Product details
Overview
TLE2082IDG4 from Texas Instruments is a dual high-speed JFET-input operational amplifier with 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and ±19 V supply capability. It delivers low input offset voltage (7 mV max at –40°C to 85°C), low noise (7 nV/√Hz at 1 kHz), and high CMRR (85 dB), enabling precision signal conditioning in high-voltage, wide-dynamic-range analog front-ends such as oscilloscope vertical amplifiers and AC drive current sensing.
For engineers reviewing the TLE2082IDG4 datasheet, TLE2082IDG4 pinout, TLE2082IDG4 application, or TLE2082IDG4 equivalent, key selection criteria include its dual-channel SOIC-8 package, –40°C to 85°C industrial temperature grade, direct upgrade path from TL082/TL072, and verified performance under ±15 V operation with 300 kHz full-swing bandwidth.
Technical Context
The TLE2082IDG4 uses a JFET-input stage for ultra-low input bias current (≤175 nA) and high input impedance (≥100 MΩ common-mode, ≥6 TΩ differential), supporting high-impedance sensor interfacing without loading. Its Excalibur process enables simultaneous DC precision (low VIO, low αVIO) and AC performance (10.6 MHz B1, 56° phase margin).
It operates across ±2.25 V to ±19 V supplies, delivering rail-to-rail compatible output swing (±14.5 V at 20 mA load with ±15 V supplies) and maintaining stability with capacitive loads up to 25 pF-critical for driving coaxial cables or ADC input buffers in data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - supports stable closed-loop gain ≥1 with ≤100 ns settling to 1 mV for 2 V step |
| Slew rate | 32 V/μs - enables clean reproduction of >1 MHz full-scale sine waves without slewing distortion |
| Supply voltage range | ±2.25 V to ±19 V - accommodates industrial ±15 V rails and extended headroom for overvoltage transients |
| Input offset voltage | 7 mV max (–40°C to 85°C) - ensures ≤0.05% gain error in 10 V full-scale instrumentation amplifiers |
| CMRR | 85 dB - rejects >17,780:1 common-mode interference in differential sensor measurements |
| Input noise voltage | 7 nV/√Hz @ 1 kHz - preserves SNR in low-level signal chains (e.g., piezoelectric sensor interfaces) |
| Crosstalk attenuation | 120 dB - prevents inter-channel coupling in dual-channel simultaneous sampling circuits |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6.0 mm body, 1.27 mm lead pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Lower bandwidth (3 MHz), higher VIO (15 mV max), no Excalibur process | Not suitable for >200 kHz signal paths or low-noise precision designs | Select when cost sensitivity outweighs bandwidth/noise requirements and existing TL082 layout is fixed |
| OPA2134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but 8 MHz bandwidth and ±18 V max supply | Better for audio-grade applications; insufficient for 10+ Vpp fast transient capture | Prefer for battery-powered portable DMMs where ultra-low distortion matters more than slew rate |
Compared with TL082CDR and OPA2134PA, the TLE2082IDG4 uniquely balances 10.6 MHz bandwidth, 32 V/μs slew rate, and ±19 V supply in an industrial-grade SOIC-8-making it optimal for high-fidelity, high-voltage analog acquisition where both speed and robustness are mandatory.

FAQ
What is the maximum supply voltage for the TLE2082IDG4?
The TLE2082IDG4 supports a total supply voltage (VCC+ – VCC–) up to 38 V, allowing operation from ±2.25 V to ±19 V. At ±15 V supplies, it delivers ±14.5 V output swing into 20 mA loads-verified in TI's SLOS182C datasheet Section 6.14. This makes the TLE2082IDG4 suitable for industrial systems requiring headroom beyond standard ±15 V rails.
Does the TLE2082IDG4 have pin compatibility with the TL082?
Yes, the TLE2082IDG4 is pin-compatible with the TL082 in SOIC-8 (D) and PDIP-8 (P) packages. Pin functions match exactly: 1OUT/1IN–/1IN+/VCC–/2IN+/2IN–/2OUT/VCC+. This enables direct drop-in replacement without PCB changes-confirmed in TI's TLE2082 pin configuration diagram (Figure 5-2) and "Direct upgrades to TL05x, TL07x, and TL08x" feature list.
What is the input offset voltage specification for the TLE2082IDG4 over temperature?
The TLE2082IDG4 has a maximum input offset voltage of 7 mV across the full industrial temperature range (–40°C to +85°C), per TI's SLOS182C datasheet Table 4-2 and Section 6.12. At 25°C, typical VIO is 0.65 mV for the 'I' grade. This tight DC spec supports precision applications like electricity metering and flight control signal conditioning where offset drift directly impacts measurement accuracy.
Can the TLE2082IDG4 drive capacitive loads?
Yes, the TLE2082IDG4 is stable driving capacitive loads up to 25 pF, as validated by its 56° phase margin at unity gain with 25 pF load (Section 6.5). This enables direct connection to coaxial cables, ADC input capacitors, or long PCB traces without external isolation resistors-critical for oscilloscope vertical amplifiers and high-speed data acquisition front-ends using the TLE2082IDG4.
What is the slew rate of the TLE2082IDG4 and how does it impact signal fidelity?
The TLE2082IDG4 has a guaranteed minimum slew rate of 32 V/μs (typical), enabling distortion-free amplification of 1 MHz full-scale sine waves at ±10 V output. This exceeds TL082's 13 V/μs by >2.4×, preserving edge integrity in pulse-width modulated motor control feedback and fast transient capture in digital storage oscilloscopes using the TLE2082IDG4.
