Product details
Overview
TLE2082AIDR from Texas Instruments is a dual high-speed JFET-input operational amplifier with 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and ±19 V supply capability. It delivers low input offset voltage (max 4 mV at 25°C), low noise (7 nV/√Hz at 1 kHz, ±15 V), and operates across –40°C to 85°C. It serves as a direct upgrade to TL082 and TL072 in precision analog front-ends for test equipment and industrial signal conditioning.
For engineers reviewing the TLE2082AIDR datasheet, TLE2082AIDR pinout, TLE2082AIDR application, or TLE2082AIDR equivalent, key selection criteria include its dual-channel JFET architecture, rail-to-rail output swing limitations (±14.5 V at 20 mA load), crosstalk attenuation of 120 dB, and SOIC-8 package compatibility with legacy TL08x footprints.
Technical Context
The TLE2082AIDR implements a high-voltage JFET-input stage enabling wide common-mode range (–10.9 V to +15 V at ±15 V supplies) and low input bias current (≤175 nA). Its internal compensation ensures stable unity-gain operation with 56° phase margin and 300 kHz full-output-swing bandwidth.
It supports dual independent amplifiers in one SOIC-8 package, with no internal coupling beyond specified 120 dB crosstalk attenuation. The device meets Excalibur process performance targets for AC-coupled high-speed data acquisition and DC-stable sensor interfacing without external trimming.
Key Specifications

| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop operation up to ~1 MHz with gain ≥ 10. |
| Slew rate | 32 V/μs - supports 10 Vpp signals up to ~300 kHz without slewing distortion. |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic range in industrial power rails. |
| Input offset voltage (max) | 4 mV at 25°C - allows ≤0.1% error in 4-V full-scale precision measurement paths. |
| Crosstalk attenuation | 120 dB - ensures channel isolation sufficient for dual-channel simultaneous sampling. |
| Input noise voltage | 7 nV/√Hz at 1 kHz (±15 V) - suitable for low-level sensor amplification with <1 μVpp integrated noise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Lower bandwidth (4 MHz), higher VIO (15 mV max), 13 V/μs slew rate, same SOIC-8 package. | Limited to lower-speed signal chains; insufficient for >1 MHz acquisition or fast transient capture. | Select when cost sensitivity outweighs speed/noise requirements and ±15 V supply is sufficient. |
| OPA2134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but narrower supply (±18 V) and lower slew rate (20 V/μs). | Better for audio and ultra-low-distortion DC-coupled paths; less suitable for high-slew industrial transients. | Prefer for battery-powered portable instruments where low THD+N (0.00008%) and rail compatibility matter more than speed. |
Compared with TL082CDR and OPA2134PA, the TLE2082AIDR uniquely balances high slew rate, wide supply, and legacy pin compatibility-making it optimal for upgrading existing TL082-based industrial test and measurement hardware without PCB redesign.

FAQ
What is the maximum supply voltage for TLE2082AIDR?
The TLE2082AIDR supports a total supply voltage (VCC+ – VCC–) up to 38 V, with individual rails rated from ±2.25 V to ±19 V. Operation at ±19 V enables full output swing of ±14.5 V into 20 mA loads, critical for high-dynamic-range industrial signal chains. Absolute maximum ratings must not be exceeded to avoid permanent damage.
Does TLE2082AIDR support rail-to-rail output?
No, the TLE2082AIDR does not provide rail-to-rail output. At ±15 V supplies and 20 mA load, its output swings from –14.5 V to +14.5 V - a 1.0 V saturation margin per rail. This limitation is inherent to its JFET-input, bipolar-output stage architecture and must be accounted for in headroom budgeting for precision applications.
How does TLE2082AIDR compare to TL082 in terms of noise performance?
The TLE2082AIDR achieves 7 nV/√Hz input voltage noise at 1 kHz under ±15 V supplies - approximately half the 13–18 nV/√Hz typical of TL082. Its 2.77 μVPP (0.1–10 Hz) low-frequency noise also improves upon TL082's ~5 μVPP, making TLE2082AIDR better suited for DC-stable, low-drift applications like digital multimeters and precision sensor interfaces.
Is TLE2082AIDR pin-compatible with TL082CDR?
Yes, the TLE2082AIDR uses the standard SOIC-8 (D) package with identical pinout to TL082CDR: Pin 1 = OUT A, Pin 2 = IN– A, Pin 3 = IN+ A, Pin 4 = V–, Pin 5 = IN+ B, Pin 6 = IN– B, Pin 7 = OUT B, Pin 8 = V+. This allows direct physical replacement in existing TL082 layouts without PCB modification.
What is the crosstalk specification for TLE2082AIDR?
The TLE2082AIDR specifies 120 dB crosstalk attenuation between its two amplifier channels at 25°C. This means a 1 V signal on Channel 1 produces only 1 μV coupled onto Channel 2's output - sufficient for simultaneous sampling in dual-channel data acquisition systems where inter-channel interference must remain below ADC LSB thresholds.
