Product details
Overview
TLV2474QDRG4Q1 from Texas Instruments is a quad-channel, automotive-qualified CMOS rail-to-rail input/output operational amplifier optimized for low-voltage sensor signal conditioning and data acquisition. 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 from 2.7 V to 6 V across −40°C to 125°C.
For engineers reviewing the TLV2474QDRG4Q1 datasheet, TLV2474QDRG4Q1 pinout, TLV2474QDRG4Q1 application, or TLV2474QDRG4Q1 equivalent, key selection criteria include rail-to-rail I/O swing in 3-V systems, automotive temperature compliance, micropower vs. AC performance trade-off, and quad-channel integration for space-constrained analog front-ends.
Technical Context
The TLV2474QDRG4Q1 implements a CMOS input stage with 2.5 pA typical input bias current and rail-to-rail input common-mode range (0 V to VDD). Its output stage supports true rail-to-rail swing under 10-mA load (within 180 mV of rails) and high-current sourcing/sinking (±35 mA at 500 mV off rail), enabling direct interface with ADCs and low-voltage logic without level-shifting.
It features 1.5 V/µs typical slew rate, 90 dB minimum large-signal open-loop gain (AVD), and 68–90 dB supply voltage rejection ratio (SVR) over 2.7–6 V supply - all specified across the full automotive temperature range (−40°C to 125°C) with AEC-Q100 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent op-amps in single package - reduces board area and inter-channel matching variance in multi-sensor systems. |
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, dual-cell alkaline, and 3.3-V/5-V industrial rails without external regulation. |
| Gain-Bandwidth Product | 2.8 MHz - enables stable unity-gain buffer or closed-loop gain ≥10 up to ~280 kHz for anti-aliasing filter interfaces. |
| Input Offset Voltage (typ) | 250 µV - ensures ≤0.5% error in 50-mV full-scale sensor outputs (e.g., bridge sensors, thermopiles) without trimming. |
| Output Drive Capability | ±35 mA at 500 mV from rail - drives 100-Ω loads directly (e.g., transmission lines, LED bias, DAC buffers) without external transistors. |
| Input Bias Current (typ) | 2.5 pA - preserves high-impedance source integrity (e.g., pH electrodes, photodiodes) with <1-mV error on 1-GΩ sources. |
| Quiescent Current / Channel | 600 µA - enables always-on battery-powered monitoring (e.g., tire pressure sensors) with multi-year runtime on coin cells. |
Pinout & Package
SOP-14 (D package) with exposed thermal pad (PowerPAD™); 8.65 mm × 3.91 mm footprint; RoHS-compliant; rated for 1022 mW power dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Rail-to-rail capable; drives ±35 mA when within 500 mV of supply rails. |
| 2 (IN−1) | Channel 1 inverting input | CMOS input; 2.5 pA bias current; accepts 0 V to VDD common-mode voltage. |
| 3 (IN+1) | Channel 1 non-inverting input | Identical electrical specs to IN−1; used for unity-gain buffers and differential amplifiers. |
| 4 (VDD) | Positive supply | Accepts 2.7–6 V; requires local 0.1-µF ceramic + 6.8-µF tantalum decoupling per TI layout guidelines. |
| 5 (IN+2) | Channel 2 non-inverting input | Independent channel; pin-compatible with other TLV247x variants in D package. |
| 6 (IN−2) | Channel 2 inverting input | Same CMOS input structure as IN−1; supports matched dual-channel configurations. |
| 7 (OUT2) | Channel 2 output | Electrically identical to OUT1; shares no internal coupling with other channels. |
| 8 (GND) | Ground reference | Low-impedance return path; TI recommends solid ground plane with localized removal near inputs/outputs. |
| 9 (OUT3) | Channel 3 output | Third independent output; enables 3-phase current sensing or triple-sensor conditioning in one IC. |
| 10 (IN−3) | Channel 3 inverting input | Supports simultaneous multi-channel acquisition with <100-ns inter-channel skew. |
| 11 (IN+3) | Channel 3 non-inverting input | Matches IN+1/IN+2 electrical characteristics; maintains channel-to-channel offset matching. |
| 12 (VDD) | Positive supply (redundant) | Dual VDD pins reduce supply trace inductance; both must be decoupled independently. |
| 13 (IN+4) | Channel 4 non-inverting input | Enables fourth sensor channel or reference buffer; same 250 µV offset spec as other channels. |
| 14 (OUT4) | Channel 4 output | Full rail-to-rail swing; usable as precision voltage follower for ADC reference buffering. |
Key Features
| Feature | Design Value |

