Product details
Overview
TLE2082ACDG4 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, and ±19 V supply capability. It provides low input offset voltage (max 4 mV at 25°C), low noise (7 nV/√Hz at 1 kHz, ±15 V), and direct upgrade path for TL082, TL072, and TL052 in precision AC signal conditioning circuits.
For engineers reviewing the TLE2082ACDG4 datasheet, TLE2082ACDG4 pinout, TLE2082ACDG4 application, or TLE2082ACDG4 equivalent, this device is selected for high-fidelity analog front-ends where wide dynamic range, fast settling (<0.4 μs to 1 mV), and rail-to-rail output swing under load are required - especially in oscilloscope vertical amplifiers, energy meter sensor interfaces, and flight control signal conditioning.
Technical Context
The TLE2082ACDG4 uses a JFET-input stage with matched die geometry to achieve low input bias current (≤175 nA) and low input offset drift (2.3 μV/°C typical). Its internal compensation ensures stable unity-gain operation with ≥56° phase margin into 2 kΩ//25 pF loads.
It operates across ±2.25 V to ±19 V supplies and supports full common-mode input range down to within 1.9 V of negative rail (±15 V supply). Output delivers ±14.5 V swing at 20 mA load, enabling direct interfacing with ADC drivers and active filters without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 with ≤1% gain error up to 1 MHz in non-inverting configurations |
| Slew rate | 32 V/μs - supports 10 VPP signals up to ~500 kHz without slewing distortion |
| Input offset voltage | Max 4 mV at 25°C - limits DC error to <0.1% in 4 V full-scale sensor amplification |
| Supply voltage range | ±2.25 V to ±19 V - accommodates industrial ±15 V rails and extended-range data acquisition systems |
| Output voltage swing | ±14.5 V at 20 mA load - delivers full-scale drive into 750 Ω loads typical of coaxial cable termination |
| Input voltage noise | 7 nV/√Hz at 1 kHz (±15 V) - preserves SNR >90 dB in 10 kHz bandwidth measurement channels |
| Crosstalk attenuation | 120 dB - prevents inter-channel coupling in dual-channel simultaneous sampling systems |
Pinout & Package
SOIC-8 (D) package, 4.9 mm × 6.0 mm body, 1.27 mm pitch, gull-wing leads. RoHS-compliant, Pb-free finish.

| 1IN+ | Non-inverting Input, Channel 1 | Differential input node; matched to 1IN– for low VIO and drift |
| VCC– | Power Supply Negative | Negative rail connection; must be decoupled locally with ≥0.1 μF ceramic |
| 2IN+ | Non-inverting Input, Channel 2 | Independent second amplifier input; electrically isolated from Channel 1 |
| 2IN– | Inverting Input, Channel 2 | Second differential pair input; shares no internal nodes with Channel 1 |
| 2OUT | Output Channel 2 | Second independent output; identical AC/DC specs to 1OUT |
| VCC+ | Power Supply Positive | Positive rail connection; requires local 0.1 μF + 10 μF decoupling |
Key Features

| Low 1/f noise | 2.77 μVPP (0.1–10 Hz) enables stable DC-coupled amplification in precision weigh scales and strain gauge bridges |
| High CMRR & PSRR | 85 dB CMRR and 99 dB PSRR minimize error from ground bounce and supply ripple in noisy industrial environments |
| Fast settling time | 0.4 μs to 1 mV for 10 V step ensures accurate digitization in 2.5 MSPS data acquisition systems |

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 |
|---|---|---|---|
| TL082CDR | Lower bandwidth (4 MHz), higher VIO (15 mV max), no A-grade option; same SOIC-8 pinout | Acceptable for general-purpose AC coupling but insufficient for <1 μs settling or low-noise metrology | Select when cost sensitivity outweighs precision and speed requirements |
| OPA2134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but only ±18 V supply; SOIC-8, not pin-compatible | Better for audio and low-drift instrumentation, but requires layout change and lacks ±19 V robustness | Select when ultra-low distortion (<0.00008% THD+N) and long-term stability are critical |
Compared with TL082CDR, TLE2082ACDG4 delivers 2.6× higher bandwidth and 3.7× lower offset for demanding signal chains; versus OPA2134PA, it trades minor noise penalty for superior supply ruggedness and direct TL082 compatibility - making it optimal for industrial test equipment upgrades.

FAQ
What is the maximum supply voltage rating for TLE2082ACDG4?
The TLE2082ACDG4 supports a total supply voltage (VCC+ to VCC–) of up to 38 V, enabling operation from ±2.25 V to ±19 V. This allows use in industrial systems with extended rails and transient-tolerant designs where standard ±15 V op-amps would saturate or fail.
Does TLE2082ACDG4 support rail-to-rail input or output?
The TLE2082ACDG4 does not provide rail-to-rail input - its common-mode input range extends to within 1.9 V of the negative rail (e.g., –13.1 V at ±15 V supply). However, its output swings to within 0.5 V of each rail at light loads and maintains ±14.5 V at 20 mA, offering near-rail performance for most precision applications.
Is TLE2082ACDG4 pin-compatible with TL082?
Yes, TLE2082ACDG4 is fully pin-compatible with TL082 in SOIC-8 (D) package. Pin functions match exactly: 1OUT/1IN–/1IN+/VCC–/2IN+/2IN–/2OUT/VCC+. No PCB modification is required for drop-in replacement, preserving layout integrity during performance upgrades.
What is the typical input bias current of TLE2082ACDG4?
The typical input bias current of TLE2082ACDG4 is 15 nA at 25°C, with a maximum of 175 nA across the full temperature range (0°C to 70°C). This JFET-input characteristic enables high-impedance sensor interfacing - such as piezoelectric transducers or pH electrodes - without significant loading error.
Can TLE2082ACDG4 drive capacitive loads directly?
TLE2082ACDG4 is internally compensated for unity-gain stability with resistive loads but may oscillate with >50 pF capacitive loads. For direct capacitive driving (e.g., coaxial cables or ADC input capacitance), a series resistor (≥100 Ω) between output and load is recommended to maintain ≥56° phase margin and prevent peaking.
