Product details
Overview
TLE2071ID 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, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate signal conditioning in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2071ID datasheet, TLE2071ID pinout, TLE2071ID application, or TLE2071ID equivalent, this device is selected for designs requiring rail-to-rail differential input operation, low bias current (±15pA), stable AC performance across −40°C to +85°C, and compatibility with ±2.25V to ±19V supplies without external compensation.
Technical Context
The TLE2071ID uses Excalibur JFET-input architecture with on-chip Zener trimming for offset voltage stability. Its internal compensation ensures unity-gain stability while supporting wide common-mode input range (up to ±11.9V at ±15V supplies) and high open-loop gain (>95dB at 10kΩ load).
It operates across −40°C to +85°C with guaranteed specifications including 4mV max input offset voltage (25°C), 85dB min CMRR, and 99dB supply-voltage rejection ratio - making it suitable for industrial-grade analog front-ends where DC precision and dynamic signal fidelity must coexist.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2134PA | Lower input bias current (±0.2pA), higher cost, SOIC-8 but no offset null pins | Better for ultra-high-Z sources (e.g., photodiode transimpedance); less suitable for manual offset trimming | Select when sub-picoampere IIB is mandatory and offset adjustment is handled digitally |
| TL071CP | Higher input noise (18nV/√Hz), wider VIO spread (10mV max), same SOIC-8 pinout but no offset null terminals | Cost-optimized general-purpose use; not recommended for metrology-grade accuracy or low-noise AC coupling | Choose only for non-critical signal paths where 17nV/√Hz noise and 4mV VIO are not required |
Compared with OPA2134PA and TL071CP, the TLE2071ID uniquely combines factory-trimmed offset voltage (via Pins 1/5), JFET-input low-noise performance, and industrial temperature range - making it the preferred choice for calibrated instrumentation where manual offset correction and thermal stability are design requirements.

FAQ
What is the maximum supply voltage rating for the TLE2071ID?
The TLE2071ID supports supply voltages up to ±19V, as specified in its Absolute Maximum Ratings table. This allows operation in high-dynamic-range applications such as industrial power monitoring and oscilloscope vertical amplifiers where extended headroom is essential. Exceeding ±19V risks permanent damage, and operation above ±15V requires verification of power dissipation limits under load.
Does the TLE2071ID require external compensation for unity-gain stability?
No, the TLE2071ID is internally compensated and unity-gain stable per its datasheet specifications. It achieves 56° phase margin at unity gain with 25pF capacitive load and 2kΩ load resistance. External compensation is unnecessary for standard gain-of-one buffers or inverting/non-inverting configurations - reducing design complexity and PCB area.
How does the TLE2071ID's offset null functionality work?
The TLE2071ID provides dedicated offset null pins (1 and 5) that connect to an external 10kΩ potentiometer wiper and ends. Adjusting this potentiometer injects opposing currents into the input stage to cancel inherent input offset voltage. This manual trimming capability enables sub-millivolt DC accuracy in precision instrumentation where auto-zero or chopper architectures are unsuitable due to noise or bandwidth constraints.
Can the TLE2071ID drive heavy capacitive loads directly?
The TLE2071ID is not optimized for direct heavy capacitive loading (e.g., >100pF). Its phase margin degrades with increasing capacitive load, risking instability. For driving cables or ADC input capacitance, TI recommends using a series resistor (e.g., 50Ω) between the TLE2071ID output and the load, or selecting a driver-stage op-amp. The TLE2071ID datasheet specifies stability with ≤25pF CL at unity gain.
What is the guaranteed input offset voltage specification for the TLE2071ID over temperature?
The TLE2071ID guarantees a maximum input offset voltage of 5.6mV across its full operating range of −40°C to +85°C, with a typical value of 0.47mV at 25°C. Its temperature coefficient is 3.2μV/°C max, meaning offset drift contributes less than 0.5mV over the full range - critical for maintaining accuracy in uncalibrated industrial sensor interfaces where the TLE2071ID is commonly deployed.
