Product details
Overview
TLE2082AID from Texas Instruments is a dual high-speed JFET-input operational amplifier with 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and ±19 V supply capability. It delivers low input offset voltage (max 4 mV at 25°C), low noise (7 nV/√Hz at 1 kHz, ±15 V), and operates across –40°C to +85°C. It serves as a direct upgrade to TL072/TL082 in precision AC signal conditioning, data acquisition front-ends, and oscilloscope vertical amplifiers.
For engineers reviewing the TLE2082AID datasheet, TLE2082AID pinout, TLE2082AID application, or TLE2082AID equivalent, key selection criteria include its dual-channel JFET architecture, wide supply range, high slew rate for fast transient response, and guaranteed performance over industrial temperature range - critical for high-fidelity analog signal paths in test equipment and energy metering systems.
Technical Context
The TLE2082AID uses matched JFET input pairs to achieve high input impedance (>100 MΩ common-mode, >6 TΩ differential), low input bias current (≤175 nA), and low voltage noise. Its internal compensation ensures stable unity-gain operation with 56°–57° phase margin and 300 kHz full-swing bandwidth under 25 pF load.
It supports rail-to-rail output swing within 1.5 V of rails at ±20 mA load and maintains CMRR ≥85 dB and PSRR ≥82 dB across its operating range. The device is specified for both ±5 V and ±15 V supplies, with common-mode input range extending to within 1.9 V of negative rail at ±5 V and within 11.9 V at ±15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10.6 MHz unity-gain - enables accurate amplification of signals up to ~1 MHz in closed-loop gain ≥10 configurations |
| Slew Rate | 32 V/μs - supports clean reproduction of 10 VPP signals at ≤3.2 MHz without slewing distortion |
| Supply Range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in high-voltage sensor interfaces and power stage monitoring |
| Input Offset Voltage | Max 4 mV at 25°C (TLE2082A grade) - reduces DC error in precision integrators and active filters |
| Input Noise | 7 nV/√Hz at 1 kHz (±15 V) - preserves SNR in low-level signal amplification stages |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded instrumentation and energy infrastructure |

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 |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher input offset (10 mV max), no industrial temp grade | Limited to commercial-temp, lower-precision applications like audio preamps and basic signal conditioning | Select only when cost sensitivity outweighs performance requirements and ambient temperature stays within 0°C–70°C |
| OPA2134PA | Higher precision (500 μV VIO max), lower noise (8 nV/√Hz), but lower slew rate (20 V/μs) and narrower supply (±18 V max) | Better for ultra-low-distortion audio; less suitable for fast transient capture in power electronics | Prefer for high-fidelity audio or low-frequency precision instrumentation where speed is secondary to DC accuracy |
Compared with TL072CDR and OPA2134PA, the TLE2082AID uniquely balances high speed (10.6 MHz, 32 V/μs), industrial temperature operation, and robust ±19 V supply tolerance - making it optimal for demanding real-time signal acquisition in energy, test, and industrial automation systems.

FAQ
What is the maximum supply voltage for the TLE2082AID?
The TLE2082AID supports a total supply voltage range of ±2.25 V to ±19 V, meaning the absolute maximum difference between VCC+ and VCC– is 38 V. Operation beyond ±19 V violates Absolute Maximum Ratings and risks permanent damage. At ±15 V, it delivers full-rated performance including 13.5 V output swing at 2 mA load.
Does the TLE2082AID have rail-to-rail output capability?
No, the TLE2082AID does not feature rail-to-rail output. At ±15 V supply and 20 mA load, its output swings from –11.5 V to +11.5 V - a 23 V peak-to-peak range centered on ground. Minimum headroom is 1.5 V from each rail under heavy load, increasing to ~0.015 V at light loads (200 μA).
Is the TLE2082AID pin-compatible with the TL072?
Yes, the TLE2082AID is fully pin-compatible with the TL072 in the same SOIC-8 (D) or PDIP-8 (P) packages. Both share identical pin assignments: 1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+. This allows drop-in replacement without PCB changes when upgrading bandwidth and precision.
What is the input bias current specification for the TLE2082AID?
The TLE2082AID exhibits a maximum input bias current of 175 nA at 25°C, with typical values around 15–20 nA. This JFET-input characteristic remains stable across temperature, enabling high-impedance sensor interfacing (e.g., pH electrodes, photodiode transimpedance amps) without significant DC error from bias current flow.
Can the TLE2082AID drive a 600 Ω load effectively?
Yes, the TLE2082AID is characterized into 600 Ω loads, delivering ≥80 dB large-signal voltage gain and maintaining 56° phase margin. Its open-loop output impedance is low enough to sustain stable operation, though output swing is reduced to ±3.5 V at ±2 mA - sufficient for line-driver and video buffer applications requiring moderate drive strength.
