Product details
Overview
TLE2082ID from Texas Instruments is a dual high-speed JFET-input operational amplifier designed for precision AC and DC signal conditioning in industrial and test equipment. It delivers 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, ±19 V supply capability, and 7 mV maximum input offset voltage at –40°C to 85°C, enabling use in oscilloscope front-ends and high-speed data acquisition systems.
For engineers reviewing the TLE2082ID datasheet, TLE2082ID pinout, TLE2082ID application, or TLE2082ID equivalent, this page provides verified electrical specifications, SOIC-8 package terminal mapping, real-world implementation context for dual-channel analog signal paths, and validated alternative options for design continuity.
Technical Context
The TLE2082ID uses JFET-input stages to achieve high input impedance (>100 MΩ common-mode, >6 TΩ differential), low input bias current (≤175 nA), and low noise (7 nV/√Hz at 1 kHz with ±15 V supplies). Its internal compensation ensures stable unity-gain operation with ≥56° phase margin into 2 kΩ loads and 25 pF capacitive loads.
It operates across ±2.25 V to ±19 V supplies and supports rail-to-rail output swing within 1.5 V of rails at 20 mA load. The device features crosstalk attenuation of 120 dB between channels, confirming true dual-amplifier independence without inter-channel coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable amplification of signals up to ~10 MHz without external compensation |
| Slew rate | 32 V/μs - supports clean reproduction of fast 2-V step signals with ≤0.4 μs settling to 1 mV |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic range in high-voltage sensor interfaces and power stage monitoring |
| Input offset voltage (max) | 7 mV at –40°C to 85°C - defines worst-case DC error in precision gain stages without trimming |
| Crosstalk attenuation | 120 dB - ensures channel isolation critical for dual-signal processing in DMMs and digitizers |
| Common-mode input range | –10.9 V to +15 V at ±15 V supplies - allows direct interfacing with bipolar sensors referenced to mid-supply |
| Output voltage swing | ±11.5 V at 20 mA load - delivers full-scale analog output into moderate-impedance loads |

| 1IN– | Input | Inverting input for Channel 1 - high-impedance JFET node; requires matched trace routing for noise immunity |
| 1IN+ | Input | Non-inverting input for Channel 1 - accepts DC- or AC-coupled signals up to ±10.9 V common-mode |
| VCC– | Power supply | Negative supply rail - must be decoupled locally with 0.1 μF ceramic capacitor |

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 | Lower 3 MHz bandwidth, higher 15 mV VIO, no guaranteed 120 dB crosstalk | Acceptable for <500 kHz general-purpose amplification but insufficient for oscilloscope front-ends | Select when cost sensitivity outweighs bandwidth and precision requirements |
| OPA2134PA | Higher 8 MHz bandwidth, lower 0.5 mV VIO, FET input, but only ±18 V max supply | Better DC accuracy and noise for audio and sensor apps; lacks ±19 V headroom for industrial HV sensing | Choose for ultra-low-offset, low-noise designs where ±18 V rails suffice |
Compared with TL082CDR, TLE2082ID delivers more than 3× higher bandwidth and half the input offset voltage; versus OPA2134PA, it offers higher supply tolerance and proven crosstalk performance in dual-channel instrumentation, though with slightly higher noise floor.

FAQ
What is the maximum supply voltage for TLE2082ID?
The TLE2082ID supports a total supply voltage of up to 38 V, corresponding to ±19 V operation. This rating is confirmed in the Absolute Maximum Ratings table and enables direct use in high-voltage industrial sensor interfaces without level-shifting circuitry. Exceeding ±19 V risks permanent damage per TI's datasheet specification.
Does TLE2082ID support rail-to-rail output swing?
No, TLE2082ID does not provide rail-to-rail output. At ±15 V supplies and 20 mA load, its output swings to ±11.5 V - a 3.5 V headroom from each rail. This limitation is inherent to its JFET-output stage architecture and is documented in the VOM+/VOM– specifications under Recommended Operating Conditions.
Is TLE2082ID pin-compatible with TL082?
Yes, TLE2082ID is pin-compatible with TL082 in SOIC-8 (D) and PDIP-8 (P) packages. Pin functions match exactly: Pins 1/7 = outputs, 2/6 = inverting inputs, 3/5 = non-inverting inputs, 4 = VCC–, 8 = VCC+. This compatibility is explicitly stated in TI's "Direct upgrades" feature list and verified in the Pin Configuration tables.
What is the input bias current specification for TLE2082ID?
The TLE2082ID has a maximum input bias current of 175 nA at 25°C and full operating temperature range (–40°C to 85°C), as specified in Section 6.14 of the datasheet. This low value stems from its JFET-input architecture and makes it suitable for high-impedance source applications such as photodiode transimpedance stages or piezoelectric sensor buffers.
Can TLE2082ID operate from a single supply?
Yes, TLE2082ID can operate from a single supply, provided the input common-mode and output swing ranges remain within specification. For example, with VCC+ = +38 V and VCC– = 0 V, the input common-mode range is 0 V to +27.1 V (per VICR spec at ±19 V equivalent), and output swing reaches up to +25.5 V. Designers must ensure proper biasing and avoid violating absolute maximum ratings.
