Product details
Overview
TLE2071AID from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-precision, low-noise signal conditioning in industrial and test equipment. It delivers ±300 µV typical input offset voltage, 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz unity-gain bandwidth, ±19 V supply capability, 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 TLE2071AID datasheet, TLE2071AID pinout, TLE2071AID application, or TLE2071AID equivalent, this page provides verified specifications, SOIC-8 package layout, real-world use cases in metering and instrumentation, and validated alternative options for design flexibility and supply continuity.
Technical Context
The TLE2071AID uses Excalibur JFET-input architecture with on-chip Zener trimming for low offset drift and high input impedance (>10¹² Ω). Its wide supply range (±2.25 V to ±19 V) enables direct interfacing with high-voltage sensor outputs without level-shifting.
It features unity-gain stability, 32 V/µs slew rate, and rail-to-rail input common-mode range - allowing differential inputs up to the supply rails. The device maintains low THD+N (0.0032%) and high CMRR (98 dB at ±15 V), making it suitable for precision DC-coupled amplification and AC-coupled high-fidelity signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±300 µV typ at 25°C - enables sub-millivolt DC accuracy in sensor front-ends without external nulling. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals in DMMs and digitizers. |
| Unity-Gain Bandwidth | 10.6 MHz - allows stable operation at gains ≥1 with fast settling (0.4 µs to 1 mV for 10 V step). |
| Supply Voltage Range | ±2.25 V to ±19 V - accommodates high-dynamic-range industrial sensors and legacy ±15 V systems. |
| Input Bias Current | ±15 pA max at 25°C - preserves signal integrity in high-impedance pH probes, piezoelectric sensors, and photodiode transimpedance stages. |
| Common-Mode Input Range | Extends to within 0.8 V of rails at ±15 V - permits direct connection to unbuffered ADC drivers and bipolar signal sources. |
| Slew Rate | 32 V/µs - ensures faithful reproduction of fast transient waveforms in oscilloscope vertical amplifiers. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6.0 mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Adjustment terminal for fine-tuning input offset; unused in standard configurations but enables <100 µV calibration. |
| 2 | Inverting Input (–) | High-impedance JFET node; accepts differential or single-ended feedback signals with minimal loading. |
| 3 | Non-Inverting Input (+) | High-impedance JFET node; used for reference biasing or positive feedback in active filters. |
| 4 | V– (Negative Supply) | Connects to negative rail; supports operation down to –19 V for bipolar signal processing. |
| 5 | Offset Null (N2) | Second adjustment terminal paired with Pin 1; required only when external nulling is implemented. |
| 6 | Output | Capable of ±20 mA drive into 600 Ω; delivers full swing (±14.5 V at ±15 V supplies) with low distortion. |
| 7 | V+ (Positive Supply) | Connects to positive rail; supports operation up to +19 V for extended headroom in high-voltage applications. |
| 8 | No Connect (NC) | Internally unused; must remain floating per TI design - no tie-to-ground or bypassing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), lower offset (±25 µV), but narrower supply (±18 V max) and higher quiescent current (3.6 mA vs. 2.48 mA). | Better suited for ultra-low-noise audio or medical instrumentation; less ideal for high-voltage industrial monitoring due to tighter supply margin. | Select OPA211IDR where noise dominates design requirements and supply rails stay ≤±18 V. |
| TL071CDR | Higher offset (±10 mV), higher noise (18 nV/√Hz), same SOIC-8 package and ±18 V rating; no Zener trimming. | Cost-optimized general-purpose replacement; lacks TLE2071AID's precision for metrology or high-resolution DMMs. | Choose TL071CDR for non-critical signal conditioning where ±10 mV offset is acceptable and BOM cost is prioritized. |
Compared with OPA211IDR and TL071CDR, the TLE2071AID uniquely balances low noise (17 nV/√Hz), tight offset (±300 µV), and robust ±19 V operation - making it the optimal choice for industrial metering and test equipment requiring both precision and high-voltage resilience.

FAQ
What is the maximum supply voltage for the TLE2071AID?
The TLE2071AID supports a total supply voltage range of ±2.25 V to ±19 V, meaning the absolute maximum difference between V+ and V– is 38 V. This allows operation in legacy ±15 V systems and newer ±18 V industrial designs while maintaining specified performance across the full range.
Does the TLE2071AID require external offset nulling in most applications?
No - the TLE2071AID incorporates on-chip Zener trimming, resulting in a typical input offset voltage of ±300 µV at 25°C and ±2 mV maximum over –40°C to +85°C. External nulling via Pins 1 and 5 is optional and only needed when sub-100 µV offset is required for metrology-grade applications.
Can the TLE2071AID drive a 600 Ω load at full output swing?
Yes - the TLE2071AID delivers ±14.5 V output swing into a 600 Ω load at ±15 V supplies, with large-signal differential voltage gain exceeding 96 dB. Its ±65 mA short-circuit output current ensures robust drive capability without thermal shutdown under sustained load conditions.
Is the TLE2071AID unity-gain stable, and what does that mean for circuit design?
Yes - the TLE2071AID is explicitly unity-gain stable, meaning it remains stable with closed-loop gain ≥1 without requiring external compensation capacitors. This simplifies design of buffers, active filters, and integrators, reducing component count and board space versus decompensated op-amps.
How does the TLE2071AID compare to the standard TLE2071ID in terms of precision?
The TLE2071AID offers tighter specifications than the TLE2071ID: its maximum input offset voltage is ±2 mV (vs. ±4 mV for TLE2071ID) and its typical offset is ±300 µV (vs. ±490 µV). Both share identical pinout, package, and operating temperature range (–40°C to +85°C), making the TLE2071AID a drop-in upgrade for higher-accuracy designs.
