Product details
Overview
TLE2082ACP from Texas Instruments is a dual high-speed JFET-input operational amplifier in an 8-pin PDIP 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 TL072/TL082 in precision AC-coupled signal conditioning paths for oscilloscopes, data acquisition systems, and industrial metering.
For engineers reviewing the TLE2082ACP datasheet, TLE2082ACP pinout, TLE2082ACP application, or TLE2082ACP equivalent, this device is selected for high-voltage dynamic range, low input bias current (15–175 nA), and stable operation with capacitive loads up to 25 pF-critical for fast-settling analog front-ends in test equipment and energy measurement.
Technical Context
The TLE2082ACP uses a JFET-input stage enabling ultra-low input bias current and high input impedance (100 MΩ common-mode, 6 TΩ differential), supporting high-source-impedance sensor interfaces without significant DC error. Its Excalibur process delivers improved AC performance over legacy TL08x series while maintaining pin compatibility with industry-standard dual op-amp footprints.
It features internal frequency compensation optimized for unity-gain stability with 56°–57° phase margin and supports rail-to-rail output swing within ±1.5 V of rails at 20 mA load. The device operates across 0°C to 70°C (C-suffix) and handles ±2.25 V to ±19 V supplies, making it suitable for wide-dynamic-range instrumentation amplifiers and active filter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 operation up to audio and low-MHz signal frequencies |
| Slew rate | 32 V/μs - supports clean reproduction of fast transients in oscilloscope vertical amplifiers and pulse conditioning |
| Supply voltage range | ±2.25 V to ±19 V - accommodates high-dynamic-range signal chains in electricity meters and AC drive monitoring |
| Input offset voltage (max) | 6 mV at 25°C - ensures ≤0.1% gain error in 10 V full-scale precision amplification stages |
| Input bias current (max) | 175 nA - minimizes voltage drop across high-Z source impedances (e.g., piezoelectric sensors, photodiode TIA feedback) |
| Common-mode input range | –10.9 V to +15 V at ±15 V supply - allows direct interfacing to bipolar signals in industrial control I/O modules |
| Output short-circuit current | ±65 mA - provides robust drive capability into low-impedance loads like relay drivers or ADC reference buffers |
Pinout & Package
Package: PDIP-8 (Plastic Dual In-line Package), 9.81 mm × 9.43 mm, through-hole mountable with standard 0.3-inch DIP footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output | Amplifier Channel 1 output - drives external load or next-stage input with ±14.5 V swing at 20 mA |
| 1IN– | Input | Inverting input, Channel 1 - accepts feedback network for configured gain or filtering |
| 1IN+ | Input | Non-inverting input, Channel 1 - connects to signal source or reference in follower/buffer configurations |
| VCC– | Power supply | Negative supply rail - must be decoupled locally to minimize noise coupling into high-impedance inputs |
| 2IN+ | Input | Non-inverting input, Channel 2 - independent channel enables dual-path signal processing without cross-talk (120 dB attenuation) |
| 2IN– | Input | Inverting input, Channel 2 - supports separate gain configuration per channel in multi-channel DAQ front-ends |
| 2OUT | Output | Amplifier Channel 2 output - electrically isolated from Channel 1; shares same supply pins |
| VCC+ | Power supply | Positive supply rail - requires local 0.1 μF ceramic decoupling to maintain stability at high frequencies |
Key Features

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 |
|---|---|---|---|
| TL082CP | Lower bandwidth (4 MHz), slower slew rate (13 V/μs), higher input offset (15 mV max), same PDIP-8 package | Acceptable for <100 kHz signal paths but insufficient for fast-settling or wideband applications like oscilloscopes | Select when cost sensitivity outweighs speed/precision requirements and existing designs already use TL082 footprint |
| OPA2134PA | Higher precision (500 μV max VIO), lower noise (8 nV/√Hz), wider supply (±18 V), SO-8 only - no PDIP option | Better suited for audio and low-noise instrumentation; lacks guaranteed 25 pF capacitive load stability | Choose for ultra-low-noise, low-distortion applications where PCB redesign for SOIC is acceptable and ±18 V supply suffices |
Compared with TL082CP and OPA2134PA, the TLE2082ACP uniquely balances high speed (10.6 MHz), high supply tolerance (±19 V), and PDIP-8 compatibility - making it the optimal choice for upgrading legacy test equipment and industrial metering hardware without layout changes.

FAQ
What is the maximum operating supply voltage for the TLE2082ACP?
The TLE2082ACP supports a total supply voltage of up to 38 V, corresponding to ±19 V on VCC+ and VCC– pins. This allows operation with ±15 V rails plus 4 V of margin for transient spikes, making it suitable for demanding industrial environments where supply regulation may vary.
Does the TLE2082ACP require external compensation for unity-gain stability?
No, the TLE2082ACP is internally compensated for unity-gain stability and maintains ≥56° phase margin with up to 25 pF capacitive load. External compensation is unnecessary for standard gain ≥1 configurations, simplifying design in ADC driver and buffer applications.
Can the TLE2082ACP replace TL082 in existing designs without modifications?
Yes - the TLE2082ACP uses identical PDIP-8 pinout and electrical behavior as TL082, with enhanced bandwidth, slew rate, and supply range. No PCB or schematic changes are required for drop-in replacement in most TL082-based circuits, provided thermal and layout constraints remain within spec.
What is the typical input bias current of the TLE2082ACP at room temperature?
The typical input bias current of the TLE2082ACP is 15 nA at 25°C, with a maximum of 175 nA across the 0°C to 70°C operating range. This JFET-input characteristic enables high-impedance sensor interfacing without significant DC error or settling delay.
How does the TLE2082ACP perform in low-noise applications compared to TL072?
The TLE2082ACP delivers 28 nV/√Hz input voltage noise at 1 kHz - identical to TL072 - but offers superior large-signal performance: 32 V/μs slew rate vs. 13 V/μs and 10.6 MHz bandwidth vs. 3 MHz. Its noise floor remains unchanged while enabling faster, cleaner signal processing in scope and DAQ front-ends.
