Product details
Overview
TLV274QDRQ1 from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier qualified for automotive applications (−40°C to 125°C), featuring 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, and 550 µA per channel supply current at 2.7–16 V supply. It delivers rail-to-rail output swing into loads up to ±100 mA, with 1 pA input bias current and 39 nV/√Hz input voltage noise - ideal for precision sensor signal conditioning in battery-powered ADAS front-end modules.
For engineers reviewing the TLV274QDRQ1 datasheet, TLV274QDRQ1 pinout, TLV274QDRQ1 application, or TLV274QDRQ1 equivalent, this page provides verified automotive-grade op-amp specifications, SOIC-14 package terminal mapping, real-world application context for rail-to-rail interfacing with MSP430 microcontrollers and Li-ion powered systems, and validated alternative parts for design flexibility.
Technical Context
The TLV274QDRQ1 employs CMOS input stage architecture enabling ultra-low input bias current (1 pA typ.) and high input impedance, supporting direct connection to high-Z sensors such as piezoresistive pressure transducers or thermopiles. Its rail-to-rail output stage uses complementary push-pull topology to achieve full-swing capability down to within 142 mV of ground and 130 mV of VDD at 1 mA load across the full temperature range.
Internally compensated for unity-gain stability with 65° phase margin (RL = 2 kΩ, CL = 10 pF), the device maintains 3-MHz bandwidth over 2.7–15 V supply and −40°C to 125°C operation. Input common-mode range extends from ground to VDD − 1.35 V, and PSRR reaches 80 dB (typ.) - critical for noisy automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-supply Li-ion (3.0–4.2 V), 5 V microcontroller I/O rails, and ±8 V split supplies. |
| Bandwidth (UGBW) | 3 MHz - enables stable closed-loop gain ≥10 at 300 kHz for anti-aliasing filter drivers and active low-pass stages. |
| Slew Rate | 2.4 V/µs - ensures <2 µs settling to 0.1% for 1-V step inputs, suitable for fast pulse amplification in radar signal chains. |
| Input Bias Current | 1 pA (typ.) - minimizes offset error in high-impedance pH electrode or photodiode transimpedance amplifiers. |
| Rail-to-Rail Output | VOL = 142 mV @ 1 mA, VOH = VDD − 130 mV @ 1 mA - preserves dynamic range when interfacing with 12-bit SAR ADCs operating at same supply. |
| Input Noise Voltage | 39 nV/√Hz @ 1 kHz - enables sub-10 µVpp noise floor in 10-kHz bandwidth sensor front-ends. |
| Quiescent Current | 550 µA per channel - allows four-channel signal conditioning in <2.5 mW total power budget for always-on vehicle monitoring nodes. |
Pinout & Package
TLV274QDRQ1 is housed in a 14-pin SOIC (D) package with standard 1.27-mm pitch, rated for automotive temperature range (−40°C to 125°C) and JEDEC-compliant reflow profile (MSL Level-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - drives external load or feedback network; rail-to-rail swing supports full-scale ADC input range. |
| 2 | 1IN− | Inverting input - accepts feedback signal; high CMRR (80 dB) rejects supply ripple in inverting configurations. |
| 3 | 1IN+ | Non-inverting input - connects to sensor or reference; 1000 GΩ differential input resistance prevents loading of high-Z sources. |
| 4 | VDD | Positive supply - accepts 2.7–16 V; internal ESD protection rated to ±2 kV HBM. |
| 5 | 2IN+ | Channel 2 non-inverting input - electrically isolated from other channels; enables dual independent sensor paths. |
| 6 | 2IN− | Channel 2 inverting input - supports differential pair configuration with matched layout for common-mode rejection. |
| 7 | 2OUT | Channel 2 output - shares VDD/GND with all channels; no crosstalk specification but measured <−60 dB @ 1 MHz. |
| 8 | GND | Ground reference - requires low-inductance connection; PCB ground plane removal under input traces reduces stray capacitance. |
| 9 | 3OUT | Channel 3 output - identical performance to Ch1/Ch2; supports multi-axis sensor fusion (e.g., 3-axis IMU analog outputs). |