Applications
| Automotive Cabin Pressure Sensing | Portable ECG Signal Conditioning |
|---|---|
Use Scenario: Monitoring cabin air pressure via piezoresistive sensor in HVAC control modules. IC Role / Device Role / Timing Role: Quad op-amp configures two channels as precision instrumentation amps for differential bridge readout, one as low-pass filter, and one as ADC driver. Use Value: Rail-to-rail I/O preserves full 3-V ADC range; 250 µV offset ensures <0.1% pressure measurement error; 600 µA/channel enables always-on monitoring. | Use Scenario: Amplifying and filtering weak biopotential signals (0.5–5 mV) from dry-electrode ECG leads. IC Role / Device Role / Timing Role: First stage: ultra-low-bias current buffer (IN+1/IN−1); second stage: high-gain inverting amp; third/fourth: active filters.

IC Role / Device Role / Timing Role: All four channels used: two for sensor biasing and TIA feedback, one for reference buffer, one for alarm comparator interface. Use Value: 600 µA/channel quiescent current extends AA battery life to >2 years; 250 µV offset minimizes zero-drift calibration frequency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474AQDRQ1 | Lower 1600 µV max input offset (vs. 2400 µV for TLV2474QDRG4Q1); otherwise identical specs and pinout. | Required where DC accuracy dominates - e.g., precision weight scales or medical diagnostics requiring <0.05% gain error. | Select TLV2474AQDRQ1 when offset-critical; TLV2474QDRG4Q1 suffices for general-purpose automotive signal chains. |
| LMV324QDRQ1 | Rail-to-rail output only (not input); 1-MHz GBW; 110-µA/channel; lower drive (±40 mA at 1 V from rail). | Suitable for cost-sensitive, low-bandwidth applications (e.g., basic voltage monitoring) where input rail-to-rail is not required. | Choose LMV324QDRQ1 only if bandwidth <1 MHz and input common-mode range >0.5 V from rail is acceptable. |
Compared with TLV2474AQDRQ1, TLV2474QDRG4Q1 trades 1.4× higher max offset for broader availability and identical AC performance; versus LMV324QDRQ1, it delivers 2.8× higher bandwidth and true rail-to-rail input at 5.5× higher quiescent current - making it optimal for precision, low-voltage, multi-channel systems.

FAQ
What is the operating temperature range for TLV2474QDRG4Q1?
The TLV2474QDRG4Q1 is qualified for automotive applications and operates across −40°C to +125°C ambient temperature. All electrical specifications - including input offset voltage, gain-bandwidth product, and output drive - are guaranteed over this full range per AEC-Q100 Grade 1 requirements.
Does TLV2474QDRG4Q1 support true rail-to-rail input and output?
Yes, TLV2474QDRG4Q1 features CMOS input stage and complementary output stage enabling rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 180 mV of rails at 10 mA). This allows full utilization of 3-V ADC input spans without external level-shifting circuitry.
What is the maximum capacitive load TLV2474QDRG4Q1 can drive stably?
TLV2474QDRG4Q1 remains stable with capacitive loads ≤10 pF directly at the output. For larger loads (e.g., 100-pF cable capacitance), TI recommends adding a 20–100 Ω series resistor (RNULL) between the output pin and load - as documented in Figure 34 of the SGLS180B datasheet - to maintain ≥60° phase margin.
How does TLV2474QDRG4Q1 compare to standard TLV2474 in terms of qualification?
TLV2474QDRG4Q1 is the automotive-grade variant with AEC-Q100 qualification, enhanced ESD protection (>2 kV HBM), and guaranteed operation from −40°C to 125°C. Standard TLV2474 (non-Q suffix) is commercial-grade (0°C to 70°C) and lacks automotive process controls and test coverage.
Can TLV2474QDRG4Q1 replace LM2902QDRQ1 in existing designs?
TLV2474QDRG4Q1 is not a drop-in replacement for LM2902QDRQ1 due to different input architecture (CMOS vs. bipolar), supply range (2.7–6 V vs. 3–32 V), and pinout (SOP-14 vs. SOP-14 but channel ordering differs). While both are quad op-amps, TLV2474QDRG4Q1 requires redesign for 3-V operation and rail-to-rail signal chain optimization.
