Product details
Overview
TLE2071QDRG4Q1 from Texas Instruments is an automotive-qualified, low-noise, high-speed JFET-input operational amplifier in SOIC-8 package. It delivers 10 MHz unity-gain bandwidth, 45 V/µs slew rate, and 17 nV/√Hz maximum input voltage noise - doubling bandwidth and tripling slew rate versus TL07x. It operates from ±2.25 V to ±19 V supplies and is used in precision sensor signal conditioning for automotive engine control units.
For engineers reviewing the TLE2071QDRG4Q1 datasheet, TLE2071QDRG4Q1 pinout, TLE2071QDRG4Q1 application, or TLE2071QDRG4Q1 equivalent, key selection criteria include guaranteed low-noise performance (≤17 nV/√Hz), wide supply range (±19 V), offset voltage trimming (4 mV max at 25°C), and AEC-Q100 Grade 1 qualification for under-hood automotive use.
Technical Context
The TLE2071QDRG4Q1 uses TI's Excalibur BiFET process to combine JFET-input stage advantages - ultra-high input impedance (>10¹² Ω) and low input bias current (≤175 pA) - with bipolar output drive capability (±80 mA). Its architecture ensures stable operation up to 10 MHz with 56° phase margin at unity gain when loaded with 2 kΩ || 25 pF.
It features on-chip zener trimming for improved DC accuracy (4 mV max VIO at 25°C, 9 mV over −40°C to 125°C), rail-to-rail common-mode input range (−10.9 V to +15 V at ±15 V supplies), and robust absolute maximum ratings including ±19 V supply rails and 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - supports wide dynamic signal range in high-voltage automotive sensors and industrial analog front-ends. |
| Unity-Gain Bandwidth | 9.4 MHz (typical at ±5 V) - enables stable closed-loop operation in high-frequency active filters and fast-settling instrumentation amplifiers. |
| Slew Rate | 45 V/µs (positive), 40 V/µs (negative) at ±15 V - supports clean reproduction of fast transient signals without distortion in motor control feedback paths. |
| Input Voltage Noise | 17 nV/√Hz (ensured maximum at 10 kHz) - critical for low-level signal integrity in oxygen sensor or knock detection circuits. |
| Input Offset Voltage | 4 mV max at 25°C, 9 mV max over full temperature range - enables accurate DC-coupled amplification without external nulling in ECU analog inputs. |
| Common-Mode Input Range | −10.9 V to +15 V at ±15 V supply - accommodates biased sensor outputs directly without level-shifting in battery monitoring systems. |
| Output Current Drive | ±80 mA - sufficient to drive low-impedance loads like 600 Ω transmission lines or capacitive DAC buffers without external buffering. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150°C rated, JEDEC MS-012AC compliant. Thermal resistance θJA = 126°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OFFSET N1) | Offset null adjustment terminal | Connects to external potentiometer for fine-tuning input offset voltage - available only on TLE2071 variants, not on dual/quad versions. |
| 2 (IN−) | Inverting input | High-impedance JFET node (≥10¹² Ω); requires guarding in PCB layout to minimize leakage-induced drift in precision applications. |
| 3 (IN+) | Non-inverting input | Matches IN− in impedance and noise; differential input voltage range extends rail-to-rail (VCC− to VCC+). |
| 4 (VCC−) | Negative supply rail | Must be connected to system ground or negative supply; supports operation down to −19 V - essential for bipolar sensor interfaces. |
| 5 (NC) | No internal connection | Unbonded pad; must remain unconnected and unstubbed to avoid parasitic coupling or thermal stress. |
| 6 (VCC+) | Positive supply rail | Accepts up to +19 V; decoupling capacitor (0.1 µF ceramic + 10 µF tantalum) required within 5 mm for stability. |
| 7 (OUT) | Amplifier output | Capable of ±80 mA short-circuit current; drives capacitive loads ≤100 pF directly; larger loads require isolation resistor. |
