Product details
Overview
TL072QDREP from Texas Instruments is a radiation-hardened, extended-temperature JFET-input dual operational amplifier optimized for high-fidelity audio preamplification and precision analog signal conditioning in defense, aerospace, and medical systems. It delivers 13 V/μs slew rate, 18 nV/√Hz input voltage noise at 1 kHz, 3 MHz unity-gain bandwidth, ±12 V maximum output swing (RL ≥ 2 kΩ), and operates across –40°C to 125°C.
For engineers reviewing the TL072QDREP datasheet, TL072QDREP pinout, TL072QDREP application, or TL072QDREP equivalent, key selection criteria include low-noise JFET input stage performance, extended temperature reliability, SOIC-8 packaging with military-grade traceability, and compatibility with high-impedance sensor interfaces and audio signal chains requiring <0.003% THD.
Technical Context
The TL072QDREP integrates two independent JFET-input op-amps on a single monolithic die, each featuring high-impedance (>10¹² Ω) inputs, internal frequency compensation, and bipolar output stages. Its architecture supports rail-to-rail common-mode input range extending to VCC+, enabling operation with single-ended or split supplies up to ±15 V.
Designed for mission-critical environments, it includes output short-circuit protection, latch-up-free operation, and controlled baseline manufacturing with full product traceability. Electrical specifications are fully characterized over –40°C to 125°C, with input offset voltage ≤6 mV and supply current per amplifier ≤2.5 mA at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±15 V max - supports wide dynamic range signal processing without clipping in ±12 V systems |
| Slew Rate | 13 V/μs typ - enables faithful reproduction of fast transients in audio and instrumentation signals |
| Input Noise Voltage | 18 nV/√Hz @ 1 kHz - critical for low-level sensor amplification where signal integrity dominates SNR |
| Unity-Gain Bandwidth | 3 MHz - sufficient for audio band (20 Hz–20 kHz) with ample phase margin and stability |
| Input Bias Current | 65 pA typ @ 25°C - preserves accuracy in high-impedance photodiode or piezoelectric sensor interfaces |
| Total Harmonic Distortion | 0.003% typ @ 1 kHz - meets high-fidelity audio preamp requirements per IEC 60268 |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, avionics, and industrial control environments |
Pinout & Package
TL072QDREP is housed in an 8-pin SOIC (D) package with 1.27 mm pitch, 3.91 mm body width, and 1.75 mm max height - compatible with standard surface-mount assembly and IPC-7351 land patterns.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance JFET node accepting negative feedback or signal inversion |
| 2 | Non-Inverting Input (Amplifier A) | High-Z JFET node for reference or positive signal injection |
| 3 | Output (Amplifier A) | Class-AB bipolar output stage capable of ±12 V swing into 2 kΩ load |
| 4 | VCC− | Negative supply rail connection - must be decoupled locally with 0.1 μF ceramic capacitor |
| 5 | VCC+ | Positive supply rail connection - shared bias for both amplifiers; requires local decoupling |
| 6 | Non-Inverting Input (Amplifier B) | Independent high-Z input for second channel; electrically isolated from Amplifier A |
| 7 | Inverting Input (Amplifier B) | Second amplifier's feedback node - identical electrical characteristics to Pin 1 |
| 8 | Output (Amplifier B) | Second independent output - no crosstalk (<120 dB attenuation) between channels |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | 65 pA typ enables stable DC coupling in pH meters and strain gauge bridges without drift |
| High Common-Mode Range | Includes VCC+ - allows direct interface to sensors operating near positive rail (e.g., current-sense amps) |
| Output Short-Circuit Protection | Unlimited duration rating prevents failure during board-level fault conditions or test shorts |
| Latch-Up Free Operation | Guaranteed immunity to CMOS-like parasitic thyristor triggering in harsh ESD or transient environments |
| Controlled Baseline Manufacturing | Single fab/assembly/test site ensures consistent parametric distribution and long-term supply continuity |

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 | Commercial-grade (0°C to 70°C), no extended temp qualification or defense traceability | Not suitable for aerospace/medical use; lacks V62/12604-01XE military pedigree | Select only for cost-sensitive non-critical industrial prototypes |
| OPA2134UA | Lower noise (8 nV/√Hz), higher slew rate (20 V/μs), but ±18 V max supply vs. TL072QDREP's ±15 V | Superior audio performance but unqualified for extended temperature or defense applications | Prefer for studio-grade audio where extended temp is not required |
Compared with TL072CDR and OPA2134UA, TL072QDREP uniquely combines JFET-input low-noise performance with extended temperature operation, radiation-hardened process controls, and full defense-grade traceability - making it irreplaceable in certified safety-critical systems where commercial alternatives lack qualification evidence.

FAQ
What is the maximum supply voltage for TL072QDREP?
The absolute maximum supply voltage for TL072QDREP is ±18 V, but recommended operating conditions specify ±15 V. Exceeding ±15 V risks exceeding thermal limits and degrading long-term reliability, especially at high ambient temperatures. The device is fully characterized and guaranteed to meet all specifications within ±15 V at –40°C to 125°C.
Does TL072QDREP support rail-to-rail input operation?
TL072QDREP supports common-mode input voltage range extending to VCC+, meaning its inputs operate up to the positive supply rail - a key advantage over many bipolar-input op-amps. However, it does not support rail-to-rail output swing; maximum peak output is ±12 V into 2 kΩ. This makes it ideal for single-supply sensor interfaces where the signal sits near VCC+.
Is TL072QDREP pin-compatible with standard TL072 variants?
Yes, TL072QDREP uses the industry-standard SOIC-8 (D) package with identical pinout to TL072CDR, TL072IDR, and TL072CP. All share Pin 1 (Inverting Input A), Pin 2 (Non-Inverting Input A), Pin 3 (Output A), Pin 4 (VCC−), Pin 5 (VCC+), Pin 6 (Non-Inverting Input B), Pin 7 (Inverting Input B), and Pin 8 (Output B).
What is the input offset voltage specification for TL072QDREP?
TL072QDREP has a maximum input offset voltage of 6 mV at 25°C, as specified in the ordering information table. Over full temperature range (–40°C to 125°C), the typical offset drift is 18 μV/°C. This level of precision is sufficient for most audio and industrial signal conditioning tasks, though not suited for microvolt-level DC measurements without external trimming.
How does TL072QDREP differ from TL072MDREP?
TL072QDREP is qualified for –40°C to 125°C operation and carries the V62/12604-01XE military specification, while TL072MDREP is rated for –55°C to 125°C and carries V62/12604-02XE. Both share identical electrical specs and SOIC-8 packaging, but TL072MDREP targets colder military environments and undergoes additional screening for extreme low-temperature reliability.
