Product details
Overview
TLE2082AIDRG4 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 –40°C to 85°C. It serves as a direct upgrade to TL082 and TL072 in precision analog front-ends for oscilloscopes and data acquisition systems.
For engineers reviewing the TLE2082AIDRG4 datasheet, TLE2082AIDRG4 pinout, TLE2082AIDRG4 application, or TLE2082AIDRG4 equivalent, key selection criteria include its JFET-input low-noise performance (7 nV/√Hz at 1 kHz, ±15 V), wide common-mode range (–10.9 V to +15 V), and dual-channel layout optimized for signal conditioning in AC drive power stages and electricity meters.
Technical Context
The TLE2082AIDRG4 implements a high-voltage JFET-input stage with complementary bipolar output, enabling rail-to-rail input operation and fast settling (0.25 μs to 10 mV on 2 V step). Its internal compensation ensures stable unity-gain operation with 56° phase margin and 300 kHz full-output-swing bandwidth under 25 pF load.
Designed for high-fidelity analog signal paths, it maintains low THD+N (0.0032%) at 1 kHz and supports dual independent amplifiers sharing only supply pins - no crosstalk degradation (120 dB attenuation) between channels at 2 kΩ load.
Key Specifications

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 | Limited to cost-sensitive, non-precision applications where speed and DC accuracy are secondary | Select when budget constraints outweigh need for 10.6 MHz BW or 4 mV VIO; verify stability with external compensation. |
| OPA2134PA | Lower noise (8 nV/√Hz), higher price, ±18 V max supply, no –40°C to +85°C rating | Better suited for audio-grade low-noise apps but lacks extended temperature qualification for industrial use | Prefer for audio or lab equipment where extended temp range is unnecessary; avoid in automotive or grid-edge deployments. |
Compared with TL082CDR and OPA2134PA, the TLE2082AIDRG4 delivers superior bandwidth and guaranteed industrial temperature operation while maintaining JFET-input benefits - making it optimal for high-reliability, wide-supply analog signal chains where both speed and DC precision matter.

FAQ
What is the maximum supply voltage for the TLE2082AIDRG4?
The TLE2082AIDRG4 supports a maximum supply voltage of ±19 V across its VCC+ and VCC– pins. This wide rail capability enables operation in legacy ±15 V industrial systems and high-dynamic-range signal conditioning circuits without external level-shifting. Absolute maximum ratings specify 38 V total supply differential, but recommended operating conditions limit continuous use to ±19 V to ensure long-term reliability and specified performance.
Does the TLE2082AIDRG4 require external compensation?
No, the TLE2082AIDRG4 is internally compensated for unity-gain stability, with a measured phase margin of 56° at unity gain under standard test conditions (CL = 25 pF, RL = 2 kΩ). It achieves stable operation with closed-loop gains ≥ 1 without external components, simplifying PCB layout and reducing bill-of-materials cost compared to decompensated alternatives like the TL082.
What is the input offset voltage specification for the TLE2082AIDRG4 over temperature?
The TLE2082AIDRG4 has a maximum input offset voltage of 4 mV over the full operating temperature range of –40°C to +85°C. At 25°C, the typical value is 0.65 mV, with a temperature coefficient of 2.3 μV/°C. This A-grade specification ensures predictable DC error in precision applications such as electricity metering and sensor signal conditioning without requiring factory trimming or system-level calibration.
How does the TLE2082AIDRG4 compare to the standard TLE2082IDR?
The TLE2082AIDRG4 is the A-grade version of the TLE2082, offering tighter input offset voltage (4 mV max vs. 7 mV max for TLE2082IDR) and improved temperature coefficient (2.3 μV/°C vs. 3.2 μV/°C). Both share identical pinout, bandwidth, slew rate, and package. The "A" designation indicates enhanced DC precision, making TLE2082AIDRG4 preferable for applications where offset drift and initial accuracy directly impact measurement integrity.
Is the TLE2082AIDRG4 RoHS compliant and lead-free?
Yes, the TLE2082AIDRG4 is RoHS compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. Its SOIC-8 package uses matte tin lead finish and conforms to IPC/JEDEC J-STD-020D reflow profiles. Full compliance documentation, including substance declarations and test reports, is available through Texas Instruments' official product folder and Aetrix Electronics' material compliance portal.
