Product details
Overview
TLC2272AQPWRQ1 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, 2.2 MHz gain-bandwidth product, and 3.6 V/µs slew rate. It operates from ±2.2 V to ±8 V supplies and is optimized for automotive signal conditioning in battery management, engine control, and body electronics.
For engineers reviewing the TLC2272AQPWRQ1 datasheet, TLC2272AQPWRQ1 pinout, TLC2272AQPWRQ1 application, or TLC2272AQPWRQ1 equivalent, key selection criteria include its rail-to-rail output swing, low 1 pA typical input bias current, functional safety documentation support, and validated performance across automotive temperature extremes.
Technical Context
The TLC2272AQPWRQ1 employs LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), ultra-low input bias current (1 pA typ), and rail-to-rail output capability-enabling full dynamic range utilization with single- or split-supply configurations. Its common-mode input voltage range extends to the negative rail, supporting ground-referenced sensor interfacing.
Designed for precision analog signal conditioning, it delivers 75 dB typical CMRR and 95 dB typical PSRR at 25°C under ±5 V operation, with stable unity-gain performance (52° phase margin) into 100 pF capacitive loads-critical for driving ADC inputs and maintaining signal integrity in noisy automotive environments.
Key Specifications

|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide automotive battery voltage fluctuations and dual-rail sensor interfaces |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables accurate DC-coupled amplification in precision current sensing and voltage monitoring |
| Gain-Bandwidth Product | 2.25 MHz at ±5 V - sufficient for anti-aliasing filtering and closed-loop control up to ~200 kHz |
| Slew Rate | 3.6 V/µs typ - ensures faithful reproduction of fast transients in motor control feedback and audio pre-amplification |
| Input Voltage Noise | 9 nV/√Hz at f = 1 kHz - 2× lower than competitive CMOS op amps, critical for low-level piezoelectric or thermocouple signal conditioning |
| Common-Mode Input Range | Extends to VDD− - allows direct interface with ground-referenced sensors without level-shifting circuitry |
| Output Swing | Rail-to-rail - maximizes ADC input utilization and simplifies supply rail design in 3.3 V or 5 V systems |

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 |
|---|---|---|---|
| TLV2432-Q1 | Higher output drive (±50 mA vs ±5 mA), wider input voltage range (to VDD± − 1.5 V), but higher input offset (1.5 mV max) and noise (12 nV/√Hz) | Better suited for driving heavy capacitive loads or low-impedance actuators; less optimal for ultra-low-noise sensor front-ends | Select TLV2432-Q1 when output current >5 mA or input common-mode range beyond VDD− is required |
| TLC2272-Q1 | Same package and pinout, but higher input offset voltage (2.5 mV max) and no functional safety documentation bundle | Acceptable for non-safety-critical signal paths where cost sensitivity outweighs offset/noise requirements | Choose TLC2272-Q1 only if functional safety compliance and sub-millivolt offset are not mandated by system architecture |
Compared with TLC2272AQPWRQ1, TLV2432-Q1 trades precision for drive strength and input range, while TLC2272-Q1 reduces cost at the expense of offset accuracy and safety certification-making TLC2272AQPWRQ1 the optimal choice for ASIL-B–aligned, low-noise automotive signal chains.

FAQ
What is the maximum input offset voltage specification for TLC2272AQPWRQ1?
The TLC2272AQPWRQ1 has a maximum input offset voltage of 950 µV at TA = 25°C, and 1500 µV across the full operating temperature range (–40°C to 125°C). This tighter spec distinguishes it from the standard TLC2272-Q1 (2500 µV max at 25°C) and supports precision applications like current sensing and sensor signal conditioning where DC accuracy is critical. The value is guaranteed per TI's SGLS007G datasheet Section 6.5.
Does TLC2272AQPWRQ1 support single-supply operation?
Yes, TLC2272AQPWRQ1 is fully specified for single-supply operation, with a recommended supply range of 4.4 V to 16 V (VDD = 4.4 V to 16 V). Its common-mode input voltage range includes the negative rail (VDD−), and output swings rail-to-rail-enabling use in 5 V or 12 V automotive systems without negative supply rails. This is confirmed in Sections 6.3 and 6.5 of the official datasheet.
What package type is used for TLC2272AQPWRQ1?
TLC2272AQPWRQ1 uses the PW (TSSOP-8) package, with nominal dimensions of 3.00 mm × 4.40 mm. This surface-mount package is RoHS-compliant, qualified for automotive reflow profiles, and listed explicitly in the "Package Information" table of the SGLS007G datasheet. It is distinct from the SOIC-8 (D) variant and shares pinout compatibility with other TLC2272x-Q1 variants in the same footprint.
Is functional safety documentation available for TLC2272AQPWRQ1?
Yes, functional safety documentation-including FIT rate data, failure mode effects analysis (FMEA), and diagnostic coverage guidance-is available for TLC2272AQPWRQ1 to support ISO 26262 ASIL-B system development. This is explicitly stated in the "Features" section of the datasheet and differentiated from the base TLC2272-Q1, which lacks this documentation bundle. TI provides these materials via their functional safety portal upon request.
What is the typical input voltage noise of TLC2272AQPWRQ1 at 1 kHz?
The typical input voltage noise of TLC2272AQPWRQ1 is 9 nV/√Hz at f = 1 kHz, as specified in Sections 6.5 and 6.6 of the SGLS007G datasheet. This value is measured under ±5 V or 5 V supply conditions at TA = 25°C and is 2× lower than competing CMOS op amps-making it especially suitable for amplifying low-amplitude signals from piezoelectric transducers, thermocouples, or bridge sensors in automotive environments.
