Product details
Overview
TLE2072QDRG4Q1 from Texas Instruments is a dual-channel, JFET-input operational amplifier qualified for automotive applications (−40°C to 125°C), featuring 10 MHz unity-gain bandwidth, 45 V/µs slew rate, 17 nV/√Hz maximum input voltage noise, ±19 V supply rails, and 6 mV maximum input offset voltage at 25°C.
For engineers reviewing the TLE2072QDRG4Q1 datasheet, TLE2072QDRG4Q1 pinout, TLE2072QDRG4Q1 application, or TLE2072QDRG4Q1 equivalent, this device serves as a direct performance upgrade to TL072 and TL082 in noise-sensitive, high-speed analog signal conditioning, sensor interfacing, and automotive audio front-ends where wide dynamic range and low distortion are critical.
Technical Context
The TLE2072QDRG4Q1 uses TI's Excalibur BiFET process to combine JFET-input stage high impedance (>10¹² Ω) with bipolar output drive capability, enabling robust interfacing with high-impedance sensors while delivering ±80 mA output current. Its architecture ensures stable operation with 56° phase margin at unity gain and supports both dual-supply (±2.25 V to ±19 V) and single-supply configurations using external biasing.
It features on-chip zener trimming for improved DC accuracy, guaranteed maximum noise floor (17 nV/√Hz), and crosstalk attenuation of 120 dB between channels-critical for dual-channel precision instrumentation and differential signal processing in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - enables wide dynamic signal swing up to ±13.3 V output at ±15 V supplies, supporting high-voltage sensor interfaces. |
| Unity-Gain Bandwidth | 9.4 MHz - supports stable closed-loop operation up to ~1 MHz with gain ≥10, suitable for active filters and broadband amplification. |
| Slew Rate | 45 V/µs - ensures faithful reproduction of fast transients (e.g., ultrasonic signals or pulse-shaped sensor outputs) without slew-induced distortion. |
| Input Voltage Noise | 17 nV/√Hz (max) - reduces contribution to system noise floor in low-level signal chains such as piezoelectric or thermocouple amplifiers. |
| Input Offset Voltage | 6 mV (max at 25°C) - defines worst-case DC error in precision gain stages; trimmed version TLE2072AQDRQ1 offers 3.5 mV max for tighter DC specs. |
| Crosstalk Attenuation | 120 dB - prevents inter-channel coupling in dual-channel applications like stereo audio preamps or differential ADC drivers. |
| Operating Temperature | −40°C to 125°C - meets AEC-Q100 Grade 1 requirements for under-hood and powertrain control module deployment. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output node for first op-amp; drives loads up to ±80 mA with rail-to-rail swing limited by supply and load. |
| 2 | Channel 1 Inverting Input | Inverting input terminal; high-impedance JFET node (≥10¹² Ω) minimizes loading on feedback networks and sensors. |
| 3 | Channel 1 Non-Inverting Input | Non-inverting input terminal; same high-impedance characteristic as Pin 2, used for unity-gain buffers or non-inverting amplifiers. |
| 4 | Negative Supply (VCC−) | Ground reference for negative rail; must be connected to system VEE or GND in single-supply designs with virtual ground. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Lower bandwidth (3 MHz), slower slew rate (13 V/µs), higher noise (18 nV/√Hz typ), no automotive qualification. | General-purpose industrial/commercial use only; unsuitable for AEC-Q100-requiring automotive ECUs or ADAS. | Select when cost is primary constraint and temperature range ≤85°C suffices; not drop-in due to lower AC performance. |
| OPA2134UA | Lower noise (8 nV/√Hz), wider bandwidth (8 MHz), but narrower supply range (±18 V max) and no AEC-Q100 certification. | High-end audio and test equipment; lacks automotive reliability validation and extended temperature support. | Prefer for ultra-low-noise audio applications; avoid in automotive deployments requiring long-term under-hood reliability. |
Compared with TL072CDR and OPA2134UA, the TLE2072QDRG4Q1 uniquely delivers automotive-grade reliability, 3× higher slew rate than TL072, and guaranteed low-noise performance across −40°C to 125°C-making it the only option qualified for safety-critical vehicle subsystems requiring both speed and ruggedness.

FAQ
What is the maximum supply voltage for the TLE2072QDRG4Q1?
The TLE2072QDRG4Q1 supports a maximum supply voltage of ±19 V across VCC+ and VCC− terminals. This allows operation with wider dynamic range than standard ±15 V op-amps, enabling direct interfacing with high-output transducers and reducing need for external level-shifting circuitry in automotive sensor front-ends. Exceeding ±19 V risks permanent damage per absolute maximum ratings.
Does the TLE2072QDRG4Q1 require external compensation for stability?
No, the TLE2072QDRG4Q1 is internally compensated and stable for unity-gain configurations. Its phase margin is specified at 56° under standard test conditions (RL = 2 kΩ, CL = 25 pF), supporting stable operation in inverting/non-inverting amplifiers, active filters, and voltage followers without added compensation components-reducing bill-of-materials and layout complexity in space-constrained automotive modules.
How does the TLE2072QDRG4Q1 compare to the TL072 in automotive applications?
The TLE2072QDRG4Q1 is a direct automotive-qualified upgrade to the TL072, offering 3× higher slew rate (45 V/µs vs. 13 V/µs), 2× greater bandwidth (10 MHz vs. 3 MHz), lower guaranteed noise (17 nV/√Hz max vs. unspecified), and AEC-Q100 Grade 1 qualification (−40°C to 125°C). Unlike the TL072, the TLE2072QDRG4Q1 also features on-chip offset trimming and wider ±19 V supply capability-making it suitable for modern automotive ECU designs where performance and reliability are co-required.
Can the TLE2072QDRG4Q1 operate from a single supply?
Yes, the TLE2072QDRG4Q1 can operate from a single supply, but requires proper DC biasing: inputs must remain within the common-mode voltage range (e.g., −0.8 V to 4.2 V at ±5 V equiv), and outputs must be referenced to a virtual ground (e.g., using TI's TLE2426). The device does not feature rail-to-rail input or output, so single-supply designs need careful level-shifting and termination to mid-supply to avoid clipping or phase reversal-common in automotive cabin microphone preamps.
What is the input bias current specification for the TLE2072QDRG4Q1?
The TLE2072QDRG4Q1 has a maximum input bias current of 60 nA across the full temperature range (−40°C to 125°C), with typical values of 15–20 pA at 25°C. This ultra-low bias current-enabled by its JFET input stage-minimizes voltage errors in high-impedance sensor interfaces (e.g., pH electrodes or piezoelectric elements), preserving signal fidelity without requiring guard traces or active bias cancellation networks in PCB layout.
