Product details
Overview
ADTL082ARMZ 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 max input bias current. It serves as a precision signal conditioning and buffering IC in industrial sensor interfaces and data acquisition front-ends.
For engineers reviewing the ADTL082ARMZ datasheet, ADTL082ARMZ pinout, ADTL082ARMZ application, or ADTL082ARMZ equivalent, this page delivers verified specifications, thermal performance data, real-world use cases, and validated alternative options for high-reliability analog design.
Technical Context
The ADTL082ARMZ implements a dual-channel JFET-input architecture with unity-gain stability, enabling accurate DC-coupled amplification without external compensation. Its input stage delivers ultra-low bias current (≤10 pA) and low offset voltage (≤5.5 mV), critical for high-impedance source interfacing.
It operates from ±15 V supplies, achieves 80 dB minimum CMRR, and maintains 0.001% THD at 1 kHz - making it suitable for active filtering and precision instrumentation where signal integrity and linearity are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5 MHz - supports stable closed-loop operation up to 5× gain at 1 MHz or unity gain at 5 MHz. |
| Slew Rate | 20 V/μs - enables faithful reproduction of fast-rising signals up to ~3.2 MHz full-power bandwidth (±10 V swing). |
| Input Bias Current | 10 pA maximum - preserves signal fidelity when driving from high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Offset Voltage | 5.5 mV maximum (A grade) - ensures ≤5.5 mV DC error at room temperature, reducing calibration burden in precision measurement paths. |
| Supply Current per Amplifier | 1.2 mA typical - allows dual-channel operation at <2.5 mA total, supporting low-power industrial modules. |
| Common-Mode Rejection Ratio | 80 dB minimum - rejects noise common to both inputs, critical in noisy industrial environments with ground offsets. |
| Voltage Noise Density | 16 nV/√Hz at 1 kHz - contributes minimal broadband noise in audio and sensor signal chains requiring SNR >90 dB. |
Pinout & Package
ADTL082ARMZ is housed in an 8-lead MSOP (RM-8) package, 3.0 mm × 3.0 mm × 0.85 mm, with exposed pad for thermal enhancement (θJA = 210°C/W, θJC = 45°C/W). Pin 1 is marked by a dot; device is RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Output of Amplifier A - drives load directly; capable of ±13 V swing into 10 kΩ at ±15 V supply. |
| 2 | –IN A | Inverting input of Amplifier A - high-impedance JFET node; requires matched trace impedance for optimal CMRR. |
| 3 | +IN A | Non-inverting input of Amplifier A - referenced to system ground or bias network; sensitive to EMI if unshielded. |
| 4 | –V | Negative supply rail - must be established before input signals to prevent phase reversal or latch-up. |
| 5 | +IN B | Non-inverting input of Amplifier B - electrically isolated from Channel A; enables independent dual-path signal processing. |
| 6 | –IN B | Inverting input of Amplifier B - shares same low-bias-current characteristics as Pin 2; usable for differential input stages. |
| 7 | OUT B | Output of Amplifier B - fully independent output stage; supports simultaneous dual-channel buffering or gain stages. |
| 8 | +V | Positive supply rail - decoupling capacitor (0.1 μF ceramic) required within 5 mm for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| TL082-compatible pinout and function | Direct drop-in replacement for legacy TL082 designs without PCB or schematic changes. |
| Low input bias current (≤10 pA) | Enables use with megohm-range feedback networks and high-Z sensors without significant DC error drift. |
| Extended temperature range (−40°C to +125°C) | Qualified for under-hood automotive, motor control, and industrial PLC applications without derating. |
| 16 nV/√Hz input voltage noise | Supports 16-bit+ resolution in data acquisition systems where noise floor limits effective bits. |
| 0.001% THD at 1 kHz | Meets audio-grade and precision waveform generation requirements without post-amplifier correction. |

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 input bias current (200 pA typ), wider offset voltage (15 mV max), commercial temp range only (0°C to 70°C). | Limited to non-critical consumer or lab equipment; not qualified for extended temperature or low-drift designs. | Select only when cost is primary constraint and thermal/stability margins are generous. |
| OPA2134UA | Lower noise (8 nV/√Hz), lower THD (0.00008%), but higher supply current (4 mA/ch) and no MSOP option (SOIC-8 only). | Better for audio or ultra-low-distortion applications; less suitable for space-constrained industrial PCBs. | Choose when SNR >110 dB is mandatory and board area allows SOIC-8 footprint. |
Compared with TL082CDR, ADTL082ARMZ offers 20× lower input bias current and extended temperature qualification; compared with OPA2134UA, it trades 8 dB noise advantage for 50% lower quiescent power and compact MSOP packaging - optimizing for industrial reliability and density.

FAQ
What is the operating temperature range for ADTL082ARMZ?
The ADTL082ARMZ is rated for −40°C to +125°C, matching the extended industrial temperature grade (A grade). This specification is confirmed in the Ordering Guide and Absolute Maximum Ratings table of the Rev. B datasheet, and applies to all units shipped with "ARMZ" suffix and "A18" branding.
Is ADTL082ARMZ pin-compatible with standard TL082 devices?
Yes, ADTL082ARMZ uses the same dual-op-amp pinout as TL082 in 8-lead packages - Pins 1–4 and 5–8 map identically to OUT A, –IN A, +IN A, –V, +IN B, –IN B, OUT B, and +V. However, note that ADTL082ARMZ is in MSOP (RM-8), while most TL082 variants use SOIC_N (R-8); physical compatibility requires footprint adaptation.
What is the maximum output voltage swing for ADTL082ARMZ at ±15 V supply?
At ±15 V supply and 25°C, ADTL082ARMZ delivers ±13.5 V maximum peak output voltage into 10 kΩ (Table 1, "Maximum Output Voltage Swing"). Under load (2 kΩ), swing reduces to ±13.3 V. Performance degrades slightly at temperature extremes, down to ±13 V at −40°C to +125°C.
Does ADTL082ARMZ require external compensation for unity-gain stability?
No, ADTL082ARMZ is internally compensated and unity-gain stable, as explicitly stated in both the Features list and General Description. No external capacitors or feedback adjustments are needed for stable operation at gain ≥1, simplifying layout and reducing BOM count.
What package type and dimensions does ADTL082ARMZ use?
ADTL082ARMZ uses an 8-lead MSOP (RM-8) package measuring 3.0 mm × 3.0 mm × 0.85 mm, with 0.65 mm pitch and exposed thermal pad. Dimensions and mechanical drawings are provided in Figure 23 and Page 8 of the Rev. B datasheet, compliant to JEDEC MO-187-AA.
