Product details
Overview
TL082CP/PB from Texas Instruments is a dual JFET-input operational amplifier optimized for high-speed, low-noise analog signal conditioning in industrial and consumer systems. It delivers 4 MHz gain bandwidth, 13 V/μs slew rate, 15 mV max input offset voltage, 50 pA typical input bias current, and 10¹² Ω input impedance - enabling precision amplification in active filters, tone controls, and sensor front-ends.
For engineers reviewing the TL082CP/PB datasheet, TL082CP/PB pinout, TL082CP/PB application, or TL082CP/PB equivalent, this page provides verified electrical specifications, PDIP-8 package details, real-world use cases, and validated alternative op-amps for design migration or second-sourcing.
Technical Context
The TL082CP/PB uses BI-FET II™ technology with internally trimmed JFET input stages, delivering matched high-voltage input devices that minimize bias and offset currents while sustaining wide bandwidth and fast transient response. Its zener-biased internal circuitry supports stable operation from ±6 V to ±18 V supplies.
It features rail-to-rail input common-mode range (±11 V at ±15 V supply), 70 dB minimum CMRR and PSRR, and low 1/f noise corner at 50 Hz - making it suitable for DC-coupled instrumentation and audio-grade signal paths where low drift and low distortion (<0.02% THD) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 4 MHz - enables stable unity-gain buffer or closed-loop gain ≥10 up to ~400 kHz without phase margin loss. |
| Slew Rate | 13 V/μs - supports clean 20 kHz full-scale sine output into 10 kΩ load without slewing distortion. |
| Input Offset Voltage | 15 mV max - sets worst-case DC error floor in precision DC amplifiers without external trimming. |
| Input Bias Current | 50 pA typical - allows use with high-impedance sources (e.g., piezoelectric sensors, photodiode transimpedance) without significant offset shift. |
| Input Impedance | 10¹² Ω - minimizes loading on high-Z passive networks like RC filters and tone control potentiometers. |
| Supply Voltage Range | ±18 V max - supports dual-supply industrial signal chains operating at ±15 V, with derated performance below ±6 V. |
| Operating Temperature | 0°C to +70°C - qualified for commercial-grade embedded systems, not extended or automotive temperature ranges. |
Pinout & Package
TL082CP/PB is housed in an 8-pin plastic dual in-line package (PDIP), designated P0008E per TI's package numbering system. The package has 0.3-inch body width, 0.1-inch lead pitch, and through-hole mounting compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - drives loads up to ±13.5 V swing into 10 kΩ; limited current capability (~10 mA short-circuit). |
| 2 | Inverting Input A | High-impedance JFET node - accepts feedback networks; sensitive to layout-induced noise due to 50 pA bias current. |
| 3 | Non-Inverting Input A | High-impedance JFET node - used for reference or sensor connection; common-mode range extends to ±11 V. |
| 4 | V− | Negative supply rail - must be connected; reverse polarity causes destructive current flow. |
| 5 | Non-Inverting Input B | Independent high-Z input for second channel - identical specs to Pin 3; no internal crosstalk beyond −120 dB coupling. |
| 6 | Inverting Input B | Independent high-Z input for second channel - matches Pin 2; enables dual-channel configurations without interaction. |
| 7 | Output B | Amplifier B output - electrically isolated from Output A; shares same supply rails and thermal environment. |
| 8 | V+ | Positive supply rail - must be connected; supply rejection ratio ≥70 dB ensures immunity to ripple up to 100 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Internally trimmed offset voltage | 15 mV max eliminates need for external nulling pots in cost-sensitive audio and industrial amplifiers. |
| Low input noise voltage | 16 nV/√Hz at 1 kHz enables high-fidelity preamplification of low-level signals without dominant op-amp contribution. |
| Fast settling time | 2 μs to 0.01% supports accurate sample-and-hold and D/A converter buffering in data acquisition systems. |
| Low total harmonic distortion | ≤0.02% at 20 Vp-p, 20 Hz–20 kHz ensures minimal coloration in active tone controls and line drivers. |
| Wide common-mode input range | ±11 V at ±15 V supply allows direct interfacing with bipolar sensor outputs without level-shifting circuitry. |
Applications
| Active Audio Tone Control | Instrumentation Amplifier Front-End |
|---|---|
Use Scenario: Three-band bass/mid/treble equalization in consumer audio mixers and guitar effects pedals using linear-taper potentiometers. IC Role / Device Role / Timing Role: Dual op-amp configured as two independent gain stages (inverting/non-inverting) with shared feedback network for frequency-selective boost/cut. Use Value: High input impedance prevents loading of passive RC networks; low THD preserves tonal clarity across 20 Hz–20 kHz bandwidth. |
