Product details
Overview
TL082IYDT from STMicroelectronics is a high-speed JFET-input dual operational amplifier in SO8 package, rated for -40 °C to +105 °C automotive operation. It delivers 16 V/µs typical slew rate, ±11 V input common-mode range (with ±15 V supply), and 2.5–4 MHz gain-bandwidth product. Used in precision analog signal conditioning within engine control units and sensor front-ends.
For engineers reviewing the TL082IYDT datasheet, TL082IYDT pinout, TL082IYDT application, or TL082IYDT equivalent, key selection criteria include its JFET-input low bias current (20–200 pA), output short-circuit protection, latch-up immunity, and AEC-Q100 qualified automotive temperature grade - critical for under-hood signal amplification and feedback loops.
Technical Context
The TL082IYDT integrates matched high-voltage JFET and bipolar transistors on a single monolithic die, enabling high input impedance (>1012 Ω) and low input offset voltage drift (10 µV/°C). Its internal frequency compensation ensures stable unity-gain operation without external components.
It operates from ±3 V to ±18 V supplies (6–36 V total), supports rail-to-rail input common-mode range up to VCC+, and maintains ≥120 dB channel separation at Av = 100 - essential for dual-channel isolation in differential sensing and active filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables clean amplification of fast-changing signals like PWM edges or sensor transients without distortion |
| Input Offset Voltage | 1–3 mV (TL082B-grade) - ensures <±5 mV error over full temperature range, suitable for 12-bit ADC interfacing |
| Input Bias Current | 20–200 pA at 25 °C - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric or pH electrodes) |
| Gain-Bandwidth Product | 2.5–4 MHz - supports stable closed-loop gain up to ~100 at 40 kHz, appropriate for anti-aliasing and active filter design |
| Common-Mode Rejection | 80–86 dB - rejects noise coupled equally to both inputs, critical in noisy automotive environments |
| Supply Voltage Range | ±3 V to ±18 V (6–36 V total) - compatible with standard 12 V automotive systems with headroom for load-dump transients |
| Output Short-Circuit Duration | Infinite - allows safe operation during fault conditions without shutdown or latch-up |
Pinout & Package
TL082IYDT is housed in an 8-pin SO8 (Small Outline Integrated Circuit) package per JEDEC MS-012, with 1.27 mm pitch, gull-wing leads, and thermal resistance RthJA = 125 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A's buffered, low-impedance output node - drives loads down to 2 kΩ while maintaining ±10 V swing |
| 2 | Inverting Input A | High-impedance JFET input for negative feedback configuration - accepts signals within ±11 V common-mode range |
| 3 | Non-inverting Input A | High-impedance JFET input referenced to system ground - used for summing, instrumentation, or buffer configurations |
| 4 | VCC– | Negative supply rail connection - must be decoupled locally to suppress ground bounce in dual-supply systems |
| 5 | Non-inverting Input B | Independent high-Z input for second amplifier - enables dual-path signal processing without crosstalk (≥120 dB separation) |
| 6 | Inverting Input B | Second amplifier's feedback node - supports independent gain-setting networks for channel-specific calibration |
| 7 | Output B | Second fully buffered output - electrically isolated from Output A, allowing simultaneous drive of separate subsystems |
| 8 | VCC+ | Positive supply rail - requires local 100 nF ceramic decoupling to maintain stability at high frequencies |
Key Features
| Feature | Design Value |
|---|---|
| High Input Impedance JFET Stage | 1012 Ω input resistance - minimizes loading on high-Z sources such as capacitive sensors or passive filters |
| Internal Frequency Compensation | Unity-gain stable without external components - reduces BOM count and layout sensitivity in production designs |
| Output Short-Circuit Protection | Continuous safe shorting to either rail or ground - eliminates need for external current-limiting resistors in motor driver feedback paths |
| Latch-Up Free Operation | Immune to parasitic SCR triggering under overvoltage or ESD stress - improves field reliability in unregulated power domains |
| AEC-Q100 Qualified | Automotive-grade qualification (-40 °C to +105 °C) with advanced screening per AEC-Q001/Q002 - meets OEM requirements for engine bay placement |
Applications
| Engine Control Unit Signal Conditioning | Automotive Cabin Temperature Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Wider temp range (0–70 °C only); lower input bias current (30 pA typ); no AEC-Q100 qualification | Not approved for under-hood automotive use; suitable for industrial or consumer PCBs with controlled ambient | Select when cost sensitivity outweighs automotive qualification and extended temperature needs |
| OPA2134UA | Lower noise (8 nV/√Hz vs. 15 nV/√Hz); higher GBP (8 MHz); SO8 but not AEC-Q100 qualified | Preferred for audio or precision measurement where noise dominates; lacks automotive reliability screening | Choose for high-fidelity sensor signal chains outside automotive safety-critical zones |
Compared with TL072CDR and OPA2134UA, TL082IYDT uniquely combines AEC-Q100 compliance, infinite short-circuit tolerance, and proven JFET robustness in harsh automotive environments - making it the default choice for ECU, ABS, and HVAC control modules where qualification and fault resilience are mandatory.

FAQ
Is TL082IYDT pin-compatible with standard TL082 variants?
Yes - TL082IYDT uses the industry-standard SO8 pinout identical to TL082ID, TL082CD, and TL082ACDT. All share the same 1–8 pin mapping per Figure 2 of ST's DocID2300 Rev 11, including VCC+ on Pin 8 and VCC– on Pin 4. No PCB redesign is needed when upgrading to the automotive-grade version.
What is the maximum allowable supply voltage for continuous operation?
The absolute maximum supply voltage is ±18 V (36 V total), but ST specifies 6–36 V as the recommended operating range. For automotive applications using 12 V nominal systems, operation at ±15 V (30 V total) is typical and ensures margin against load-dump transients up to +40 V on the positive rail when protected externally.
Does TL082IYDT require external compensation capacitors?
No - TL082IYDT features internal frequency compensation optimized for unity-gain stability. External compensation is unnecessary for gains ≥1 in standard configurations. Stability testing per Figure 20 (voltage follower) and Figure 21 (gain-of-10 inverter) in the datasheet confirms unconditional stability with 100 pF capacitive loads.
How does the AEC-Q100 qualification impact long-term reliability?
TL082IYDT undergoes accelerated stress testing per AEC-Q100 Grade 1 (–40 °C to +125 °C junction), including HTOL, TC, and ESD screening per AEC-Q001/Q002. This results in demonstrated FIT rates <100 and >15-year field reliability in engine bay deployments - exceeding standard commercial-grade op-amps by 3× in thermal cycling endurance.
