Product details
Overview
TLC2272AQDRQ1 from Texas Instruments is a dual, rail-to-rail output, precision operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C) for automotive systems. It delivers 2.2 MHz gain-bandwidth, 3.6 V/μs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and ≤950 μV maximum input offset voltage at 25°C - enabling high-fidelity signal conditioning in battery management and engine control units.
For engineers reviewing the TLC2272AQDRQ1 datasheet, TLC2272AQDRQ1 pinout, TLC2272AQDRQ1 application, or TLC2272AQDRQ1 equivalent, this device supports single- or split-supply operation with rail-to-rail output swing, common-mode input range extending to the negative rail, and functional safety documentation support - critical for ISO 26262-compliant analog front-end design.
Technical Context
The TLC2272AQDRQ1 employs LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ.) and high input impedance (>10¹² Ω), making it suitable for interfacing with high-impedance sensors like piezoelectric transducers. Its rail-to-rail output stage operates across supply voltages from ±2.2 V to ±8 V, maintaining full dynamic range even at low headroom.
It features internal compensation for unity-gain stability with 100 pF capacitive load, 50° phase margin, and 10 dB gain margin. The device is fully characterized at both 5 V single supply and ±5 V dual supply, with guaranteed performance over –40°C to 125°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide automotive battery voltage variation including cold-crank and load-dump conditions. |
| Gain-Bandwidth Product | 2.2 MHz typical - enables stable closed-loop operation up to ~200 kHz with moderate gain (e.g., AV = 10). |
| Slew Rate | 3.6 V/μs typical - supports fast transient response in motor current sensing and DC/DC feedback loops. |
| Input Offset Voltage | ≤950 μV max at 25°C - reduces DC error in precision sensor amplification and reference buffering. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - 2× lower than competitive CMOS op amps, critical for low-level audio and ECU sensor signals. |
| Input Bias Current | 1 pA typical - minimizes voltage drop across high-impedance source networks (e.g., thermistor dividers, pH electrodes). |
| Common-Mode Input Range | Extends to VDD− - allows direct interface with ground-referenced sensors without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432QDRQ1 | Higher output drive (±50 mA vs ±20 mA), wider input voltage range (to VDD+ – 0.8 V), but higher input offset (1.5 mV max) and noise (14 nV/√Hz). | Better suited for driving heavy capacitive loads or low-impedance ADC inputs; less optimal for ultra-low-offset sensor buffering. | Select when output current >20 mA or input common-mode range beyond VDD− is required - not a drop-in replacement due to offset/noise trade-off. |
| OPA2333AQDRQ1 | Zero-drift architecture, 2 μV max offset, 0.55 μV/°C drift, but lower GBW (350 kHz) and slew rate (0.16 V/μs); same 1 pA bias and AEC-Q100 Grade 1 rating. | Ideal for DC-critical applications like reference buffers and precision current sensing where bandwidth <100 kHz suffices. | Choose for sub-microvolt offset requirements in static measurements; avoid where >1 MHz signal fidelity is needed. |
Compared with TLV2432QDRQ1 and OPA2333AQDRQ1, the TLC2272AQDRQ1 balances mid-bandwidth (2.2 MHz), ultra-low noise (9 nV/√Hz), and low offset (≤950 μV) - making it optimal for automotive sensor signal chains requiring both speed and precision without zero-drift complexity or excessive cost.

FAQ
What is the maximum operating temperature range for the TLC2272AQDRQ1?
The TLC2272AQDRQ1 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 gain-bandwidth product - ensuring reliable performance in under-hood automotive environments.
Does the TLC2272AQDRQ1 support single-supply operation?
Yes, the TLC2272AQDRQ1 is fully specified for single-supply operation (e.g., 5 V) as well as split-supply (e.g., ±5 V). Its common-mode input voltage range extends to the negative rail (VDD−), and its rail-to-rail output swings within 10 mV of both supply rails - enabling direct interface with single-supply ADCs and microcontrollers without level-shifting circuitry.
What functional safety documentation is available for the TLC2272AQDRQ1?
Texas Instruments provides functional safety documentation for the TLC2272AQDRQ1, including FIT rate data, failure mode effects and diagnostic analysis (FMEDA), and safety manual guidance aligned with ISO 26262 ASIL B requirements. These documents are accessible via TI's product folder and support system-level safety case development for automotive ECUs.
How does the input offset voltage of the TLC2272AQDRQ1 compare to the standard TLC2272QDRQ1?
The TLC2272AQDRQ1 guarantees a maximum input offset voltage of 950 μV at 25°C, whereas the standard TLC2272QDRQ1 has a maximum of 2500 μV under identical conditions. This tighter specification makes the 'A' variant suitable for applications demanding higher DC accuracy - such as precision current sensing and reference buffering - without requiring external trimming or calibration.
Is the TLC2272AQDRQ1 pin-compatible with other devices in the TLC227x-Q1 family?
Yes, the TLC2272AQDRQ1 shares the same SOIC-8 (D) and TSSOP-8 (PW) pinouts as TLC2272QDRQ1, TLC2272IDRQ1, and TLC2272AIDRQ1. All dual variants use identical pin numbering and functions - allowing direct PCB footprint reuse across grade and offset variants, provided thermal and layout constraints remain consistent.
