Product details
Overview
TL082IDRQ1 from Texas Instruments is a dual JFET-input operational amplifier qualified for automotive applications, delivering 21 V/μs slew rate, ±14.95 V maximum output swing (RL = 10 kΩ), and 0.003% typical total harmonic distortion at 1 kHz. It operates across –40°C to 85°C and serves as a precision buffer in A/D converters and high-side sensing circuits.
For engineers reviewing the TL082IDRQ1 datasheet, TL082IDRQ1 pinout, TL082IDRQ1 application, or TL082IDRQ1 equivalent, key selection criteria include its FET-input stage enabling low input bias current (±10 pA typ), wide common-mode range extending to VCC+, and automotive-grade temperature qualification with SOIC-8 packaging.
Technical Context
The TL082IDRQ1 integrates matched high-voltage JFET and bipolar transistors on a monolithic die, supporting rail-to-rail common-mode input voltage (–12 V to +15 V at ±15 V supplies) and latchup-free operation. Its architecture enables high open-loop gain (130 dB typ) and 4.5 MHz unity-gain bandwidth while maintaining low noise (10.8 nV/√Hz at 1 kHz).
Designed for signal conditioning in safety-critical automotive subsystems, it features robust ESD protection (1.5 kV HBM), supply-voltage rejection ratio of 130 dB, and crosstalk attenuation of 120 dB between channels - all verified over its full operating temperature range.

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 |
|---|---|---|---|
| TL072CDR | Wider temp range (0°C to 70°C), higher input offset (±3 mV typ), no automotive qualification | Not suitable for under-hood or safety-critical modules requiring AEC-Q100 compliance | Select only for cost-sensitive non-automotive industrial designs where extended temperature is not required |
| OPA2134UA | Lower noise (8 nV/√Hz), higher slew rate (20 V/μs), but higher quiescent current (4 mA per amp) | Better audio performance but incompatible with low-power ECU subsystems constrained by <1 mA per channel | Prefer when THD <0.001% and wider bandwidth are mandatory, accepting higher supply current |
Compared with TL082IDRQ1, TL072CDR lacks automotive qualification and exhibits higher offset drift, while OPA2134UA delivers superior audio specs at the cost of doubled supply current - making TL082IDRQ1 optimal for balanced performance in automotive signal conditioning.

FAQ
What is the operating temperature range for TL082IDRQ1?
The TL082IDRQ1 is specified for operation from –40°C to +85°C, meeting AEC-Q100 Grade 3 requirements for automotive under-dash applications. This range is confirmed in Section 5.1 of the SLOS548A datasheet and validated across all electrical parameters including input offset voltage, slew rate, and output swing.
Does TL082IDRQ1 support rail-to-rail input operation?
Yes, TL082IDRQ1 supports common-mode input voltage up to VCC+, as stated in the "Features" section and Table 5-3 (VICR = –12 V to +15 V at ±15 V supply). This allows use in single-supply configurations where the non-inverting input can accept signals near the positive rail without phase reversal.
What is the maximum output voltage swing for TL082IDRQ1 at ±15 V supply?
At ±15 V supply and RL = 10 kΩ, TL082IDRQ1 delivers ±14.95 V typical peak output voltage swing (Table 5-3, VOM parameter). This 100 mV headroom from rails ensures compatibility with downstream ADCs requiring ≥14 V full-scale input range.
Is TL082IDRQ1 pin-compatible with legacy TL082 variants?
Yes, TL082IDRQ1 uses the standard SOIC-8 (D) package with identical pinout to industry-standard TL082 devices, including TL082CP, TL082CDR, and TL082ACDR. Pin functions are fully documented in Table 4-1 of the SLOS548A datasheet and verified across TI's production release notes.
What packaging and reel specifications apply to TL082IDRQ1?
TL082IDRQ1 ships in SOIC-8 (D) package on large tape-and-reel: 2500 units per reel, RoHS-compliant NiPdAu lead finish, and MSL Level-1 (unlimited floor life at ≤30°C/60% RH). These details are confirmed in TI's Packaging Information addendum dated 6-Feb-2026.
