Product details
Overview
TLE2081IDR from Texas Instruments is a single high-speed JFET-input operational amplifier in SOIC-8 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 TL081/TL071 in precision AC-coupled signal conditioning paths for oscilloscopes, digital multimeters, and high-speed data acquisition front-ends.
For engineers reviewing the TLE2081IDR datasheet, TLE2081IDR pinout, TLE2081IDR application, or TLE2081IDR equivalent, key selection criteria include its 6 mV max input offset voltage at –40°C to 85°C, low 28 nV/√Hz input voltage noise at 1 kHz (±5 V), and validated performance in ±15 V high-dynamic-range analog stages with 300 kHz full-output-swing bandwidth.
Technical Context
The TLE2081IDR uses a JFET-input differential pair with high-impedance, low-noise architecture optimized for wide supply operation (±2.25 V to ±19 V) and fast settling (0.4 μs to 1 mV on a 10 V step). Its internal compensation ensures stable unity-gain operation with ≥56° phase margin into 2 kΩ loads and 25 pF capacitive loads.
It achieves DC precision via laser-trimmed input offset voltage and supports rail-to-rail output swing within 1.5 V of each supply at ±20 mA load, while maintaining 85 dB common-mode rejection and 99 dB supply-voltage rejection across temperature.
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 |
|---|---|---|---|
| TL081CDR | Lower 4 MHz bandwidth, 13 V/μs slew rate, 15 mV max VIO at 85°C, no Excalibur process | Acceptable for <500 kHz signal paths where cost is primary; not suitable for 10 MHz scope front-ends | Select when legacy compatibility and lowest BOM cost outweigh speed/noise requirements |
| OPA1611AIDR | Higher 45 MHz bandwidth, 27 V/μs slew rate, 125 μV max VIO, bipolar input, lower 1.1 nV/√Hz noise | Better for ultra-low-noise audio and precision instrumentation; higher quiescent current (3.6 mA vs 2.9 mA) | Select when sub-2 nV/√Hz noise and >20 MHz bandwidth justify higher power and cost |
Compared with TL081CDR, TLE2081IDR delivers twice the bandwidth and half the input offset voltage at identical SOIC-8 footprint; versus OPA1611AIDR, it trades 4× lower noise for 4× lower cost and proven robustness in high-voltage industrial transients.

FAQ
What is the maximum operating temperature range for the TLE2081IDR?
The TLE2081IDR is rated for operation from –40°C to +85°C ambient temperature, matching the I-suffix industrial grade specification. This range is validated across all electrical parameters including input offset voltage, slew rate, and output drive capability, making it suitable for deployment in industrial control cabinets and outdoor EV charging infrastructure.
Does the TLE2081IDR require external compensation for unity-gain stability?
No, the TLE2081IDR is internally compensated for unity-gain stability with ≥56° phase margin into 2 kΩ loads and 25 pF capacitive loads. No external compensation components are needed for standard non-inverting or inverting configurations with gain ≥1, simplifying layout and reducing bill-of-materials count compared to decompensated op-amps.
Can the TLE2081IDR drive a 600 Ω load at full output swing?
Yes, the TLE2081IDR delivers ±11.5 V output swing into a 20 mA load (equivalent to 575 Ω at ±11.5 V), exceeding the 600 Ω requirement. At ±15 V supplies, it maintains >23 VPP linear output range into 600 Ω, verified per datasheet Section 6.6 VOM± specifications and Figure 6-12 load regulation curves.
How does the input offset voltage of the TLE2081IDR compare to the TL081?
The TLE2081IDR has a maximum input offset voltage of 6 mV over –40°C to +85°C, versus 15 mV for the TL081CDR at the same temperature range. This 2.5× improvement reduces baseline error in DC-coupled sensor interfaces and improves accuracy in precision integrators and active filters using the TLE2081IDR.
Is the TLE2081IDR pin-compatible with the TL081CDR in SOIC-8 packages?
Yes, the TLE2081IDR uses identical SOIC-8 pinout (D package) and footprint as the TL081CDR, with Pins 1, 5, and 8 designated as no-connect and functionally mapped to IN– (2), IN+ (3), V– (4), OUT (6), and V+ (7). This enables drop-in replacement without PCB modification in existing TL081 designs.
