Product details
Overview
TL082IDRE4 from Texas Instruments is a dual JFET-input operational amplifier optimized for precision AC and DC signal conditioning in industrial and audio systems. It delivers 20 V/μs slew rate, ±1 mV input offset voltage (typ), 5.25 MHz gain-bandwidth product, and operates from ±2.25 V to ±20 V supplies. Its rail-to-rail common-mode input range extending to VCC+ enables high-side sensing in motor drive current feedback loops.
For engineers reviewing the TL082IDRE4 datasheet, TL082IDRE4 pinout, TL082IDRE4 application, or TL082IDRE4 equivalent, this page provides verified specifications, SOIC-8 package layout, dual-channel FET-input op-amp use cases in pro audio mixers and battery test equipment, and validated alternative parts with documented parameter differences.
Technical Context
The TL082IDRE4 integrates two independent high-slew-rate JFET-input amplifiers sharing no internal coupling-ensuring channel separation >100 dB at DC. Its input stage uses matched JFET pairs for ultra-low input bias current (±1 pA typ) and low drift (±2 μV/°C), while the output stage provides short-circuit protection and drives capacitive loads up to 300 pF.
Designed for wide-supply operation (±2.25 V to ±20 V), it maintains stable phase margin (56°) under unity-gain conditions with 20 pF load and exhibits EMI rejection of 53 dB at 1 GHz-critical for noisy industrial environments like solar string inverters and servo drive control modules.

|---|---|---|
| 1 | Output of Amplifier 1 | Delivers buffered, low-impedance output signal; capable of sourcing/sinking ±26 mA. |
| 2 | Inverting Input of Amplifier 1 | Accepts feedback or inverted signal path; high-impedance (6 TΩ || 1 pF) minimizes loading. |
| 3 | Non-inverting Input of Amplifier 1 | Accepts reference or non-inverted signal; common-mode range includes VCC+ for high-side sensing. |
| 4 | Negative Supply (VCC–) | Ground or negative rail connection; supports split or single-supply operation with proper decoupling. |
| 5 | Non-inverting Input of Amplifier 2 | Independent input for second channel; identical electrical characteristics to Pin 3. |
| 6 | Inverting Input of Amplifier 2 | Independent input for second channel; matches Pin 2 performance and noise specs. |

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 (1 kV HBM), no integrated EMI filters | Suitable for cost-sensitive consumer audio where RF immunity is not critical | Select TL082CDR only if full temperature range (–40°C to +125°C) and EMI robustness are not required. |
| OPA2134UA | Lower noise (8 nV/√Hz), higher GBW (8 MHz), ±13 V max supply, no short-circuit protection | Better for high-fidelity audio but incompatible with 40 V total supply or harsh industrial environments | Choose OPA2134UA for studio-grade audio paths; avoid in motor drives or solar inverters requiring ruggedness. |
Compared with TL082CDR and OPA2134UA, TL082IDRE4 uniquely combines 125°C operation, 1.5 kV HBM, integrated EMI filtering, and rail-to-rail common-mode input-making it the only option qualified for industrial-grade solar and motor control designs demanding long-term reliability.

FAQ
What is the maximum supply voltage for TL082IDRE4?
The TL082IDRE4 supports a total supply voltage (VCC+ to VCC–) of up to 40 V, corresponding to ±20 V dual supplies or +40 V/0 V single supply. Absolute maximum ratings specify 42 V for non-NS/PS packages, but TI recommends staying within 40 V for reliable long-term operation per the Recommended Operating Conditions table.
Does TL082IDRE4 have rail-to-rail output swing?
No, TL082IDRE4 does not feature rail-to-rail output. Its output swing is limited to within 115–210 mV of each rail under 10 kΩ load at ±20 V supply. For example, with ±15 V supplies, typical output range is ±13.5 V-not ±15 V-so design margins must account for headroom.
Can TL082IDRE4 drive capacitive loads?
Yes, TL082IDRE4 is specified to drive up to 300 pF capacitive load while maintaining stability. However, for loads exceeding 100 pF, TI recommends adding a small series resistor (e.g., 10–50 Ω) between the output and capacitor to isolate the reactive load and preserve phase margin.
What is the input bias current specification for TL082IDRE4 at 125°C?
At TA = –40°C to +125°C, TL082IDRE4's input bias current is specified at ±5 nA maximum (per amplifier). This is significantly higher than the ±1 pA typical value at 25°C, reflecting JFET leakage increase with temperature-critical for high-impedance sensor interfaces operating at elevated ambient temperatures.
Is TL082IDRE4 pin-compatible with TL082CP?
Yes, TL082IDRE4 and TL082CP share identical SOIC-8 (D) package pinout and basic functionality. However, TL082IDRE4 is the enhanced "H" grade (–40°C to +125°C, 1.5 kV HBM, EMI filters), whereas TL082CP is the commercial-grade "C" version (0°C to +70°C, no EMI filters). Electrical parameters differ-especially offset, drift, and noise-so direct substitution requires validation.
