Product details
Overview
TLV2374QPWRQ1 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 gain-bandwidth, 2.4 V/µs slew rate, 550 µA/channel supply current, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V across –40°C to 125°C.
For engineers reviewing the TLV2374QPWRQ1 datasheet, TLV2374QPWRQ1 pinout, TLV2374QPWRQ1 application, or TLV2374QPWRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, rail-to-rail I/O swing at low supply voltage, ultra-low input bias current (1 pA), high CMRR (>66 dB), and SOIC-14/TSSOP-14 packaging for automotive PCB layouts.
Technical Context
The TLV2374QPWRQ1 uses CMOS input stage architecture enabling 1 pA input bias current and rail-to-rail common-mode input range (0 V to VDD). Its unity-gain-stable design supports closed-loop configurations up to 3 MHz with phase margin ≥65° into 100 pF capacitive load.
It features high open-loop gain (106 dB at 2.7 V), wide supply rejection (80 dB PSRR), and robust output drive capability: VOH ≥ 14.9 V and VOL ≤ 0.08 V at 1 mA load with 15 V supply - enabling direct interfacing with 12-V automotive sensors and microcontrollers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports start-stop battery transients and direct 12-V system connection |
| Gain-Bandwidth Product | 3 MHz - enables stable amplification of kHz-range sensor signals (e.g., current sense, throttle position) |
| Slew Rate | 2.4 V/µs - preserves fidelity of fast transient signals like ignition pulses or PWM feedback |
| Input Offset Voltage | 4.5 mV max (25°C) - ensures <±1% error in 12-bit ADC front-end applications |
| Input Bias Current | 1 pA typ - eliminates significant offset drift in high-impedance sensor interfaces (e.g., thermistors, piezoelectric) |
| Common-Mode Rejection | 66 dB min (–40°C to 125°C) - maintains accuracy in noisy automotive ground environments |
| Output Drive | ±100 mA short-circuit current - sustains operation under fault conditions without latch-up |
Pinout & Package
TLV2374QPWRQ1 is available in 14-pin SOIC (D) and TSSOP (PW) packages. Both measure 8.65 mm × 3.91 mm (SOIC) or 5.00 mm × 4.40 mm (TSSOP), with 1.27 mm pitch and standard JEDEC footprint compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (Ch1–Ch4) | Amplified buffered output per channel; rail-to-rail swing supports full dynamic range utilization |
| 2, 6, 9, 13 | Inverting Input (Ch1–Ch4) | Differential input node; accepts signals down to GND and up to VDD without phase reversal |
| 3, 5, 10, 12 | Noninverting Input (Ch1–Ch4) | High-impedance (1 TΩ) node; enables precision voltage monitoring with minimal loading |
| 4 | VDD | Positive supply rail; decoupling capacitor required within 1 cm for stability at 3 MHz |
| 11 | GND | Negative supply reference; must be connected to low-impedance chassis or power plane |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 | Qualified for –40°C to 125°C ambient operation - meets automotive powertrain and body electronics requirements |
| Rail-to-Rail I/O | Input common-mode range extends to both supply rails; output swings within 100 mV of VDD/GND - maximizes ADC resolution |
| Ultra-Low Power | 550 µA/channel quiescent current - enables always-on sensing in battery-critical modules (e.g., BMS sleep mode) |
| High ESD Robustness | ±2000 V HBM / ±500 V CDM - withstands assembly handling and in-vehicle electrostatic events |
| No Phase Reversal | Operates correctly even when input exceeds supply rails - prevents latch-up in overvoltage sensor faults |
Applications

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 (D) vs TSSOP-14 (PW) - 8.65 mm × 3.91 mm vs 5.00 mm × 4.40 mm body | SOIC offers higher thermal resistance (RθJA = 67°C/W vs 121°C/W) - preferred for lower-power or forced-air-cooled designs | Select TLV2374QDRQ1 for legacy SOIC footprints; TLV2374QPWRQ1 for space-constrained boards requiring TSSOP density |
| TLC2274QDRQ1 | Lower bandwidth (2.2 MHz), higher supply current (1100 µA/ch), rail-to-rail output only (not input) | Not suitable for rail-to-rail input sensing at low VDD (e.g., 2.7 V start-stop); higher power limits always-on use | Choose TLC2274QDRQ1 only if higher output drive (±50 mA) is prioritized over input range and quiescent current |

FAQ
What is the operating temperature range for TLV2374QPWRQ1?
TLV2374QPWRQ1 is qualified for ambient operating temperatures from –40°C to +125°C per AEC-Q100 Grade 1 requirements. This range covers under-hood and cabin-mounted automotive applications, including engine control units and battery management systems where thermal extremes are routine.
Does TLV2374QPWRQ1 support rail-to-rail input and output simultaneously?
Yes, TLV2374QPWRQ1 supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of VDD and GND at 1 mA load). This dual capability eliminates clipping in single-supply systems and maximizes dynamic range for ADC interfacing.
What is the maximum supply voltage rating for TLV2374QPWRQ1?
The absolute maximum supply voltage for TLV2374QPWRQ1 is 16.5 V, with recommended operation up to 16 V. This allows direct connection to 12-V automotive batteries, including cranking transients up to 16 V, without external regulators or protection circuitry.
Is TLV2374QPWRQ1 pin-compatible with other TLV237x-Q1 variants?
No - TLV2374QPWRQ1 (14-pin TSSOP) is not pin-compatible with TLV2371-Q1 (5-pin SOT-23) or TLV2372-Q1 (8-pin SOIC). However, its 14-pin pinout matches TLV2374QDRQ1 (SOIC-14) exactly, enabling drop-in replacement between D and PW packages with layout adaptation.
What packaging options are available for TLV2374QPWRQ1?
TLV2374QPWRQ1 is offered exclusively in the 14-pin TSSOP (PW) package measuring 5.00 mm × 4.40 mm. The functionally identical TLV2374QDRQ1 uses the 14-pin SOIC (D) package (8.65 mm × 3.91 mm) - both share identical electrical specifications and AEC-Q100 qualification.
