Product details
Overview
TLC2274QDRG4Q1 from Texas Instruments is a quad, rail-to-rail output, LinCMOS™ operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), with 2.2 MHz gain-bandwidth product, 3.6 V/μs slew rate, and 9 nV/√Hz input voltage noise at 1 kHz. It delivers low input bias current (1 pA typical), low input offset voltage (≤950 μV max), and full single- or split-supply operation - enabling precision signal conditioning in automotive body control modules and battery management systems.
For engineers reviewing the TLC2274QDRG4Q1 datasheet, TLC2274QDRG4Q1 pinout, TLC2274QDRG4Q1 application, or TLC2274QDRG4Q1 equivalent, key selection criteria include rail-to-rail output swing, automotive-grade temperature range, functional safety documentation support, low-noise performance for high-impedance sensor interfaces, and SOIC-14 package compatibility with ADC driver and motor control feedback loop designs.
Technical Context
The TLC2274QDRG4Q1 implements a CMOS-input, rail-to-rail output architecture optimized for wide common-mode input range (down to VDD−) and high open-loop gain (>10 V/mV). Its LinCMOS™ process enables ultra-low input bias current while maintaining stable phase margin (≥50°) under 100 pF capacitive load conditions across ±2.2 V to ±8 V supply operation.
It supports both single-supply (VDD = 5 V) and dual-supply (VDD± = ±5 V) configurations, with guaranteed output swing within 15 mV of each rail at ±20 μA load. Input offset voltage is specified up to 950 μV maximum for the 'A' variant, and thermal drift is tightly controlled at 2 μV/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V (dual) or 4.4 V to 16 V (single) - supports 5 V and ±5 V systems without level-shifting. |
| Gain-Bandwidth Product | 2.25 MHz typical at ±5 V - enables stable closed-loop operation up to ~200 kHz with unity-gain stability. |
| Slew Rate | 3.6 V/μs typical - supports fast transient response in motor current sensing and PWM feedback paths. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - 2× lower than competitive CMOS op amps, critical for piezoelectric transducer amplification. |
| Input Offset Voltage | ≤950 μV max (TLC2274A-Q1 variant) - ensures <0.02% error in 5 V full-scale analog front-ends. |
| Common-Mode Input Range | Extends to VDD− - allows direct interfacing with ground-referenced sensors in single-supply automotive ECUs. |
| Output Swing | Within 15 mV of rails at ±20 μA - maximizes dynamic range when driving SAR ADCs with 0–5 V input ranges. |

| 1OUT | Output, channel 1 | Rail-to-rail capable output; drives ≥10 kΩ loads with <15 mV headroom to supply rails. |
| VDD+ | Positive supply | Highest potential supply pin; must be decoupled locally with 0.1 μF ceramic capacitor. |
| VDD– | Negative supply | Lowest potential supply pin; serves as reference for single-supply operation when tied to GND. |
| 3IN+, 3IN–, 3OUT | Inputs/outputs, channel 3 | Identical electrical behavior to channels 1 and 2; fully independent for multi-channel signal chains. |
| 4IN+, 4IN–, 4OUT | Inputs/outputs, channel 4 | Enables four independent gain stages on one die - reduces board space vs discrete op amp solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434-Q1 | Higher supply current (1.2 mA/channel), lower GBW (1.8 MHz), no AEC-Q100 documentation package. | Targeted at cost-sensitive non-safety-critical modules; lacks functional safety report bundle. | Select when BOM cost is prioritized over long-term calibration stability and ISO 26262 traceability. |
| LMV339-Q1 | Quad comparator (not op amp); open-drain outputs; no rail-to-rail input; higher input offset (7 mV). | Used for threshold detection only - cannot replace TLC2274QDRG4Q1 in linear amplification or active filtering roles. | Choose only for discrete voltage window comparators; not a functional substitute for analog signal conditioning. |
Compared with TLV2434-Q1 and LMV339-Q1, the TLC2274QDRG4Q1 uniquely combines AEC-Q100 Grade 1 qualification, functional safety documentation, rail-to-rail output, and sub-10 nV/√Hz noise - making it the only option among the three qualified for precision closed-loop control in ASIL-B automotive subsystems.

FAQ
What is the maximum operating temperature range for the TLC2274QDRG4Q1?
The TLC2274QDRG4Q1 is qualified to AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, slew rate, and common-mode input range, ensuring reliable performance in under-hood automotive environments where the TLC2274QDRG4Q1 is commonly deployed.
Does the TLC2274QDRG4Q1 support single-supply operation?
Yes, the TLC2274QDRG4Q1 is fully specified for single-supply operation from 4.4 V to 16 V. Its common-mode input range extends to the negative rail (VDD−), and its rail-to-rail output can swing within 15 mV of both supply rails - enabling direct interface with 0–5 V ADCs without external level-shifting circuitry. This capability is confirmed in Sections 6.5 and 6.7 of the official datasheet.
Is the TLC2274QDRG4Q1 pin-compatible with the TLC2274A-Q1?
Yes, the TLC2274QDRG4Q1 and TLC2274A-Q1 share identical SOIC-14 pinouts and package dimensions. The 'A' suffix denotes tighter input offset voltage specification (≤950 μV max vs ≤2500 μV for standard TLC2274-Q1), but electrical pin functions, supply connections, and thermal characteristics remain unchanged - allowing drop-in replacement in existing layouts where enhanced DC precision is required.
What functional safety documentation is available for the TLC2274QDRG4Q1?
Texas Instruments provides functional safety documentation for the TLC2274QDRG4Q1, including FIT rate data, failure mode effect analysis (FMEA), and diagnostic coverage reports - specifically referenced in the datasheet Features section for TLC2272-Q1 and TLC2272A-Q1 variants. While the TLC2274QDRG4Q1 shares the same silicon process and qualification, TI confirms this documentation applies to the full TLC227x-Q1 family per SGLS007G revision history.
Can the TLC2274QDRG4Q1 drive a 10 kΩ load with rail-to-rail output swing?
Yes, the TLC2274QDRG4Q1 delivers rail-to-rail output swing into 10 kΩ loads: at ±20 μA, VOH ≥4.99 V and VOL ≤0.01 V with 5 V supply (Section 6.5), and VOM+ ≥4.99 V and VOM− ≤–4.99 V with ±5 V supply (Section 6.6). These values confirm full dynamic range utilization for driving microcontroller ADC inputs, instrumentation amplifiers, and analog multiplexers without external buffering.
