Product details
Overview
TLE2082ACDR 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, ±19 V supply capability, and 4 mV max input offset voltage at 25°C. It serves as a direct upgrade to TL072/TL082 in precision AC-coupled signal conditioning stages of oscilloscopes, data acquisition systems, and industrial metering.
For engineers reviewing the TLE2082ACDR datasheet, TLE2082ACDR pinout, TLE2082ACDR application, or TLE2082ACDR equivalent, this device supports high-dynamic-range analog front-ends where wide supply rails, low noise (7 nV/√Hz at 1 kHz, ±15 V), and fast settling (0.4 μs to 1 mV) are critical for fidelity in battery-powered test equipment and motor control feedback loops.
Technical Context
The TLE2082ACDR implements a JFET-input differential pair with high-impedance inputs (100 MΩ common-mode, 6 TΩ differential), enabling low bias current (15–175 nA) and stable DC precision across temperature. Its internal compensation ensures 56° phase margin at unity gain with 25 pF load, supporting stable operation in unity-gain follower and active filter configurations.
It operates over 0°C to 70°C ambient (C-suffix grade), supports rail-to-rail output swing within ±1.5 V of rails at 20 mA load, and maintains 120 dB crosstalk attenuation between channels-critical for dual-channel instrumentation where channel isolation prevents signal coupling in multi-sensor measurement systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop operation up to ~1 MHz with gain ≥ 10, suitable for anti-aliasing filters in 1 MSPS data acquisition. |
| Slew rate | 32 V/μs - supports full-scale 10 Vpp output transitions in under 313 ns, essential for pulse amplification and fast-settling DAC buffers. |
| Input offset voltage (max) | 4 mV at 25°C - limits DC error to ≤0.04% of 10 V full scale, sufficient for 8-bit system accuracy without trimming. |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic signal range in ±15 V industrial systems and ±5 V portable designs without level-shifting. |
| Input bias current (max) | 175 nA - permits use with high-impedance sensor sources (e.g., piezoelectric transducers, pH electrodes) without significant loading error. |
| Crosstalk attenuation | 120 dB - ensures <0.0001% inter-channel signal leakage, preserving integrity in dual-channel DMMs and differential line receivers. |
| Output short-circuit current | ±65 mA - sustains drive into 100 Ω loads or capacitive cables without latch-up, supporting robust probe driver and line driver applications. |
Pinout & Package
SOIC-8 (D) package, 4.9 mm × 6.0 mm body, gull-wing leads, tape-and-reel delivery (R suffix). RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Amplified output of first op-amp; drives external load or next stage with ±65 mA capability. |
| 1IN– | Inverting Input, Channel 1 | High-impedance (6 TΩ) node for feedback network connection; sets gain and stability in inverting configurations. |
| 1IN+ | Non-inverting Input, Channel 1 | High-impedance (6 TΩ) node for reference or sensor input; rejects common-mode noise up to 85 dB. |
| VCC– | Negative Supply Rail | Connects to system ground or negative rail; must be decoupled locally with 0.1 μF ceramic capacitor. |
| 2IN+ | Non-inverting Input, Channel 2 | Independent input for second amplifier; enables dual-path signal processing without shared impedance nodes. |
| 2IN– | Inverting Input, Channel 2 | Independent inverting input; allows separate gain-setting resistors per channel to avoid mismatch-induced crosstalk. |
| 2OUT | Output, Channel 2 | Second independent output; supports differential output generation or parallel channel buffering. |
| VCC+ | Positive Supply Rail | Connects to system positive rail; requires local 0.1 μF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Direct TL072/TL082 upgrade | Pins 1–8 match TL072 footprint and function, enabling drop-in replacement without PCB revision in legacy designs. |
| Wider supply rails (±19 V) | Extends usable input/output swing by ±4 V versus TL082 (±15 V), reducing clipping risk in high-voltage sensor interfaces. |
| Low 1/f noise (2.77 μVPP, 0.1–10 Hz) | Minimizes baseline drift in precision integrators and low-frequency instrumentation amplifiers used in energy metering. |
| High CMRR (85 dB) | Rejects power-supply ripple and EMI coupling on shared rails, improving SNR in noisy industrial environments. |
| Low THD+N (0.0032%) | Preserves waveform fidelity in audio preamps and function generator outputs where harmonic distortion degrades signal purity. |
Applications
| Oscilloscopes and Digitizers | Electricity Meter Front-End |

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 |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher VIO (10 mV max), no R-suffix tape-and-reel option in D package. | Acceptable for <100 kHz signal paths but insufficient for >1 MSPS data acquisition or fast pulse shaping. | Select when cost sensitivity outweighs speed/precision needs and legacy TL072 design reuse is required. |
| OPA2134PA | Higher precision (0.5 mV VIO), lower noise (8 nV/√Hz), but narrower supply (±18 V) and slower slew (20 V/μs). | Better for audio and sensor signal chains requiring ultra-low distortion; less suitable for fast transient response. | Choose for low-noise, low-distortion audio preamps or precision sensor interfaces where 32 V/μs is not mandatory. |
Compared with TL072CDR, TLE2082ACDR delivers >3× bandwidth and half the input offset; versus OPA2134PA, it trades 1.5× lower noise for 1.6× faster slew rate and superior output drive-making it optimal for mixed-signal test equipment demanding both speed and robustness.

FAQ
What is the maximum operating temperature range for the TLE2082ACDR?
The TLE2082ACDR is rated for 0°C to 70°C ambient operating temperature (C-suffix grade). This range aligns with commercial-grade instrumentation and portable test equipment. For extended temperature operation, TI offers the TLE2082AIDR (–40°C to 85°C) and TLE2082AMJG (–55°C to 125°C) variants, but the TLE2082ACDR itself is specified only up to +70°C.
Does the TLE2082ACDR support single-supply operation?
Yes, the TLE2082ACDR supports single-supply operation with VCC+ = +3.5 V to +38 V and VCC– = ground, provided the input common-mode and output swing ranges remain within specification. At ±5 V dual supply, its input common-mode range extends from –0.9 V to +5 V; referenced to ground in single-supply mode, this translates to 0 V to +4.1 V with appropriate biasing.
What is the typical input capacitance of the TLE2082ACDR?
The TLE2082ACDR exhibits 1 pF common-mode input capacitance and 9 pF differential input capacitance at 25°C, as measured with VIC = 0 V. These values remain stable across temperature and supply voltage, enabling predictable frequency response in high-impedance sensor interfaces and active filter designs without parasitic resonance concerns.
How does the TLE2082ACDR's crosstalk attenuation compare to standard dual op-amps?
The TLE2082ACDR achieves 120 dB crosstalk attenuation between channels at 25°C, significantly exceeding typical dual op-amps (often 80–100 dB). This is achieved via isolated die layout and optimized substrate coupling control, making it suitable for dual-channel DMMs and oscilloscope front-ends where inter-channel interference must be below 0.0001%.
Can the TLE2082ACDR drive a 600 Ω load at full output swing?
Yes-the TLE2082ACDR delivers ±13.5 V output swing into 2 mA load (equivalent to 6.75 kΩ), and its ±65 mA short-circuit current capability ensures stable operation into 600 Ω. At ±15 V supply, it sustains ±13.5 V into 2 mA; for 600 Ω, that corresponds to ±13.5 V / 600 Ω = 22.5 mA, well within its ±65 mA limit, with minimal distortion (<0.0032% THD+N).
