Product details
Overview
TLE2024QDWRQ1 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 2.8MHz gain bandwidth, 0.7V/µs slew rate (±15V), 1000µV max input offset voltage, 50nA max input bias current, and operates across –40°C to +125°C. It is used in battery management systems for cell voltage monitoring with rail-to-rail-compatible input stage.
For engineers reviewing the TLE2024QDWRQ1 datasheet, TLE2024QDWRQ1 pinout, TLE2024QDWRQ1 application, or TLE2024QDWRQ1 equivalent, key selection criteria include AEC-Q100 qualification, quad-channel integration in SOIC-16, single- or dual-supply operation (5V or ±15V), phase-reversal protection, and stable dc performance over temperature.
Technical Context
The TLE2024QDWRQ1 employs a proprietary Texas Instruments bipolar process with integrated bias circuitry, enabling exceptional parameter stability over time and temperature. Its input stage includes phase-reversal protection, allowing safe operation when inputs fall below the negative rail - critical for automotive sensor interfaces with unpredictable common-mode transients.
It supports both single-supply (5V) and split-supply (±15V) configurations, with common-mode input range extending to the negative rail and output swing within 0.95V of rails (5V supply). The device achieves 92–102dB CMRR and 98–112dB PSRR under ±15V conditions, ensuring robust noise immunity in electric powertrain and body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-sensor signal conditioning without board-level duplication. |
| Supply Current | 1.2mA max (±15V) - supports low-quiescent-power BMS and lighting control subsystems. |
| Unity-Gain Bandwidth | 2.8MHz (±15V) - sufficient for fast-response motor current sensing and OBC feedback loops. |
| Slew Rate | 0.7V/µs (±15V) - preserves fidelity of transient-rich signals in inverter gate driver monitoring. |
| Input Offset Voltage | ±1200µV max (–40°C to +125°C) - ensures <1% error in 12-bit ADC front-end applications at full temp range. |
| Common-Mode Range | Extends to V– - allows direct interface with shunt-based current sensors referenced to ground or negative rail. |
| ESD Protection | 1000V HBM - meets automotive system-level ESD robustness requirements per ISO 10605. |
Pinout & Package
DW package: 16-pin SOIC, 7.5mm × 10.3mm body, 1.27mm pitch, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 10, 16 | OUT A/B/C/D | Amplified outputs - each independently drives 10kΩ load with >13.7V swing (±15V) or >3.7V (5V). |

| 4 | V+ | Positive supply - connects to +15V or +5V; decoupling capacitor required per channel group. |
| 13 | V– | Negative supply - connects to 0V (single) or –15V (dual); serves as reference for all inputs/outputs. |
| 8, 9 | NC | No internal connection - must be left floating; no routing or grounding permitted. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 | Qualified for –40°C to +125°C ambient operation - eliminates derating calculations for under-hood and powertrain ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9064QDRQ1 | Rail-to-rail I/O, lower 50µV offset, but only 10V/µs slew rate and 10MHz GBW; CMOS process, higher input capacitance. | Better for low-voltage (1.8–5.5V) sensor nodes; unsuitable for ±15V analog front-ends or fast transient capture. | Select TLV9064QDRQ1 only if supply is strictly ≤5.5V and offset-critical DC accuracy outweighs speed needs. |
| OPA4197QDGKRQ1 | Lower 25µV offset, 10V/µs slew rate, 10MHz GBW, higher 1.5mA supply current; includes EMI hardening. | Preferred for high-precision position sensing or resolver interfaces where EMI immunity is critical. | Choose OPA4197QDGKRQ1 when EMI robustness or sub-50µV offset is mandatory, accepting higher power and cost. |
Compared with TLV9064QDRQ1 and OPA4197QDGKRQ1, the TLE2024QDWRQ1 provides optimal balance of speed (2.8MHz), low power (1.2mA), and ±15V compatibility - making it uniquely suited for legacy automotive analog subsystems requiring bipolar supply operation without sacrificing AEC-Q100 compliance.

FAQ
What is the maximum operating temperature range for the TLE2024QDWRQ1?
The TLE2024QDWRQ1 is qualified per AEC-Q100 Grade 1 and operates from –40°C to +125°C ambient temperature. This rating applies to the full device specification including input offset voltage, supply current, and gain bandwidth - no derating is required within this range. All electrical characteristics in the datasheet are guaranteed across this interval, making the TLE2024QDWRQ1 suitable for under-hood and powertrain control unit deployments where thermal stress is extreme.
Does the TLE2024QDWRQ1 support single-supply operation?
Yes, the TLE2024QDWRQ1 supports true single-supply operation at 5V. Its common-mode input voltage range extends to the negative rail (0V), and output swings to within 0.95V of the positive rail and 0.7V of ground under 10kΩ load. This enables direct interfacing with ground-referenced sensors like NTC thermistors or shunt resistors without level-shifting circuitry - a key advantage in space-constrained automotive modules such as door control units or seat electronics.
What is the purpose of the phase-reversal protection in the TLE2024QDWRQ1?
The phase-reversal protection in the TLE2024QDWRQ1 prevents output polarity inversion when either input falls below the negative supply rail - a condition that can occur during sensor open-circuit faults or transient events in automotive systems. Unlike standard op-amps that may latch or produce erroneous outputs, the TLE2024QDWRQ1 maintains predictable behavior, ensuring functional safety in critical applications like brake-by-wire voltage monitors or airbag crash sensor signal chains.
How many operational amplifiers are integrated into the TLE2024QDWRQ1?
The TLE2024QDWRQ1 integrates four independent, matched operational amplifiers in a single 16-pin SOIC (DW) package. Each channel has dedicated inverting and noninverting inputs and an output pin, with shared V+ and V– supply connections. This quad configuration reduces component count and PCB area in multi-channel sensing applications such as three-phase motor current monitoring plus temperature compensation in EV inverters.
Is the TLE2024QDWRQ1 pin-compatible with other devices in the TLE202x-Q1 family?
No, the TLE2024QDWRQ1 is not pin-compatible with the single-channel TLE2021-Q1 or dual-channel TLE2022-Q1, as it uses a 16-pin DW SOIC package versus their 8-pin D SOIC packages. However, its pinout follows TI's standard quad-op-amp layout (e.g., matching OPA4197QDGKRQ1 in channel assignment order), enabling consistent PCB layout practices across TI's automotive op-amp portfolio when migrating between performance tiers.
