Product details
Overview
TLE2081AID from Texas Instruments is a single-channel Excalibur high-speed JFET-input operational amplifier optimized for precision AC-coupled 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 3 mV max input offset voltage at –40°C to +85°C, enabling high-fidelity amplification in oscilloscopes, digital multimeters, and flight control units.
For engineers reviewing the TLE2081AID datasheet, TLE2081AID pinout, TLE2081AID application, or TLE2081AID equivalent, this device serves as a direct upgrade path from TL081/TL071 with doubled bandwidth, extended rail-to-rail dynamic range, and improved noise performance-critical when selecting op-amps for high-speed data acquisition or low-power audio processing stages.
Technical Context
The TLE2081AID uses a JFET-input stage with high-impedance differential pair architecture, delivering 100 MΩ common-mode and 6 TΩ differential input resistance. Its internal compensation ensures stable unity-gain operation with 56° phase margin and 300 kHz full-output-swing bandwidth under 25 pF load.
It operates across ±2.25 V to ±19 V supplies and supports rail-to-rail output swing within 1.5 V of either rail at 20 mA load. Input common-mode range extends to within 1.9 V of negative rail at ±5 V supply and to –11.9 V at ±15 V supply-enabling wide dynamic signal capture in high-voltage sensor interfaces.
Key Specifications

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 |
|---|---|---|---|
| TL081CD | Lower bandwidth (4 MHz), higher 6 mV VIO, no guaranteed –40°C to +85°C operation | Acceptable only in cost-sensitive commercial-grade designs with relaxed speed/accuracy | Select TLE2081AID where 10.6 MHz BW, 3 mV VIO, or extended temperature compliance is required |
| OPA134UA | Higher 8 MHz GBW, lower 0.5 mV VIO, but limited to ±18 V max supply and no –40°C to +85°C grade | Better for audio; unsuitable for industrial environments requiring full temp-range validation | Choose TLE2081AID for guaranteed performance across –40°C to +85°C and ±19 V operation |
Compared with TL081CD and OPA134UA, the TLE2081AID uniquely combines 10.6 MHz bandwidth, 3 mV VIO over full industrial temperature range, and ±19 V supply support-making it the only option qualified for high-reliability, high-dynamic-range applications like flight control and EV charging infrastructure.

FAQ
What is the maximum supply voltage for TLE2081AID?
The TLE2081AID supports a total supply voltage (VCC+ to VCC–) of up to 38 V, allowing operation from ±2.25 V to ±19 V. This enables compatibility with legacy ±15 V systems and newer ±12 V or ±19 V industrial rails without external regulation. Absolute maximum ratings prohibit exceeding ±19 V per supply pin.
Does TLE2081AID have internal frequency compensation?
Yes, the TLE2081AID is internally compensated for unity-gain stability, with a measured phase margin of 56° at unity gain and 25 pF capacitive load. This eliminates the need for external compensation components in standard non-inverting or inverting configurations, simplifying design for high-speed buffer and gain applications.
What is the input offset voltage specification for TLE2081AID over temperature?
The TLE2081AID guarantees a maximum input offset voltage of 3 mV at 25°C and 5 mV over its full operating range of –40°C to +85°C. Its temperature coefficient is specified at 3.2–29 μV/°C, ensuring predictable drift behavior in precision analog circuits such as DMM front-ends and sensor signal conditioners.
Can TLE2081AID drive capacitive loads directly?
The TLE2081AID can safely drive up to 25 pF capacitive loads while maintaining 56° phase margin and stable unity-gain operation. For larger loads (e.g., >50 pF), an external series resistor (typically 20–100 Ω) is recommended at the output to isolate the capacitance and preserve stability-verified in TI's application note SLOA058.
Is TLE2081AID pin-compatible with TL081?
Yes, the TLE2081AID is pin-compatible with TL081 in SOIC-8 (D) and PDIP-8 (P) packages. It shares identical pinout (IN–, IN+, VCC–, OUT, VCC+) and requires no PCB changes-making it a drop-in upgrade that delivers 2× bandwidth, lower offset, and extended supply range without layout modification.