Use Scenario: High-CMRR differential measurement of bridge-based strain gauges or thermopile outputs in industrial sensors. IC Role / Device Role / Timing Role: First-stage amplifier in improved instrumentation topology (Figure 29), providing matched gain and bias cancellation before final difference stage. Use Value: 100 dB typical CMRR and <200 pA input offset current minimize common-mode errors and thermal drift in millivolt-level signals. |
| 4th-Order Butterworth Filter | Ohms-to-Volts Transducer Interface |
Use Scenario: Anti-aliasing or reconstruction filtering in 16-bit ADC/DAC signal chains requiring sharp roll-off and linear phase near cutoff. IC Role / Device Role / Timing Role: Dual op-amp implementing cascaded Sallen-Key stages - one per amplifier - for 24 dB/octave attenuation beyond 10 kHz. Use Value: 4 MHz GBW ensures filter stability and minimal passband gain error; low noise avoids degrading SNR of high-resolution converters. |
Use Scenario: Linear conversion of resistance changes (e.g., RTD, thermistor, or potentiometer wiper position) into calibrated voltage outputs. IC Role / Device Role / Timing Role: Constant-current source + precision buffer in Figure 32 configuration, where TL082CP/PB drives feedback loop and buffers output. Use Value: 10¹² Ω input impedance prevents current-source loading; 15 mV offset limits absolute error to <0.15% FS in 10 kΩ full-scale designs. |
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 → 12 nV/√Hz), lower IB (50 pA → 30 pA), but same GBW (4 MHz) and slew rate (13 V/μs). | Preferred for ultra-low-noise audio preamps; less suitable where higher input capacitance (TL072) may destabilize capacitive feedback networks. | Choose TL072CP when noise dominates design requirements and layout accommodates its slightly higher input capacitance. |
| RC4558CP | Bipolar input (not JFET); higher IB (300 nA), higher VOS (5 mV typ, 15 mV max), lower GBW (3 MHz), but wider temp range (−25°C to +85°C). | Acceptable for cost-driven general-purpose amplification where high-Z sources or low noise are not required. | Choose RC4558CP only for non-critical DC-coupled applications with moderate source impedance (<100 kΩ) and relaxed noise/offset specs. |
Compared with TL082CP/PB, TL072CP offers measurable noise and bias current improvements for sensitive analog paths, while RC4558CP trades JFET advantages for broader temperature tolerance and lower unit cost - neither is pin-compatible nor drop-in; both require validation of loop stability and DC error budget.

FAQ
What is the maximum supply voltage rating for TL082CP/PB?
The TL082CP/PB supports a maximum supply voltage of ±18 V across V+ and V− pins. Operation beyond this limit risks permanent damage due to junction breakdown. At ±15 V, it delivers full specified performance including 13 V/μs slew rate and 4 MHz gain bandwidth. Derating is required above ±15 V, and operation below ±6 V reduces gain bandwidth and slew rate.
Does TL082CP/PB have rail-to-rail input or output capability?
No, TL082CP/PB does not feature rail-to-rail input or output. Its input common-mode voltage range is specified as ±11 V at ±15 V supply, meaning inputs must stay ≥3 V away from each rail. Output swing is ±12 V min into 10 kΩ, limiting usable dynamic range to ~24 V peak-to-peak under nominal conditions - insufficient for true rail-to-rail operation.
Can TL082CP/PB drive a 2 kΩ load across the full temperature range?
Yes, TL082CP/PB is specified to drive ±10 V into a 2 kΩ load over the full 0°C to +70°C operating range. This capability is explicitly guaranteed in the DC Electrical Characteristics table. Driving heavier loads (e.g., ≤1 kΩ) may cause increased output voltage droop and potential current limiting, especially on negative swings.
Is TL082CP/PB suitable for automotive applications?
No, TL082CP/PB is rated for 0°C to +70°C commercial operation and is not qualified to AEC-Q100 standards. For automotive use, TI offers the TL082-Q1 variant, which undergoes extended temperature testing (−40°C to +125°C) and failure analysis per automotive reliability requirements. TL082CP/PB should not be deployed in safety-critical or engine-compartment environments.
How does TL082CP/PB compare to LM358 in terms of input stage architecture?
TL082CP/PB uses JFET-input transistors, delivering 50 pA typical input bias current and 10¹² Ω input impedance, whereas LM358 uses bipolar NPN input transistors with ~45 nA bias current and ~2 MΩ input impedance. This makes TL082CP/PB superior for high-impedance sensor interfaces and low-drift integrators, while LM358 is better suited for low-voltage single-supply applications where JFET gate leakage is unnecessary.