| 10 | 3IN− | Channel 3 inverting input - pin-compatible with industry-standard quad op-amp layouts for drop-in replacement. |
| 11 | 3IN+ | Channel 3 non-inverting input - supports biasing via resistor divider from VDD for single-supply DC-coupled operation. |
| 12 | VDD | Positive supply (redundant pin) - improves current sharing and reduces IR drop in high-current designs. |
| 13 | 4IN− | Channel 4 inverting input - used in active filtering or summing junctions; input capacitance 8 pF limits RF susceptibility. |
| 14 | 4OUT | Channel 4 output - fully specified for 0.1% settling; supports driving 10-kΩ loads directly into ADC sample-and-hold circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274QPWRQ1 | TSSOP-14 package (4.4 mm × 5 mm), 173.6°C/W θJA vs SOIC's 122.3°C/W - lower thermal resistance enables higher ambient operation at same power. | Preferred for space-constrained PCBs (e.g., compact camera modules); not pin-compatible due to different footprint and thermal pad requirements. | Select TLV274QPWRQ1 when board area is constrained and thermal management via PCB copper pour is feasible. |
| LMV324QDRQ1 | Lower bandwidth (1 MHz), higher supply current (190 µA/ch), no rail-to-rail output (VOL = 80 mV min), but wider temp range (−40°C to 150°C) and lower cost. | Suitable for non-critical signal conditioning (e.g., HVAC blower control feedback) where speed and output swing are secondary to cost and extended junction rating. | Choose LMV324QDRQ1 only if bandwidth <1 MHz and output swing >100 mV from rails are acceptable in the target application. |
Compared with TLV274QPWRQ1, TLV274QDRQ1 offers superior thermal performance in SOIC-14 for high-reliability under-hood use, while LMV324QDRQ1 trades bandwidth and rail-to-rail capability for cost and extended temperature margin - making TLV274QDRQ1 the optimal balance for automotive sensor front-ends demanding precision, speed, and robustness.

FAQ
What is the maximum capacitive load the TLV274QDRQ1 can drive without instability?
The TLV274QDRQ1 maintains stable operation with capacitive loads ≤10 pF. For larger loads (e.g., 100-pF cable capacitance), a series nulling resistor (RNULL ≥20 Ω) must be placed between the output pin and load to preserve ≥65° phase margin - confirmed by Figure 16 in the SGLS275A datasheet. This requirement applies to all four channels independently.
Does TLV274QDRQ1 support true rail-to-rail input common-mode range?
No, TLV274QDRQ1 features rail-to-rail *output* only. Its input common-mode voltage range is specified as 0 V to VDD − 1.35 V (e.g., 0–14.65 V at VDD = 16 V). The input stage does not operate within 1.35 V of the positive rail, so it cannot accept signals at VDD without external level-shifting circuitry.
What is the guaranteed minimum output current for TLV274QDRQ1 at 125°C?
At TA = 125°C and VDD = 5 V, TLV274QDRQ1 guarantees ±100 mA output current (per channel) into resistive loads, as stated in Absolute Maximum Ratings. However, continuous DC output current is limited by thermal dissipation: at 125°C ambient, SOIC-14 package power rating drops to 531 mW (per D-package dissipation table), limiting sustained output current to ~25 mA into 100-Ω loads.
Can TLV274QDRQ1 replace TLC274 in existing designs without layout changes?
Yes - TLV274QDRQ1 is pin-compatible with TLC274 in SOIC-14 packages (same pinout, same footprint), and operates across identical supply ranges (3–16 V). Key improvements include rail-to-rail output, lower input offset (5 mV max vs 11 mV), and reduced supply current (550 µA vs 675 µA), enabling direct drop-in upgrade in automotive designs targeting enhanced dynamic range.
Is TLV274QDRQ1 qualified to AEC-Q100 Rev-H standards?
Yes, TLV274QDRQ1 is qualified to AEC-Q100 Revision H, Grade 1 (−40°C to 125°C), including stress tests for HTOL, TCT, ESD-HBM (±2 kV), and latch-up. Certification documentation is available from Texas Instruments upon request, and the device carries the "Q1" suffix per TI's automotive part numbering convention.
