Product details
Overview
TL082CP/NOPB from Texas Instruments is a dual JFET-input operational amplifier with 4 MHz gain bandwidth, 13 V/μs slew rate, and 15 mV max input offset voltage. It operates from ±18 V supplies, delivers ±13.5 V output swing into 10 kΩ, and is used in active filters, tone controls, and instrumentation amplifiers requiring high input impedance (10¹² Ω) and low input bias current (50 pA).
For engineers reviewing the TL082CP/NOPB datasheet, TL082CP/NOPB pinout, TL082CP/NOPB application, or TL082CP/NOPB equivalent, this page provides verified electrical parameters, PDIP-8 package details, real-world use cases, and validated alternative options for industrial signal conditioning and analog front-end designs.
Technical Context
The TL082CP/NOPB integrates two independent JFET-input op-amp channels using BI-FET II™ technology, enabling internally trimmed offset voltage and matched high-voltage JFET pairs. Its architecture supports rail-to-rail common-mode input range up to ±15 V and delivers stable performance across 0°C to +70°C ambient temperature.
Each channel features zener-based biasing for operation down to ±6 V supplies, while maintaining 70 dB minimum CMRR and PSRR. The device exhibits low 1/f noise corner at 50 Hz and fast 2 μs settling time to 0.01%, making it suitable for precision DC-coupled and wideband AC applications without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 4 MHz - Enables stable unity-gain stable operation up to 4 MHz or closed-loop gain of 10 at 400 kHz. |
| Slew Rate | 13 V/μs - Supports clean reproduction of 2 Vpp signals up to ~2 MHz without slew-induced distortion. |
| Input Offset Voltage | 15 mV max - Limits DC error in precision integrators and summing amplifiers without external nulling. |
| Input Bias Current | 50 pA typical - Permits use with high-impedance sensors (e.g., piezoelectric, photodiode) without significant leakage error. |
| Supply Voltage Range | ±18 V - Allows operation with standard bipolar lab supplies and compatibility with legacy ±15 V systems. |
| Output Voltage Swing | ±13.5 V into 10 kΩ - Delivers >90% of rail-to-rail swing, reducing headroom loss in single-supply derived rails. |
| Common-Mode Input Range | ±15 V - Accepts inputs extending to supply rails, simplifying level-shifting in multi-stage analog chains. |
Pinout & Package
TL082CP/NOPB uses an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot on the package top edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance JFET gate node; accepts differential input signals referenced to non-inverting input (Pin 2). |
| 2 | Non-Inverting Input (Amplifier A) | High-impedance JFET gate node; sets reference point for A-channel differential input stage. |
| 3 | Output (Amplifier A) | Class AB push-pull output capable of sourcing/sinking ≥10 mA into resistive loads. |
| 4 | Negative Supply (V−) | Common return for both amplifiers; must be connected to system ground or negative rail. |
| 5 | Non-Inverting Input (Amplifier B) | Independent high-impedance input for second amplifier channel; electrically isolated from Channel A. |
| 6 | Inverting Input (Amplifier B) | Second differential input node; used with Pin 5 for B-channel feedback configurations. |
| 7 | Output (Amplifier B) | Second independent output; supports dual-channel functions like stereo tone control or dual-sensor conditioning. |
| 8 | Positive Supply (V+) | Common power rail for both amplifiers; decoupling capacitor required near Pin 8 for stability. |
Key Features

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/NOPB | Lower input noise (18 nV/√Hz vs. 25 nV/√Hz), same pinout and GBW, but higher cost and tighter offset spec (10 mV max). | Better suited for low-noise audio preamps; less ideal for cost-sensitive industrial signal chains where TL082CP/NOPB's 15 mV offset is acceptable. | Select TL072CP/NOPB only when noise performance dominates over cost and availability. |
| RC4558P | Bipolar input (not JFET), higher IB (300 nA), lower GBW (3 MHz), but wider temp range (−40°C to +85°C) and lower price. | Acceptable for general-purpose amplification where input impedance >1 MΩ suffices and thermal drift is not critical. | Choose RC4558P for non-precision, high-volume applications where JFET benefits are unnecessary. |
Compared with TL072CP/NOPB and RC4558P, TL082CP/NOPB offers the optimal balance of JFET input performance, cost, and industrial temperature compliance-delivering 50 pA bias current and 10¹² Ω impedance at lower unit cost than TL072, while outperforming RC4558P in high-Z sensor interfacing and low-drift DC applications.

FAQ
What is the maximum supply voltage rating for TL082CP/NOPB?
The TL082CP/NOPB has an absolute maximum supply voltage rating of ±18 V. Operation beyond this limit risks permanent damage. For reliable long-term use, TI recommends staying within ±15 V under normal conditions, especially when driving heavy loads or operating at elevated temperatures. The TL082CP/NOPB maintains full specification compliance across its rated 0°C to +70°C ambient range at ±15 V.
Does TL082CP/NOPB support single-supply operation?
TL082CP/NOPB is specified for dual-supply operation (±15 V typical), but can function in single-supply configurations with proper input/output biasing. Its input common-mode range extends to the negative rail, allowing use with ground-referenced inputs when V− = 0 V. However, output swing is asymmetric in single-supply mode, and performance metrics like CMRR degrade near rail extremes. The TL082CP/NOPB datasheet does not guarantee specifications under true single-supply conditions.
What is the input offset voltage specification for TL082CP/NOPB?
The TL082CP/NOPB has a maximum input offset voltage of 15 mV at 25°C, with a typical value of 5 mV. Over the full 0°C to +70°C temperature range, the maximum offset increases to 20 mV. Its average temperature coefficient is 10 μV/°C, meaning offset drift remains predictable and bounded. This specification applies per amplifier channel and is measured with RS = 10 kΩ.
Is TL082CP/NOPB pin-compatible with LM358?
No, TL082CP/NOPB is not pin-compatible with LM358. TL082CP/NOPB uses an 8-pin PDIP package with dual JFET inputs, while LM358 uses the same 8-pin PDIP footprint but features dual bipolar inputs and different pin assignments (e.g., LM358 Pin 1 is Output A; TL082CP/NOPB Pin 1 is Inverting Input A). Direct substitution would cause functional failure. TL082CP/NOPB is pin-compatible with LM1558 and other TL082 variants.
What package type and RoHS status does TL082CP/NOPB have?
TL082CP/NOPB is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with NIPDAU (Nickel/Palladium/Gold) lead finish and RoHS-compliant materials. It carries a "Level-1-NA-UNLIM" moisture sensitivity rating, indicating no floor life limitation and no bake requirement prior to soldering. The part marking on the package reads "TL082 CP", confirming the PDIP-8 variant.
