Product details
Overview
TLE2082ACDRG4 from Texas Instruments is a dual high-speed JFET-input operational amplifier in SOIC-8 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 front-ends.
For engineers reviewing the TLE2082ACDRG4 datasheet, TLE2082ACDRG4 pinout, TLE2082ACDRG4 application, or TLE2082ACDRG4 equivalent, key selection criteria include its 4 mV max input offset voltage (25°C), low 28 nV/√Hz input voltage noise at 1 kHz, crosstalk attenuation of 120 dB, and operation across 0°C to 70°C ambient temperature with ±2.25 V to ±19 V dual supply rails.
Technical Context
The TLE2082ACDRG4 uses a JFET-input stage enabling high input impedance (>100 MΩ common-mode, >6 TΩ differential) and low input bias current (≤175 pA typical). Its internal compensation ensures stable unity-gain operation with 56° phase margin and supports fast settling (0.25 μs to 10 mV on 2 V step) without external components.
It operates with rail-to-rail output swing capability under light loads (±4.985 V at ±5 V supplies) and maintains 120 dB channel-to-channel isolation-critical for dual-channel instrumentation where signal integrity between channels must be preserved during simultaneous high-frequency acquisition.
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 oscillation |
| Slew rate | 32 V/μs - supports clean reproduction of 10 VPP signals up to ~500 kHz without slew-induced distortion |
| Input offset voltage (max) | 4 mV at 25°C - sets DC accuracy floor in non-inverting amplifiers with gain ≤100 |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic range in industrial sensor interfaces and power supply monitoring |
| Crosstalk attenuation | 120 dB - prevents coupling between channels in dual-signal acquisition paths such as differential pair processing |
| Input voltage noise | 28 nV/√Hz at 1 kHz - limits detectable signal amplitude in 10 kHz bandwidth applications to ~2.8 μVRMS |
| Operating temperature | 0°C to 70°C - qualified for commercial-grade embedded instrumentation and test equipment |

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 |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher input offset (10 mV max), no crosstalk spec | Limited to lower-speed signal chains; unsuitable for >100 kHz acquisition or precision DMM front-ends | Select when cost sensitivity outweighs speed/accuracy needs and ±15 V operation suffices |
| OPA2134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but 8 MHz bandwidth and ±18 V max supply | Better for ultra-low-noise audio or medical instrumentation; less suitable for high-slew industrial pulse capture | Choose for DC-critical, low-frequency applications where 32 V/μs slew is unnecessary |
Compared with TL072CDR and OPA2134PA, the TLE2082ACDRG4 uniquely balances high slew rate, wide supply range, and dual-channel isolation-making it optimal for industrial test equipment requiring both speed and channel independence without layout-level isolation.

FAQ
What is the maximum supply voltage rating for the TLE2082ACDRG4?
The TLE2082ACDRG4 supports dual-supply operation from ±2.25 V up to ±19 V, as specified in the Absolute Maximum Ratings table. This allows direct interfacing with ±15 V industrial sensor outputs and provides ample headroom for transient suppression in harsh environments. Exceeding ±19 V risks permanent damage per TI's datasheet SLOS182C Section 6.1.
Does the TLE2082ACDRG4 require external compensation for unity-gain stability?
No, the TLE2082ACDRG4 is internally compensated for stable unity-gain operation with a phase margin of 56° at 25°C. Its design eliminates the need for external compensation capacitors in standard non-inverting or inverting configurations with gain ≥1, simplifying PCB layout and reducing bill-of-materials count compared to decompensated op-amps like the OPA627.
What is the input offset voltage specification for the TLE2082ACDRG4 at room temperature?
The TLE2082ACDRG4 has a maximum input offset voltage of 4 mV at 25°C, per the TLE2082AC electrical characteristics table (Section 6.12). This value applies to the "A" grade variant and reflects worst-case performance across process and temperature extremes within the C-suffix commercial temperature range (0°C to 70°C).
How does crosstalk performance impact dual-channel use cases for the TLE2082ACDRG4?
The TLE2082ACDRG4 specifies 120 dB crosstalk attenuation between channels, meaning a 1 V signal on Channel 1 induces less than 1 μV of coupled error on Channel 2. This enables accurate simultaneous measurement of independent signals-such as differential voltage and current in power analyzers-without dedicated isolation circuitry or physical separation on the PCB.
Is the TLE2082ACDRG4 pin-compatible with legacy TL082 or TL072 devices?
Yes, the TLE2082ACDRG4 uses the industry-standard SOIC-8 pinout matching TL072 and TL082, enabling drop-in replacement in existing designs. Key compatible pins include 1OUT/1IN–/1IN+/VCC–/2IN+/2IN–/2OUT/VCC+. No PCB changes are required, though system-level validation of bandwidth, noise, and settling behavior is recommended due to its higher performance envelope.
