Product details
Overview
TLE2082ACD from Texas Instruments is a dual high-speed JFET-input operational amplifier in SOIC-8 package, delivering 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, ±19 V supply capability, and 4 mV max input offset voltage at 25°C. It serves as a direct upgrade to TL072/TL082 in precision AC-coupled signal conditioning stages for oscilloscopes and data acquisition systems.
For engineers reviewing the TLE2082ACD datasheet, TLE2082ACD pinout, TLE2082ACD application, or TLE2082ACD equivalent, this page provides verified electrical characteristics, dual-channel pin mapping, thermal derating data, crosstalk attenuation (120 dB), and validated alternatives for high-voltage, low-noise analog front-end designs.
Technical Context
The TLE2082ACD uses JFET-input differential pairs with matched high-voltage lateral PNP transistors in the gain stage, enabling rail-to-rail common-mode input range (±10.9 V at ±15 V supplies) and low input bias current (15–175 nA). Its internal compensation ensures stable unity-gain operation with 56° phase margin into 2 kΩ//25 pF loads.
It operates across 0°C to 70°C ambient temperature with ±2.25 V to ±19 V dual-supply support, delivering 2.4 mA per amplifier quiescent current and 65 mA short-circuit output capability. The device exhibits 28 nV/√Hz input voltage noise at 1 kHz and 60 fA/√Hz input current noise-critical for high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - supports stable closed-loop amplification up to audio and low-speed RF frequencies without external compensation |
| Slew rate | 32 V/μs - enables faithful reproduction of fast 2-V step signals within 0.25 μs to 10 mV error band |
| Input offset voltage (max) | 4 mV at 25°C - ensures ≤0.08% gain error in 50× inverting amplifier configurations |
| Supply voltage range | ±2.25 V to ±19 V - accommodates industrial ±15 V rails and extended-range signal chains without level-shifting |
| Crosstalk attenuation | 120 dB - prevents inter-channel coupling in dual-signal-path applications like stereo audio or differential ADC drivers |
| Common-mode input range | –10.9 V to +15 V at ±15 V supplies - accepts inputs within 1.1 V of either rail for single-supply-compatible bipolar operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CD | Lower bandwidth (3 MHz), higher VIO (10 mV max), no crosstalk spec, ±15 V max supply | Limited to lower-frequency (<500 kHz), less demanding precision applications | Select when cost sensitivity outweighs speed/precision needs and ±15 V rails suffice |
| OPA2134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but 8 MHz bandwidth and ±18 V max supply | Better for ultra-low-noise audio and medical instrumentation; lower slew rate (20 V/μs) | Choose for sub-10 μV offset and <10 nV/√Hz noise requirements where 10.6 MHz bandwidth is not critical |
Compared with TL072CD and OPA2134PA, the TLE2082ACD uniquely balances 10.6 MHz bandwidth, ±19 V operation, and 4 mV VIO in an industry-standard SOIC-8, making it optimal for industrial test equipment requiring extended voltage range and moderate precision.

FAQ
What is the maximum supply voltage rating for the TLE2082ACD?
The TLE2082ACD supports dual-supply operation from ±2.25 V to ±19 V. Absolute maximum ratings specify ±38 V total supply differential (VCC+ to VCC–), but recommended continuous operation is limited to ±19 V to ensure long-term reliability and specified performance across temperature. Exceeding ±19 V may degrade input stage integrity or accelerate parametric drift.
Does the TLE2082ACD require external compensation for unity-gain stability?
No, the TLE2082ACD is internally compensated for unity-gain stability with a guaranteed 56° phase margin into 2 kΩ resistive loads and up to 25 pF capacitive loads. External compensation is unnecessary for standard inverting or non-inverting configurations; however, driving >25 pF directly requires series resistor isolation per TI Application Report SLOA020.
How does the input offset voltage of the TLE2082ACD compare to the TL082?
The TLE2082ACD has a maximum input offset voltage of 4 mV at 25°C, compared to 15 mV for the TL082. This 3.75× improvement reduces gain-stage DC error in precision applications-for example, a 100× gain amplifier using TLE2082ACD contributes ≤0.4 V offset versus ≤1.5 V with TL082 under identical conditions.
Can the TLE2082ACD replace the TL072 in existing designs without layout changes?
Yes-the TLE2082ACD uses the same SOIC-8 pinout and functional assignment as the TL072, including identical 1OUT/1IN–/1IN+/VCC–/2IN+/2IN–/2OUT/VCC+ mapping. It is a direct drop-in upgrade with improved bandwidth (10.6 MHz vs. 3 MHz), lower noise, and wider supply range, requiring only verification of supply voltage and thermal margins.
What is the crosstalk specification for the TLE2082ACD, and why does it matter?
The TLE2082ACD specifies 120 dB crosstalk attenuation between its two amplifier channels. This means a 1 V signal on Channel 1 induces less than 1 μV of coupled signal on Channel 2-critical in dual-path applications like differential input stages or stereo instrumentation where channel independence directly impacts measurement accuracy and signal fidelity.
