Product details
Overview
TL082QDRQ1 from Texas Instruments is a dual JFET-input operational amplifier qualified for automotive applications, delivering 21 V/μs slew rate, ±14.95 V output swing (RL = 10 kΩ), 4.5 MHz unity-gain bandwidth, and 0.003% typical THD at 1 kHz - used in TFT-LCD VCOM drivers and A/D converter buffering.
For engineers reviewing the TL082QDRQ1 datasheet, TL082QDRQ1 pinout, TL082QDRQ1 application, or TL082QDRQ1 equivalent, this page provides verified electrical specs, SOIC-8 pin mapping, automotive-grade thermal validation (–40°C to 125°C), and real-world design context for high-side sensing and headphone amplification.
Technical Context
The TL082QDRQ1 integrates matched high-voltage JFET and bipolar transistors on a monolithic die, enabling latchup-free operation and rail-to-rail common-mode input range extending to VCC+. Its FET-input stage delivers 10¹² Ω input resistance and sub-100 pA input bias current at 25°C.
It features a new-die architecture with slew boost, reducing total harmonic distortion to 0.00021% (VS = 40 V, G = 1, f = 1 kHz) and improving supply current to 0.56 mA per amplifier - while maintaining compatibility with legacy TL082 designs in SOIC-8 packaging.

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 | Commercial-grade (–40°C to +85°C); higher input offset (±3 mV typ) and lower slew rate (13 V/μs) | Not qualified for automotive use; unsuitable for under-hood or safety-critical modules | Select only for cost-sensitive non-automotive industrial or consumer designs where AEC-Q100 is not required |
| OPA2134UA | Lower noise (8 nV/√Hz), lower THD (0.00008%), but higher quiescent current (4 mA per amp) and no AEC-Q100 certification | Targeted at premium audio; lacks automotive temperature validation and fails ESD robustness (HBM 1.5 kV vs OPA2134's 2 kV) | Prefer for studio-grade audio; avoid in automotive due to unqualified temp range and insufficient ESD margin |
Compared with TL082CDR and OPA2134UA, TL082QDRQ1 uniquely balances AEC-Q100 compliance, 21 V/μs slew rate, and 0.003% THD - making it the only drop-in solution for automotive VCOM drivers and dual-channel sensor buffers requiring production-grade reliability.

FAQ
What is the maximum operating temperature for TL082QDRQ1?
The TL082QDRQ1 is rated for continuous operation from –40°C to +125°C, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all electrical parameters in the datasheet, including input offset voltage drift (±0.3 μV/°C) and output swing retention at temperature extremes.
Does TL082QDRQ1 support single-supply operation?
Yes, TL082QDRQ1 supports single-supply operation because its common-mode input voltage range extends to VCC+. When powered with +15 V and ground, inputs can accept signals from 0 V to +15 V - enabling direct interfacing with microcontroller ADC references and digital logic without level-shifting circuitry.
What is the input bias current of TL082QDRQ1 at 125°C?
At 125°C, the TL082QDRQ1 exhibits input bias current ≤50 nA (max), per Section 5.3 of the datasheet. This value reflects the temperature sensitivity of JFET junction leakage and remains well below 100 nA - preserving accuracy in high-impedance sensor front-ends even at maximum operating temperature.
Is TL082QDRQ1 pin-compatible with legacy TL082 variants?
Yes, TL082QDRQ1 uses the standard SOIC-8 (D) package with identical pinout to TL082CDR, TL082IDR, and TL082QDR. The device maintains full electrical and mechanical compatibility, allowing drop-in replacement in existing designs - though users should verify layout thermal relief for the higher 125°C ambient rating.
What is the ESD rating of TL082QDRQ1?
TL082QDRQ1 has a Human-Body Model (HBM) ESD rating of 1.5 kV and Charged-Device Model (CDM) rating of 1.5 kV, per JEDEC JESD22-A114 and JESD22-C101. These ratings are validated for production units and apply across the full –40°C to +125°C operating range.
