Product details
Overview
TL082IPT from STMicroelectronics is a high-speed JFET-input dual operational amplifier in TSSOP-8 package, rated for -40°C to 105°C operation, featuring 16 V/µs typical slew rate, 2.5 MHz gain-bandwidth product, and ±11 V input common-mode range with ±15 V supply. It serves as a precision signal conditioning and amplification stage in analog front-ends for industrial sensors and data acquisition systems.
For engineers reviewing the TL082IPT datasheet, TL082IPT pinout, TL082IPT application, or TL082IPT equivalent, key selection criteria include input bias current (≤200 pA), offset voltage drift (10 µV/°C), output short-circuit protection, and thermal resistance (120 °C/W) in compact TSSOP-8 packaging.
Technical Context
The TL082IPT integrates matched high-voltage JFET and bipolar transistors on a single monolithic die, enabling high input impedance (>10¹² Ω) and low input bias current while maintaining latch-up-free operation across its full temperature range. Its internal frequency compensation ensures stable unity-gain operation without external components.
It delivers rail-to-rail compatible output swing (±10 V into 2 kΩ) under ±15 V supply, supports differential input voltages up to ±30 V, and maintains >120 dB channel separation-critical for dual-channel signal integrity in mixed-signal instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 16 V/µs typical - enables faithful reproduction of fast transient signals up to ~1 MHz at 10 Vpp |
| Gain-Bandwidth Product | 2.5 MHz - sets usable closed-loop bandwidth for gain ≥ 10 |
| Input Offset Voltage | 3 mV max (25°C), 13 mV max (–40°C to 105°C) - defines DC accuracy in precision amplification |
| Input Bias Current | 200 pA max (25°C) - minimizes voltage error across high-impedance sensor interfaces |
| Common-Mode Range | ±11 V with ±15 V supply - supports inputs near supply rails without phase reversal |
| Supply Voltage Range | ±3 V to ±18 V (6–36 V total) - accommodates single- or dual-supply configurations |
| Thermal Resistance (J-A) | 120 °C/W (TSSOP-8) - determines maximum power dissipation before thermal derating |
Pinout & Package
TSSOP-8 (Thin Shrink Small Outline Package, 3.0 × 4.4 mm body, 0.65 mm pitch) with exposed pad for thermal enhancement per JEDEC MO-178AB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance JFET node accepting negative feedback or signal inversion |
| 2 | Non-inverting Input (Amplifier A) | High-impedance JFET node for reference or positive signal routing |
| 3 | Output (Amplifier A) | Class-AB output stage capable of ±10 V swing into 2 kΩ load |
| 4 | VCC– | Negative supply rail connection; must be decoupled locally |
| 5 | Non-inverting Input (Amplifier B) | Independent high-Z input for second channel; no crosstalk below –120 dB |
| 6 | Inverting Input (Amplifier B) | Second channel inverting input; matched to Channel A for differential pair use |
| 7 | Output (Amplifier B) | Electrically isolated output stage; supports independent loading |
| 8 | VCC+ | Positive supply rail; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| High Input Impedance | 10¹² Ω - preserves signal integrity when interfacing with piezoelectric sensors or high-R passive filters |
| Output Short-Circuit Protection | Continuous safe shorting to either rail or ground - eliminates need for external current-limiting resistors |
| Latch-Up Free Operation | Guaranteed over full temperature and supply range - prevents catastrophic failure during overvoltage transients |
| Internal Frequency Compensation | Unity-gain stable without external components - reduces BOM count and layout sensitivity |
| Wide Common-Mode Range | Extends to VCC+ - enables direct sensing of signals referenced to positive rail (e.g., current shunt monitors) |
Applications
| Industrial Sensor Signal Conditioning | Audio Pre-Amplification Stage |
|---|---|
Use Scenario: Amplifying low-level mV outputs from RTD, thermocouple, or strain gauge bridges in PLC analog input modules. IC Role / Device Role / Timing Role: Dual-channel DC-coupled instrumentation amplifier front-end with matched gain paths.

IC Role / Device Role / Timing Role: Low-noise, low-distortion dual op-amp providing 20 dB gain with minimal harmonic generation. Use Value: 15 nV/√Hz input noise and 0.01% THD at 1 kHz ensure fidelity in 16-bit audio chains without added filtering. |
| Active Filter Building Block | Dual-Channel Data Acquisition Front-End |
Use Scenario: Implementing 2nd-order Sallen-Key or multiple-feedback bandpass filters for anti-aliasing or tone detection. IC Role / Device Role / Timing Role: High-slew-rate dual op-amp enabling stable filter response up to 100 kHz with precise Q-factor control.

IC Role / Device Role / Timing Role: Dual-channel buffer/amplifier with independent power domains and matched DC performance. Use Value: >120 dB channel separation prevents crosstalk-induced measurement errors; ±11 V common-mode range accepts wide dynamic input ranges. |
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 narrower common-mode range (±10 V) and no extended temp grade | Optimized for audio and low-noise lab equipment; not qualified for industrial temp range | Select when noise and bias current dominate over temperature range and rail tolerance |
| OPA2134PA | Higher precision (0.5 mV Vos max), lower distortion (0.00008% THD), but higher cost and SO-8 only | Targeted at professional audio and medical instrumentation requiring ultra-low distortion | Choose when sub-0.1% THD and <1 µV/°C drift are mandatory, and TSSOP-8 is not required |
Compared with TL072CDR and OPA2134PA, TL082IPT offers the best balance of industrial temperature rating, output short-circuit robustness, and TSSOP-8 footprint-making it optimal for space-constrained embedded systems where reliability across environmental extremes is critical.

FAQ
What is the maximum supply voltage for TL082IPT?
The absolute maximum supply voltage is ±18 V (36 V total), but recommended operating range is ±3 V to ±18 V. Operation beyond ±18 V risks permanent damage. Derating is required above 70°C ambient due to thermal limits-maximum continuous dissipation is 680 mW at 25°C, decreasing linearly with junction temperature rise.
Does TL082IPT require external compensation capacitors?
No-TL082IPT features internal frequency compensation optimized for unity-gain stability. Adding external compensation may degrade phase margin or cause oscillation. External capacitors are only needed for specific applications like driving capacitive loads (>100 pF), where a small series resistor (e.g., 50 Ω) at the output is preferred over capacitor-based compensation.
Can TL082IPT drive a 600 Ω audio load directly?
No-it is not specified for 600 Ω loads. The datasheet guarantees ±10 V swing into 2 kΩ and ±12 V into 10 kΩ. Driving 600 Ω would exceed safe output current limits (max 40 mA short-circuit), risking thermal overload or distortion. A dedicated audio line driver or buffer stage is required for 600 Ω termination.
Is TL082IPT pin-compatible with TL072 or NE5532?
No-TL082IPT (TSSOP-8) shares the same pinout as other dual op-amps in SO-8/TSSOP-8 packages (e.g., TL072CDR, NE5532DR), but electrical behavior differs significantly: TL082 has higher input bias current and lower slew rate than NE5532, and wider common-mode range than TL072. Mechanical compatibility does not imply functional interchangeability without circuit validation.
