Product details
Overview
TLE2082AMP from Texas Instruments is a dual high-speed JFET-input operational amplifier designed for precision AC and DC signal conditioning in demanding industrial and test equipment. It delivers 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, ±19 V supply capability, and 85 dB common-mode rejection - enabling high-fidelity amplification in oscilloscopes, data acquisition systems, and electricity meters.
For engineers reviewing the TLE2082AMP datasheet, TLE2082AMP pinout, TLE2082AMP application, or TLE2082AMP equivalent, this device serves as a direct upgrade path from TL072/TL082 with doubled bandwidth, extended rail-to-rail dynamic range, and verified performance across –40°C to 85°C operating temperatures in SOIC-8 packaging.
Technical Context
The TLE2082AMP belongs to the Excalibur high-voltage op-amp family, featuring JFET input stages that deliver ultra-low input bias current (≤175 pA) and high input impedance (6 TΩ differential). Its internal compensation ensures stable unity-gain operation with 56° phase margin at ±5 V and 57° at ±15 V supplies.
It supports dual-channel independent operation with 120 dB crosstalk attenuation, enabling simultaneous high-speed signal paths without inter-channel interference. The device maintains low THD+N (0.0032%) and low noise (7 nV/√Hz at 1 kHz, ±15 V), making it suitable for low-distortion analog front-ends in portable instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 up to audio and low-RF frequencies without external compensation. |
| Slew rate | 32 V/μs - supports fast transient response for 2 V step signals settling to 1 mV in 1.5 μs at ±15 V supply. |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in high-voltage sensor interfaces and power stage monitoring. |
| Input offset voltage (max) | 4 mV at 25°C (TLE2082AC variant) - ensures <1 LSB error in 12-bit systems with ±10 V full-scale input. |
| Common-mode rejection | 85 dB - rejects >99.9% of shared noise on differential inputs in noisy industrial environments. |
| THD + N | 0.0032% at 1 kHz - preserves signal fidelity in precision audio and metrology-grade measurement chains. |
| Crosstalk attenuation | 120 dB - prevents coupling between channels in dual-signal-path designs like stereo analyzers or dual-axis sensors. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6.0 mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |

| VCC– | Negative Power Supply | Reference return for both amplifiers; must be decoupled locally to minimize PSRR degradation. |
| 2IN+ | Non-inverting Input, Channel 2 | Independent second input channel; electrically isolated from Channel 1 except via shared supply rails. |
| 2IN– | Inverting Input, Channel 2 | Second differential input; supports fully independent gain/feedback design per channel. |
| 2OUT | Output, Channel 2 | Second independent output; matches Channel 1 performance including slew rate and output drive. |
| VCC+ | Positive Power Supply | Primary positive rail connection; requires low-ESR ceramic bypass capacitor near pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Direct TL072/TL082 upgrade | Pins 1–8 match TL072 footprint and function, enabling drop-in replacement without PCB redesign. |

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 |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher input offset (10 mV max), no A-grade option; same SOIC-8 pinout. | Limited to lower-speed signal chains where 10.6 MHz is unnecessary; not suitable for >1 MSPS data acquisition. | Select when cost sensitivity outweighs speed/precision needs and existing TL072 layout can be reused. |
| OPA2134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but narrower supply range (±18 V max) and no –40°C to 85°C industrial grade. | Better for audio-grade low-noise apps; lacks extended temperature validation for metering or drive modules. | Choose for premium audio or lab-grade instrumentation where thermal drift and noise dominate over ruggedness. |
Compared with TL072CDR, TLE2082AMP doubles bandwidth and halves input offset while maintaining pin compatibility; versus OPA2134PA, it trades minor noise penalty for guaranteed industrial temperature operation and higher supply tolerance.

FAQ
What is the maximum supply voltage rating for the TLE2082AMP?
The TLE2082AMP supports a total supply voltage (VCC+ – VCC–) up to 38 V, with individual rails rated from ±2.25 V to ±19 V. This allows operation at ±15 V standard industrial rails and extends to ±19 V for enhanced dynamic range in high-voltage sensor interfaces - confirmed in Section 6.1 Absolute Maximum Ratings of the TI SLOS182C datasheet.
Is the TLE2082AMP pin-compatible with the TL072?
Yes, the TLE2082AMP uses the same SOIC-8 (D) package and identical pin configuration as the TL072, including 1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, and VCC+. This enables direct drop-in replacement in existing TL072 layouts without PCB modification - explicitly stated in the "Direct upgrades to TL05x, TL07x, and TL08x" feature list.
What is the typical input bias current of the TLE2082AMP at 25°C?
The typical input bias current of the TLE2082AMP is 15 pA at 25°C, with a maximum of 175 pA across the full –40°C to 85°C operating range. This ultra-low value is enabled by its JFET input stage and ensures minimal loading error in high-impedance circuits such as photodiode transimpedance amplifiers or precision voltage references - per Table 6.12 Electrical Characteristics.
Does the TLE2082AMP require external compensation for unity-gain stability?
No, the TLE2082AMP is internally compensated for unity-gain stability, delivering 56° phase margin at ±5 V and 57° at ±15 V supplies with 25 pF capacitive load. This eliminates the need for external compensation components in standard gain ≥1 configurations - verified in Sections 6.5 and 6.13 Operating Characteristics.
What is the common-mode input voltage range for the TLE2082AMP at ±15 V supply?
At ±15 V supply, the TLE2082AMP supports a common-mode input voltage range of –10.9 V to +15 V (relative to ground), as specified in Table 6.6 Electrical Characteristics. This rail-to-rail input capability relative to the negative rail enables accurate sensing of signals near VCC– in single-supply-derived configurations.
