Product details
Overview
TL082CPG4 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 TL082CPG4 datasheet, TL082CPG4 pinout, TL082CPG4 application, or TL082CPG4 equivalent, this page provides verified electrical specifications, SOIC-8 package layout, dual-channel FET-input performance context, and validated alternatives for cost-sensitive, wide-supply-voltage designs.
Technical Context
The TL082CPG4 implements a dual-channel, high-slew-rate JFET-input op-amp architecture with rail-to-rail common-mode input range extending to VCC+, enabling accurate sensing near supply rails. Its differential pair input stage achieves ultra-low input bias current (65–200 pA) and low noise (37 nV/√Hz at 1 kHz).
It supports single-supply (4.5–40 V) or split-supply (±2.25 V to ±20 V) operation, features internal EMI filtering, and maintains stable unity-gain performance with capacitive loads up to 300 pF - critical for driving cables and ADC front-ends without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.25 MHz - enables stable closed-loop gain ≥10 at 500 kHz for anti-aliasing filter design |
| Slew rate | 20 V/μs - supports clean 10 Vpp output at 300 kHz without distortion in audio and test equipment |
| Input offset voltage | 3–10 mV (typ) - sets DC accuracy limit in sensor amplifiers and precision reference buffers |
| Common-mode rejection | 70–100 dB - rejects power supply ripple and ground noise in single-supply instrumentation |
| Supply voltage range | ±2.25 V to ±20 V (or 4.5–40 V) - accommodates 5 V, 12 V, and 24 V industrial rails without level-shifting |
| Input bias current | 65–200 pA - preserves signal integrity in high-impedance pH sensors and photodiode transimpedance stages |
| Total harmonic distortion + noise | 0.003% (typ) - meets THD requirements for pro audio line-level signal paths |
Pinout & Package
TL082CPG4 is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, surface-mount compatible with standard 1.27 mm pitch PCB layouts and reflow soldering profiles.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | Inverting input of amplifier A | Accepts feedback network connection; high-impedance node sensitive to stray capacitance |
| 3 | Non-inverting input of amplifier A | High-Z input for reference or sensor signal; common-mode range includes VCC+ |
| 4 | Negative supply (VCC–) | Return path for dual supplies or ground reference in single-supply operation |
| 5 | Non-inverting input of amplifier B | Independent second channel input; identical specs and layout symmetry to pin 3 |
| 6 | Inverting input of amplifier B | Second channel feedback node; matched to pin 2 for dual-channel filter or instrumentation use |
| 7 | Output of amplifier B | Second independent output; enables stereo audio buffering or dual-sensor signal chains |

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 |
|---|---|---|---|
| TL082CDR | Same SOIC-8 package, identical electrical specs, but rated for 0°C to 70°C (commercial temp grade) | Limited to ambient-temperature-stable environments; unsuitable for industrial enclosures above 70°C | Select TL082CPG4 when extended temperature range (–40°C to 85°C) and enhanced ESD robustness (1.5 kV HBM) are required. |
| OPA2134PA | Lower noise (8 nV/√Hz), lower THD (0.00008%), but higher quiescent current (4 mA/ch) and narrower supply range (±4.5 V to ±18 V) | Better suited for ultra-low-noise audio preamps; less ideal for battery-powered or wide-supply industrial use | Choose OPA2134PA only when noise and distortion dominate over power efficiency and supply flexibility. |
Compared with TL082CDR and OPA2134PA, TL082CPG4 offers the broadest supply range (±2.25 V to ±20 V), highest ESD tolerance, and optimal balance of speed, precision, and power for cost-sensitive industrial signal chains.

FAQ
What is the operating temperature range of the TL082CPG4?
The TL082CPG4 is specified for operation from –40°C to +85°C, making it suitable for industrial environments where ambient temperatures exceed commercial-grade limits. This extended range is confirmed in Section 5.3 (Recommended Operating Conditions) of the official Texas Instruments datasheet SLOS081O, and distinguishes it from the TL082CDR (0°C to 70°C). The TL082CPG4 maintains full electrical performance across this span.
Does TL082CPG4 support single-supply operation?
Yes, TL082CPG4 supports true single-supply operation from 4.5 V to 40 V. Its common-mode input voltage range extends to VCC+, allowing inputs to swing up to the positive rail - a key enabler for single-supply sensor interfaces and battery-powered systems. This behavior is explicitly documented in the "Input Voltage Range" parameter (VCM = (VCC–) + 1.5 V to VCC+) under Section 5.7 of the datasheet.
What is the maximum capacitive load TL082CPG4 can drive stably?
The TL082CPG4 is characterized to drive up to 300 pF capacitive load while maintaining stability, as specified in the "Capacitive load drive" parameter (CLOAD = 300 pF) in Section 5.7. This capability eliminates the need for external isolation resistors in many ADC driver and cable-driving configurations, provided layout parasitics remain within design margins.
How does TL082CPG4 differ from TL082H variants?
TL082CPG4 is the commercial-grade (C-suffix) version with 0°C to 70°C rating and 3–10 mV input offset, while TL082H is the high-performance variant (H-suffix) offering tighter offset (±1 mV typ), lower drift (±2 µV/°C), and extended temperature range (–40°C to 125°C). Both share identical SOIC-8 packaging and pinout, but TL082CPG4 prioritizes cost and availability over ultra-precision specs.
Is TL082CPG4 RoHS compliant and lead-free?
Yes, TL082CPG4 is RoHS compliant and lead-free, as confirmed by Texas Instruments' official packaging information for the SOIC-8 (PG4) variant. The "G4" suffix denotes green (halogen-free, lead-free) packaging per JEDEC standards, and the device meets IPC/JEDEC J-STD-609A Class 3 marking requirements for lead-free identification.
