Product details
Overview
TLV2374QPWRG4Q1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail input/output operational amplifier designed for precision signal conditioning in engine control units, battery management systems, and HEV/EV inverters. It delivers 3 MHz unity-gain bandwidth, 2.4 V/µs slew rate, 550 µA per channel supply current, and operates across 2.7 V to 16 V with –40°C to 125°C ambient temperature range.
For engineers reviewing the TLV2374QPWRG4Q1 datasheet, TLV2374QPWRG4Q1 pinout, TLV2374QPWRG4Q1 application, or TLV2374QPWRG4Q1 equivalent, key selection considerations include rail-to-rail I/O swing at low supply voltage, ultra-low input bias current (1 pA), high CMRR (up to 84 dB), input offset voltage drift (2 µV/°C), and AEC-Q100 Grade 1 qualification for automotive safety-critical subsystems.
Technical Context
The TLV2374QPWRG4Q1 employs CMOS input stage architecture enabling high-impedance sensing and low quiescent current, supporting start-stop functionality and direct 12-V battery interfacing. Its rail-to-rail output stage maximizes dynamic range without clipping, while wide common-mode input range (0 V to VDD) eliminates phase reversal concerns across full supply rails.
It features no shutdown function, fixed gain configuration, and supports single-supply operation only - not split-supply. Thermal design is enabled by RθJA = 121 °C/W (TSSOP-14) and junction-to-board thermal resistance of 62.8 °C/W, making it suitable for thermally constrained automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports both low-voltage microcontroller interfaces and direct 12-V automotive battery connection. |
| Bandwidth (UGBW) | 3 MHz - enables accurate amplification of fast sensor signals such as crankshaft position or current-sense transients. |
| Slew Rate | 2.4 V/µs - ensures faithful reproduction of high-slew input steps without distortion in motor control feedback loops. |
| Input Bias Current | 1 pA - minimizes voltage error in high-impedance sensor interfaces like thermistors or piezoelectric elements. |
| Input Offset Voltage | 4.5 mV max (25°C) - defines baseline DC accuracy for precision analog front-ends in BMS voltage monitoring. |
| CMRR | 84 dB max (VDD = 15 V) - rejects common-mode noise from noisy power domains in ECU and inverter gate drivers. |
| Quiescent Current | 550 µA per channel - enables multi-channel signal conditioning in always-on automotive subsystems without excessive battery drain. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2374QDRQ1 | Same electrical specs; SOIC-14 package (8.65 mm × 3.91 mm), higher RθJA (67 °C/W) vs TSSOP's 121 °C/W. | Better thermal performance in high-power-density layouts; less suitable for ultra-thin modules due to larger footprint. | Select TLV2374QDRQ1 when board space permits and thermal dissipation >150 mW is required. |
| TLC2274QDRQ1 | Lower bandwidth (2.2 MHz), higher supply current (1100 µA/ch), rail-to-rail output only (not input), 300 µV VIO typical. | Higher precision offset but reduced speed and efficiency - better for static sensor calibration than dynamic motor control. | Choose TLC2274QDRQ1 where ultra-low offset dominates over bandwidth and power constraints. |
Compared with TLV2374QDRQ1, TLV2374QPWRG4Q1 offers superior board-area efficiency and thermal resistance matching for compact automotive modules; versus TLC2274QDRQ1, it trades 100 µV lower VIO for 0.8 MHz higher bandwidth and 550 µA lower per-channel current - favoring real-time control over static measurement.

FAQ
What is the operating temperature range for TLV2374QPWRG4Q1?
The TLV2374QPWRG4Q1 is qualified for automotive Grade 1 operation, with a specified ambient operating temperature range of –40°C to 125°C. This rating is validated per AEC-Q100 standards and applies across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current - ensuring reliable performance in under-hood and powertrain environments.
Does TLV2374QPWRG4Q1 support dual-supply operation?
No, TLV2374QPWRG4Q1 is designed exclusively for single-supply operation from 2.7 V to 16 V. Its input common-mode range extends from 0 V to VDD, and its rail-to-rail output swings from GND to VDD - eliminating the need for negative rails. Split-supply use is neither specified nor recommended, as absolute maximum ratings do not cover negative VDD conditions.
What is the maximum capacitive load TLV2374QPWRG4Q1 can drive stably?
TLV2374QPWRG4Q1 maintains stable operation with capacitive loads up to 100 pF when configured as a unity-gain buffer (AV = 1), as confirmed by phase margin measurements ≥65° in Figure 19 of the datasheet. For loads exceeding 100 pF, external series resistance (≥100 Ω) at the output is recommended to preserve stability in high-precision sensor interfaces.
Is TLV2374QPWRG4Q1 pin-compatible with standard TLV2374 variants?
Yes, TLV2374QPWRG4Q1 shares identical pinout and electrical behavior with non-automotive TLV2374 variants in TSSOP-14 packaging. However, it differs in qualification - only TLV2374QPWRG4Q1 carries AEC-Q100 Grade 1 certification, enhanced ESD robustness (HBM ±2 kV), and automotive-specific reliability testing. Functional compatibility is maintained, but automotive use requires the Q1 suffix part.
What PCB layout practices improve thermal performance of TLV2374QPWRG4Q1?
To optimize thermal performance of TLV2374QPWRG4Q1 in TSSOP-14, use a minimum 25 mm² copper pour connected to Pin 11 (GND) on the top layer, thermally stitched to inner ground planes via ≥4 vias (0.3 mm diameter). Avoid placing heat-generating components within 3 mm. The device's ψJB = 62.2 °C/W means board-level conduction dominates cooling - so thermal relief on GND pads must be minimized.
