Product details
Overview
TLE2024AQDWREP from Texas Instruments is a quad-channel, high-speed, low-power precision operational amplifier engineered for automotive-grade operation (−40°C to 125°C), featuring 750 μV max input offset voltage at 25°C, 2 MHz unity-gain bandwidth, and 0.45 V/μs min slew rate under ±15 V supply. It delivers rail-to-rail-compatible common-mode input range including the negative rail and phase-reversal protection-enabling robust low-level signal conditioning in single- or split-supply sensor interfaces and data acquisition systems.
For engineers reviewing the TLE2024AQDWREP datasheet, TLE2024AQDWREP pinout, TLE2024AQDWREP application, or TLE2024AQDWREP equivalent, key selection criteria include its guaranteed automotive temperature rating, low 1.2 mA total quiescent current (300 μA per amplifier), 92–102 dB CMRR over temperature, and 16-pin SOIC (DW) package with validated 4-amplifier channel isolation and output drive capability up to ±40 mA.
Technical Context
The TLE2024AQDWREP uses Texas Instruments' Excalibur complementary bipolar process with isolated vertical PNP transistors, enabling higher unity-gain bandwidth and slew rate versus legacy precision op-amps like the OP21. Its bias circuit architecture ensures stable dc parameters across time and temperature-critical for long-life automotive and industrial instrumentation.
It integrates phase-reversal protection to prevent output state inversion when inputs dip below the negative supply rail, and supports dual supply (±2 V to ±20 V) or single 5-V operation. The device's common-mode input range extends to the negative rail, and its open-loop gain exceeds 0.4 V/μV (112 dB) at ±15 V, supporting high-accuracy closed-loop configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4188AIDWR | Zero-drift auto-zero architecture vs. Excalibur bipolar; 0.005 μV/°C offset drift vs. 2 μV/°C; 6.5 MHz GBW vs. 2 MHz | Better dc accuracy for ultra-stable integrators; higher power (1 mA/amp) and cost; not qualified for −40°C to 125°C automotive | Select for sub-μV offset-critical DC applications where supply current >1.2 mA is acceptable and temperature range ≤105°C suffices |
| LM2902QDRQ1 | Industry-standard BJT quad; 3 mV max VIO vs. 750 μV; 1.2 MHz GBW; no phase-reversal protection; 700 μA/amp supply current | Lower cost for non-precision functions; lacks rail-to-rail input and automotive temp guarantee; higher noise (40 nV/√Hz) | Select for cost-sensitive, non-automotive applications where 12-bit accuracy and −40°C operation are not required |
Compared with OPA4188AIDWR and LM2902QDRQ1, the TLE2024AQDWREP uniquely balances automotive temperature qualification, phase-reversal protection, and 750 μV offset within a 300 μA/amp power envelope-making it optimal for safety-critical sensor interfaces where reliability and moderate precision coexist.

FAQ
What is the maximum supply voltage rating for TLE2024AQDWREP?
The TLE2024AQDWREP supports absolute maximum supply voltages of +20 V on VCC+ and −20 V on VCC−, per the datasheet Absolute Maximum Ratings table. Operation beyond these limits risks permanent damage. Recommended operating range is ±2 V to ±20 V for dual supply or 4 V to 40 V for single supply, with full electrical specifications guaranteed from ±2 V to ±15 V.
Does TLE2024AQDWREP support single-supply operation?
Yes, TLE2024AQDWREP is fully specified for single 5-V operation, with common-mode input voltage range from 0 V to 3.2 V and output swing from 0.7 V to 4.2 V (RL = 10 kΩ). Its rail-to-negative-rail input capability allows direct interfacing with ground-referenced sensors without external level-shifting components.
What is the guaranteed input offset voltage specification for TLE2024AQDWREP over temperature?
TLE2024AQDWREP has a maximum input offset voltage of 1200 μV over the full −40°C to 125°C operating range, with 750 μV max at 25°C. Its temperature coefficient is tightly controlled at 2 μV/°C max, ensuring predictable drift behavior in automotive thermal cycling environments.
How does phase-reversal protection function in TLE2024AQDWREP?
TLE2024AQDWREP incorporates internal circuitry that prevents output polarity inversion when either input falls below the negative supply rail (e.g., during ESD events or sensor disconnection). This avoids erroneous system states in safety-critical applications such as engine knock detection or brake-by-wire sensor monitoring.
Is TLE2024AQDWREP pin-compatible with other TLE202x-EP quad op-amps?
Yes, all TLE202x-EP quad variants-including TLE2024AQDWREP, TLE2024QDWREP, and TLE2024MDWREP-share identical 16-pin SOIC (DW) pinouts and footprint. Differences are limited to offset voltage grade (A vs. standard), temperature range (Q vs. M suffix), and ordering packaging-enabling drop-in replacement within the same package variant.
