Product details
Overview
TLE2024QDWRG4Q1 from Texas Instruments is a quad-channel, automotive-grade precision operational amplifier designed for low-power, high-speed signal conditioning in harsh environments. It delivers 2.8MHz gain bandwidth, 0.7V/µs slew rate (±15V), 1000µV max input offset voltage, and operates across –40°C to +125°C. It supports single-supply (5V) and dual-supply (±15V) configurations with rail-to-rail common-mode input including the negative rail - ideal for battery management and motor control feedback loops.
For engineers reviewing the TLE2024QDWRG4Q1 datasheet, TLE2024QDWRG4Q1 pinout, TLE2024QDWRG4Q1 application, or TLE2024QDWRG4Q1 equivalent, key selection criteria include its AEC-Q100 qualification, low 1.2mA total supply current at 5V, phase-reversal protection, and SOIC-16 DW package compatibility with high-density automotive PCB layouts.
Technical Context
The TLE2024QDWRG4Q1 uses a proprietary Texas Instruments bipolar process optimized for stable dc performance over temperature and time. Its bias circuitry ensures minimal supply-current drift and maintains precision specifications - including input offset voltage drift of ±2µV/°C - across the full automotive temperature range.
It integrates phase-reversal protection to prevent output polarity inversion when inputs fall below the negative supply rail, and supports both single-supply (VICR down to 0V at 5V) and split-supply operation (VICR from –15V to +13.2V at ±15V), enabling flexible use in sensor front-ends and power stage monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact integration of four independent signal paths in one SOIC-16 package. |
| Supply Current (max) | 1.4mA at ±15V - enables low-power operation in always-on automotive subsystems. |
| Unity-Gain Bandwidth | 2.8MHz at ±15V - supports accurate amplification of medium-frequency sensor signals up to ~1MHz. |
| Slew Rate (min) | 0.7V/µs at ±15V - ensures faithful reproduction of fast transients in motor current sensing. |
| Input Offset Voltage (max) | 1200µV over –40°C to +125°C - defines worst-case dc error in precision voltage monitoring applications. |
| Common-Mode Input Range | Includes negative rail (0V at 5V supply) - allows direct interface with ground-referenced sensors without level-shifting. |
| ESD Protection | >1000V per MIL-STD-883 Method 3015 - enhances robustness in assembly and vehicle-level ESD events. |
Pinout & Package
Package: DW (SOIC-16), 10.3mm × 7.5mm body, 1.27mm pitch, surface-mount. Thermal resistance RθJA = 62.7°C/W enables reliable operation at full automotive temperature range with standard PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 10, 16 | OUT A/B/C/D | Amplified output terminals for each of four independent op-amp channels. |
| 2, 6, 11, 15 | –IN A/B/C/D | Inverting inputs - connect to feedback networks or differential sensing nodes. |
| 3, 5, 12, 14 | +IN A/B/C/D | Noninverting inputs - accept sensor signals, reference voltages, or setpoints. |
| 4 | VCC+ | Positive supply rail - must be decoupled locally for stability in noise-sensitive analog sections. |
| 13 | VCC– | Negative supply rail - serves as analog ground reference in single-supply mode or true negative rail in dual-supply mode. |
| 8, 9 | NC | No internal connection - must be left floating; not tied to ground or supply. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C operation - meets automotive electronics reliability requirements without derating. |
| Phase-reversal protection | Prevents output latch-up or polarity flip when input goes below VCC– - critical for fault-tolerant BMS and inverter gate driver monitoring. |
| Rail-inclusive common-mode range | Accepts inputs at or below VCC– - eliminates need for external level-shifting in shunt-based current sensing. |
| Low 19nV/√Hz input voltage noise | Minimizes added noise in µV-level thermocouple or strain gauge signal chains at 10Hz. |
| Stable parameters over time/temperature | Drift-limited design ensures long-term calibration integrity in infotainment audio preamps and ADAS sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902QDRQ1 | Lower bandwidth (1.2MHz), higher input offset (3mV max), no phase-reversal protection | Cost-optimized general-purpose use; unsuitable for fast transient or rail-to-rail input-critical designs | Select when budget constraints outweigh precision and protection needs in non-safety-critical body electronics |
| OPA4197QDGQRQ1 | Higher precision (10µV offset), rail-to-rail I/O, lower noise (5.5nV/√Hz), but higher supply current (1mA/channel) | Better for ultra-low-noise, high-accuracy applications like ADAS radar signal conditioning | Choose when sub-100µV offset and RRO are mandatory, and power budget permits 4× higher quiescent current |
Compared with LM2902QDRQ1, TLE2024QDWRG4Q1 provides superior transient response and fault resilience; versus OPA4197QDGQRQ1, it trades some precision and noise performance for significantly lower power and proven robustness in legacy automotive analog signal chains.

FAQ
What is the maximum operating temperature range for the TLE2024QDWRG4Q1?
The TLE2024QDWRG4Q1 is qualified per AEC-Q100 Grade 1 and operates reliably from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and open-loop gain, making it suitable for engine bay and powertrain control module deployments where thermal margins are critical.
Does the TLE2024QDWRG4Q1 support single-supply operation?
Yes, the TLE2024QDWRG4Q1 supports true single-supply operation at 5V. Its common-mode input voltage range extends to the negative rail (0V), and output swing reaches within 0.95V of the negative rail at 5V supply - enabling direct interface with ground-referenced sensors and microcontroller ADCs without external level-shifting circuitry.
What is the purpose of the NC pins (8 and 9) on the TLE2024QDWRG4Q1?
Pins 8 and 9 on the TLE2024QDWRG4Q1 are designated No Connection (NC) and have no internal bond wire or silicon connection. They must be left unconnected and floating - neither tied to ground nor supply - to avoid unintended parasitic coupling or mechanical stress on the die attach. This is explicitly confirmed in Table 4-3 of the TI datasheet SGLS199C.
How does phase-reversal protection function in the TLE2024QDWRG4Q1?
Phase-reversal protection in the TLE2024QDWRG4Q1 prevents output polarity inversion when either input falls below the negative supply rail (VCC–). Internally, this is implemented via input-stage clamping and bias control that maintains correct amplifier behavior - crucial for safety-critical current sensing in BMS and inverter control where erroneous output states could trigger false fault shutdowns.
Is the TLE2024QDWRG4Q1 pin-compatible with other devices in the TLE202x-Q1 family?
No - the TLE2024QDWRG4Q1 (quad, SOIC-16 DW) is not pin-compatible with the TLE2021-Q1 (single, SOIC-8 D) or TLE2022-Q1 (dual, SOIC-8 D). Pin count, layout, and terminal assignments differ fundamentally. However, all share identical electrical architecture and specification methodology, enabling consistent design reuse across channel-count variants when board redesign is acceptable.
