Product details
Overview
TLE2071AQDRG4Q1 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 features on-chip offset voltage trimming (2 mV max at 25°C), ±19 V supply capability, and pin compatibility with TL07x/TL08x families for drop-in performance upgrades in sensor signal conditioning and audio front-ends.
For engineers reviewing the TLE2071AQDRG4Q1 datasheet, TLE2071AQDRG4Q1 pinout, TLE2071AQDRG4Q1 application, or TLE2071AQDRG4Q1 equivalent, key selection criteria include guaranteed low-noise operation down to 17 nV/√Hz, automotive temperature range (−40°C to 125°C), SOIC-8 packaging, and validated DC precision for dc-coupled transducer interfaces.
Technical Context
The TLE2071AQDRG4Q1 uses TI's Excalibur BiFET process to combine JFET-input high impedance (>10¹² Ω) with bipolar output drive capability, enabling robust interfacing with high-impedance sources like piezoelectric sensors while maintaining fast transient response. Its internal zener trimming ensures tight input offset voltage (2 mV max) across temperature.
Designed for dual-supply operation, it supports common-mode input ranges up to ±10.9 V at ±15 V supplies and delivers rail-to-rail compatible output swing (±13.3 V into 2 mA load). Phase margin is stabilized at 56°–57° across operating conditions, ensuring stable closed-loop performance without external compensation.
Key Specifications

|---|---|
| Unity-Gain Bandwidth | 9.4 MHz - Enables stable amplification of signals up to ~1 MHz with gain ≥10 in high-fidelity analog chains. |
| Slew Rate | 45 V/µs - Supports clean reproduction of fast-rising pulses (e.g., ultrasonic echo bursts) without slew-induced distortion. |
| Input Voltage Noise | 17 nV/√Hz (max) - Ensures minimal added noise in low-level sensor amplification (e.g., microphone preamps, strain gauge bridges). |
| Input Offset Voltage | 2 mV (max at 25°C) - Reduces dc error in precision instrumentation, enabling accurate dc-coupled measurements without manual nulling. |
| Supply Voltage Range | ±2.25 V to ±19 V - Allows flexible biasing in both low-voltage portable systems and high-dynamic-range industrial signal paths. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071QDRQ1 | Lower bandwidth (3 MHz), higher 25°C VIO (10 mV max), no automotive qualification. | Cost-sensitive non-automotive designs where noise <25 nV/√Hz and −40°C operation are not required. | Select when budget constraints outweigh need for low-noise or extended temperature performance. |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), higher quiescent current (3.6 mA), no AEC-Q100 qualification. | High-end audio and precision lab equipment requiring ultra-low noise but not automotive reliability. | Choose for premium audio signal chains where power efficiency and automotive compliance are secondary. |

FAQ
What is the maximum supply voltage rating for TLE2071AQDRG4Q1?
The TLE2071AQDRG4Q1 has an absolute maximum supply voltage rating of ±19 V, meaning VCC+ may reach +19 V and VCC− may reach −19 V relative to ground. This allows operation at ±15 V with 4 V headroom, supporting wide dynamic range in high-fidelity analog circuits without risk of latch-up or damage under normal conditions.
Is TLE2071AQDRG4Q1 pin-compatible with TL071?
Yes, TLE2071AQDRG4Q1 is fully pin-compatible with TL071 in the SOIC-8 (D) package, including identical pin 1 (OFFSET N1), pin 2 (IN−), pin 3 (IN+), pin 4 (VCC−), pin 6 (VCC+), pin 7 (OUT), and pin 8 (OFFSET N2) assignments. This enables direct replacement in existing TL071-based PCB layouts without modification.
Does TLE2071AQDRG4Q1 require external offset nulling?
No - TLE2071AQDRG4Q1 includes on-chip zener trimming that guarantees ≤2 mV input offset voltage at 25°C and ≤7 mV over −40°C to 125°C, eliminating the need for external nulling in most applications. Pins 1 and 8 (OFFSET N1/N2) are provided for optional fine-tuning but are not required for baseline specification compliance.
What is the typical input bias current of TLE2071AQDRG4Q1?
The typical input bias current of TLE2071AQDRG4Q1 is 15 pA at 25°C, with a maximum of 60 nA over the full −40°C to 125°C operating range. This ultra-low bias current preserves signal integrity when driving high-impedance sources such as photodiodes, piezoelectric sensors, or passive RC filters without loading-induced errors.
Can TLE2071AQDRG4Q1 operate from a single supply?
TLE2071AQDRG4Q1 is optimized for dual-supply operation but can be used with single supplies if the input common-mode range and output swing are properly biased - e.g., using TI's TLE2426 virtual ground generator. Its input range extends to within 0.8 V of either rail at ±5 V supplies, enabling rail-sparing configurations in 10 V or 12 V systems.
