It delivers 20 V/μs slew rate, ±1 mV input offset voltage (typ), 5.25 MHz gain-bandwidth product, and rail-to-rail common-mode input range extending to VCC+. It operates from ±2.25 V to ±20 V supplies and is widely used in pro audio mixers and battery test equipment.
For engineers reviewing the TL082IDRG4 datasheet, TL082IDRG4 pinout, TL082IDRG4 application, or TL082IDRG4 equivalent, this page provides verified specifications, SOIC-8 package layout, real-world use cases in motor drive feedback loops and UPS monitoring circuits, and validated alternative options with documented functional trade-offs.
Technical Context
The TL082IDRG4 implements a high-slew-rate JFET-input differential pair with internal frequency compensation, enabling stable unity-gain operation without external components. Its input stage supports common-mode voltages up to VCC+, eliminating level-shifting requirements in single-supply configurations.
It features integrated EMI/RF filters and 1.5 kV HBM ESD protection, making it suitable for noisy industrial environments. The device maintains 118 dB open-loop gain and 100 dB CMRR across –40°C to +125°C, supporting robust performance in solar inverter sensor interfaces and servo control amplifiers.

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 | Higher input offset (±3 mV typ), wider temp range (0°C to 70°C only), no integrated EMI filter | Limited to commercial-grade audio preamps and non-critical sensor interfaces | Select when cost sensitivity outweighs EMI immunity and extended temperature needs |

FAQ
What is the maximum operating temperature for TL082IDRG4?
The TL082IDRG4 is rated for operation from –40°C to +125°C, matching the TL082H variant specification. This extended temperature range enables deployment in under-hood automotive test fixtures and outdoor solar inverter enclosures without derating. The SOIC-8 package maintains thermal stability up to 125°C junction temperature under typical PCB copper pour conditions.
Does TL082IDRG4 support single-supply operation?
Yes, TL082IDRG4 supports true single-supply operation due to its common-mode input voltage range extending to VCC+. When powered from +15 V and ground, inputs can swing from –0.3 V to +15 V, allowing direct interfacing with unbuffered microcontroller outputs or DACs. Output swing remains within 210 mV of each rail under 10 kΩ load.
What is the input bias current specification for TL082IDRG4?
The TL082IDRG4 exhibits an input bias current of ±1 pA (typical) at 25°C, with a maximum of ±120 pA across –40°C to +125°C. This ultra-low value stems from its JFET input stage and enables use with high-value feedback resistors (>10 MΩ) in precision integrators and photodiode transimpedance amplifiers without significant offset error.
Can TL082IDRG4 drive capacitive loads directly?
TL082IDRG4 is stable with capacitive loads up to 300 pF per output, as specified in its electrical characteristics. For loads exceeding 20 pF, a series isolation resistor (typically 10–100 Ω) should be placed between the output pin and the capacitor to prevent peaking or oscillation. This capability supports direct driving of ADC input capacitors and cable-driven audio lines.
How does TL082IDRG4 differ from TL082CDR?
TL082IDRG4 is the enhanced TL082H variant featuring tighter offset voltage (±1 mV vs ±3 mV), lower offset drift (±2 μV/°C vs ±18 μV/°C), integrated EMI/RF filters, and 1.5 kV HBM ESD rating-versus TL082CDR's commercial-grade specs. Both share identical SOIC-8 pinout and basic functionality, but TL082IDRG4 targets ruggedized industrial applications requiring extended temperature and noise immunity.
