Product details
Overview
TLV2474QDRQ1 from Texas Instruments is a quad-channel, automotive-grade CMOS rail-to-rail input/output operational amplifier optimized for low-voltage sensor signal conditioning. It delivers 2.8 MHz gain-bandwidth, 600 µA/channel supply current, ±35 mA output drive at 500 mV from rail, 250 µV typical input offset voltage, and operates across −40°C to 125°C - enabling high-precision analog front-ends in battery-powered automotive sensors and medical monitors.
For engineers reviewing the TLV2474QDRQ1 datasheet, TLV2474QDRQ1 pinout, TLV2474QDRQ1 application, or TLV2474QDRQ1 equivalent, key selection criteria include rail-to-rail I/O swing at 2.7–6 V supply, 2.5 pA input bias current for high-impedance sources, thermal robustness in SOP-14 packaging, and AEC-Q100 qualification for under-hood automotive use.
Technical Context
The TLV2474QDRQ1 employs a CMOS input stage with rail-to-rail differential pair architecture, enabling full common-mode input range (0 V to VDD) and rail-to-rail output swing under load. Its unity-gain-stable design supports capacitive loads up to 1000 pF with ≥61° phase margin when properly compensated using external RNULL.
It integrates four independent amplifiers sharing a single 2.7–6 V supply, each consuming only 600 µA while sustaining 1.5 V/µs slew rate and 92 dB large-signal open-loop gain at 5 V - balancing micropower operation with usable AC performance for DC-coupled instrumentation paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, dual-cell alkaline, and 3.3 V/5 V system rails without level-shifting. |
| Gain-Bandwidth Product | 2.8 MHz - enables stable closed-loop gain of 10 up to 280 kHz for anti-aliasing filter interfaces. |
| Input Bias Current | 2.5 pA (typ) - minimizes voltage error in high-Z sensor bridges (e.g., RTDs, piezoresistive elements). |
| Output Drive Capability | ±35 mA at 500 mV from rail - drives 10 kΩ loads to full scale while maintaining <0.5% THD+N at 1 kHz. |
| Input Offset Voltage | 250 µV (typ) - ensures ≤0.5 mV total error in 12-bit ADC front-ends with 2 V reference. |
| Operating Temperature | −40°C to 125°C - qualified per AEC-Q100 Grade 1 for engine control, cabin climate, and ADAS sensor modules. |
| Slew Rate | 1.5 V/µs (typ at 5 V) - supports 100 kHz full-power bandwidth for 1 VPP signals without distortion. |
Pinout & Package
TLV2474QDRQ1 is housed in a 14-pin SOIC (SOP-D) package with exposed thermal pad (PowerPAD™), offering 122.3°C/W junction-to-ambient thermal resistance and compatibility with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Delivers rail-to-rail output swing; requires local 0.1 µF decoupling to GND. |
| 2 | Channel 1 Inverting Input | High-impedance node; trace length must be minimized to reduce noise pickup. |
| 3 | Channel 1 Noninverting Input | Accepts common-mode signals from 0 V to VDD; used for reference-biased sensor inputs. |
| 4 | GND | Analog ground reference; connects to solid ground plane beneath thermal pad. |
| 5 | Channel 2 Noninverting Input | Independent input for second channel; shares same layout rules as Pin 3. |
| 6 | Channel 2 Inverting Input | Used for feedback network connection; avoid routing near noisy digital traces. |
| 7 | Channel 2 Output | Second independent output; supports separate load or cascaded gain stage. |
| 8 | VDD | Positive supply; requires parallel 6.8 µF tantalum + 0.1 µF ceramic decoupling. |
| 9 | Channel 3 Noninverting Input | Third channel input; enables multi-sensor synchronous acquisition. |
| 10 | Channel 3 Inverting Input | Configurable for transimpedance or difference amplifier topologies. |
| 11 | Channel 3 Output | Third output; supports independent signal path for diagnostics or redundancy. |
