Product details
Overview
TLE2071IDR from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±19V supply rails, 10MHz unity-gain bandwidth, 32V/μs slew rate, 17nV/√Hz input voltage noise at 1kHz, and ±15pA input bias current - enabling accurate signal conditioning in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2071IDR datasheet, TLE2071IDR pinout, TLE2071IDR application, or TLE2071IDR equivalent, this page provides verified specifications, SOIC-8 package details, functional context for high-precision analog front-ends, and validated alternative options for industrial and aerospace-grade designs.
Technical Context
The TLE2071IDR uses Excalibur JFET-input architecture with on-chip Zener trimming for low offset drift, supporting rail-to-rail differential input operation up to ±19V supplies. Its wide common-mode range (−10.8V to +15V at ±15V supplies) and high open-loop gain (>95dB at 10kΩ load) enable stable closed-loop performance in high-gain sensor interfaces.
Designed for unity-gain stability, it features 56° phase margin with 25pF capacitive load and delivers 300kHz full-power bandwidth at ±10V output swing. The device maintains low THD+N (0.0032%) and high CMRR (98dB) under ±15V operation - critical for AC charging station current sensing and DMM front-end amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25V to ±19V - supports wide dynamic signal range in high-voltage industrial systems without external level-shifting. |
| Input Offset Voltage (max) | 4mV at 25°C (I-suffix grade) - ensures <±0.1% gain error in 10V-range precision measurement circuits. |
| Unity-Gain Bandwidth | 10.6MHz - enables stable amplification of fast transients in oscilloscope vertical amplifiers and data acquisition front-ends. |
| Slew Rate | 32V/μs - preserves fidelity of >1MHz step signals in pulse-width modulated motor drive feedback loops. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - minimizes noise floor contribution in low-level sensor signal chains (e.g., shunt-based current sensing). |
| Input Bias Current | ±15pA typical - prevents significant DC error in high-impedance photodiode or piezoelectric sensor interfaces. |
| Common-Mode Input Range | −10.8V to +15V at ±15V supply - allows direct connection to bipolar sensor outputs without attenuation or clamping. |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer for manual input offset trimming; unused in standard configurations. |
| 2 | Inverting Input (IN−) | Differential input node; high-impedance JFET gate structure enables minimal loading of source networks. |
| 3 | Non-Inverting Input (IN+) | Differential input node; supports common-mode voltages beyond supply rails by up to 0.5V. |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to suppress ground bounce in high-speed switching environments. |
| 5 | Offset Null (N2) | Second terminal of offset null network; used with Pin 1 for precision calibration in metrology-grade instruments. |
| 6 | Output (OUT) | Class-AB output stage capable of ±20mA continuous drive into 600Ω loads with <1mV settling error. |
| 7 | VCC+ | Positive supply rail connection; requires low-ESR ceramic bypass capacitor (0.1μF) placed within 2mm of pin. |
| 8 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding permitted per TI design guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input stage | 17nV/√Hz input voltage noise at 1kHz enables sub-μV resolution in 16-bit data acquisition systems. |
| Zener-trimmed input offset | ±300µV typical offset (TLE2071A variant) reduces calibration overhead in portable multimeters and battery-powered sensors. |
| Rail-to-rail differential input | Accepts inputs up to VCC± +0.5V - eliminates need for input attenuators in high-voltage motor phase current monitoring. |
| High slew rate & bandwidth | 32V/μs slew rate with 10.6MHz GBW supports accurate reproduction of 1–2MHz PWM edge transitions in inverters. |
| Wide supply range | Operates from ±2.25V to ±19V - simplifies power architecture in multi-rail test equipment and avionics subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1nV/√Hz), lower offset (25µV max), but narrower supply range (±18V max) and higher quiescent current (3.6mA vs. 2.48mA). | Better suited for ultra-low-noise audio or medical instrumentation; less ideal for high-voltage industrial monitoring where supply headroom is critical. | Select OPA211IDR when noise dominates system budget and supply rails ≤±18V; retain TLE2071IDR for ±19V operation or cost-sensitive industrial BOMs. |
| AD8610ARZ | Higher slew rate (65V/μs), wider bandwidth (25MHz), but higher input bias current (1pA vs. 15pA) and limited common-mode range (to VCC− +1V). | Preferred for high-speed active filters and laser diode drivers; unsuitable for high-common-mode sensor interfaces like shunt amplifiers. | Choose AD8610ARZ for bandwidth-critical closed-loop systems requiring >20MHz; use TLE2071IDR where input stage robustness and rail tolerance outweigh raw speed. |
Compared with OPA211IDR and AD8610ARZ, the TLE2071IDR uniquely balances ±19V operation, 17nV/√Hz noise, and JFET input integrity - making it the only option among the three qualified for high-voltage, high-precision metering and aerospace sensor conditioning without external level-shifting or gain compensation.

FAQ
What is the maximum supply voltage rating for the TLE2071IDR?
The TLE2071IDR supports absolute maximum supply voltages of ±19V, with recommended operating range from ±2.25V to ±19V. This allows direct integration into high-voltage industrial systems such as AC drive power stages and EVSE monitoring circuits without external regulation or attenuation. Operation beyond ±19V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the TLE2071IDR require external offset nulling in precision applications?
The TLE2071IDR does not require external offset nulling for most applications: its maximum input offset voltage is 4mV at 25°C (I-suffix grade), and typical offset is ±300µV for the A-grade variant. Pins 1 and 5 are provided for optional trimming via a 10kΩ potentiometer, but this is only necessary in metrology-grade instruments demanding sub-100µV offset stability over temperature.
Can the TLE2071IDR drive capacitive loads up to 100pF without instability?
The TLE2071IDR is unity-gain stable with up to 25pF capacitive load, as confirmed by phase margin measurements (56° at 25pF). Driving >25pF loads - such as long PCB traces or scope probe inputs - requires isolation resistance (e.g., 50Ω series resistor) or closed-loop compensation. TI's datasheet Figure 6-15 shows open-loop output impedance peaking near 1MHz, indicating potential ringing above 25pF.
What is the guaranteed common-mode input voltage range for the TLE2071IDR at ±15V supply?
At ±15V supply, the TLE2071IDR guarantees a common-mode input voltage range of −10.8V to +15V over the full −40°C to +85°C operating temperature range. This exceeds the supply rails by 0.5V on the positive side and extends 0.8V beyond the negative rail - enabling direct interface with bipolar sensors and high-side current monitors without level-shifting circuitry.
How does the TLE2071IDR's noise performance compare to standard bipolar-input op-amps?
The TLE2071IDR's 17nV/√Hz input voltage noise at 1kHz is significantly lower than typical bipolar-input op-amps (e.g., LM741: ~20nV/√Hz; NE5532: ~5nV/√Hz but with higher bias current). Its JFET input yields both low voltage noise and ultra-low input bias current (±15pA), making it superior to bipolar alternatives in high-impedance, low-level signal chains like piezoelectric sensor amplifiers and photodiode transimpedance stages where current noise dominates.
