise (16 nV/√Hz at 1 kHz), enabling high-impedance source interfacing without significant DC error or noise degradation. Its ±15 V supply capability and 80 dB minimum CMRR support robust operation in noisy industrial environments.
It features unity-gain stability, 5.5 mV maximum offset voltage (A grade), and 10 μV/°C offset drift over temperature - characteristics critical for active filtering, integrator circuits, and precision instrumentation amplifiers where long-term DC accuracy is required.
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 accurate reproduction of fast-rising signals up to ~3.2 V peak at 1 MHz without distortion. |
| Input Bias Current | 10 pA max - minimizes voltage error across high-value feedback or sensor resistors (>10 MΩ), preserving signal integrity. |
| Offset Voltage | 5.5 mV max - ensures ≤5.5 mV DC error at output under no-signal conditions, critical for DC-coupled measurement paths. |
| Supply Current per Amplifier | 1.2 mA typical - allows dual-amplifier operation within 2.4 mA total, supporting low-power industrial modules. |
| Common-Mode Rejection Ratio | 80 dB min - rejects up to 10⁴× common-mode interference, essential for differential sensing in motor drive or power monitoring. |
| Operating Temperature Range | −40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor embedded systems without derating. |
Pinout & Package
ADTL082ARMZ-REEL uses an 8-lead MSOP (RM-8) package with exposed pad, measuring 3.0 mm × 3.0 mm × 0.85 mm (max height). Thermal resistance θJA = 210°C/W and θJC = 45°C/W enable reliable operation at full rated load in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output channel A; drives loads ≥2 kΩ with ±12.5 V swing at ±15 V supply. |
| 2 | –IN A | Inverting input of channel A; high-impedance JFET node (RIN = 10¹² Ω) for precision feedback networks. |
| 3 | +IN A | Non-inverting input of channel A; matched to –IN A for balanced common-mode rejection. |
| 4 | –V | Negative supply rail connection; must be established before input signals to prevent latch-up. |
| 5 | +IN B | Non-inverting input of channel B; electrically isolated from channel A but shares same die substrate. |
| 6 | –IN B | Inverting input of channel B; identical bias and noise specs to channel A for matched dual-channel designs. |
| 7 | OUT B | Inverting amplifier output channel B; independent output stage with same dynamic performance as OUT A. |
| 8 | +V | Positive supply rail connection; supports ±15 V or single +30 V operation with proper decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | 10 pA max enables use with >100 MΩ feedback resistors in electrometer-grade sensor interfaces. |
| Low Noise Performance | 16 nV/√Hz at 1 kHz supports high-resolution audio and precision data acquisition without added noise floor. |
| Extended Temperature Range | −40°C to +125°C operation eliminates need for external thermal compensation in harsh-environment control systems. |
| TL082-Compatible Pinout | Direct drop-in replacement for legacy TL082 designs in SOIC-8 footprints; MSOP variant requires board revision. |
| Unity-Gain Stable | No external compensation required for gain ≥1 configurations, simplifying active filter and buffer design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Higher 200 pA input bias current, 15 mV max offset, 0°C to +70°C only, SOIC-8 only. | Limited to commercial-temperature consumer or lab equipment; unsuitable for automotive or industrial control. | Select when cost sensitivity outweighs precision and temperature range requirements. |
| OPA2134UA | Lower 10 fA bias current, 2.5 mV max offset, 8 MHz GBW, but higher 4 mA supply current and $2.50+ unit price. | Better suited for ultra-low-noise audio or metrology; less optimal for battery-powered or thermally constrained modules. | Select when sub-mV offset and femtoampere bias are mandatory, and power budget allows 2× current draw. |
Compared with TL082CDR, ADTL082ARMZ-REEL delivers 20× lower input bias and extended temperature range at similar cost; versus OPA2134UA, it trades 30% higher bias current for 50% lower supply current and broader industrial qualification - making it optimal for cost-sensitive, thermally demanding analog front-ends.

FAQ
What is the maximum operating junction temperature for ADTL082ARMZ-REEL?
The ADTL082ARMZ-REEL has a maximum junction temperature rating of 150°C, consistent with its −40°C to +125°C ambient operating range and 45°C/W junction-to-case thermal resistance in the MSOP package. This allows sustained operation at full electrical specifications under typical PCB copper pour and airflow conditions.
Does ADTL082ARMZ-REEL require external compensation for unity-gain stability?
No, ADTL082ARMZ-REEL is internally compensated for unity-gain stability. It can be used in voltage follower, inverting amplifier, or non-inverting amplifier configurations with gain ≥1 without external capacitors or resistor networks - simplifying layout and reducing bill-of-materials count.
Is ADTL082ARMZ-REEL RoHS compliant and lead-free?
Yes, ADTL082ARMZ-REEL is RoHS compliant and manufactured with lead-free terminations. The "Z" suffix in the part number confirms compliance, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at standard humidity conditions.
Can ADTL082ARMZ-REEL operate on a single +30 V supply?
Yes, ADTL082ARMZ-REEL supports single-supply operation up to +30 V (or ±15 V dual supply), as confirmed by its absolute maximum rating of ±18 V or +36 V. For +30 V use, ensure input common-mode range (−11 V to +15 V) and output swing (±12.5 V into 2 kΩ) remain within specification limits.
What is the small-signal bandwidth of ADTL082ARMZ-REEL at gain = 10?
At noise gain = 10, the small-signal bandwidth of ADTL082ARMZ-REEL is approximately 500 kHz, derived from its 5 MHz gain-bandwidth product (GBP ÷ noise gain = 5 MHz ÷ 10). This enables stable closed-loop response for precision gain stages in sensor signal chains and active filter sections.
