Product details
Overview
TL082IPG4 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, 125 dB open-loop gain, and operates from ±2.25 V to ±20 V supplies. It is used in pro audio mixers and battery test equipment where low noise (37 nV/√Hz) and rail-to-rail common-mode input (including VCC+) are critical.
For engineers reviewing the TL082IPG4 datasheet, TL082IPG4 pinout, TL082IPG4 application, or TL082IPG4 equivalent, this page provides verified specifications, SOIC-8 package details, dual-channel FET-input amplifier functionality, thermal performance data, and validated alternative options for design-in and supply continuity planning.
Technical Context
The TL082IPG4 implements a high-slew-rate JFET-input differential pair with cascode gain stage and Class AB output stage, enabling fast settling (0.48 μs to 0.01%) and low distortion (0.00012% THD+N). Its input stage supports common-mode voltage up to VCC+, eliminating need for level-shifting in single-supply configurations.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, supporting operation across –40°C to +125°C. The device draws 937.5–1125 μA per amplifier and drives capacitive loads up to 300 pF without instability.

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 | Commercial-grade (0°C to 70°C), higher max offset (10 mV), no integrated EMI filters | Cost-sensitive consumer audio or non-critical industrial monitoring | Select when ambient temperature stays below 70°C and EMI immunity is not required |
| OPA2134UA | Lower noise (8 nV/√Hz), lower distortion (0.00008%), but narrower supply range (±4.5 V to ±18 V) | High-end audio preamps and precision instrumentation requiring ultra-low noise | Choose when noise performance dominates over supply flexibility and cost |
Compared with TL082CDR, TL082IPG4 offers extended temperature range and EMI filtering for harsh environments; compared with OPA2134UA, it trades some noise performance for wider supply voltage and higher output drive capability.

The TL082IPG4 belongs to TI's TL08xx FET-input op-amp family, engineered for cost-sensitive yet performance-demanding applications including audio, power conversion, and test equipment where JFET input benefits-low bias current, wide common-mode range, and high slew rate-are essential.
FAQ
What is the operating temperature range of the TL082IPG4?
The TL082IPG4 is specified for operation from –40°C to +125°C, making it suitable for industrial motor drives, solar inverters, and automotive-adjacent test equipment. This extended range is confirmed in Section 5.3 of the TI datasheet and distinguishes it from commercial variants like TL082CDR (0°C to 70°C). The TL082IPG4 maintains its 20 V/μs slew rate and ±1 mV offset voltage across this full range.
Does TL082IPG4 support rail-to-rail input?
The TL082IPG4 supports common-mode input voltage up to VCC+, meaning its input range extends to the positive supply rail-but not to VCC–. The minimum common-mode voltage is (VCC–) + 1.5 V per Section 5.7 of the datasheet. It is not a true rail-to-rail input op-amp, but the inclusion of VCC+ enables simplified single-supply designs without level-shifting resistors on high-side signals.
What package type is used for TL082IPG4?
TL082IPG4 uses an 8-pin SOIC (Small Outline Integrated Circuit) package, also designated as "D" in TI's packaging nomenclature. This surface-mount package has standard 1.27 mm pitch, gull-wing leads, and JEDEC MS-012AC dimensions. It is compatible with automated pick-and-place and reflow soldering processes per IPC-7351B footprint guidelines.
How does TL082IPG4 compare to TL082CP in terms of performance?
TL082IPG4 is the industrial-grade version with –40°C to +125°C operation, 1.5 kV HBM ESD rating, and integrated EMI filters; TL082CP is a through-hole PDIP variant rated only for 0°C to 70°C with no EMI filtering. Both share identical core specs (20 V/μs slew rate, 5.25 MHz GBW), but TL082IPG4 adds ruggedization for demanding environments where TL082CP would be unsuitable.
Can TL082IPG4 drive capacitive loads?
Yes, TL082IPG4 is characterized to safely drive capacitive loads up to 300 pF without oscillation, as stated in Section 5.7. This capability supports direct connection to ADC input capacitors, coaxial cables, or filter networks without requiring isolation resistors. For loads >300 pF, external compensation (e.g., series resistor at output) is recommended per Figure 5-25 in the datasheet.
