Product details
Overview
TL082CPWRG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for precision AC and DC amplification in industrial and audio signal chains. It delivers 5.25 MHz gain-bandwidth, 20 V/μs slew rate, ±15 V supply operation, 100 dB CMRR, and 0.003% THD+N at 1 kHz - enabling high-fidelity signal conditioning in pro audio mixers and motor drive feedback loops.
For engineers reviewing the TL082CPWRG4 datasheet, TL082CPWRG4 pinout, TL082CPWRG4 application, or TL082CPWRG4 equivalent, this page provides verified electrical specs, TSSOP-8 package layout, real-world use cases in UPS systems and battery test equipment, and two validated alternative parts with documented functional and application differences.
Technical Context
The TL082CPWRG4 implements a dual-channel, high-slew-rate JFET-input architecture with rail-to-rail common-mode input range extending to VCC+, enabling robust operation in single-supply configurations. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, supporting reliable deployment in electrically noisy environments such as solar inverters and servo drive control modules without external filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 5.25 MHz - supports stable closed-loop operation up to ~500 kHz at G = 10 |
| Slew rate | 20 V/μs - enables clean 10 Vpp output at 100 kHz without slewing distortion |
| Input offset voltage | 3 mV (max) - limits DC error to ≤30 mV in unity-gain buffer with ±15 V supplies |
| CMRR | 100 dB (min) - rejects 100 µV of common-mode interference per 10 V input swing |
| THD+N | 0.003% (typ) at 1 kHz - meets pro-audio line-level signal fidelity requirements |
| Supply voltage range | ±2.25 V to ±20 V - operates from low-voltage portable systems to industrial ±15 V rails |
| Input bias current | 65 pA (max) - allows use with high-impedance sensor sources (>100 MΩ) |
Pinout & Package
Packaged in an 8-pin TSSOP (PW), the TL082CPWRG4 uses a surface-mount footprint measuring 3.0 mm × 4.4 mm × 1.2 mm with 0.65 mm lead pitch, suitable for high-density PCB layouts in space-constrained UPS and motor drive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives feedback network or next-stage load directly |
| 2 | IN– A | Inverting input for channel A - connects to feedback resistor or summing junction |
| 3 | IN+ A | Non-inverting input for channel A - accepts high-impedance sensor or reference signals |
| 4 | VCC– | Negative supply rail - must be decoupled with ≥0.1 µF ceramic capacitor near pin |
| 5 | IN+ B | Non-inverting input for channel B - electrically isolated from channel A inputs |
| 6 | IN– B | Inverting input for channel B - supports independent gain configuration per channel |
| 7 | OUT B | Amplifier B output - usable for differential output stages or dual-path signal processing |
| 8 | VCC+ | Positive supply rail - shared power path for both amplifiers; requires local decoupling |

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; identical electrical specs but 1.75 mm height vs 1.2 mm for TSSOP | Preferred where board space allows larger footprint and thermal mass is beneficial | Select TL082CDR for through-hole prototyping or legacy SOIC-compatible designs |
| TL072CP | Lower input noise (18 nV/√Hz), lower quiescent current (1.4 mA/ch), but 100 mV higher input offset voltage (6 mV max) | Better suited for low-power, low-noise audio preamps; less ideal for precision DC-coupled sensing | Choose TL072CP when noise performance outweighs DC accuracy in battery-powered audio gear |
Compared with TL082CDR and TL072CP, the TL082CPWRG4 offers the lowest profile (TSSOP-8), best DC precision (3 mV VOS max), and highest EMI immunity (53 dB at 1 GHz), making it optimal for compact, noise-immune industrial signal conditioning where layout density and EMC robustness are critical.

FAQ
What is the maximum supply voltage for TL082CPWRG4?
The TL082CPWRG4 supports a total supply voltage (VCC+ to VCC–) of up to ±20 V (40 V total), with recommended operating range of ±2.25 V to ±20 V. Absolute maximum rating is 42 V for non-NS/PS packages - exceeding this risks permanent damage. Operation at ±15 V is standard for industrial and audio applications.
Does TL082CPWRG4 have rail-to-rail input capability?
Yes, the TL082CPWRG4 features a common-mode input voltage range that extends to VCC+, satisfying rail-to-rail input operation on the positive side. The lower limit is (VCC–) + 1.5 V at 25°C, so true rail-to-rail input is not achieved on the negative rail - but it exceeds most competing JFET-input op-amps in upper-range coverage.
Can TL082CPWRG4 drive capacitive loads?
Yes, the TL082CPWRG4 is specified to drive capacitive loads up to 300 pF while maintaining stability. This is confirmed in the datasheet's "Capacitive load drive" parameter (CLOAD = 300 pF). For loads >300 pF, external isolation resistance (e.g., 50 Ω in series with output) is recommended to prevent peaking or oscillation.
What is the input offset voltage specification for TL082CPWRG4?
The TL082CPWRG4 has a maximum input offset voltage of 3 mV at 25°C (per TL08xC grade specifications). Over full temperature range (0°C to 70°C), the max is 13 mV. This value is confirmed in Section 5.8 of the TI datasheet under "Electrical Characteristics (DC)" for TL08xC devices.
Is TL082CPWRG4 pin-compatible with other TL082 variants?
Yes, TL082CPWRG4 shares identical pinout with all TL082x dual op-amps in TSSOP-8 (PW) packaging, including TL082IDR, TL082CPW, and TL082IPWR. Pin functions match Table 4-3 in the datasheet: pins 1/7 = outputs, 2/3/5/6 = inputs, 4/8 = supplies. No PCB redesign is needed when substituting within same package type.
