Product details
Overview
TLE2082IDRG4 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, high-speed data acquisition front-ends, and oscilloscope vertical amplifiers.
For engineers reviewing the TLE2082IDRG4 datasheet, TLE2082IDRG4 pinout, TLE2082IDRG4 application, or TLE2082IDRG4 equivalent, key selection criteria include input offset voltage (max 7 mV at –40°C to 85°C), crosstalk attenuation (120 dB), wide common-mode range (±10.9 V at ±15 V supplies), and low 1/f noise (2.77 μVPP, 0.1 Hz to 10 Hz).
Technical Context
The TLE2082IDRG4 uses a high-voltage JFET input stage with matched P-channel devices, enabling low input bias current (≤175 nA) and high input impedance (6 TΩ differential). Its internal compensation ensures stable unity-gain operation with ≥56° phase margin into 2 kΩ loads and 25 pF capacitive loads.
It operates across –40°C to +85°C with rail-to-rail output swing capability (±14.5 V at ±15 V supplies, 20 mA load) and supports dual-supply configurations only-no single-supply operation. The device exhibits low total harmonic distortion plus noise (0.0032% at 1 kHz) and high PSRR (99 dB typical) for robust performance in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10.6 MHz - enables stable closed-loop gain ≥1 with ≤0.1% gain error up to audio and low-RF frequencies |
| Slew rate | 32 V/μs - supports full-scale 10 Vpp output transitions in ≤0.31 μs without slewing distortion |
| Input offset voltage | 7 mV max (–40°C to 85°C) - limits DC error to ≤7 mV in precision sensor amplification chains |
| Crosstalk attenuation | 120 dB - isolates channel 1 and channel 2 signals in dual-path instrumentation, preventing coupling-induced measurement drift |
| Supply voltage range | ±2.25 V to ±19 V - accommodates wide dynamic range in high-voltage analog front-ends (e.g., energy metering, motor control) |
| Common-mode input range | –10.9 V to +15 V (at ±15 V supplies) - accepts inputs within 1.1 V of negative rail, easing level-shifting design |
| THD+N | 0.0032% at 1 kHz - preserves signal fidelity in audio and test equipment applications requiring low distortion |
Pinout & Package
SOIC-8 (D) package, 4.9 mm × 6.0 mm body, gull-wing leads, RoHS-compliant, tape-and-reel (R-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output, Channel 1 | Low-impedance buffered output capable of ±65 mA short-circuit current and ±14.5 V swing into 20 mA load |
| 1IN– | Inverting Input, Channel 1 | High-impedance JFET node (6 TΩ) with 5–100 nA input bias current; requires matched trace routing to minimize offset drift |
| 1IN+ | Non-inverting Input, Channel 1 | Differential pair input referenced to same high-Z structure as 1IN–; used for unity-gain buffer or non-inverting gain stages |
| VCC– | Negative Supply Rail | Connects to system ground or negative rail; must be decoupled with 0.1 μF ceramic capacitor near pin |
| 2IN+ | Non-inverting Input, Channel 2 | Independent input for second amplifier channel; shares no internal nodes with Channel 1 except supply rails |
| 2IN– | Inverting Input, Channel 2 | Matched to 1IN– in offset and bias characteristics; enables dual-channel synchronous signal processing |
| 2OUT | Output, Channel 2 | Electrically isolated output stage; 120 dB crosstalk ensures <1 μV coupling from Channel 1 under full-scale switching |
| VCC+ | Positive Supply Rail | Accepts up to +19 V; requires local 0.1 μF + 10 μF decoupling to suppress supply-induced noise and oscillation |
Key Features
| Feature | Design Value |
|---|---|
| Direct TL072/TL082 upgrade | Pin-compatible replacement with doubled bandwidth (10.6 MHz vs. 3 MHz) and improved PSRR (99 dB vs. 90 dB) |
| High-voltage operation | ±19 V supply rating enables use in ±15 V industrial systems without derating or external regulators |
| Low 1/f noise | 2.77 μVPP (0.1 Hz–10 Hz) supports high-resolution DC-coupled measurements in digital multimeters and electricity meters |
| Thermal stability | Input offset tempco ≤25 μV/°C ensures ≤0.5 mV drift over full –40°C to +85°C operating range |

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 input offset (10 mV max), no guaranteed 120 dB crosstalk | Cost-sensitive audio and general-purpose designs where speed and channel isolation are secondary | Select when budget constraints outweigh need for >10 MHz bandwidth or metrology-grade noise performance |
| OPA2134PA | Higher precision (500 μV VIO max), lower noise (8 nV/√Hz), but narrower supply (±18 V max) and no guaranteed crosstalk spec | Audio preamplifiers and medical instrumentation requiring ultra-low distortion and DC accuracy | Choose when THD+N <0.0005% and offset <0.5 mV are mandatory, and ±15 V operation suffices |
Compared with TL072CDR and OPA2134PA, the TLE2082IDRG4 delivers superior bandwidth and crosstalk performance at moderate precision-making it optimal for industrial data acquisition where speed, channel independence, and supply headroom are prioritized over ultra-low offset or sub-0.001% THD.

FAQ
What is the maximum supply voltage for the TLE2082IDRG4?
The TLE2082IDRG4 supports a maximum supply voltage of ±19 V across its VCC+ and VCC– pins. This rating applies to both dual-supply operation and split-rail configurations. Operation beyond ±19 V risks permanent damage per Absolute Maximum Ratings. At ±15 V supplies, the device delivers full specified performance including ±14.5 V output swing and 32 V/μs slew rate.
Does the TLE2082IDRG4 support single-supply operation?
No, the TLE2082IDRG4 is not characterized or guaranteed for single-supply operation. Its input common-mode range extends only to within ~1.1 V of the negative rail, and the datasheet specifies recommended operating conditions exclusively for dual-supply configurations (±2.25 V to ±19 V). For true single-supply applications, consider TI's TLV2462 or OPA2340 families.
What is the input offset voltage specification for TLE2082IDRG4 over temperature?
The TLE2082IDRG4 has a maximum input offset voltage of 7 mV over the full operating temperature range of –40°C to +85°C. At 25°C, the typical value is 0.65 mV (TLE2082AC variant) or 0.9 mV (TLE2082C variant); the "I" suffix denotes the industrial temperature grade, and the "D" package confirms SOIC-8 packaging. Temperature coefficient is ≤25 μV/°C.
How does crosstalk performance impact dual-channel use of the TLE2082IDRG4?
The TLE2082IDRG4 guarantees 120 dB crosstalk attenuation between channels, meaning a full-scale 10 Vpp signal on Channel 1 induces less than 1 μV of coupled signal onto Channel 2's output. This enables simultaneous high-fidelity acquisition of two independent signals-such as voltage and current in power analyzers-without calibration correction for inter-channel interference.
Is the TLE2082IDRG4 pin-compatible with the TL082 series?
Yes, the TLE2082IDRG4 is pin-compatible with TL082, TL072, and TL052 in SOIC-8 (D) and PDIP-8 (P) packages. Pin functions match exactly: 1OUT/1IN–/1IN+/VCC–/2IN+/2IN–/2OUT/VCC+. No PCB layout changes are required for drop-in replacement, though decoupling and layout best practices for high-speed op-amps should still be followed.
