Product details
Overview
TLE2024AQDWRQ1 from Texas Instruments is a quad-channel, automotive-grade precision operational amplifier optimized for low-power, high-speed signal conditioning in harsh environments. It delivers 2.8 MHz unity-gain bandwidth, 0.7 V/µs slew rate (±15V), 1000 µV max input offset voltage (–40°C to +125°C), and operates across ±2V to ±20V dual or 4V to 40V single supply. It is used in battery management systems for current-sense amplification under wide temperature variation.
For engineers reviewing the TLE2024AQDWRQ1 datasheet, TLE2024AQDWRQ1 pinout, TLE2024AQDWRQ1 application, or TLE2024AQDWRQ1 equivalent, key selection criteria include its AEC-Q100 qualification (–40°C to +125°C), phase-reversal protection, rail-to-rail input capability (to negative rail), and low 1.2 mA typical total supply current at 5V single supply - critical for automotive body electronics and OBC sensor interfaces.
Technical Context
The TLE2024AQDWRQ1 employs a proprietary Texas Instruments bipolar process with integrated bias circuitry, delivering exceptional parameter stability over time and temperature. Its architecture supports both single-supply (5V) and split-supply (±15V) operation while maintaining precision dc performance - including 92 dB min CMRR and 98 dB min PSRR - even at automotive extremes.
Phase-reversal protection prevents output inversion when inputs fall below the negative rail, enabling robust interfacing with sensors operating near ground in 5V automotive systems. The device's common-mode input range extends to the negative rail, making it suitable for low-side current sensing without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact integration of four independent precision gain stages in one SOIC-16 package. |
| Supply Voltage Range | ±2V to ±20V dual or 4V to 40V single - supports legacy 12V/24V automotive rails and modern 5V microcontroller domains. |
| Input Offset Voltage (max) | 1200 µV over –40°C to +125°C - ensures <1.2 mV error in 100 mV full-scale current-sense applications at worst-case temp. |
| Unity-Gain Bandwidth | 2.8 MHz (±15V), 1.7 MHz (5V) - sufficient for closed-loop control loops up to ~200 kHz with adequate phase margin. |
| Slew Rate (min) | 0.7 V/µs (±15V), 0.5 V/µs (5V) - supports fast transient response in motor phase-current feedback paths. |
| Input Bias Current (max) | 90 nA over temperature - minimizes voltage error across high-impedance sensor bridges or thermistor networks. |
| ESD Protection | Exceeds 1000 V per MIL-STD-883 Method 3015 - meets automotive board-level ESD robustness requirements. |
Pinout & Package
Package: DW (SOIC-16), 10.3 mm × 7.5 mm body, 1.27 mm pitch, surface-mount. Thermal resistance RθJA = 62.7°C/W enables reliable operation at 1.4 mA supply current in ambient up to +125°C with minimal heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 10, 16 | OUT A/B/C/D | Amplifier outputs - each drives ≥10 kΩ load with rail-swing capability (e.g., 3.7 V to 0.95 V on 5V supply). |
| 2, 6, 11, 15 | –IN A/B/C/D | Inverting inputs - accept differential signals down to VCC–; enable precision inverting configurations. |
| 3, 5, 12, 14 | +IN A/B/C/D | Noninverting inputs - support rail-to-rail common-mode range (to negative rail), ideal for low-side sensing. |
| 4 | VCC+ | Positive power supply terminal - connects to main system rail (e.g., 5V or +15V). |
| 13 | VCC– | Negative power supply terminal - ties to ground (single-supply) or –15V (dual-supply); reference for all inputs/outputs. |
| 8, 9 | NC | No internal connection - must be left floating; no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from –40°C to +125°C ambient, meeting automotive reliability and lifetime requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902QDRQ1 | Lower bandwidth (1.2 MHz), higher offset (7000 µV max), no phase-reversal protection. | Acceptable for non-critical DC sensing but unsuitable for fast transient or low-side shunt monitoring. | Select when cost is primary constraint and phase-reversal risk is mitigated by external design. |
| OPA4197IPWPR | Higher precision (10 µV offset), rail-to-rail I/O, lower noise (5.5 nV/√Hz), but not AEC-Q100 qualified. | Preferred for high-end ADAS sensor front-ends where qualification is handled at system level. | Choose for superior ac/dc performance where automotive qualification is managed externally or waived. |
Compared with LM2902QDRQ1, TLE2024AQDWRQ1 provides 2.3× higher bandwidth and guaranteed phase-reversal immunity - essential for unattended low-side current sensing. Against OPA4197IPWPR, it trades 10× lower offset for AEC-Q100 compliance and proven field reliability in under-hood environments.

FAQ
What is the maximum operating temperature range for the TLE2024AQDWRQ1?
The TLE2024AQDWRQ1 is qualified per AEC-Q100 Grade 1 and operates continuously from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, ensuring functional reliability in under-hood automotive environments.
Does the TLE2024AQDWRQ1 support single-supply operation?
Yes, the TLE2024AQDWRQ1 supports single-supply operation from 4V to 40V. At 5V supply, it delivers 1.7 MHz gain bandwidth, 0.5 V/µs slew rate, and common-mode input range extending to ground (0 V), enabling direct interface with low-side current shunts and 3.3V/5V microcontrollers without level shifters.
What is the purpose of the NC pins (8 and 9) on the TLE2024AQDWRQ1?
Pins 8 and 9 on the TLE2024AQDWRQ1 are No Connect (NC) terminals with no internal connection. They must be left electrically floating - neither tied to ground nor powered. Routing traces or applying solder to these pins has no functional effect and may compromise mechanical integrity or thermal performance of the SOIC-16 package.
How does phase-reversal protection work in the TLE2024AQDWRQ1?
The TLE2024AQDWRQ1 integrates internal circuitry that prevents output polarity inversion when either input falls below the negative supply rail (VCC–). This eliminates the need for external diode clamps in low-side shunt monitor designs, reducing component count and improving reliability in automotive current-sensing applications.
Is the TLE2024AQDWRQ1 pin-compatible with other devices in the TLE202x-Q1 family?
No - the TLE2024AQDWRQ1 uses a 16-pin SOIC (DW) package, while the TLE2021-Q1 and TLE2022-Q1 use 8-pin SOIC (D) packages. Pin functions differ across channel counts; direct PCB replacement is not possible without layout revision. Functional equivalence exists only at the schematic level for quad vs. dual/single implementations.
