Product details
Overview
TLC2272AQPWRG4Q1 from Texas Instruments is a dual, rail-to-rail output, precision operational amplifier qualified to AEC-Q100 Grade 1 (–40°C to 125°C), featuring 950 µV max input offset voltage, 9 nV/√Hz input voltage noise at 1 kHz, 3.6 V/µs slew rate, and 2.2 MHz gain-bandwidth product. It operates from ±2.2 V to ±8 V supplies and delivers rail-to-rail output swing for high dynamic range in automotive sensor signal conditioning and ADC interface circuits.
For engineers reviewing the TLC2272AQPWRG4Q1 datasheet, TLC2272AQPWRG4Q1 pinout, TLC2272AQPWRG4Q1 application, or TLC2272AQPWRG4Q1 equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade specifications, and real-world functional alternatives - all aligned with TI's SGLS007G revision G datasheet.
Technical Context
The TLC2272AQPWRG4Q1 uses LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typical) and high input impedance (>10¹² Ω), enabling accurate amplification of high-impedance sources like piezoelectric transducers. Its rail-to-rail output stage supports single-supply (5 V) and split-supply (±5 V) operation without clipping near supply rails.
It integrates internal compensation for unity-gain stability with 100 pF capacitive load, exhibits 75 dB common-mode rejection (CMRR) and 95 dB supply-voltage rejection (kSVR) at 25°C, and maintains phase margin ≥50° across temperature and load conditions - critical for closed-loop stability in engine control and battery monitoring systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 950 µV at 25°C - enables precision DC-coupled signal chains without trimming in body control modules. |
| Slew Rate | 3.6 V/µs typical - supports fast transient response in motor control feedback loops and audio preamplifiers. |
| Gain-Bandwidth Product | 2.2 MHz - allows stable unity-gain operation up to ~2 MHz, suitable for anti-aliasing filters before 1 MSPS ADCs. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - two times lower than competitive CMOS op amps, reducing noise floor in low-level sensor interfaces. |
| Supply Voltage Range | ±2.2 V to ±8 V - accommodates wide automotive battery variation (e.g., cold-crank down to 6 V, load-dump up to 16 V). |
| Common-Mode Input Range | Extends to negative rail (VDD−) - permits direct sensing of ground-referenced signals without level-shifting circuitry. |
| ESD Rating | HBM ±2000 V, CDM ±1000 V - meets AEC-Q100-002/-011 requirements for robustness in automotive assembly and field environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432-Q1 | Higher output drive (±50 mA vs ±500 µA), wider input voltage range (to VDD± − 0.1 V), but higher input offset (1.5 mV max) and noise (18 nV/√Hz). | Better suited for driving heavy capacitive loads or low-impedance networks; less ideal for ultra-low-noise sensor conditioning. | Select TLV2432-Q1 when interfacing with low-impedance actuators or requiring higher output current; avoid for precision low-level analog front-ends. |
| OPA2333-Q1 | Zero-drift architecture (0.02 µV/°C offset drift), lower noise (5.5 nV/√Hz), but lower GBW (350 kHz) and slower slew rate (0.16 V/µs). | Optimized for ultra-stable DC measurements (e.g., current shunt monitoring), not for dynamic signal paths requiring bandwidth >1 MHz. | Choose OPA2333-Q1 for millivolt-level DC accuracy over temperature; select TLC2272AQPWRG4Q1 when both precision and 2.2 MHz bandwidth are required. |
Compared with TLV2432-Q1 and OPA2333-Q1, the TLC2272AQPWRG4Q1 uniquely balances rail-to-rail output, 2.2 MHz bandwidth, 950 µV offset, and 9 nV/√Hz noise - making it optimal for automotive mixed-signal applications demanding both precision and speed, such as engine knock detection and adaptive lighting control.