| 12 | GND | Second ground pin; ties to same ground plane as Pin 4 for low-impedance return path. |
| 13 | Channel 4 Inverting Input | Fourth channel feedback node; routed with matched length to Pin 14 if used differentially. |
| 14 | Channel 4 Noninverting Input | Final channel input; supports quad-channel thermistor array or multi-axis IMU conditioning. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474AQDRQ1 | Lower 1600 µV max input offset voltage (vs. 2400 µV for TLV2474QDRQ1) at full temperature range; otherwise identical specs and pinout. | Preferred for high-accuracy bridge sensor applications where offset drift dominates error budget. | Select TLV2474AQDRQ1 when initial offset calibration is impractical and <1.6 mV total error is required over −40°C to 125°C. |
| LMV324QDRQ1 | Higher 120 µA/channel supply current but wider 1 MHz GBW; rail-to-rail output only (not input); no AEC-Q100 Grade 1 rating. | Suitable for cost-sensitive non-safety-critical automotive body electronics where input rail-to-rail is not needed. | Choose LMV324QDRQ1 only for legacy designs requiring lower quiescent current tolerance and no input common-mode extension to GND/VDD. |
Compared with TLV2474AQDRQ1, the TLV2474QDRQ1 trades tighter offset for broader availability and lower cost; versus LMV324QDRQ1, it provides true rail-to-rail input operation and AEC-Q100 compliance essential for modern ADAS and powertrain subsystems.

FAQ
What is the maximum capacitive load the TLV2474QDRQ1 can drive without oscillation?
The TLV2474QDRQ1 maintains ≥61° phase margin with 1000 pF capacitive load when configured as unity-gain follower with RL = 10 kΩ and proper PCB layout. For loads >10 pF, TI recommends adding a 20–100 Ω series resistor (RNULL) between output and load to preserve stability. This applies identically to all four channels of the TLV2474QDRQ1.
Does the TLV2474QDRQ1 support single-supply operation down to 2.7 V?
Yes, the TLV2474QDRQ1 is fully specified for 2.7 V to 6 V single-supply operation across −40°C to 125°C. At 2.7 V, it retains rail-to-rail input common-mode range (0 V to 2.7 V), 2.8 MHz gain-bandwidth, and ±10 mA output drive capability - making it suitable for coin-cell or energy-harvesting powered systems where TLV2474QDRQ1 operates reliably below 3 V.
How does the thermal performance of TLV2474QDRQ1 compare to standard SOIC packages?
The TLV2474QDRQ1 uses a thermally enhanced SOP-14 PowerPAD™ package with θJA = 122.3°C/W - 30% lower than standard SOIC-14 (θJA ≈ 176°C/W). Its exposed thermal pad must be soldered to ≥68 mil × 70 mil copper area with five 13-mil vias to internal ground plane to achieve rated dissipation of 1022 mW. This thermal advantage is critical for TLV2474QDRQ1 in continuous high-output-drive automotive applications.
Is the TLV2474QDRQ1 pin-compatible with other devices in the TLV247x family?
Yes, all TLV247x quad variants - including TLV2474QDRQ1, TLV2474AQDRQ1, and TLV2474QPWPRQ1 - share identical 14-pin SOIC (D) and TSSOP (PWP) footprints and pinouts. The TLV2474QDRQ1 can be substituted for TLV2474AQDRQ1 without PCB changes, though offset voltage and temperature drift differ. This pin compatibility simplifies second-source qualification for TLV2474QDRQ1 in production designs.
What is the typical input-referred voltage noise of TLV2474QDRQ1 at 1 kHz?
The TLV2474QDRQ1 exhibits 15 nV/√Hz typical equivalent input noise voltage at 1 kHz and 25°C, measured with VDD = 3 V or 5 V. This low noise performance - combined with 2.5 pA input bias current - makes TLV2474QDRQ1 well-suited for amplifying microvolt-level signals from thermocouples, piezoelectric sensors, and biopotential electrodes without significant SNR degradation.
