Product details
Overview
TL082CD from STMicroelectronics is a general-purpose JFET-input dual operational amplifier in SO8 package, rated for 0 °C to 70 °C operation, featuring 16 V/µs typical slew rate, ±15 V input voltage range, and 2.5 MHz gain-bandwidth product - used in precision analog signal conditioning, active filtering, and sensor interface circuits.
For engineers reviewing the TL082CD datasheet, TL082CD pinout, TL082CD application, or TL082CD equivalent, this page delivers verified electrical parameters, SO8 terminal mapping, real-world use cases, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The TL082CD integrates two matched high-voltage JFET-input amplifiers on a single monolithic die, enabling dual-channel operation without crosstalk degradation (120 dB channel separation). Its internal frequency compensation ensures unity-gain stability while supporting closed-loop gains ≥5 without external compensation.
Designed for rail-to-rail compatible supply ranges (±3 V to ±18 V), it delivers ±12 V output swing into 2 kΩ at ±15 V supplies and maintains low input bias current (20–400 pA) across temperature - critical for high-impedance transducer interfaces and integrator circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables clean 100 kHz sine wave reproduction with ≤1% distortion at ±10 V output swing |
| Gain-Bandwidth Product | 2.5 MHz - supports stable closed-loop gain of 10 up to 250 kHz |
| Input Offset Voltage | 3 mV max at 25 °C - sets baseline DC error in precision DC-coupled amplifiers |
| Input Bias Current | 20 pA typical at 25 °C - preserves signal integrity in >1 MΩ source impedance applications |
| Common-Mode Range | ±11 V (min) with ±15 V supplies - allows input signals within 4 V of either rail |
| Output Short-Circuit Duration | Infinite - permits continuous safe short-circuit operation without thermal shutdown |
| Supply Voltage Range | ±3 V to ±18 V - supports dual-supply industrial and test equipment designs |
Pinout & Package
TL082CD is supplied in an 8-pin SO8 (Small Outline) package per JEDEC MS-012, with 1.27 mm pitch, gull-wing leads, and body dimensions 4.9 × 6.0 × 1.75 mm. Thermal resistance junction-to-ambient is 125 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - drives loads up to 60 mA short-circuit current |
| 2 | Inverting Input A | High-impedance JFET node - accepts differential inputs up to ±30 V |
| 3 | Non-inverting Input A | High-impedance JFET node - common-mode range extends to ±11 V |
| 4 | VCC− | Negative supply rail - must be connected before applying input signals |
| 5 | Non-inverting Input B | Second amplifier's positive input - electrically isolated from Channel A |
| 6 | Inverting Input B | Second amplifier's negative input - shares no internal nodes with Channel A |
| 7 | Output B | Amplifier B output - identical AC/DC specs to Output A |
| 8 | VCC+ | Positive supply rail - decoupling capacitor required within 10 mm |
Key Features
| Feature | Design Value |
|---|---|
| High Input Impedance | 10¹² Ω - minimizes loading on high-Z sources like piezoelectric sensors and photodiode transimpedance stages |
| Output Short-Circuit Protection | Continuous infinite-duration protection - eliminates need for external current-limiting resistors in fault-prone systems |
| Latch-Up Free Operation | Guaranteed under all valid operating conditions - prevents destructive parasitic thyristor activation during overvoltage transients |
| Low Input Offset Drift | 10 µV/°C - limits thermal-induced DC error to <100 µV over 0–70 °C ambient range |
| Wide Supply Range | ±3 V to ±18 V - supports both low-power portable instrumentation and high-dynamic-range test equipment |

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 |
|---|---|---|---|
| TL072CP | Lower input noise (18 nV/√Hz vs. 15 nV/√Hz), but higher input offset voltage (10 mV max) | Preferred in low-noise audio where offset is trimmed externally; less suitable for DC-coupled sensor amps | Select when noise dominates offset error and external trimming is feasible |
| OPA2134PA | Higher slew rate (20 V/µs), lower THD (0.00008%), but requires ±5 V minimum supply | Better for high-fidelity audio and precision DAC output buffers; not drop-in for ±3 V systems | Choose for premium audio or metrology where cost and supply headroom permit |
Compared with TL072CP and OPA2134PA, TL082CD offers superior input bias current (20 pA vs. 30 pA/10 pA) and wider supply range (±3 V to ±18 V), making it optimal for legacy industrial designs and high-impedance sensor front-ends where supply flexibility and leakage sensitivity are critical.

FAQ
What is the maximum recommended supply voltage for TL082CD?
The absolute maximum supply voltage is ±18 V per the datasheet. Operating continuously above ±15 V increases junction temperature and may reduce long-term reliability. For stable 70 °C ambient operation, ST recommends limiting total supply span to ≤30 V (e.g., +15 V/–15 V or +12 V/–12 V) with adequate PCB copper pour and airflow.
Does TL082CD require external frequency compensation?
No - TL082CD features internal frequency compensation optimized for unity-gain stability. It remains stable with closed-loop gains ≥5 without external components. Gains below 5 (e.g., voltage follower) may exhibit overshoot but remain functional; for critical low-overshoot applications, a small series resistor (10–50 Ω) at the output is recommended.
Can TL082CD drive capacitive loads directly?
It can drive ≤100 pF loads stably. Driving larger capacitive loads (e.g., cables or ADC input capacitance) risks instability and ringing. For loads >100 pF, isolate with a 50–100 Ω series resistor placed close to the output pin - this maintains phase margin while preserving bandwidth for most sensor and audio applications.
How does TL082CD differ from TL082ID?
TL082CD is rated for 0–70 °C operation in SO8 packaging, while TL082ID operates from –40 to 105 °C and is qualified for extended industrial environments. Electrical specs are identical at 25 °C, but TL082ID guarantees parameter limits across its wider temperature range - making it mandatory for outdoor or under-hood applications.
