Product details
Overview
TLE2071AQDRQ1 from Texas Instruments is an automotive-qualified, low-noise, high-speed JFET-input operational amplifier with 10 MHz unity-gain bandwidth, 45 V/µs slew rate, and 17 nV/√Hz maximum input voltage noise. It operates from ±2.25 V to ±19 V supplies, features on-chip offset voltage trimming (2 mV max at 25°C), and serves as a direct upgrade to TL07x/TL08x in precision analog front-ends for engine control units and battery monitoring systems.
For engineers reviewing the TLE2071AQDRQ1 datasheet, TLE2071AQDRQ1 pinout, TLE2071AQDRQ1 application, or TLE2071AQDRQ1 equivalent, key selection criteria include its A-grade offset voltage specification, guaranteed noise floor, extended supply range, and SOIC-8 automotive qualification per AEC-Q100 Grade 1 (−40°C to 125°C).
Technical Context
The TLE2071AQDRQ1 uses TI's Excalibur BiFET process to combine JFET-input stage high impedance (>10¹² Ω) with bipolar output drive capability (±80 mA). Its architecture ensures stable operation with phase margin of 56° at unity gain and supports both dual-supply (±5 V, ±15 V) and single-supply configurations when paired with virtual ground circuitry like the TLE2426.
It delivers enhanced AC performance over legacy BiFET op-amps: >2× bandwidth and 3× slew rate versus TL07x, while maintaining DC precision via zener-trimmed input offset. Input common-mode range extends to within 0.8 V of rails at ±5 V and ±10.9 V at ±15 V, enabling wide dynamic signal handling in automotive sensor interfaces.
Key Specifications

FAQ
What is the maximum supply voltage rating for the TLE2071AQDRQ1?
The TLE2071AQDRQ1 has absolute maximum supply ratings of ±19 V. Operation beyond this risks permanent damage. Recommended operating range is ±2.25 V to ±19 V, supporting both 12 V and 24 V automotive systems with transient headroom. The device maintains specified performance across this full range, including at ±15 V and ±5 V test conditions documented in its datasheet.
Is the TLE2071AQDRQ1 pin-compatible with standard TL071 op-amps?
Yes, the TLE2071AQDRQ1 uses the same SOIC-8 (D) package and pinout as the TL071, TL081, and TL051 families. Pin 1 (OFFSET N1), pin 5 (NC), and pin 8 (OFFSET N2) are functionally identical-though OFFSET pins are unused in non-A variants, they remain physically present and electrically compatible. This enables drop-in replacement in existing layouts without PCB changes.
How does the TLE2071AQDRQ1 achieve its low input voltage noise of 17 nV/√Hz?
The TLE2071AQDRQ1 achieves its guaranteed 17 nV/√Hz maximum input voltage noise through TI's Excalibur JFET-input process, which optimizes channel geometry and biasing to minimize thermal and flicker noise. The 11.6 nV/√Hz typical value at 10 kHz reflects intrinsic device physics-not external filtering-and is validated across temperature and process corners per AEC-Q100 stress testing protocols.
Does the TLE2071AQDRQ1 support single-supply operation?
Yes, the TLE2071AQDRQ1 can operate from a single supply when the input common-mode and output swing ranges are respected. For example, with +10 V and GND, inputs must stay between −0.8 V and +9.2 V (per ±5 V data), and output swings to ~1.4 V above GND and ~8.6 V below VCC. Use of TI's TLE2426 virtual ground generator is recommended to establish mid-rail bias for true AC-coupled operation.
What is the significance of the "A" suffix in TLE2071AQDRQ1?
The "A" in TLE2071AQDRQ1 denotes the precision grade: maximum input offset voltage of 2 mV at 25°C (vs. 4 mV for the standard TLE2071QDRQ1). This tighter specification is achieved via on-chip zener trimming during final test and is fully characterized across −40°C to 125°C. The "A" grade is essential for DC-critical applications like current sensing and thermocouple amplification where initial offset directly impacts accuracy.
