Product details
Overview
TLE2024QDWREP from Texas Instruments is a radiation-hardened, quad precision operational amplifier engineered for high-reliability aerospace and defense systems operating across −40°C to 125°C. It delivers 2 MHz unity-gain bandwidth, 0.45 V/μs slew rate, and 1000 μV max input offset voltage at ±15 V supply, enabling low-level signal conditioning in satellite telemetry front-ends and avionics sensor interfaces.
For engineers reviewing the TLE2024QDWREP datasheet, TLE2024QDWREP pinout, TLE2024QDWREP application, or TLE2024QDWREP equivalent, key selection criteria include its extended temperature qualification, phase-reversal protection, low 1.4 mA total supply current (±15 V), and compatibility with single-supply (5 V) or dual-supply (±15 V) configurations in safety-critical analog signal chains.
Technical Context
The TLE2024QDWREP uses Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate than legacy OP21-based designs. Its bias circuit ensures stable dc parameters over time and temperature-critical for long-duration space missions.
It features phase-reversal protection that prevents output inversion when inputs fall below the negative rail, and supports rail-to-rail common-mode input operation down to VCC− (e.g., −15 V), making it suitable for single-ended sensor interfacing in split-supply industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2 V to ±20 V - Supports both 5-V single-supply and ±15-V dual-supply operation without redesign. |
| Unity-Gain Bandwidth | 2 MHz typ at ±15 V - Enables stable closed-loop gain ≥1 amplification up to audio and low-speed data acquisition frequencies. |
| Slew Rate | 0.45 V/μs min at ±15 V - Limits full-power bandwidth to ~71 kHz, sufficient for DC–100 kHz sensor signal conditioning. |
| Input Offset Voltage | 1000 μV max over −40°C to 125°C - Ensures ≤1 mV error in precision 12-bit ADC front-ends with 5 V reference. |
| Supply Current per Amplifier | 350 μA max at ±15 V - Total 1.4 mA quiescent draw enables low-power battery-backed instrumentation. |
| Common-Mode Input Range | Includes VCC− (e.g., −15 V) - Allows direct connection of ground-referenced sensors in dual-supply systems without level-shifting. |
| Phase-Reversal Protection | Yes - Prevents catastrophic output latch-up when IN− or IN+ dips below VCC−, critical for fault-tolerant sensor monitoring. |
Pinout & Package
16-pin SOIC (DW) package with exposed thermal pad; 1.27 mm pitch; 10.3 mm × 7.5 mm footprint; RθJA = 57°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | Drives 10 kΩ load to ±13.7 V swing; requires local 100 nF bypass capacitor for stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4188IDR | Lower VIO (25 μV max), zero-drift architecture, but only rated to 105°C and not radiation-hardened. | Preferred for commercial test equipment where ultra-low drift outweighs temperature/radiation requirements. | Select when sub-μV offset and near-zero drift dominate; avoid for space, avionics, or extended-temperature military use. |
| LMC6084IMX/NOPB | CMOS input (0.01 pA IIB), rail-to-rail output, but 1.3 MHz GBW and no phase-reversal protection. | Suitable for high-impedance pH or photodiode sensors in lab instruments-not for harsh-environment feedback control. | Choose for ultra-low input bias current needs; reject if phase-reversal immunity or −40°C to 125°C operation is mandatory. |
Compared with OPA4188IDR and LMC6084IMX/NOPB, the TLE2024QDWREP trades ultra-low offset and CMOS input impedance for guaranteed operation across −40°C to 125°C, integrated phase-reversal protection, and qualification for high-reliability aerospace platforms-making it irreplaceable in mission-critical analog signal chains where environmental robustness is non-negotiable.

FAQ
What is the maximum operating temperature range certified for the TLE2024QDWREP?
The TLE2024QDWREP is fully characterized and qualified for continuous operation from −40°C to 125°C, meeting JEDEC JESD22-A108 reliability standards including HAST, temperature cycling, and electromigration testing-essential for deployment in engine bays, satellite payloads, and desert-deployed military hardware.
Does the TLE2024QDWREP support single-supply operation?
Yes, the TLE2024QDWREP is explicitly specified for 5-V single-supply operation per the datasheet's recommended operating conditions. Its common-mode input range includes the negative rail (GND), and output swings to within 0.95 V of GND-enabling direct interface with microcontroller ADCs and low-voltage sensors without level-shifting circuitry.
How does phase-reversal protection function in the TLE2024QDWREP?
The TLE2024QDWREP integrates internal circuitry that prevents output polarity inversion when either input falls below the negative supply rail (VCC−). This eliminates the risk of erroneous control signals in sensor monitoring applications-such as thermocouple break detection-where input transients could otherwise trigger false alarms or unsafe actuation.
What is the typical supply current consumption of the TLE2024QDWREP at ±15 V?
At ±15 V supply and 25°C, the TLE2024QDWREP draws 1050 μA typical total supply current (262.5 μA per amplifier). The maximum is 1400 μA across −40°C to 125°C, enabling predictable power budgeting in thermally constrained avionics enclosures and battery-backed telemetry systems.
Is the TLE2024QDWREP pin-compatible with other TLE202x-EP variants?
Yes, all TLE202x-EP quad op-amps-including TLE2024QDWREP, TLE2024AQDWREP, and TLE2024MDWREP-share identical 16-pin SOIC (DW) pinouts and footprints. Differences lie solely in electrical specifications (e.g., VIO, tempco) and qualification grade (Q-suffix = −40°C to 125°C; M-suffix = −55°C to 125°C), allowing drop-in replacement within the same family.