| 8 (OFFSET N2) | Offset null adjustment terminal | Paired with Pin 1 for symmetric nulling; unused pins must be left floating or tied together with a 10 kΩ potentiometer wiper. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C ambient), qualified for engine control, transmission, and body electronics. |
| Low-noise architecture | 11.6 nV/√Hz typical (17 nV/√Hz max) at 10 kHz - reduces integrated noise in 10 Hz–100 kHz sensor bandwidths by >3× vs TL072. |
| On-chip offset trimming | Zener-diode trimming achieves 4 mV max VIO at 25°C - eliminates need for external nulling circuitry in production ECU designs. |
| Wide supply capability | Operates from ±2.25 V to ±19 V - supports legacy 15 V systems and modern 12 V battery-referenced architectures without level-shifting. |
| Pin-compatible upgrade | Direct replacement for TL071, TL081, and TL051 in existing SOIC-8 layouts - enables performance uplift without PCB revision. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CDR | Lower bandwidth (3 MHz), higher noise (25 nV/√Hz), no AEC-Q100 qualification, 10 mV VIO max. | General-purpose industrial/commercial use only; unsuitable for automotive under-hood environments. | Select only for cost-sensitive non-automotive designs where 10 MHz bandwidth and 17 nV/√Hz noise are not required. |
| OPA1611AIDR | Lower noise (1.1 nV/√Hz), lower IB (1.5 pA), but narrower supply range (±2.25 V to ±18 V), no AEC-Q100 Grade 1 rating. | High-fidelity audio or test equipment; lacks automotive qualification and wider ±19 V rail support. | Prefer for ultra-low-noise lab-grade systems; avoid where AEC-Q100 compliance or ±19 V operation is mandatory. |
Compared with TL071CDR and OPA1611AIDR, the TLE2071QDRG4Q1 uniquely balances automotive qualification, 10 MHz bandwidth, ±19 V supply tolerance, and guaranteed low-noise performance - making it the only drop-in solution for upgrading legacy BiFET-based ECU signal chains.

FAQ
What is the maximum supply voltage rating for the TLE2071QDRG4Q1?
The TLE2071QDRG4Q1 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 in high-dynamic-range automotive systems such as 12 V battery-referenced engine control units where transient spikes exceed nominal rails. Operation beyond these limits risks permanent damage.
Is the TLE2071QDRG4Q1 pin-compatible with the TL071 series?
Yes, the TLE2071QDRG4Q1 is fully pin-compatible with TL071, TL081, and TL051 in the SOIC-8 (D) package. All eight pins - including OFFSET N1/N2, IN−, IN+, VCC−, VCC+, and OUT - match identically. This enables direct drop-in replacement in existing PCB layouts to upgrade bandwidth, slew rate, and noise performance without redesign.
Does the TLE2071QDRG4Q1 support single-supply operation?
The TLE2071QDRG4Q1 is designed for dual-supply operation but can function in single-supply configurations with proper DC biasing. Its common-mode input range extends to within 0.8 V of the negative rail and 1.9 V below the positive rail at ±5 V supplies - so with a 10 V single supply, a virtual ground at 5 V (e.g., using TI's TLE2426) is required to maintain linear operation and avoid clipping.
What is the guaranteed input offset voltage specification for the TLE2071QDRG4Q1 over temperature?
The TLE2071QDRG4Q1 guarantees a maximum input offset voltage of 9 mV over its full operating temperature range of −40°C to +125°C. At 25°C, the limit is tighter: 4 mV max. This is achieved via on-chip zener trimming and ensures predictable DC accuracy in automotive sensor interfaces without external calibration.
How does the noise performance of the TLE2071QDRG4Q1 compare to standard TL071 devices?
The TLE2071QDRG4Q1 delivers 17 nV/√Hz maximum input voltage noise at 10 kHz - a 3× improvement over the TL071's typical 50 nV/√Hz. Its Excalibur process achieves 11.6 nV/√Hz typical, enabling significantly better signal integrity in low-level sensor applications such as knock detection or oxygen sensing where noise directly impacts diagnostic resolution.
