Product details
Overview
TLE2072AQDRG4Q1 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), and 17 nV/√Hz maximum input voltage noise. It features on-chip offset voltage trimming (3.5 mV max at 25°C), ±19 V supply capability, and pin compatibility with TL072/TL082 for noise-sensitive analog signal conditioning in engine control units and battery management systems.
For engineers reviewing the TLE2072AQDRG4Q1 datasheet, TLE2072AQDRG4Q1 pinout, TLE2072AQDRG4Q1 application, or TLE2072AQDRG4Q1 equivalent, key selection criteria include guaranteed low-noise performance across −40°C to 125°C, high slew rate under ±15 V operation, dual-channel crosstalk attenuation of 120 dB, and SOIC-8 packaging optimized for automotive PCB layouts with thermal resistance of 126°C/W.
Technical Context
The TLE2072AQDRG4Q1 uses TI's Excalibur BiFET process to combine JFET-input stage high impedance (>10¹² Ω) with bipolar output drive (±80 mA), enabling direct interface with high-impedance sensors while maintaining robust dynamic signal range. Its architecture includes zener-based on-chip offset trimming and internal compensation for stable unity-gain operation.
It is fully specified over ±5 V and ±15 V supplies, with common-mode input range extending to ±10.8 V at ±15 V rails and output swing within 1.4 V of rails at ±20 mA load. The device supports dual-supply operation only and requires external biasing for single-supply use.

Pinout & Package
Package: SOIC-8 (D package), surface-mount, 126°C/W thermal resistance, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - Drives loads up to ±80 mA; requires decoupling near VCC+ and VCC− for stability. |

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 (18 nV/√Hz typ), no AEC-Q100 qualification, 10 mV VIO max | Consumer/industrial only; unsuitable for under-hood automotive use due to temperature and reliability limits | Select when cost is primary constraint and automotive qualification is not required |
| OPA2134UA | Higher precision (0.5 mV VIO max), lower noise (8 nV/√Hz), but narrower supply (±18 V max) and no AEC-Q100 | Audio and test equipment; lacks automotive stress testing and extended temperature validation | Select for ultra-low-noise lab-grade instrumentation where AEC-Q100 is irrelevant |
Compared with TL072CDR and OPA2134UA, the TLE2072AQDRG4Q1 uniquely delivers automotive-grade reliability, guaranteed 10 MHz bandwidth, and 45 V/µs slew rate in a pin-compatible SOIC-8 package-making it the only option qualified for safety-critical powertrain signal chains.

FAQ
What is the maximum operating junction temperature for the TLE2072AQDRG4Q1?
The TLE2072AQDRG4Q1 has a maximum junction temperature of 150°C, validated across its full −40°C to +125°C ambient operating range. This rating is supported by thermal characterization in the SOIC-8 package (θJA = 126°C/W) and is critical for under-hood placement in engine control modules where ambient temperatures exceed 105°C. The device incorporates thermal shutdown protection to prevent permanent damage during sustained overload conditions.
Does the TLE2072AQDRG4Q1 support single-supply operation?
No, the TLE2072AQDRG4Q1 is designed exclusively for dual-supply operation. Its common-mode input range and output swing are specified relative to symmetric rails (e.g., ±5 V or ±15 V), and it lacks rail-to-rail input/output architecture. For single-supply applications, TI recommends using the TLE2426 virtual ground generator or migrating to LinCMOS families like TLC27L2, as explicitly stated in the datasheet's application guidance section.
How does the TLE2072AQDRG4Q1 compare to the TL072 in terms of noise performance?
The TLE2072AQDRG4Q1 guarantees a maximum input voltage noise of 17 nV/√Hz at 10 kHz, compared to the TL072's typical 18 nV/√Hz with no maximum specification. More critically, the TLE2072AQDRG4Q1 achieves a typical noise floor of 11.6 nV/√Hz-30% lower than the TL072's typical 16 nV/√Hz-enabling measurable SNR improvement in low-amplitude sensor interfaces such as knock detection and MEMS microphones.
Is the TLE2072AQDRG4Q1 pin-compatible with the TL082?
Yes, the TLE2072AQDRG4Q1 uses the same SOIC-8 (D) package and identical pinout as the TL082, TL072, and TL052. This allows direct drop-in replacement in existing PCB layouts without modification, delivering immediate improvements in bandwidth (2×), slew rate (3×), and noise floor while maintaining functional compatibility in standard inverting/non-inverting configurations.
What is the supply current consumption of the TLE2072AQDRG4Q1 at ±15 V?
At ±15 V supply and 25°C, the TLE2072AQDRG4Q1 draws 2.7 mA (typical) to 3.6 mA (max) total supply current for both channels under no-load conditions. This value remains stable across the full −40°C to +125°C operating range, with the maximum specified as 3.6 mA. The current draw increases linearly with output loading but stays within 160 mA total per supply rail, as defined in absolute maximum ratings.
