Product details
Overview
TLE2082IP from Texas Instruments is a dual high-speed JFET-input operational amplifier in an 8-pin PDIP package, delivering 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and ±19 V supply capability. It serves as a direct upgrade to TL072/TL082 in precision AC-coupled signal conditioning paths for oscilloscopes, data acquisition systems, and industrial metering.
For engineers reviewing the TLE2082IP datasheet, TLE2082IP pinout, TLE2082IP application, or TLE2082IP equivalent, key selection criteria include its 4 mV max input offset voltage (at –40°C to 85°C), low 28 nV/√Hz input voltage noise at 1 kHz, and validated crosstalk attenuation of 120 dB-critical for dual-channel integrity in high-fidelity analog front-ends.
Technical Context
The TLE2082IP uses a JFET-input stage with matched P-channel input transistors, enabling high input impedance (>100 MΩ common-mode, >6 TΩ differential) and low input bias current (≤175 nA). 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, supporting rail-to-rail output swing within 1.5 V of rails at 20 mA load. The device maintains DC precision (input offset drift ≤25 μV/°C) while delivering AC performance suitable for 10-bit to 12-bit data acquisition sampling up to 300 kHz full-swing bandwidth.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - supports stable closed-loop gain ≥1 with ≤0.1% gain error up to 100 kHz in non-inverting configurations |
| Slew rate | 32 V/μs - enables full-scale 10 Vpp output transitions in ≤0.31 μs, critical for pulse fidelity in DMM and oscilloscope front-ends |
| Input offset voltage (max) | 7 mV over –40°C to 85°C - ensures ≤0.07% initial gain error in 100× instrumentation amplifier topologies |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic range in AC charging station voltage sensing and flight control analog I/O |
| Crosstalk attenuation | 120 dB - prevents coupling between channels in dual-sensor interfaces like differential pressure or multi-phase motor current monitoring |
| Input voltage noise | 28 nV/√Hz at 1 kHz - limits RMS noise to <1.8 μV in 10 kHz bandwidth, suitable for 16-bit-equivalent resolution in low-frequency sensor amplification |
| Common-mode input range | –10.9 V to +15 V at ±15 V supplies - allows direct interfacing to ±10 V industrial sensors without level-shifting circuitry |

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 |
|---|---|---|---|
| TL082IP | Lower 3 MHz bandwidth, 13 V/μs slew rate, 15 mV max VIO at 85°C, no crosstalk spec | Limited to ≤100 kHz small-signal applications; unsuitable for fast settling or high-resolution DMMs | Select TL082IP only for cost-sensitive legacy designs where bandwidth and noise are not critical |
| OPA2134PA | Higher 8 nV/√Hz noise, 20 V/μs slew rate, ±18 V max supply, SO-8 only (no PDIP) | Better audio THD+N but lower speed; requires PCB redesign for surface-mount assembly | Choose OPA2134PA for low-noise audio or medical sensor apps; avoid when PDIP or >30 V/μs is required |

FAQ
What is the maximum supply voltage for the TLE2082IP?
The TLE2082IP supports a total supply voltage (VCC+ to VCC–) of up to 38 V, corresponding to ±19 V operation. This is confirmed in Section 6.1 Absolute Maximum Ratings of the TI datasheet SLOS182C, where VS = (V+) − (V−) is rated at 38 V. Operation beyond this risks permanent damage, and recommended conditions limit continuous use to ±19 V.
Does the TLE2082IP have pin-to-pin compatibility with the TL082IP?
Yes, the TLE2082IP is pin-to-pin compatible with the TL082IP in the PDIP-8 package. Pin functions match exactly: pins 1–8 correspond to 1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, and VCC+. This is explicitly stated in the "Direct upgrades to TL05x, TL07x, and TL08x" feature list and verified in Figure 5-2 and Table 5-2 of the datasheet.
What is the input offset voltage specification for the TLE2082IP over temperature?
The TLE2082IP (I-suffix, –40°C to +85°C) has a maximum input offset voltage of 7 mV across its full operating temperature range, per Table 4-2 and Section 6.12 of the datasheet. At 25°C, typical VIO is 0.65 mV for the A-grade variant (TLE2082AIP) and 0.9 mV for standard grade (TLE2082IP).
Can the TLE2082IP drive a 600 Ω load effectively?
Yes, the TLE2082IP delivers 91 dB large-signal open-loop gain into 600 Ω loads at ±5 V supplies (Section 6.4), and maintains >80 dB gain even at ±15 V. Its output stage sustains ±65 mA short-circuit current, enabling robust 10 Vpp drive into 600 Ω with <0.1% THD+N at 1 kHz-validated in Section 6.5's THD+N and AVD specifications.
Is the TLE2082IP suitable for use in flight control units?
Yes, the TLE2082IP is qualified for –40°C to +85°C operation (I-suffix), features JFET-input ruggedness against ESD and fast transients, and provides 120 dB crosstalk attenuation-key for redundant dual-channel analog I/O in flight control units. Its 10.6 MHz bandwidth and 32 V/μs slew rate meet DO-160 transient immunity and signal fidelity requirements for sensor conditioning.
