Product details
Overview
TLE2082CP 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 TL082 and TL072 in precision AC-coupled signal conditioning, oscilloscope front-ends, and high-speed data acquisition channels.
For engineers reviewing the TLE2082CP datasheet, TLE2082CP pinout, TLE2082CP application, or TLE2082CP equivalent, key selection criteria include its 4 mV max input offset voltage (C-grade), low 28 nV/√Hz input voltage noise at 1 kHz, crosstalk attenuation of 120 dB, and operation across 0°C to 70°C with ±2.25 V to ±19 V supplies.
Technical Context
The TLE2082CP uses JFET input stages for high input impedance (>100 MΩ common-mode, >6 TΩ differential) and low input bias current (≤175 nA), enabling accurate amplification of high-impedance sensor signals without loading. Its internal compensation ensures stable unity-gain operation with 56° phase margin and supports fast settling (0.25 μs to 10 mV on a 2 V step).
Designed for wide-supply-rail applications, it maintains full output swing (±4.5 V at 20 mA load with ±5 V supplies; ±14.5 V at 20 mA with ±15 V supplies) and delivers low THD+N (0.0032% at 1 kHz) - critical for audio and measurement systems requiring fidelity across dynamic range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 with minimal phase lag up to audio and low-MHz signal frequencies |
| Slew rate | 32 V/μs - supports clean reproduction of 10 VPP signals up to ~500 kHz without slewing distortion |
| Input offset voltage (max) | 7 mV (TLE2082CP, 0°C–70°C) - sets DC error floor in precision gain stages and active filters |
| Supply voltage range | ±2.25 V to ±19 V - accommodates industrial ±15 V rails and battery-powered ±5 V systems |
| Crosstalk attenuation | 120 dB - isolates channel 1 and channel 2 in dual-amplifier configurations, preventing inter-channel interference |
| Input voltage noise | 28 nV/√Hz @ 1 kHz - preserves SNR in low-level signal amplification (e.g., piezoelectric sensors, medical electrodes) |
| Common-mode input range | –10.9 V to +15 V @ ±15 V supplies - allows rail-to-rail input handling near negative supply in single-supply derived topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CP | Lower 3 MHz bandwidth, 13 V/μs slew rate, higher 15 mV VIO max, same PDIP-8 package | Acceptable where speed and precision requirements are relaxed (e.g., basic audio preamps, non-critical comparators) | Select TL082CP only if cost sensitivity outweighs need for bandwidth, noise, and DC accuracy improvements |
| OPA2134PA | Faster 8 MHz GBW, lower 8 nV/√Hz noise, FET input, SO-8 package only - no PDIP option | Preferred for audio and low-noise instrumentation where surface-mount assembly is available | Choose OPA2134PA when board space permits SOIC and superior noise performance is required; not drop-in for through-hole designs |
Compared with TL082CP and OPA2134PA, the TLE2082CP uniquely balances legacy PDIP compatibility, 10.6 MHz bandwidth, and ±19 V operation - making it optimal for upgrading existing TL082-based test equipment and industrial meters without layout changes.

FAQ
What is the maximum supply voltage rating for the TLE2082CP?
The TLE2082CP has an absolute maximum supply voltage rating of ±19 V (38 V total across VCC+ and VCC–). Operation within the recommended range of ±2.25 V to ±19 V ensures specified performance across 0°C to 70°C ambient. Exceeding ±19 V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the TLE2082CP support single-supply operation?
Yes, the TLE2082CP supports single-supply operation when biased appropriately. With VCC+ = +10 V and VCC– = 0 V, its common-mode input range extends from –0.9 V to +5 V (at 25°C), and output swings from ~0.5 V to ~9.5 V under light load. External DC biasing of inputs is required to keep signals within this valid range.
What is the input offset voltage specification for the TLE2082CP at room temperature?
The TLE2082CP has a maximum input offset voltage of 7 mV at 25°C and full operating temperature range (0°C to 70°C), per the "TLE2082C Electrical Characteristics" table. The typical value is 0.9 mV, and the TLE2082AC variant tightens this to 4 mV max at 25°C.
How does the TLE2082CP compare to the TL082CP in terms of bandwidth and slew rate?
The TLE2082CP offers 10.6 MHz unity-gain bandwidth and 32 V/μs slew rate - more than triple the 3 MHz bandwidth and 13 V/μs slew rate of the TL082CP. This enables accurate amplification of faster signals with reduced distortion, especially in pulse and video applications where edge fidelity matters.
Is the TLE2082CP pin-compatible with other dual op-amps in PDIP-8 packages?
Yes, the TLE2082CP uses the industry-standard dual op-amp pinout (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+) and is pin-compatible with TL082CP, TL072CP, and NE5532P. No PCB layout changes are needed when upgrading - only validation of system-level AC/DC performance margins.
