Product details
Overview
TL082ID from STMicroelectronics is a high-speed JFET-input dual operational amplifier in SO8 package, featuring 16 V/µs typical slew rate, ±11 V input common-mode range, 2.5 MHz gain-bandwidth product, and ±15 V maximum input voltage. It operates from ±6 V to ±18 V supply, supports industrial temperature range (–40 °C to +105 °C), and is used in precision signal conditioning, active filtering, and sensor interface circuits.
For engineers reviewing the TL082ID datasheet, TL082ID pinout, TL082ID application, or TL082ID equivalent, key selection criteria include input bias current (20–200 pA), offset voltage drift (10 µV/°C), output short-circuit protection, and SO8 thermal resistance (125 °C/W), critical for stability in multi-stage analog designs.
Technical Context
The TL082ID integrates matched high-voltage JFET and bipolar transistors on a single monolithic die, enabling high input impedance (>10¹² Ω) and low input bias current. Its internal frequency compensation ensures unity-gain stability without external components.
It delivers rail-to-rail compatible output swing (±10 V into 2 kΩ), 80 dB minimum CMRR and PSRR at 25 °C, and maintains phase margin ≥45° across operating conditions-supporting reliable closed-loop performance in instrumentation-grade amplifiers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables faithful reproduction of fast-changing signals up to ~1 MHz at 10 Vpp |
| Gain-Bandwidth Product | 2.5 MHz - sets usable closed-loop bandwidth for gain ≥10 configurations |
| Input Offset Voltage | 3–10 mV (25 °C), ≤13 mV (–40 to +105 °C) - defines DC accuracy in precision summing/integrating stages |
| Input Bias Current | 20–200 pA (25 °C) - minimizes error in high-impedance sensor interfaces (e.g., photodiode transimpedance) |
| Common-Mode Range | ±11 V (with ±15 V supply) - allows operation with inputs near supply rails in single-supply derived systems |
| Output Short-Circuit Duration | Infinite - permits robust fault tolerance without latch-up or permanent damage |
| Supply Voltage Range | ±6 V to ±18 V - supports wide dynamic headroom for audio, test equipment, and industrial control front-ends |
Pinout & Package
TL082ID is supplied 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 of 125 °C/W (junction-to-ambient).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output; drives load directly; short-circuit protected |
| 2 | Inverting Input A | High-impedance JFET node; accepts feedback network for inverting configuration |
| 3 | Non-inverting Input A | High-impedance JFET node; referenced to ground or common-mode bias in non-inverting mode |
| 4 | VCC– | Negative supply rail; must be decoupled locally to minimize noise coupling |
| 5 | Non-inverting Input B | Independent high-Z input for second amplifier channel; electrically isolated from Channel A |
| 6 | Inverting Input B | Independent feedback node for Channel B; supports dual-channel signal processing |
| 7 | Output B | Amplifier B output; fully independent; shares same supply pins but no crosstalk beyond 120 dB |
| 8 | VCC+ | Positive supply rail; supplies both amplifiers; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| High Input Impedance JFET Stage | 10¹² Ω input resistance - preserves signal integrity in high-Z source applications (e.g., piezoelectric sensors) |
| Internal Frequency Compensation | Unity-gain stable without external components - reduces BOM count and layout sensitivity in standard op-amp configurations |
| Output Short-Circuit Protection | Continuous safe operation under output-to-rail shorts - eliminates need for external current-limiting resistors in prototyping |
| Latch-Up Free Operation | Guaranteed immunity to parasitic SCR triggering - ensures reliability in noisy industrial environments with transient surges |
| Wide Common-Mode Range | Extends to VCC+ (±11 V with ±15 V supply) - enables direct interfacing with unbuffered ADC references or DAC outputs |

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 | Lower input bias current (30 pA typ), lower noise (18 nV/√Hz), but only 0–70 °C rating | Not qualified for industrial temperature range; unsuitable for extended ambient deployments | Select when ambient stays within commercial range and ultra-low noise is prioritized over temperature robustness |
| OPA2134PA | Higher precision (0.5 mV max Vio), lower distortion (0.00008% THD), but higher cost and SO8 footprint not identical | Requires PCB redesign due to different pad layout and thermal pad; not drop-in | Choose for audio-grade fidelity where budget allows and layout flexibility exists |
Compared with TL082ID, TL072CDR trades industrial temperature capability for slightly better noise performance, while OPA2134PA offers superior DC precision and THD at the cost of compatibility and cost-making TL082ID optimal for rugged, cost-sensitive dual-amplifier signal chains.

FAQ
What is the maximum supply voltage for TL082ID?
The absolute maximum supply voltage is ±18 V, with recommended operating range of ±6 V to ±18 V. Exceeding ±18 V risks permanent damage. Thermal derating applies above 70 °C ambient-consult Figure 13 in the datasheet for power dissipation limits versus temperature.
Does TL082ID require external compensation capacitors?
No-TL082ID features internal frequency compensation optimized for unity-gain stability. External compensation is unnecessary for standard inverting, non-inverting, or voltage-follower configurations. Uncompensated variants (e.g., TL082BCP) exist but are not applicable to this part number.
Can TL082ID drive capacitive loads directly?
It can drive ≤100 pF loads stably without isolation; larger capacitive loads (e.g., >500 pF) risk instability and ringing. For cable driving or ADC input buffering, add a 10–100 Ω series resistor between output and load to isolate capacitance and preserve phase margin.
Is TL082ID pin-compatible with TL082CP or TL082CD?
Yes-TL082ID shares identical SO8 pinout and electrical behavior with TL082CP and TL082CD. The key difference is temperature grade: ID is –40 °C to +105 °C, CP is –40 °C to +85 °C, and CD is 0 °C to +70 °C. No PCB change is needed when upgrading to industrial grade.
