Product details
Overview
TLE2082CD 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 7 mV over temperature), low noise (28 nV/√Hz at 1 kHz), and high CMRR (85 dB), making it suitable for precision AC signal conditioning in oscilloscopes and high-speed data acquisition systems.
For engineers reviewing the TLE2082CD datasheet, TLE2082CD pinout, TLE2082CD application, or TLE2082CD equivalent, this device serves as a direct upgrade to TL082 and TL072 op-amps in high-bandwidth, wide-supply-rail analog front-ends where DC precision and AC performance must coexist - especially in test equipment and industrial metering.
Technical Context
The TLE2082CD uses a JFET-input stage enabling high input impedance (>100 MΩ common-mode, >6 TΩ differential) 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 under 25 pF load.
It operates across 0°C to 70°C ambient, supports rail-to-rail output swing within ±1.5 V of rails at 20 mA load, and maintains 90 dB THD+N suppression at 1 kHz - critical for low-distortion amplification in portable DMMs and battery-powered instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 with ≤1% gain error up to 10 MHz |
| Slew rate | 32 V/μs - supports clean 10 VPP sinusoidal output up to ~500 kHz without slewing distortion |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in high-voltage sensor interfaces |
| Input offset voltage (max) | 7 mV over 0°C–70°C - limits DC error to <0.35% of 2 V full-scale in precision gain stages |
| CMRR | 85 dB - rejects >17,700:1 common-mode interference in single-ended measurement paths |
| THD + N | 0.0032% at 1 kHz - preserves signal fidelity in audio and metrology-grade amplification |
| Crosstalk attenuation | 120 dB - isolates channel 1 from channel 2 signals in dual-channel acquisition front-ends |

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 |
|---|---|---|---|
| TL082CD | Lower bandwidth (4 MHz), slower slew rate (13 V/μs), higher input offset (15 mV max), no guaranteed 120 dB crosstalk | Acceptable for <100 kHz general-purpose amplification but insufficient for oscilloscope front-ends or high-resolution DMMs | Select TL082CD only when cost is primary constraint and bandwidth/noise requirements are relaxed |
| OPA2134PA | Higher precision (500 μV VIO max), lower noise (8 nV/√Hz), but narrower supply range (±18 V max) and no specified crosstalk spec | Better for audio and ultra-low-drift instrumentation; less suited for high-voltage industrial monitoring | Choose OPA2134PA when sub-millivolt DC accuracy and audio-grade THD are mandatory |
Compared with TL082CD and OPA2134PA, the TLE2082CD uniquely balances high speed (10.6 MHz), wide supply (±19 V), and production-grade DC specs (7 mV VIO) - making it optimal for cost-sensitive, high-performance industrial test and energy metering designs where both bandwidth and robustness matter.

FAQ
What is the maximum supply voltage rating for the TLE2082CD?
The TLE2082CD 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 ±19 V, enabling ±14.5 V output swing at 20 mA load - critical for high-dynamic-range sensor interfaces in the TLE2082CD design envelope.
Does the TLE2082CD support unity-gain stable operation?
Yes, the TLE2082CD is internally compensated for unity-gain stability, with 56° phase margin at unity gain and 25 pF capacitive load. Its 10.6 MHz unity-gain bandwidth and 300 kHz full-output-swing bandwidth confirm stable closed-loop behavior in gain-of-1 configurations used in the TLE2082CD's typical applications.
How does the TLE2082CD compare to TL082 in terms of bandwidth and slew rate?
The TLE2082CD provides 10.6 MHz unity-gain bandwidth and 32 V/μs slew rate - more than double the 4 MHz bandwidth and 13 V/μs slew rate of the TL082. This performance uplift makes the TLE2082CD a documented direct upgrade path for TL082-based designs needing faster transient response, such as in oscilloscope vertical amplifiers using the TLE2082CD.
What is the input offset voltage specification for the TLE2082CD over temperature?
The TLE2082CD has a maximum input offset voltage of 7 mV across the full operating range of 0°C to 70°C. At 25°C, the typical value is 0.9 mV (C-grade), with a temperature coefficient of 2.3 μV/°C - ensuring predictable DC error growth in precision gain stages throughout the TLE2082CD's thermal envelope.
Is the TLE2082CD pin-compatible with other dual op-amps in SOIC-8 packages?
Yes, the TLE2082CD uses the industry-standard SOIC-8 pinout matching TL082, TL072, and TL052. Pin 1 (1OUT), Pin 2 (1IN–), Pin 3 (1IN+), Pin 4 (VCC–), Pin 5 (2IN+), Pin 6 (2IN–), Pin 7 (2OUT), and Pin 8 (VCC+) are functionally identical - enabling direct substitution in existing TL082 layouts without modification to the TLE2082CD footprint.
