Product details
Overview
TLE2071AIDG4 from Texas Instruments is a single-channel, JFET-input operational amplifier optimized for high-precision, low-noise signal conditioning in ±2.25V to ±19V supply systems. It delivers 10MHz unity-gain bandwidth, 32V/μs slew rate, ±300µV typical input offset voltage, 17nV/√Hz input voltage noise at 1kHz, and operates across −40°C to +85°C. It serves as the front-end gain stage in digital multimeters and oscilloscope analog signal paths.
For engineers reviewing the TLE2071AIDG4 datasheet, TLE2071AIDG4 pinout, TLE2071AIDG4 application, or TLE2071AIDG4 equivalent, this page provides verified package mapping (SOIC-8), confirmed pin functions (including offset null terminals), real-world AC/DC performance trade-offs, and two validated alternative op-amps for precision instrumentation design.
Technical Context
The TLE2071AIDG4 uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, enabling rail-to-rail differential input operation and wide common-mode range (−10.9V to +15V at ±15V supplies). Its 10.6MHz unity-gain bandwidth and 56° phase margin ensure stable unity-gain operation without external compensation.
It achieves low 17nV/√Hz noise floor via matched JFET input pair and optimized internal biasing, while maintaining ultra-low 15pA typical input bias current-critical for high-impedance sensor interfaces and charge-amplifier topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10.6MHz unity-gain bandwidth enables accurate amplification of signals up to ~1MHz with minimal phase error in closed-loop configurations. |
| Slew Rate | 32V/μs supports fast transient response in pulse amplification and active filter stages without slew-induced distortion. |
| Input Offset Voltage | ±300µV typical (max ±2mV) ensures <0.02% gain error in 10V full-scale precision measurement circuits. |
| Input Voltage Noise | 17nV/√Hz at 1kHz defines minimum detectable signal level in audio and sensor front-ends; 48nV/√Hz at 10Hz reflects low-frequency stability. |
| Supply Range | ±2.25V to ±19V allows direct integration into legacy industrial power rails and high-dynamic-range data acquisition systems. |
| Input Bias Current | ±15pA typical enables use with >100MΩ source impedances without significant offset drift or signal loading. |
| Common-Mode Range | Extends to within 1.9V of negative rail and 1V of positive rail at ±5V supplies-supports ground-referenced single-ended inputs. |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body, gull-wing leads, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer for manual input offset trimming; required for sub-100µV system-level calibration. |
| 2 | Inverting Input (−) | Differential input node; high-impedance JFET gate with 1pF common-mode capacitance limits RF pickup in sensitive nodes. |
| 3 | Non-Inverting Input (+) | Differential input node; matched to Pin 2 for CMRR >85dB; used for reference-biased transducer interfaces. |
| 4 | V− (Negative Supply) | Ground or negative rail connection; must be decoupled with ≥0.1µF ceramic capacitor near pin for stability. |
| 5 | Offset Null (N2) | Second terminal of offset null potentiometer; forms balanced bridge with Pin 1 to adjust input stage quiescent point. |
| 6 | Output | Capacitive-load tolerant output capable of driving 2kΩ loads with full swing; limited to ±65mA short-circuit current. |
| 7 | V+ (Positive Supply) | Positive rail connection; requires local 0.1µF ceramic + 10µF tantalum decoupling for low-noise operation. |
| 8 | No Connect (NC) | Internally unused; must remain unconnected per TI design guidelines to avoid parasitic coupling or latch-up risk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail differential input | Accepts input signals beyond supply rails by up to 0.2V, enabling direct interface with overvoltage-protected sensors. |
| Zener-trimmed offset | Reduces initial VIO to ±2mV max (vs ±4mV for standard TLE2071), lowering calibration burden in production test. |
| Low 17nV/√Hz noise | Enables 16-bit effective resolution in 10kHz bandwidth applications without external noise filtering. |
| Unity-gain stable | Operates without external compensation in gain-of-1 configurations-reducing BOM count and PCB area in buffer stages. |
| High CMRR (98dB) | Maintains accuracy in noisy industrial environments where common-mode interference exceeds 100mV peak-to-peak. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211AIDGKR | Lower 1.1nV/√Hz noise, but higher 3.5mA supply current and no offset null pins; SOIC-8 package. | Better for ultra-low-noise audio preamps; less suitable for battery-powered DMMs or systems requiring manual offset trim. | Choose when noise dominates budget and offset calibration is handled digitally. |
| ADA4625-1ARZ | 1.2nV/√Hz noise, 12MHz GBW, rail-to-rail output, but only ±15V max supply; SOIC-8 package. | Superior for high-fidelity signal chains with rail-to-rail output swing; not rated for ±19V operation like TLE2071AIDG4. | Choose when output swing headroom is constrained and supply is limited to ±15V. |
Compared with OPA211AIDGKR and ADA4625-1ARZ, the TLE2071AIDG4 uniquely balances ultra-low input bias current (15pA), wide ±19V supply capability, and user-adjustable offset trimming-making it irreplaceable in portable, high-voltage, and calibration-sensitive instrumentation.

FAQ
What is the maximum supply voltage rating for the TLE2071AIDG4?
The TLE2071AIDG4 supports a total supply voltage (V+ to V−) up to 38V, enabling operation from ±2.25V to ±19V. This wide range allows direct use in legacy industrial systems with ±15V rails and newer high-dynamic-range designs requiring ±19V headroom. Absolute maximum ratings prohibit exceeding ±19V per rail under any condition.
Does the TLE2071AIDG4 require external compensation for unity-gain stability?
No, the TLE2071AIDG4 is internally compensated and unity-gain stable. Its 56° phase margin at unity gain eliminates the need for external capacitors or feedback network adjustments-simplifying layout and reducing component count in buffer and gain-of-1 configurations.
How does the offset null functionality work on the TLE2071AIDG4?
The TLE2071AIDG4 provides dedicated offset null pins (1 and 5) that connect to a 10kΩ potentiometer wiper and ends. Adjusting this potentiometer applies a small corrective current to the input stage, trimming input offset voltage to <100µV. This is essential for applications like precision DMMs where factory calibration must be maintained over temperature.
Can the TLE2071AIDG4 drive capacitive loads directly?
The TLE2071AIDG4 can drive moderate capacitive loads (≤100pF) without instability, but larger loads require isolation resistance (e.g., 50Ω in series with output) to maintain phase margin. Its open-loop output impedance (~80Ω at 1MHz) and lack of dedicated capacitive-load drive enhancement mean external buffering is recommended for >500pF loads.
What is the guaranteed input bias current specification for the TLE2071AIDG4 over temperature?
At −40°C to +85°C, the TLE2071AIDG4 guarantees input bias current ≤±10nA (max), with ±15pA typical at 25°C. This ultra-low bias enables reliable operation with high-impedance sources such as piezoelectric sensors, photodiode transimpedance nodes, and megohm-level voltage dividers without significant error voltage buildup.
