Product details
Overview
TLV274QPWRQ1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail output operational amplifier optimized for low-voltage, low-power sensor signal conditioning and precision analog front-ends. It delivers 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, and 550 µA per channel supply current across a 2.7-V to 16-V supply range, operating reliably from −40°C to 125°C in engine control units and battery management systems.
For engineers reviewing the TLV274QPWRQ1 datasheet, TLV274QPWRQ1 pinout, TLV274QPWRQ1 application, or TLV274QPWRQ1 equivalent, key selection criteria include its rail-to-rail output swing at 2.7-V operation, 1-pA input bias current enabling high-impedance sensor interfacing, and AEC-Q100 qualification for automotive powertrain and ADAS subsystems.
Technical Context
The TLV274QPWRQ1 employs CMOS input stage architecture with rail-to-rail output stage, supporting single-supply operation down to 2.7 V while maintaining 3-MHz bandwidth and 2.4 V/µs slew rate. Its input common-mode range extends from ground to VDD − 1.35 V, and output swings within 100 mV of each rail at 5-mA load.
Designed for automotive environments, it features 70–80 dB PSRR and 57–85 dB CMRR over frequency, with input offset voltage specified at 7 mV maximum across −40°C to 125°C. The device uses internal compensation for unity-gain stability with capacitive loads up to 10 pF; external series output resistance (RNULL ≥ 20 Ω) is recommended for larger loads.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274QDRQ1 | SOIC-14 package (D), 8.65 mm × 3.91 mm; 176°C/W θJA vs. 173.6°C/W for PW; same electrical specs. | Preferred for through-hole prototyping or legacy PCBs with SOIC footprints; less suitable for space-constrained ADAS modules. | Select TLV274QDRQ1 only when board layout mandates SOIC-14; otherwise TLV274QPWRQ1 offers superior thermal performance in TSSOP. |
| LMV324QDRQ1 | Lower bandwidth (1 MHz), higher supply current (160 µA/ch), rail-to-rail input/output, 1.8-V min supply. | Better suited for ultra-low-voltage (1.8–3.3 V) applications but lacks 3-MHz bandwidth needed for fast transient detection. | Choose LMV324QDRQ1 only if supply voltage is <2.7 V or power budget is tighter than 550 µA/ch; TLV274QPWRQ1 remains optimal for 3-MHz+ requirements. |
Compared with TLV274QDRQ1, TLV274QPWRQ1 provides identical analog performance in a smaller, thermally enhanced TSSOP-14 package ideal for modern automotive ECUs; versus LMV324QDRQ1, it delivers 3× higher bandwidth at only 3.4× higher quiescent current-critical for real-time sensor fusion in ADAS.

FAQ
What is the maximum capacitive load the TLV274QPWRQ1 can drive without instability?
The TLV274QPWRQ1 is unity-gain stable with capacitive loads up to 10 pF. For loads exceeding 10 pF, Texas Instruments recommends adding a series resistor (RNULL ≥ 20 Ω) between the output pin and the load capacitance to maintain phase margin above 65°. This configuration is validated in the datasheet Figure 25 and ensures reliable operation in ADC input buffering or cable-driving applications where stray capacitance exceeds 15 pF.
Does TLV274QPWRQ1 support true rail-to-rail input common-mode range?
No, TLV274QPWRQ1 features rail-to-rail *output* swing but not rail-to-rail input. Its input common-mode voltage range is specified from 0 V to VDD − 1.35 V at 25°C. At VDD = 3.3 V, this allows input signals from 0 V to 1.95 V-sufficient for most single-supply sensor interfaces but excluding direct ground-referenced signals at full temperature range. For true rail-to-rail input, consider TLV2374-Q1 instead.
What is the guaranteed input offset voltage specification for TLV274QPWRQ1 over temperature?
The TLV274QPWRQ1 guarantees a maximum input offset voltage of 7 mV across the full automotive temperature range of −40°C to 125°C. At 25°C, the typical value is 0.5 mV with a maximum of 5 mV. This specification is critical for precision current sensing and thermistor linearization where offset drift directly impacts measurement accuracy in engine control algorithms.
Can TLV274QPWRQ1 operate from a single 3.3-V supply in an automotive infotainment system?
Yes, TLV274QPWRQ1 operates reliably from a single 3.3-V supply, delivering full rail-to-rail output swing and 3-MHz bandwidth. Its 2.7-V minimum supply voltage and −40°C to 125°C rating make it suitable for infotainment head units located near dashboard displays, where ambient temperatures exceed 85°C. The 550-µA per channel supply current also aligns with low-power MCU co-location requirements.
How does TLV274QPWRQ1 compare to TLC274-Q1 in terms of power efficiency and bandwidth?
TLV274QPWRQ1 improves on TLC274-Q1 by reducing minimum supply voltage from 3 V to 2.7 V and increasing bandwidth from 1.7 MHz to 3 MHz-all while maintaining nearly identical 550-µA per channel supply current (TLC274-Q1 draws 675 µA/ch). This makes TLV274QPWRQ1 a direct functional upgrade for battery-powered automotive subsystems requiring faster transient response without increasing power budget.
