Product details
Overview
TLE2072QDRQ1 from Texas Instruments is an automotive-qualified dual JFET-input operational amplifier with 10 MHz unity-gain bandwidth, 45 V/µs slew rate (±15 V supply), and 17 nV/√Hz maximum input voltage noise. It features ±19 V supply rails, on-chip offset voltage trimming (6 mV max at 25°C), and operates across −40°C to +125°C for engine control, battery monitoring, and sensor signal conditioning in harsh environments.
For engineers reviewing the TLE2072QDRQ1 datasheet, TLE2072QDRQ1 pinout, TLE2072QDRQ1 application, or TLE2072QDRQ1 equivalent, key selection criteria include its low-noise JFET input stage, guaranteed noise floor, wide common-mode range (−11 V to +11 V at ±15 V), crosstalk attenuation of 120 dB, and direct pin compatibility with TL072/TL082 for performance upgrades in automotive analog front-ends.
Technical Context
The TLE2072QDRQ1 uses TI's Excalibur BiFET process to combine high-input-impedance JFET inputs with bipolar output drive, enabling precise amplification of high-impedance sensor signals without sacrificing dynamic response. Its architecture ensures stable operation with ≥56° phase margin and supports both dual-supply (±2.25 V to ±19 V) and single-supply configurations when biased via virtual ground.
It delivers 120 dB crosstalk attenuation between channels, ensuring channel isolation critical for multi-sensor systems. The device is fully specified over temperature and supply voltage, with guaranteed maximum input offset voltage (10 mV full-range), input bias current (60 nA), and noise (17 nV/√Hz), making it suitable for precision automotive signal chains where long-term DC stability and AC fidelity are co-required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - Enables wide dynamic signal range up to ±13.3 V output swing at ±15 V supply, supporting high-voltage sensor interfaces. |
| Unity-Gain Bandwidth | 9.4 MHz (typical, ±5 V) - Supports fast transient response in active filters and motor control feedback loops. |
| Slew Rate | 45 V/µs (positive, ±15 V) - Ensures faithful reproduction of fast-rising signals like crankshaft position pulses. |
| Input Voltage Noise | 17 nV/√Hz (max, 10 kHz) - Critical for low-level thermocouple or strain gauge amplification without added noise floor degradation. |
| Input Offset Voltage | 6 mV (max at 25°C), 10 mV (max over −40°C to +125°C) - Enables accurate DC-coupled measurements in battery voltage monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), higher noise (25 nV/√Hz typ), no AEC-Q100 qualification, 10 mV VIO max. | General-purpose industrial use only; unsuitable for safety-critical or extended-temperature automotive deployment. | Select when cost sensitivity outweighs noise, speed, and qualification requirements in non-automotive designs. |
| OPA2134UA | Lower noise (8 nV/√Hz), higher precision (0.5 mV VIO max), but not AEC-Q100 qualified and limited to +125°C ambient. | High-fidelity audio and test equipment; lacks automotive reliability validation and extended cold-temperature operation. | Prefer for premium audio or lab instrumentation where ultra-low noise dominates over automotive compliance. |
Compared with TL072CDR and OPA2134UA, the TLE2072QDRQ1 uniquely balances automotive qualification, 10 MHz bandwidth, and guaranteed low noise-making it the only option among the three validated for under-hood engine control and battery monitoring where temperature, reliability, and signal fidelity are jointly constrained.

FAQ
What is the maximum supply voltage rating for the TLE2072QDRQ1?
The TLE2072QDRQ1 supports supply voltages up to ±19 V, enabling operation with unregulated automotive battery rails and transient-tolerant designs. This rating is absolute maximum; recommended operating range is ±2.25 V to ±19 V per TI SGLS226B datasheet Section 5. Absolute Maximum Ratings.
Does the TLE2072QDRQ1 require external compensation for unity-gain stability?
No, the TLE2072QDRQ1 is internally compensated and stable at unity gain. Its phase margin is guaranteed ≥56° under standard test conditions (VCC = ±15 V, RL = 2 kΩ, CL = 25 pF), as confirmed in the SGLS226B datasheet Section 7.2 Operating Characteristics.
How does the TLE2072QDRQ1 compare to the TL072 in terms of noise performance?
The TLE2072QDRQ1 guarantees ≤17 nV/√Hz input voltage noise (max at 10 kHz), while the TL072 specifies 25 nV/√Hz typical with no maximum guarantee. This 8 nV/√Hz improvement directly enhances signal-to-noise ratio in low-level sensor amplification, especially in engine knock detection and cabin microphones.
Is the TLE2072QDRQ1 pin-compatible with the TL072 and TL082?
Yes, the TLE2072QDRQ1 uses the same SOIC-8 (D) package and identical pinout as TL072 and TL082, enabling direct drop-in replacement in existing PCB layouts without modification-provided supply and layout constraints (e.g., decoupling, grounding) meet the higher-performance requirements of the TLE2072QDRQ1.
What is the guaranteed input offset voltage specification for the TLE2072QDRQ1 over temperature?
The TLE2072QDRQ1 guarantees a maximum input offset voltage of 10 mV across the full operating temperature range of −40°C to +125°C, with tighter 6 mV max at 25°C. This is documented in the SGLS226B datasheet Table 3 (TLE2072-Q1 Electrical Characteristics, Full Range column).
