Product details
Overview
TLE2072AQDRQ1 from Texas Instruments is a dual-channel, automotive-qualified JFET-input operational amplifier optimized for low-noise, high-speed signal conditioning in harsh environments. It delivers 10 MHz unity-gain bandwidth, 45 V/µs slew rate (±15 V), 17 nV/√Hz maximum input voltage noise, ±19 V supply capability, and 3.5 mV max input offset voltage at −40°C to 125°C - enabling precision analog front-ends in engine control units and battery management systems.
For engineers reviewing the TLE2072AQDRQ1 datasheet, TLE2072AQDRQ1 pinout, TLE2072AQDRQ1 application, or TLE2072AQDRQ1 equivalent, key selection criteria include its guaranteed low-noise performance across temperature, rail-to-rail output swing compatibility with ±15 V supplies, automotive AEC-Q100 Grade 1 qualification, and pin compatibility with legacy TL072/TL082 designs requiring bandwidth and slew-rate upgrades.
Technical Context
The TLE2072AQDRQ1 employs Texas Instruments' 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 under capacitive loads up to 100 pF while maintaining ≥56° phase margin at unity gain.
It is fully specified over ±5 V and ±15 V dual supplies, with common-mode input range extending to within 1.9 V of rails at ±5 V and 11.9 V at ±15 V. The device supports dc-coupled configurations via on-chip zener trimming for offset voltage accuracy and includes crosstalk attenuation >120 dB between channels - critical for multi-sensor signal chains in automotive ADAS subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - enables wide dynamic signal range in high-voltage automotive sensors without external level-shifting. |
| Unity-Gain Bandwidth | 9.4 MHz (typ, ±5 V) - supports accurate amplification of ultrasonic sensor echoes and motor phase currents up to ~1 MHz. |
| Slew Rate | 45 V/µs (max, ±15 V) - ensures faithful reproduction of fast transients in ignition coil drivers and active filter stages. |
| Input Voltage Noise | 17 nV/√Hz (ensured max, f = 10 kHz) - guarantees low-noise performance in microphone preamps and strain-gauge bridges. |
| Input Offset Voltage | 3.5 mV (max, −40°C to 125°C) - provides predictable dc accuracy for closed-loop current sensing in 48 V mild-hybrid systems. |
| Crosstalk Attenuation | 120 dB (typ) - prevents channel coupling in dual-channel applications like differential encoder interfaces or stereo audio paths. |
| Output Current Drive | ±80 mA (each channel) - allows direct driving of 600 Ω loads or multiple downstream op-amp inputs without buffering. |

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 |
|---|---|---|---|
| TL072QDRQ1 | Lower bandwidth (3 MHz), slower slew rate (13 V/µs), higher noise (25 nV/√Hz typ), no AEC-Q100 qualification. | Cost-sensitive non-safety-critical cabin electronics only; unsuitable for powertrain or ADAS due to unqualified temp range and performance limits. | Select only if design tolerates 3× lower bandwidth and lacks automotive qualification requirements. |
| OPA2134UA | Fully specified for ±15 V, 8 MHz bandwidth, 20 V/µs slew rate, 8 nV/√Hz noise, but not AEC-Q100 qualified and rated only to 85°C. | High-fidelity audio or industrial test equipment where automotive reliability is not required. | Choose when ultra-low noise dominates over automotive qualification and extended temperature operation. |
Compared with TL072QDRQ1 and OPA2134UA, the TLE2072AQDRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 10 MHz bandwidth, and guaranteed 17 nV/√Hz noise - making it the only option qualified for safety-critical automotive signal conditioning where both performance and reliability are mandatory.

FAQ
What is the maximum supply voltage rating for the TLE2072AQDRQ1?
The TLE2072AQDRQ1 supports supply voltages up to ±19 V, as confirmed in the Absolute Maximum Ratings table. This allows operation with extended rail ranges beyond standard ±15 V, enabling direct interfacing with high-voltage automotive sensors and actuators without external regulation - a key advantage over TL072-class devices limited to ±15 V.
Is the TLE2072AQDRQ1 pin-compatible with the TL072 or TL082?
Yes, the TLE2072AQDRQ1 uses the same SOIC-8 (D) package and identical pinout as TL072 and TL082, as shown in the "TLE2072 AND TLE2072A D PACKAGE (TOP VIEW)" diagram. This enables direct drop-in replacement in existing PCB layouts to upgrade bandwidth and slew rate without hardware changes - a documented design benefit emphasized in the datasheet's "Direct Upgrades" section.
What is the guaranteed input voltage noise specification for the TLE2072AQDRQ1?
The TLE2072AQDRQ1 has an ensured maximum input voltage noise of 17 nV/√Hz at 10 kHz, per the Electrical Characteristics tables for both ±5 V and ±15 V operation. This value is explicitly guaranteed across the full −40°C to +125°C temperature range, distinguishing it from typical-only specs found in many competing op-amps.
Does the TLE2072AQDRQ1 support single-supply operation?
The TLE2072AQDRQ1 is designed for dual-supply operation, but can be used in single-supply configurations with proper DC biasing - such as using TI's TLE2426 virtual ground generator to establish a mid-rail reference. Its common-mode input range extends to within 1.9 V of either rail at ±5 V, allowing functional use with appropriate input/output level shifting.
What automotive qualification does the TLE2072AQDRQ1 hold?
The TLE2072AQDRQ1 is qualified to AEC-Q100 Grade 1, meaning it is certified for operation from −40°C to +125°C ambient temperature and has passed stress tests including HTOL, TC, and ESD per automotive reliability standards. This qualification is explicitly stated in the device family title ("TLE207x-Q1") and ordering information table.
