Product details
Overview
TL082BIYDT from STMicroelectronics is a high-speed JFET-input dual operational amplifier with 16 V/µs typical slew rate, ±11 V input common-mode range (at ±15 V supply), and 1 mV maximum input offset voltage at 25 °C. It operates from ±3 V to ±18 V supply, supports automotive temperature range (−40 °C to +105 °C), and is qualified per AEC-Q100 Grade 1 for under-hood signal conditioning.
For engineers reviewing the TL082BIYDT datasheet, TL082BIYDT pinout, TL082BIYDT application, or TL082BIYDT equivalent, key selection criteria include input offset voltage drift (10 µV/°C), output short-circuit protection, JFET-input stage impedance (>10¹² Ω), and SO8 automotive-grade packaging with ECOPACK® compliance.
Technical Context
The TL082BIYDT integrates two matched JFET-input op-amps on a single monolithic die, using complementary bipolar transistors for output stages. Its internal frequency compensation ensures unity-gain stability without external components, and latch-up-free operation enables robust use in noisy automotive environments.
It delivers rail-to-rail-compatible output swing (±10 V into 2 kΩ) and maintains ≥25 V/mV large-signal voltage gain across −40 °C to +105 °C. Common-mode rejection (80 dB min) and supply voltage rejection (80 dB min) are specified over full temperature range, supporting precision DC-coupled amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3 V to ±18 V - supports dual-rail industrial and automotive power domains without level-shifting |
| Input Offset Voltage (25 °C) | 1 mV max - enables accurate low-level signal amplification in sensor front-ends |
| Slew Rate | 16 V/µs typ - allows faithful reproduction of 100 kHz sine waves at ±10 V amplitude |
| Input Bias Current | 20 pA typ - preserves signal integrity in high-impedance photodiode or piezo sensor interfaces |
| Common-Mode Rejection | 80 dB min (−40 °C to +105 °C) - rejects engine noise coupling in vehicle ECU analog inputs |
| Gain Bandwidth Product | 2.5 MHz min - supports stable closed-loop gain ≥10 up to 250 kHz |
| Output Short-Circuit Duration | Infinite - permits continuous safe operation during transient load faults |
Pinout & Package
TL082BIYDT is supplied in an SO8 (Small Outline 8-pin) package compliant with JEDEC MS-012, with ECOPACK® environmental certification and automotive-grade screening (AEC-Q100 Grade 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - drives feedback networks or downstream ADC drivers |
| 2 | Inverting Input A | High-impedance node for precision inverting configurations |
| 3 | Non-inverting Input A | Accepts low-current sensor signals without loading source |
| 4 | VCC− | Negative supply rail - must be decoupled within 1 cm of pin |
| 5 | Non-inverting Input B | Independent input for second channel - no crosstalk above 120 dB |
| 6 | Inverting Input B | Configurable for differential or single-ended B-channel use |
| 7 | Output B | Second independent output - supports dual-path signal processing |
| 8 | VCC+ | Positive supply rail - shared bias for both amplifiers |
Key Features
| Feature | Design Value |
|---|---|
| High Input Impedance | 10¹² Ω - minimizes loading on high-Z sources like crystal oscillators or capacitive sensors |
| Wide Common-Mode Range | ±11 V (at ±15 V supply) - accepts inputs near supply rails without phase reversal |

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 |
|---|---|---|---|
| TL082CDT | Commercial grade (0 °C to +70 °C), same SO8 package, 3 mV max Vio at 25 °C | Lacks AEC-Q100 qualification; unsuitable for under-hood deployment | Select only for non-automotive prototypes or cost-sensitive consumer boards |
| OPA2134UA | FET-input dual op-amp with lower Vio (0.5 mV max), higher GBP (8 MHz), but ±15 V max supply | Higher precision and bandwidth, but not AEC-Q100 qualified and incompatible with 18 V systems | Prefer where 12-bit+ ADC interface demands lower noise and distortion, not automotive reliability |
Compared with TL082CDT and OPA2134UA, TL082BIYDT uniquely combines AEC-Q100 Grade 1 qualification, ±18 V operation, and 1 mV Vio in SO8 - making it the only choice for production automotive analog signal chains requiring extended temperature resilience and fault tolerance.

FAQ
What is the maximum operating junction temperature for TL082BIYDT?
The TL082BIYDT has a maximum junction temperature of +150 °C, verified per AEC-Q100 stress testing. With SO8 package RthJA = 125 °C/W and 2.5 mA typical supply current per amplifier, sustained operation at +105 °C ambient requires ≤200 mW total dissipation - achievable with proper PCB copper area and airflow.
Does TL082BIYDT support single-supply operation?
Yes - TL082BIYDT operates with single supplies from 6 V to 36 V (e.g., 12 V or 24 V automotive rails), provided input common-mode and output swing remain within specified limits. The input common-mode range extends to within 3 V of VCC−, enabling direct interfacing with microcontroller ADC references.
How does the TL082BIYDT differ from the TL082IYDT?
TL082BIYDT specifies 1 mV max input offset voltage at 25 °C and 5 mV max over full temperature range, whereas TL082IYDT specifies 3 mV max at 25 °C and 13 mV max over temperature. Both share identical SO8 automotive packaging, AEC-Q100 Grade 1 qualification, and electrical ratings except offset parameters.
Can TL082BIYDT drive a 600 Ω audio load directly?
No - TL082BIYDT is not optimized for low-impedance audio loads. Its output short-circuit current is 10–60 mA, limiting usable load to ≥2 kΩ for linear operation. Driving 600 Ω risks clipping, thermal overload, and increased THD (>0.01%). Use dedicated audio line drivers (e.g., TPA6130A2) for such applications.
