Product details
Overview
TL082CP from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 5.25 MHz gain-bandwidth, 20 V/μs slew rate, ±15 V supply operation, and 100 dB common-mode rejection - enabling high-fidelity amplification in pro audio mixers and battery test equipment.
For engineers reviewing the TL082CP datasheet, TL082CP pinout, TL082CP application, or TL082CP equivalent, key selection criteria include input offset voltage (≤10 mV), rail-to-rail input capability (common-mode range includes VCC+), low 1.4 µVRMS 0.1–10 Hz noise, and SOIC-8 package compatibility with legacy TL072/TL082 footprints.
Technical Context
The TL082CP uses a JFET-input differential pair to achieve ultra-low input bias current (≤200 pA) and high input impedance (>1 TΩ), making it suitable for high-source-impedance sensor interfaces. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It operates across ±2.25 V to ±20 V supplies (4.5 V to 40 V total), supports common-mode input voltages extending to the positive rail, and features output short-circuit protection plus EMI/RF filtering - critical for motor drive feedback loops and UPS control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.25 MHz - enables stable closed-loop operation up to 100 kHz at gain ≥50 |
| Slew rate | 20 V/μs - supports fast transient response in pulse-amplifier and active filter stages |
| Input offset voltage | 3–10 mV - defines DC accuracy limit in precision instrumentation front-ends |
| Common-mode input range | Includes VCC+ - allows direct sensing of signals referenced to positive supply rail |
| Supply voltage range | ±2.25 V to ±20 V - compatible with standard ±5 V, ±12 V, and ±15 V analog rails |
| Input bias current | 65–200 pA - minimizes voltage error in high-impedance photodiode or piezo sensor interfaces |
| CMRR | 70–100 dB - rejects power-supply and ground-noise coupling in noisy industrial environments |
Pinout & Package
TL082CP is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and standard through-hole mounting. Pin 1 is marked by a notch or dot; leads are tin-lead plated for solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier A | Provides buffered, low-impedance output signal for driving downstream stages |
| 2 | Inverting input of Amplifier A | Accepts feedback network connection for configuring inverting gain stages |
| 3 | Non-inverting input of Amplifier A | Connects to reference or sensor signal in non-inverting amplifier configurations |
| 4 | Negative supply (VCC–) | Reference node for dual-supply operation; must be decoupled to ground |
| 5 | Non-inverting input of Amplifier B | Enables independent signal path for second channel in dual-amplifier applications |
| 6 | Inverting input of Amplifier B | Supports differential or inverting configuration for second amplifier channel |
| 7 | Output of Amplifier B | Delivers second independent amplified output without crosstalk (typical channel separation >100 dB) |
| 8 | Positive supply (VCC+) | Power rail for both amplifiers; requires local 0.1 μF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input architecture | Enables ≤200 pA input bias current for minimal loading of high-Z sources like pH electrodes |
| Output short-circuit protection | Prevents device failure during accidental output-to-ground faults in motor driver feedback paths |
| Integrated EMI/RF filters | Suppresses 1 GHz interference in switch-mode power supply environments (EMIRR = 53 dB) |
| Wide supply range | Operates from ±2.25 V to ±20 V, supporting both low-voltage portable and high-voltage industrial designs |
| Low 0.1–10 Hz noise | 1.4 µVRMS - critical for DC-stable amplification in battery test equipment and precision transducer interfaces |

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 |
|---|---|---|---|
| TL082CDR | SOIC-8 package; same electrical specs but surface-mount footprint | Preferred for automated PCB assembly and space-constrained designs | Select TL082CDR when board layout requires SMT placement or thermal performance demands lower RθJA (95°C/W vs 85°C/W for PDIP) |
| TL072CP | Lower 18 nV/√Hz noise at 1 kHz; identical pinout and supply range | Better suited for ultra-low-noise audio preamps where offset voltage <5 mV is acceptable | Choose TL072CP only if noise dominates design requirements and offset voltage tolerance allows ≥6 mV drift |
Compared with TL082CDR and TL072CP, the TL082CP offers through-hole manufacturability and higher input bias current tolerance (≤200 pA vs ≤150 pA), making it optimal for legacy industrial control boards requiring field-replaceable components and robustness against contamination.

FAQ
What is the maximum supply voltage for TL082CP?
The TL082CP supports a total supply voltage range of 4.5 V to 40 V, corresponding to ±2.25 V to ±20 V dual supplies. Absolute maximum ratings specify 42 V for continuous operation, but recommended operation stays within 40 V to ensure long-term reliability and specified performance across temperature.
Does TL082CP have rail-to-rail input capability?
The TL082CP features a common-mode input voltage range that extends to the positive supply rail (VCC+), but does not reach the negative rail - minimum common-mode voltage is (VCC–) + 4 V under typical conditions. This allows high-side sensing but excludes true rail-to-rail input operation.
Can TL082CP drive capacitive loads?
Yes, the TL082CP can safely drive capacitive loads up to 300 pF while maintaining stability, as confirmed by its internal compensation and phase margin of 56° at G = +1 with 20 pF load. For larger loads, external isolation resistance is recommended to prevent peaking or oscillation.
What is the input offset voltage specification for TL082CP?
The TL082CP has a typical input offset voltage of 3 mV and a maximum of 10 mV at 25°C, with full-range (0°C to 70°C) max of 13 mV. This parameter directly impacts DC accuracy in precision integrators and sensor amplifiers, requiring calibration or trimming in sub-mV-error applications.
Is TL082CP pin-compatible with other dual op-amps?
Yes, TL082CP uses the industry-standard 8-pin PDIP pinout shared with TL072CP, LM358N, and NE5532N. However, functional differences - such as JFET vs bipolar input, noise profile, and slew rate - require circuit validation when substituting; it is not a drop-in replacement for all use cases.
