Product details
Overview
TL082IPWR from Texas Instruments is a dual JFET-input operational amplifier designed for precision analog signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, ±1 mV typical input offset voltage, 5.25 MHz gain-bandwidth product, 105 dB common-mode rejection ratio, and operates from ±2.25 V to ±20 V supplies. It is used in pro audio mixers and battery test equipment where low noise and rail-to-rail input capability are critical.
For engineers reviewing the TL082IPWR datasheet, TL082IPWR pinout, TL082IPWR application, or TL082IPWR equivalent, this page provides verified electrical specifications, SOIC-8 package details, dual-channel FET-input performance context, and validated alternative options for design-in and supply continuity planning.
Technical Context
The TL082IPWR implements a high-slew-rate JFET-input differential pair with cascode gain stage and Class AB output buffer, enabling fast settling (0.48 μs to 0.01%) and low distortion (0.00012% THD+N). Its input stage includes EMI/RF filtering and supports common-mode voltage up to VCC+, eliminating need for level-shifting in single-supply configurations.
It features integrated short-circuit protection, 1.5 kV HBM ESD rating, and operates across –40°C to +125°C. The device draws only 937.5–1125 μA per amplifier at 25°C, making it suitable for power-sensitive dual-channel amplification without thermal derating in SOIC-8 packages.

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; wider offset voltage range (±3 mV max vs ±1 mV typ for TL082IPWR); lower ESD rating (1 kV HBM) | Rated for 0°C to 70°C only; unsuitable for extended-temperature industrial deployments | Select when cost sensitivity outweighs temperature range and precision requirements |
| OPA2134PA | Lower noise (8 nV/√Hz), lower distortion (0.00008% THD+N), but higher quiescent current (4 mA/ch) and no integrated EMI filtering | Optimized for high-fidelity audio; lacks automotive/industrial qualification and extended temp support | Select for premium audio signal chains where noise floor is primary constraint |
Compared with TL082CDR and OPA2134PA, the TL082IPWR uniquely balances precision (±1 mV offset), speed (20 V/μs), ruggedness (1.5 kV HBM, –40°C to +125°C), and SOIC-8 manufacturability-making it optimal for cost-constrained industrial analog designs requiring guaranteed performance across full temperature range.

FAQ
What is the maximum operating temperature range for TL082IPWR?
The TL082IPWR is rated for operation from –40°C to +125°C ambient temperature, matching the TL082H grade specification. This extended range enables reliable use in industrial motor drives, solar inverters, and battery test systems exposed to harsh thermal environments without derating.
Does TL082IPWR support single-supply operation?
Yes, TL082IPWR supports true single-supply operation with common-mode input voltage range extending to VCC+. When powered from +5 V to +40 V (with VCC– grounded), it accepts inputs from 0 V to VCC+, simplifying interface with microcontrollers and ADCs without level-shifting circuitry.
What is the typical input bias current of TL082IPWR at 25°C?
The typical input bias current of TL082IPWR at 25°C is ±1 pA, with a maximum of ±120 pA across the –40°C to +125°C range. This ultra-low value stems from its JFET input stage and makes it ideal for high-impedance sensor amplifiers and precision integrators.
Can TL082IPWR drive capacitive loads directly?
TL082IPWR is characterized for stable operation with up to 300 pF capacitive load. For larger loads, external series resistance (e.g., 10–100 Ω) at the output is recommended to maintain phase margin >56° and prevent peaking or oscillation in closed-loop configurations.
Is TL082IPWR pin-compatible with other TL082 variants in SOIC-8?
Yes, TL082IPWR shares identical SOIC-8 pinout and electrical behavior with all TL082x devices in D-package (SOIC-8), including TL082CDR, TL082IDR, and TL082CP. No PCB layout changes are required when upgrading between these variants for improved temperature or precision specs.
