Product details
Overview
TLC2274QPWRQ1 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 - used in automotive body control modules, battery management systems, and engine control units.
For engineers reviewing the TLC2274QPWRQ1 datasheet, TLC2274QPWRQ1 pinout, TLC2274QPWRQ1 application, or TLC2274QPWRQ1 equivalent, key selection criteria include rail-to-rail output swing, low 1 pA typical input bias current, ±2.2 V to ±8 V supply range, functional safety documentation support, and SOIC-14/TSSOP-14 package compatibility for space-constrained automotive PCB layouts.
Technical Context
The TLC2274QPWRQ1 implements a CMOS-input, rail-to-rail output architecture optimized for precision signal conditioning in single- or split-supply automotive environments. It delivers 2.2 MHz bandwidth and 3.6 V/μs slew rate while maintaining low 950 μV maximum input offset voltage (TLC2274A-Q1 variant) and 9 nV/√Hz noise performance.
Its common-mode input range extends to the negative rail, enabling direct interfacing with low-side current-sense amplifiers and piezoelectric transducers. The device supports full operation across –40°C to 125°C ambient temperature and includes ESD protection rated per AEC-Q100 HBM (±2000 V) and CDM (±1000 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports dual-rail automotive systems including 5 V and ±5 V rails without level-shifting. |
| Gain-Bandwidth Product | 2.2 MHz - enables stable closed-loop operation up to ~200 kHz with unity-gain stability and 100 pF load. |
| Slew Rate | 3.6 V/μs - ensures <2.6 μs settling to 0.01% for 2 V step, suitable for fast sensor signal buffering. |
| Input Offset Voltage | ≤950 μV max (TLC2274A-Q1) - reduces DC error in precision current sensing and ADC front-end applications. |
| Input Bias Current | 1 pA typical - preserves high-impedance source integrity (e.g., pH sensors, thermopiles) without loading. |
| Input Voltage Noise | 9 nV/√Hz @ 1 kHz - two times lower than competitive CMOS op amps, critical for low-level analog signal fidelity. |
| Common-Mode Input Range | Extends to VDD− - allows direct connection to ground-referenced sensors and shunt-based current monitors. |

FAQ
What is the maximum operating temperature range for the TLC2274QPWRQ1?
The TLC2274QPWRQ1 is qualified to AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating applies to both SOIC-14 and TSSOP-14 packages and is validated across all electrical parameters in the datasheet's recommended operating conditions table.
Does the TLC2274QPWRQ1 support single-supply operation?
Yes, the TLC2274QPWRQ1 is fully specified for single-supply operation, with common-mode input voltage range extending to the negative rail (VDD−) and rail-to-rail output swing. It operates from 4.4 V to 16 V single supply, enabling use in 5 V, 12 V, and 24 V automotive subsystems without dual-rail generation.
Is the TLC2274QPWRQ1 pin-compatible with the TLC2274AQPWRQ1?
Yes, the TLC2274QPWRQ1 and TLC2274AQPWRQ1 share identical pinout, package dimensions, and absolute maximum ratings. The primary difference is input offset voltage specification: TLC2274QPWRQ1 has ≤2.5 mV max, while TLC2274AQPWRQ1 is tighter at ≤950 μV max - both in TSSOP-14 packaging.
What functional safety documentation is available for the TLC2274QPWRQ1?
Texas Instruments provides functional safety documentation for the TLC2274QPWRQ1 family, including FIT rate data, failure mode effects and diagnostic analysis (FMEDA) reports, and safety manual excerpts - all accessible via TI's functional safety resource center. These materials support ISO 26262 ASIL-B system-level development.
Can the TLC2274QPWRQ1 drive a 10 kΩ load to rail in a ±5 V configuration?
Yes, the TLC2274QPWRQ1 delivers rail-to-rail output swing into 10 kΩ loads under ±5 V supply. At IO = ±200 μA, VOH ≥ 4.85 V and VOL ≤ –4.85 V are guaranteed - achieving >97% of full-scale swing. Performance degrades only under heavy loads (>1 mA), where output voltage remains within 1.5 V of rails.
