Product details
Overview
TLE2082CPG4 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, high-speed data acquisition front-ends, and oscilloscope vertical amplifiers.
For engineers reviewing the TLE2082CPG4 datasheet, TLE2082CPG4 pinout, TLE2082CPG4 application, or TLE2082CPG4 equivalent, this page provides verified electrical specifications, dual-channel pin mapping, real-world use cases in metering and power electronics, and validated alternative options for design flexibility and supply continuity.
Technical Context
The TLE2082CPG4 employs a JFET-input stage with high input impedance (>100 MΩ common-mode, >6 TΩ differential) and low input bias current (15–175 nA), enabling accurate amplification of high-impedance sensor signals without loading. Its Excalibur process delivers low noise (7 nV/√Hz at ±15 V, 1 kHz) and fast settling (0.25 μs to 10 mV on a 2 V step).
It features rail-to-rail output swing capability (±14.5 V at ±15 V supplies, 20 mA load), wide common-mode input range (–10.9 V to +15 V at ±15 V), and stable unity-gain operation with 56° phase margin-making it suitable for closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - supports stable gain-of-1 amplification up to ~10 MHz without oscillation |
| Slew rate | 32 V/μs - enables faithful reproduction of fast transients (e.g., 100 ns rise time for 3.2 V step) |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in industrial and test equipment |
| Input offset voltage (max) | 6 mV at 25°C - ensures <0.1% gain error in unity-gain buffer applications with 6 V full-scale |
| Common-mode input range | –10.9 V to +15 V at ±15 V supply - accepts inputs near negative rail, critical for single-supply-derived bipolar systems |
| Output voltage swing | ±14.5 V at ±15 V, 20 mA load - delivers >96% of rails into moderate loads, minimizing headroom loss |
| Crosstalk attenuation | 120 dB - isolates channel 1 and channel 2 signals in dual-amplifier topologies (e.g., differential receiver pairs) |

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 bandwidth (4 MHz), slower slew rate (13 V/μs), higher input offset (15 mV max), same PDIP-8 package | Acceptable where speed and precision requirements are relaxed (e.g., basic audio preamps, non-critical filters) | Select when cost sensitivity outweighs performance needs and legacy designs require minimal validation |
| OPA2134PA | Higher precision (500 μV VIO max), lower noise (8 nV/√Hz), wider supply (±18 V), SO-8 only - no PDIP option | Better suited for audio and low-noise instrumentation; incompatible with through-hole layouts requiring PDIP | Choose for new designs prioritizing audio fidelity or ultra-low distortion, provided SO-8 assembly is feasible |
Compared with TL082CP and OPA2134PA, the TLE2082CPG4 uniquely balances high speed (10.6 MHz), high voltage (±19 V), and PDIP-8 compatibility-making it the only drop-in upgrade path for legacy TL082-based industrial equipment needing improved bandwidth without layout revision.

FAQ
What is the maximum supply voltage for the TLE2082CPG4?
The TLE2082CPG4 supports a total supply voltage (VCC+ to VCC−) of up to 38 V, corresponding to ±19 V operation. This rating is confirmed in Section 6.1 Absolute Maximum Ratings of the TI datasheet SLOS182C. Operating beyond ±19 V risks permanent damage, and recommended conditions specify ±2.25 V to ±19 V for reliable functionality. The TLE2082CPG4 leverages this wide rail to interface directly with industrial ±15 V systems without level-shifting.
Is the TLE2082CPG4 pin-compatible with the TL082CP?
Yes, the TLE2082CPG4 is fully pin-compatible with the TL082CP in the PDIP-8 package. Pin functions-including 1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, and VCC+-match identically per Table 5-2 and Figure 5-2 of the TLE208x datasheet. No PCB modification is required for replacement, and the TLE2082CPG4 delivers immediate performance gains in bandwidth (+165%), slew rate (+146%), and supply range (+26%) over TL082CP.
What is the typical input bias current of the TLE2082CPG4 at 25°C?
The typical input bias current of the TLE2082CPG4 is 15 nA at 25°C under ±5 V supply conditions, with a maximum of 175 nA across the 0°C to 70°C operating range. This value is specified in Section 6.12 Electrical Characteristics (TLE2082C) of the datasheet. The low bias current enables accurate amplification of signals from high-impedance sources such as photodiode transimpedance stages or capacitive sensors without significant DC error.
Does the TLE2082CPG4 support unity-gain stable operation?
Yes, the TLE2082CPG4 is unity-gain stable, with a measured phase margin of 56° at unity gain (AVD = –1) with 25 pF capacitive load and 2 kΩ load resistance, per Section 6.5 Operating Characteristics. This stability eliminates the need for external compensation in voltage-follower, inverting, or non-inverting configurations-simplifying design and reducing bill-of-materials count in precision analog signal paths.
What is the common-mode input voltage range for the TLE2082CPG4 at ±15 V supply?
At ±15 V supply, the TLE2082CPG4 supports a common-mode input voltage range of –10.9 V to +15 V, as specified in Section 6.14 Electrical Characteristics (TLE2082C). This extends 10.9 V below the negative rail, enabling operation with inputs referenced to ground or negative bias points-critical for single-ended-to-differential conversion and current-sense amplifier topologies in AC drive modules.
