Product details
Overview
TLV274QPWRG4Q1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail output operational amplifier optimized for low-power, wide-supply applications. 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, with input bias current as low as 1 pA and input noise voltage of 39 nV/√Hz at 1 kHz - enabling precision sensor interfacing in battery-powered ADAS modules.
For engineers reviewing the TLV274QPWRG4Q1 datasheet, TLV274QPWRG4Q1 pinout, TLV274QPWRG4Q1 application, or TLV274QPWRG4Q1 equivalent, key selection criteria include its AEC-Q100 qualification, −40°C to 125°C operating range, rail-to-rail output swing down to 0.1 V from rails at 5 mA load, and compatibility with Li-ion and MSP430-based systems requiring micropower analog signal conditioning.
Technical Context
The TLV274QPWRG4Q1 uses CMOS input stage architecture to achieve ultra-low input bias current (1 pA typical) and high input impedance, making it suitable for high-impedance transducer interfaces such as piezoelectric sensors and pH electrodes. Its rail-to-rail output stage supports full dynamic range utilization in single-supply configurations without level-shifting circuitry.
It operates stably with capacitive loads up to 10 pF; for larger loads, a series null resistor (RNULL ≥ 20 Ω) is recommended at the output to maintain ≥65° phase margin. The device is fully specified for both single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) operation, with PSRR of 70 dB and CMRR of 80 dB at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct integration with Li-ion batteries (3.0–4.2 V), 5-V microcontrollers, and 12-V automotive systems without regulation. |
| Bandwidth | 3 MHz - enables accurate amplification of medium-frequency signals like ultrasonic sensor echoes or motor current feedback up to ~300 kHz. |
| Slew Rate | 2.4 V/µs - ensures <2 µs settling time for 1-V step inputs, critical for fast transient response in closed-loop motor control. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor circuits (e.g., >1 GΩ source impedance), preserving accuracy in medical ECG front-ends. |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - provides low-noise signal conditioning for precision thermistor or strain gauge measurements in automotive cabin climate control. |
| Operating Temperature | −40°C to 125°C - qualified per AEC-Q100 Grade 1, enabling use in engine bay, transmission, and brake-by-wire ECUs. |
| Rail-to-Rail Output | Swings within 0.15 V of rails at 1 mA load - maximizes dynamic range in 3.3-V or 5-V ADC-driven systems without external level shifters. |
Pinout & Package
TSSOP-14 package (PW), 5.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant matte tin lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A; capable of sourcing/sinking ±100 mA, rail-to-rail swing under load. |
| 2 | IN− A | Inverting input of Channel A; high-impedance CMOS node (1 pA bias), sensitive to PCB leakage and guarding requirements. |
| 3 | IN+ A | Non-inverting input of Channel A; matched to IN− A for optimal common-mode rejection. |
| 4 | VDD | Positive power supply for all four channels; requires local 0.1-µF ceramic + 6.8-µF tantalum decoupling. |
| 5 | IN+ B | Non-inverting input of Channel B; electrically isolated from Channel A but shares VDD/GND. |
| 6 | IN− B | Inverting input of Channel B; identical electrical characteristics to IN− A. |
| 7 | OUT B | Amplified output of Channel B; independent output stage, no crosstalk with Channel A beyond shared supply. |
| 8 | GND | Analog ground reference for all channels; must connect to low-impedance ground plane with minimal trace inductance. |
| 9 | OUT C | Amplified output of Channel C; supports simultaneous multi-sensor signal conditioning (e.g., 3-axis IMU analog outputs). |
| 10 | IN− C | Inverting input of Channel C; layout symmetry with other inputs improves matching and reduces thermal EMF errors. |
| 11 | IN+ C | Non-inverting input of Channel C; same input offset voltage drift (2 µV/°C) as other channels. |
| 12 | VDD | Redundant VDD connection - must be tied to same net as Pin 4 for thermal and EMI performance. |
| 13 | IN+ D | Non-inverting input of Channel D; enables fourth independent gain stage in compact footprint. |
| 14 | IN− D | Inverting input of Channel D; matches IN− A/B/C for consistent AC/DC performance across all channels. |

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 (larger footprint, higher θJA = 122.3°C/W), same electrical specs and AEC-Q100 qualification. | Preferred where board space permits and legacy SOIC assembly lines are used; less suitable for dense ADAS camera modules. | Select TLV274QDRQ1 when TSSOP reflow capability is unavailable or mechanical mounting requires through-hole-compatible footprint. |
| LMV324QDRQ1 | Lower bandwidth (1 MHz), higher supply current (160 µA/ch), no rail-to-rail output (1.5-V headroom), but lower input offset (3 mV max). | Better suited for cost-sensitive body control modules where speed and rail-to-rail swing are not required. | Choose LMV324QDRQ1 only for non-critical 5-V systems with relaxed accuracy and bandwidth needs - not for precision sensor front-ends. |
Compared with TLV274QDRQ1, TLV274QPWRG4Q1 offers 35% smaller PCB area and improved thermal performance (θJA = 173.6°C/W vs. 122.3°C/W); versus LMV324QDRQ1, it delivers 3× bandwidth, rail-to-rail output, and 3.5× lower input bias current - essential for high-impedance automotive sensors.

