Product details
Overview
TL082CPWR 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, low 37 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail common-mode input range extending to VCC+. It is used in pro audio mixers and battery test equipment where low distortion (0.003% THD+N) and high CMRR (100 dB) are critical.
For engineers reviewing the TL082CPWR datasheet, TL082CPWR pinout, TL082CPWR application, or TL082CPWR equivalent, this page provides verified electrical specifications, TSSOP-8 package layout, dual-channel functional context, and validated alternative options for cost-sensitive, wide-supply analog designs requiring FET-input performance and EMI robustness.
Technical Context
The TL082CPWR implements a dual-channel, high-slew-rate JFET-input op-amp architecture with fully differential input stages and Class AB output stages. Its input stage supports common-mode voltages up to VCC+, enabling single-supply operation with ground-referenced inputs when VCC– = GND.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, operating across –40°C to 85°C (TL082C grade). The device maintains stable unity-gain performance with capacitive loads up to 300 pF and exhibits 56° phase margin under standard test conditions (G = +1, RL = 10 kΩ, CL = 20 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent amplifiers - enables stereo signal paths or differential pair implementation without external matching. |
| Gain-bandwidth product | 5.25 MHz - supports stable closed-loop operation up to ~500 kHz at G = 10, suitable for active filters and broadband instrumentation. |
| Slew rate | 20 V/μs - ensures faithful reproduction of fast transients in audio and control loop applications without slew-induced distortion. |
| Input voltage noise density | 37 nV/√Hz at 1 kHz - low-noise performance critical for sensor front-ends and low-level signal amplification. |
| Common-mode input range | Extends to VCC+ - allows direct interface with microcontroller DAC outputs or other rail-referenced sources in single-supply systems. |
| Supply voltage range | ±2.25 V to ±20 V (4.5 V to 40 V total) - accommodates both low-voltage portable and high-voltage industrial power rails. |
| THD+N | 0.003% at 1 kHz - meets pro-audio fidelity requirements for mixing and monitoring circuits. |
Pinout & Package
TSSOP-8 (PW) package: 4.4 mm × 3.0 mm body, 0.65 mm pitch, thermally enhanced exposed pad (not electrically connected), rated for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives feedback network or load; capable of sourcing/sinking ±26 mA short-circuit current. |
| 2 | IN– A | Inverting input of Amplifier A - high-impedance (6 TΩ || 1 pF) JFET node; sensitive to PCB leakage and guarding requirements. |
| 3 | IN+ A | Non-inverting input of Amplifier A - same high-impedance characteristics as IN– A; used for unity-gain buffers or non-inverting configurations. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with ≥0.1 µF ceramic capacitor; shared between both amplifiers. |
| 5 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Amplifier A; enables independent dual-channel operation. |
| 6 | IN– B | Inverting input of Amplifier B - identical input structure to IN– A; supports matched dual feedback networks. |
| 7 | OUT B | Amplifier B output - independent drive capability; no crosstalk specification given, but channel separation is 1 µV/V at DC. |
| 8 | VCC+ | Positive supply rail - shared supply node; requires local decoupling; supports rail-to-rail common-mode input swing. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±120 pA typical - minimizes voltage error in high-impedance sensor interfaces (e.g., photodiode transimpedance amps). |
| Output short-circuit protection | Continuous safe operation into ground or supply - eliminates need for external current-limiting resistors in fault-prone environments. |
| EMI rejection ratio | 53 dB at 1 GHz - suppresses RF interference in noisy industrial or switching-power-supply adjacent layouts. |
| Wide supply range | 4.5 V to 40 V total - supports single-supply 5 V logic interfacing and dual-supply ±15 V legacy analog systems without redesign. |
| Low offset voltage drift | ±2 µV/°C - ensures stable DC accuracy over temperature in precision measurement front-ends without frequent recalibration. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082IPWR | Wider temperature range (–40°C to +125°C vs. –40°C to +85°C); otherwise identical AC/DC specs and pinout. | Required for under-hood automotive or industrial ambient above 85°C; not needed for commercial-grade audio or lab equipment. | Select TL082IPWR only if extended temperature operation is mandatory; TL082CPWR suffices for most indoor, controlled-environment designs. |
| TL072CPWR | Lower input voltage noise (18 nV/√Hz vs. 37 nV/√Hz), lower quiescent current (1.4 mA/ch vs. 2.5 mA/ch), but reduced output drive (±10 mA vs. ±26 mA). | Better for ultra-low-noise, low-power sensor nodes; less suitable for driving moderate capacitive loads or low-impedance cables. | Choose TL072CPWR when noise budget is tighter and load is light; retain TL082CPWR when driving 2 kΩ+ loads or requiring higher short-circuit robustness. |
Compared with TL082IPWR, TL082CPWR trades extended temperature rating for lower cost and sufficient performance in commercial environments; versus TL072CPWR, it prioritizes output drive and ruggedness over minimal noise-making TL082CPWR optimal for general-purpose industrial analog signal chains where reliability and versatility outweigh ultra-low-noise optimization.

FAQ
What is the maximum capacitive load the TL082CPWR can drive stably?
The TL082CPWR is characterized for stable operation with capacitive loads up to 300 pF under unity-gain conditions (G = +1, RL = 10 kΩ). Driving heavier loads may require isolation resistors or compensation networks to maintain 56° phase margin and prevent peaking or oscillation, as confirmed in the datasheet's Figure 5-25 and Section 5.7.
Does the TL082CPWR support single-supply operation?
Yes, the TL082CPWR supports true single-supply operation: its common-mode input voltage range extends to VCC+, allowing inputs to swing from VCC– (e.g., ground) up to the positive rail. For proper output swing, ensure VCC– is referenced to system ground and use appropriate biasing-verified in Section 5.3 Recommended Operating Conditions.
What is the input offset voltage specification for TL082CPWR?
The TL082CPWR (C-grade) has a maximum input offset voltage of 10 mV at 25°C and full temperature range (0°C to 70°C), with a typical value of 3 mV. This is distinct from the TL082H variant (1 mV typ), as confirmed in Table 5.8 Electrical Characteristics (DC) of the official datasheet.
Is the TL082CPWR pin-compatible with other TL082 variants in TSSOP-8?
Yes, all TL082x variants-including TL082CPWR, TL082IPWR, and TL082HPWR-use identical TSSOP-8 (PW) packaging and share the exact same pinout per Table 4-3. No PCB layout changes are required when upgrading between C, I, or H grades in the same package.
What thermal metrics apply to the TL082CPWR in TSSOP-8?
The TL082CPWR in PW (TSSOP-8) package has a junction-to-ambient thermal resistance (RθJA) of 200.3°C/W and junction-to-case (top) thermal resistance (RθJC(top)) of 89.4°C/W, per Section 5.5 Thermal Information for Dual Channel. These values assume JEDEC-standard board layout and define maximum power dissipation limits for continuous operation.
