Product details
Overview
TLE2071AMJGB from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise precision signal conditioning in harsh environments. It delivers ±300 µV typical input offset voltage, 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz gain-bandwidth product, ±19 V supply capability, and operates across −55°C to +125°C. It serves as the front-end amplifier in electricity metering and flight control unit analog acquisition stages.
For engineers reviewing the TLE2071AMJGB datasheet, TLE2071AMJGB pinout, TLE2071AMJGB application, or TLE2071AMJGB equivalent, this page provides verified electrical specifications, ceramic DIP-8 package details, thermal performance data, and validated alternatives for aerospace-grade analog signal chains requiring rail-to-rail input operation and Zener-trimmed DC accuracy.
Technical Context
The TLE2071AMJGB uses an Excalibur JFET-input architecture with on-chip Zener trimming for offset calibration, enabling stable DC precision over extended temperature and voltage ranges. Its differential input stage supports common-mode voltages up to the supply rails, and its unity-gain-stable design ensures robustness in active filter and transimpedance configurations.
It features a 32 V/µs slew rate, 56° phase margin at unity gain, and maintains 90 dB THD+N at 1 kHz - characteristics critical for high-fidelity data acquisition in AC drive power stage feedback loops and oscilloscope vertical amplifiers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211MDRGTEP | Lower 1.1 nV/√Hz noise, but only ±18 V max supply; SOIC-8 package, not hermetic | Preferred for space-constrained, ultra-low-noise lab equipment; lacks −55°C rating and CDIP reliability | Select when noise dominates over temperature range and hermeticity; avoid for flight-critical or outdoor metering |
| AD8675ARZ | Higher 2.8 nV/√Hz noise, ±16.5 V max supply, 10 µV max VIO; SOIC-8, commercial temp range only | Suitable for industrial DMMs and test gear where cost and availability outweigh extreme environmental needs | Choose for high-volume production with RoHS-compliant assembly; not qualified for aerospace or utility metering |
Compared with OPA211MDRGTEP and AD8675ARZ, the TLE2071AMJGB uniquely combines military-grade temperature range, hermetic packaging, rail-to-rail input, and Zener-trimmed offset - making it irreplaceable in flight control and revenue-grade metering where long-term drift and environmental resilience are non-negotiable.

FAQ
What is the maximum supply voltage for TLE2071AMJGB?
The TLE2071AMJGB supports a maximum supply voltage of ±19 V, as specified in its Absolute Maximum Ratings table. This wide supply range allows direct interfacing with legacy ±15 V industrial systems and high-dynamic-range sensor signal chains. Operation beyond ±19 V risks permanent damage; derating is recommended for sustained high-temperature use.
Does TLE2071AMJGB require external offset nulling in precision applications?
Yes - the TLE2071AMJGB includes dedicated Offset Null pins (1 and 5) for manual trimming using a 10 kΩ potentiometer. While its typical input offset is ±300 µV, applications demanding <50 µV residual offset - such as Class 0.1 electricity meters - require this adjustment. The internal Zener trimming sets baseline accuracy; external nulling achieves final system-level calibration.
Is TLE2071AMJGB pin-compatible with standard SOIC-8 op-amps like TL071?
No - TLE2071AMJGB uses a ceramic DIP-8 (JG) package with 0.3 inch lead spacing and offset null pins, whereas TL071 in SOIC-8 has 1.27 mm pitch and no null pins. Pin functions differ: Pin 1 and 5 are offset null terminals (not NC or shutdown), and Pin 8 is NC (not power or enable). PCB layout and footprint are incompatible.
What is the thermal resistance (θJA) of the TLE2071AMJGB package?
The TLE2071AMJGB in the JG (ceramic DIP-8) package has a junction-to-ambient thermal resistance (θJA) of 14.5°C/W, per TI's SLOS181D datasheet Section 6.1. This value assumes standard JEDEC 2S2P test board conditions. For conduction-cooled applications, its θJC is 14.5°C/W - enabling predictable junction temperature estimation in sealed avionics enclosures with controlled airflow.
Can TLE2071AMJGB drive a 600 Ω load at ±10 V output swing?
Yes - the TLE2071AMJGB delivers ±11.5 V output swing into 20 mA load (equivalent to 550 Ω) at ±15 V supplies, and ±13.5 V into 2 mA (7.5 kΩ). At ±10 V output, it comfortably drives 600 Ω with <0.0032% THD+N and full 32 V/µs slew rate, as verified in its Operating Characteristics tables for RL = 600 Ω and VO = ±10 V conditions.