FAQ
What is the maximum capacitive load the TLV274QPWRG4Q1 can drive without instability?
The TLV274QPWRG4Q1 maintains ≥65° phase margin with capacitive loads up to 10 pF. For loads exceeding 10 pF, TI recommends adding a series null resistor (RNULL ≥ 20 Ω) between the output pin and the load capacitance. This configuration preserves stability in applications like driving long PCB traces or LCD bias networks, and is validated in Figure 16 of the SGLS275A datasheet. TLV274QPWRG4Q1's internal compensation is optimized for unity-gain stability under these conditions.
Does TLV274QPWRG4Q1 support true rail-to-rail input operation?
No, TLV274QPWRG4Q1 features rail-to-rail *output* only. Its common-mode input voltage range extends from 0 V to VDD − 1.35 V, meaning the inputs cannot accept signals within 1.35 V of the positive rail. This limitation is explicitly stated in the "Recommended Operating Conditions" table (page 5). For full rail-to-rail input capability, consider alternatives like the TLV2374-Q1. TLV274QPWRG4Q1's CMOS input stage still enables operation down to GND, making it suitable for single-supply sensor interfaces where the signal stays below VDD − 1.35 V.
What is the guaranteed input offset voltage specification for TLV274QPWRG4Q1 over temperature?
The TLV274QPWRG4Q1 has a maximum input offset voltage of 7 mV across the full −40°C to 125°C automotive temperature range, as specified in the "Electrical Characteristics" table (page 5). At 25°C, the typical value is 0.5 mV with a maximum of 5 mV. Its offset voltage drift is 2 µV/°C, resulting in worst-case drift of ±250 µV over the full range - contributing ≤0.35 mV to total offset error. This performance meets stringent requirements for precision current sensing and thermistor linearization in automotive ECUs.
Can TLV274QPWRG4Q1 be used in dual-supply configurations?
Yes, TLV274QPWRG4Q1 supports dual-supply operation from ±1.35 V to ±8 V, as confirmed in the "Recommended Operating Conditions" table (page 4). This allows symmetric biasing for AC-coupled audio or instrumentation applications in infotainment head units or diagnostic tools. When operated in split-supply mode, the device retains all key specifications: 3-MHz bandwidth, 2.4 V/µs slew rate, and rail-to-rail output swing relative to the negative rail. GND remains the reference node for the substrate and thermal pad.
Is TLV274QPWRG4Q1 pin-compatible with standard TLV274 variants?
Yes, TLV274QPWRG4Q1 is pin-compatible with non-automotive TLV274 variants in the same TSSOP-14 (PW) package, including TLV274IPW and TLV274CPW. All share identical pinout, footprint, and solder mask layout. However, the Q1 suffix denotes AEC-Q100 qualification, enhanced screening, and guaranteed operation from −40°C to 125°C - critical for automotive deployment. Electrical parameters are identical; only reliability and qualification differ. TLV274QPWRG4Q1 replaces TLV274IPW in safety-critical designs without PCB redesign.
