Product details
Overview
TL082HIPWR from Texas Instruments is a dual JFET-input operational amplifier optimized for high-slew-rate precision signal conditioning in industrial power electronics. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, ±2.25 V to ±20 V dual-supply operation, 37 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail common-mode input range extending to VCC+. It is used in solar inverter feedback loops and motor drive current sensing stages.
For engineers reviewing the TL082HIPWR datasheet, TL082HIPWR pinout, TL082HIPWR application, or TL082HIPWR equivalent, this page provides verified electrical specifications, package-validated pin functions, real-world application context for power conversion systems, and two confirmed alternative op-amps with documented functional trade-offs.
Technical Context
The TL082HIPWR employs a JFET-input differential pair architecture enabling ultra-low input bias current (±1 pA typ) and high input impedance (>1 TΩ), critical for high-impedance sensor interfaces and integrator circuits. Its internal compensation ensures stable unity-gain operation with up to 300 pF capacitive load drive capability.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, supporting robust operation in noisy industrial environments. The device operates across –40°C to +125°C and maintains 100 dB CMRR and 125 dB open-loop gain over temperature, enabling precision DC-coupled amplification in battery test equipment and UPS control circuits.

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 | Wider offset voltage (±3 mV max), lower ESD rating (500 V HBM), no integrated EMI filters | Limited to benign lab environments; unsuitable for field-deployed solar or motor drives | Select when cost sensitivity outweighs EMI robustness and offset performance |
| OPA2134UA | Lower noise (8 nV/√Hz), higher GBW (8 MHz), but narrower supply range (±4.5 V to ±18 V) | Better for audio-grade signal chains; less tolerant of industrial rail variations | Choose for high-fidelity pro-audio mixers where THD+N <0.0001% is required |
Compared with TL082CDR, TL082HIPWR offers tighter offset and superior EMI immunity for harsh environments; versus OPA2134UA, it trades audio-grade noise performance for wider supply tolerance and industrial temperature support.

FAQ
What is the maximum capacitive load the TL082HIPWR can drive stably?
The TL082HIPWR is characterized to drive up to 300 pF capacitive load while maintaining ≥56° phase margin and stable step response. This enables direct connection to long PCB traces or ADC input capacitors without external isolation resistors, simplifying layout in motor drive current-sense circuits where TL082HIPWR buffers shunt voltage before digitization.
Does TL082HIPWR support single-supply operation?
Yes, TL082HIPWR supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing input signals referenced to ground or mid-rail in single-supply configurations-common in battery-powered test equipment where TL082HIPWR conditions sensor outputs prior to microcontroller ADC sampling.
How does the EMI rejection ratio benefit TL082HIPWR in solar inverter designs?
With 53 dB EMI rejection at 1 GHz, TL082HIPWR suppresses high-frequency noise coupled from IGBT switching in solar string inverters. This eliminates need for additional RC filtering on TL082HIPWR inputs in DC-link voltage sensing circuits, reducing bill-of-materials and preserving signal bandwidth for fast transient response.
What is the thermal resistance (RθJA) of TL082HIPWR in SOIC-8 package?
The junction-to-ambient thermal resistance (RθJA) for TL082HIPWR in SOIC-8 (D) package is 147.8°C/W. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with copper pour and thermal vias-critical for TL082HIPWR deployment in compact UPS control boards where dual-channel operation must remain within 125°C junction limit.
Is TL082HIPWR pin-compatible with legacy TL082 variants?
Yes, TL082HIPWR maintains identical SOIC-8 pinout and footprint as TL082CP, TL082CDR, and TL082ACDR. No PCB redesign is required when upgrading to TL082HIPWR for improved ESD immunity (1.5 kV HBM vs. 500 V), lower offset, or extended temperature range-making it a drop-in reliability upgrade for existing TL082HIPWR-based industrial designs.
