Product details
Overview
TLE2081AIP from Texas Instruments is a single-channel Excalibur high-speed JFET-input operational amplifier designed for precision AC-coupled signal conditioning in demanding analog front-ends. It delivers 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, ±19 V supply capability, and 3 mV max input offset voltage at 25°C - enabling high-fidelity amplification in oscilloscopes, digital multimeters, and flight control units.
For engineers reviewing the TLE2081AIP datasheet, TLE2081AIP pinout, TLE2081AIP application, or TLE2081AIP equivalent, key selection considerations include its JFET-input architecture for low input bias current (15–175 nA), wide common-mode range (±11.9 V at ±15 V supplies), low 1/f noise (2.77 μVPP, 0.1–10 Hz), and compatibility with legacy TL08x designs while doubling bandwidth.
Technical Context
The TLE2081AIP uses a JFET-input differential pair to achieve ultra-low input bias current and high input impedance (6 TΩ differential, 100 MΩ common-mode), supporting high-source-impedance sensor interfaces without significant DC error. Its internal compensation ensures stable unity-gain operation with 56° phase margin and 300 kHz full-output-swing bandwidth.
It operates across –40°C to +85°C with ±2.25 V to ±19 V dual-supply flexibility, delivering rail-to-rail output swing capability (±14.5 V at ±15 V, 20 mA load) and robust 65 mA short-circuit protection per channel - critical for transient-tolerant industrial measurement systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - supports stable closed-loop gain ≥1 with fast settling for 10-bit+ data acquisition |
| Slew rate | 32 V/μs - enables accurate reproduction of >1 MHz full-scale sine waves without distortion |
| Input offset voltage (max) | 3 mV at 25°C - limits DC error to <0.06% of ±15 V full scale in precision instrumentation |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in battery-powered and industrial power rails |
| Input bias current (typ) | 15 nA - minimizes voltage drop across high-Z sources (e.g., piezoelectric sensors, pH electrodes) |
| Common-mode input range | –11.9 V to +15 V at ±15 V supply - allows direct interface to signals near negative rail in single-supply-derived systems |
| THD+N | 0.0032% at 1 kHz - meets audio-grade linearity requirements for low-power audio processing |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No connection - must remain unconnected to avoid parasitic coupling or latch-up risk |
| 2 | IN– | Inverting input - accepts feedback network for stable closed-loop configurations (e.g., inverting amplifier, active filter) |
| 3 | IN+ | Non-inverting input - used for high-impedance signal routing in buffer, summing, or comparator applications |
| 4 | VCC– | Negative supply rail - requires low-impedance decoupling (e.g., 0.1 μF ceramic) within 1 cm of pin |
| 5 | NC | No connection - electrically isolated; no internal bond wire or circuit node |
| 6 | OUT | Amplifier output - drives loads down to 600 Ω; includes internal short-circuit protection |
| 7 | VCC+ | Positive supply rail - referenced to VCC–; supports symmetrical or asymmetrical dual-supply operation |
| 8 | NC | No connection - floating terminal; no internal function or thermal path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL081CP | Lower bandwidth (4 MHz), higher VIO (15 mV max), no Excalibur process - 3× slower slew rate (13 V/μs) | Limited to lower-frequency instrumentation; unsuitable for >500 kHz signal paths or precision DMMs | Select when cost sensitivity outweighs speed/precision needs and legacy TL08x footprint is mandatory |
| OPA134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz @1kHz), but narrower supply (±18 V max) and no PDIP option | Better for audio and low-noise sensor amps; lacks direct PDIP-8 drop-in compatibility with TLE2081AIP layouts | Choose for ultra-low-noise audio or medical sensor apps where SOIC-8 is acceptable and ±18 V supply suffices |
Compared with TL081CP and OPA134PA, the TLE2081AIP uniquely balances legacy pin compatibility, 10.6 MHz bandwidth, ±19 V operation, and PDIP-8 packaging - making it the only option that upgrades TL08x-based designs without board rework while meeting modern high-speed measurement requirements.

FAQ
What is the maximum supply voltage rating for the TLE2081AIP?
The TLE2081AIP has an absolute maximum supply voltage rating of ±19 V (38 V total across VCC+ and VCC–). Operation beyond this risks permanent damage. Recommended operating range is ±2.25 V to ±19 V, with full specifications guaranteed across that span. This rating enables use in high-dynamic-range applications like AC charging station monitoring where transient overvoltage margins are critical.
Does the TLE2081AIP support single-supply operation?
Yes, the TLE2081AIP supports single-supply operation when biased appropriately - for example, with VCC– grounded and VCC+ at +36 V, or using split-rail virtual ground techniques. Its common-mode input range extends to within 1.9 V of either rail (e.g., –1.9 V to +34.1 V with 0 V/36 V supplies), and output swings to within 1.5 V of each rail under 20 mA load. This makes the TLE2081AIP suitable for portable DMMs and battery-powered oscilloscope modules.
How does the TLE2081AIP compare to the standard TLE2081IP in terms of DC precision?
The TLE2081AIP offers superior DC precision versus the TLE2081IP: its input offset voltage is specified at 3 mV max (vs. 6 mV max for TLE2081IP) at 25°C, and its input offset voltage drift is identical (3.2–29 μV/°C) across temperature. This tighter VIO spec directly improves accuracy in precision measurement circuits such as electricity meters and flight control analog signal chains where baseline error must be minimized.
Is the TLE2081AIP pin-compatible with TL081-based PCBs?
Yes, the TLE2081AIP in PDIP-8 package is fully pin-compatible with TL081, TL071, and TL051 - sharing identical pin 1–8 assignments (NC, IN–, IN+, VCC–, NC, OUT, VCC+, NC). No PCB modification is needed for drop-in replacement, and the TLE2081AIP's doubled bandwidth (10.6 MHz vs. 4 MHz), lower noise, and improved VIO provide immediate performance uplift without redesign effort.
What thermal derating applies to the TLE2081AIP in PDIP-8 package?
The TLE2081AIP in PDIP-8 package has a power dissipation rating of 1000 mW at TA ≤ 25°C, derating linearly at 8.0 mW/°C above 25°C. At 70°C ambient, usable power drops to 640 mW; at 85°C, it falls to 344 mW. This derating must be applied when calculating junction temperature rise - especially in enclosed industrial enclosures or high-density layouts where airflow is restricted.
